开发步骤：

一、创建工程

在这里插入图片描述

二、数据库连接操作

1.所需包结构

在这里插入图片描述

2.在model包中创建Db类

作用：用于接受前端传来数据库连接相关的值(username，password,url)

package com.example.generate_code.model;

/**
 * @author: 王泽
 */

public class Db {
    private String username;
    private String password;
    private String url;


    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }
}

3.在model中创建RespBean类

自定义响应类，返回数据更方便

package com.example.generate_code.model;

/**
 * @author: 王泽
 */

public class RespBean {
    private Integer status;
    private String msg;
    private Object obj;

    public static RespBean ok(String msg,Object obj) {
        return new RespBean(200, msg, obj);
    }


    public static RespBean ok(String msg) {
        return new RespBean(200, msg, null);
    }


    public static RespBean error(String msg,Object obj) {
        return new RespBean(500, msg, obj);
    }


    public static RespBean error(String msg) {
        return new RespBean(500, msg, null);
    }

    private RespBean() {
    }

    private RespBean(Integer status, String msg, Object obj) {
        this.status = status;
        this.msg = msg;
        this.obj = obj;
    }

    public Integer getStatus() {
        return status;
    }

    public void setStatus(Integer status) {
        this.status = status;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public Object getObj() {
        return obj;
    }

    public void setObj(Object obj) {
        this.obj = obj;
    }


}

4.在Utils中创建DBUtils

JDBC连接工具类

public class DbUtils {
    private static Connection connection;

    public static Connection getConnection() {
        return connection;
    }

    public static Connection initDb(Db db) {
        if (connection == null) {
            try {
                Class.forName("com.mysql.cj.jdbc.Driver");
                connection = DriverManager.getConnection(db.getUrl(), db.getUsername(), db.getPassword());
            } catch (ClassNotFoundException | SQLException e) {
                e.printStackTrace();
            }
        }
        return connection;
    }


}

5.写一个连接接口DbController

连接数据库

@RestController
public class DbController {
    @PostMapping("/connect")
    public RespBean connect(@RequestBody Db db) {
        Connection con = DBUtils.initDb(db);
        if (con != null) {
            return RespBean.ok("数据库连接成功");
        }
        return RespBean.error("数据库连接失败");
    }
}

6.创建index页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>代码生成工具</title>
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
    <!-- 引入样式 -->
    <link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
    <!-- 引入组件库 -->
    <script src="https://unpkg.com/element-ui/lib/index.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
</head>
<body>
<div id="app">
    <table>
        <tr>
            <td>
                <el-tag size="mini">数据库用户名：</el-tag>
            </td>
            <td>
                <el-input size="mini" v-model="db.username"></el-input>
            </td>
        </tr>
        <tr>
            <td>
                <el-tag size="mini">数据库密码：</el-tag>
            </td>
            <td>
                <el-input size="mini" v-model="db.password"></el-input>
            </td>
        </tr>
        <tr>
            <td>
                <el-tag size="mini">数据库连接地址：</el-tag>
            </td>
            <td>
                <el-input size="mini" v-model="db.url">
                    <template slot="prepend">jdbc:mysql://</template>
                    <template slot="append">
                        ?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
                    </template>
                </el-input>
            </td>
        </tr>
    </table>
    <div style="display: flex">
        <el-button type="primary" size="mini" @click="connect" :disabled="!connectBtnEnabled">连接数据库</el-button>
        <div style="color: #ff018d;font-weight: bold">[{{msg}}]</div>
        <el-input v-model="packageName" size="mini" style="width: 300px"></el-input>
        <el-button type="primary" size="mini" @click="config">配置</el-button>
    </div>
</div>
<script>
    new Vue({
        el: "#app",
        data: function () {
            return {
                packageName: '',
                msg: '数据库未连接',
                connectBtnEnabled: true,
                db: {
                    username: "root",
                    password: "123456",
                    url: "localhost:3306/"
                }
            }
        },
        methods: {
           
            connect() {
                let _this = this;
                this.db.url = "jdbc:mysql://" + this.db.url + "?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai";
                axios.post('/connect', this.db)
                    .then(function (response) {
                        _this.msg = response.data.msg;
                        _this.db = {
                            username: "root",
                            password: "123456",
                            url: "localhost:3306/"
                        }
                        _this.connectBtnEnabled = false;
                    })
                    .catch(function (error) {
                        console.log(error);
                    });
            }
        }
    })
</script>
</body>
</html>

在这里插入图片描述

三、加载数据表信息

1.服务器端编写

ColumnClass 用来描述表中的每一列

package com.example.generate_code.model;

/**
 * @author: 王泽
 */

public class ColumnClass {
    private String propertyName; //对应java属性的名字
    private String columnName;  //数据库中的名字
    private String type;        //字段类型
    private String remark;      //备注
    private Boolean isPrimary;  //字段是不是一个主键

    @Override
    public String toString() {
        return "ColumnClass{" +
                "propertyName='" + propertyName + '\'' +
                ", columnName='" + columnName + '\'' +
                ", type='" + type + '\'' +
                ", remark='" + remark + '\'' +
                ", isPrimary=" + isPrimary +
                '}';
    }

    public String getPropertyName() {
        return propertyName;
    }

    public void setPropertyName(String propertyName) {
        this.propertyName = propertyName;
    }

    public String getColumnName() {
        return columnName;
    }

    public void setColumnName(String columnName) {
        this.columnName = columnName;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }

    public Boolean getPrimary() {
        return isPrimary;
    }

    public void setPrimary(Boolean primary) {
        isPrimary = primary;
    }


}

描述一个具体的表的信息 TableClass

package com.example.generate_code.model;

import java.util.List;

/**
 * @author: 王泽
 */

public class TableClass {
    private String tableName;  //表名 ，以下是生成的名字
    private String modelName;
    private String serviceName;
    private String mapperName;
    private String controllerName;
    private String packageName;
    private List<ColumnClass> columns; // 字段

    @Override
    public String toString() {
        return "TableClass{" +
                "tableName='" + tableName + '\'' +
                ", modelName='" + modelName + '\'' +
                ", serviceName='" + serviceName + '\'' +
                ", mapperName='" + mapperName + '\'' +
                ", controllerName='" + controllerName + '\'' +
                ", packageName='" + packageName + '\'' +
                ", columns=" + columns +
                '}';
    }

    public String getTableName() {
        return tableName;
    }

    public void setTableName(String tableName) {
        this.tableName = tableName;
    }

    public String getModelName() {
        return modelName;
    }

    public void setModelName(String modelName) {
        this.modelName = modelName;
    }

    public String getServiceName() {
        return serviceName;
    }

    public void setServiceName(String serviceName) {
        this.serviceName = serviceName;
    }

    public String getMapperName() {
        return mapperName;
    }

    public void setMapperName(String mapperName) {
        this.mapperName = mapperName;
    }

    public String getControllerName() {
        return controllerName;
    }

    public void setControllerName(String controllerName) {
        this.controllerName = controllerName;
    }

    public String getPackageName() {
        return packageName;
    }

    public void setPackageName(String packageName) {
        this.packageName = packageName;
    }

    public List<ColumnClass> getColumns() {
        return columns;
    }

    public void setColumns(List<ColumnClass> columns) {
        this.columns = columns;
    }

}

创建配置接口Controller

用map来接受前端传来的数据

用到了谷歌提供的工具包guava，需要导入依赖

 @PostMapping("/config")
    public RespBean config(@RequestBody Map<String, String> map) {
        String packageName = map.get("packageName");
        try {
            Connection connection = DBUtils.getConnection();
            DatabaseMetaData metaData = connection.getMetaData();
            ResultSet tables = metaData.getTables(connection.getCatalog(), null, null, null);
            List<TableClass> tableClassList = new ArrayList<>();
            while (tables.next()) {
                TableClass tableClass = new TableClass();
                tableClass.setPackageName(packageName);
                String table_name = tables.getString("TABLE_NAME");
                String modelName = CaseFormat.LOWER_UNDERSCORE.to(CaseFormat.UPPER_CAMEL, table_name);
                tableClass.setTableName(table_name);
                tableClass.setModelName(modelName);
                tableClass.setControllerName(modelName + "Controller");
                tableClass.setMapperName(modelName + "Mapper");
                tableClass.setServiceName(modelName+"Service");
                tableClassList.add(tableClass);
            }
            return RespBean.ok("数据库信息读取成功", tableClassList);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return RespBean.error("数据库信息读取失败");
    }

<dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>30.1-jre</version>
        </dependency>

2.完善index页面

                        _this.msg = response.data.msg;
                        _this.db = {
                            username: "root",

四、代码生成

1.创建模板 Model.java.ftl

package ${packageName}.model;

import java.util.Date;

public class ${modelName}{

    <#if columns??>
        <#list columns as column>
            <#if column.type='VARCHAR'||column.type='TEXT'||column.type='CHAR'>
                /**
                * ${column.remark}
                */
                private String ${column.propertyName?uncap_first};
            </#if>
            <#if column.type='INT'>
                /**

                */
                private Integer ${column.propertyName?uncap_first};
            </#if>
            <#if column.type='DATETIME'>
                /**

            </#if>
            <#if column.type='BIT'>
                /**
                * ${column.remark}
                */
                private Boolean ${column.propertyName?uncap_first};
            </#if>
        </#list>
    </#if>
    <#if columns??>
        <#list columns as column>
            <#if column.type='VARCHAR'||column.type='TEXT'||column.type='CHAR'>
                public String get${column.propertyName}(){
                    return ${column.propertyName?uncap_first};
                }
                public void set${column.propertyName}(String ${column.propertyName?uncap_first}){
                    this.${column.propertyName?uncap_first}=${column.propertyName?uncap_first};
                }
            </#if>
            <#if column.type='INT'>
                public Integer get${column.propertyName}(){
                return ${column.propertyName?uncap_first};
                }
                public void set${column.propertyName}(Integer ${column.propertyName?uncap_first}){
                this.${column.propertyName?uncap_first}=${column.propertyName?uncap_first};
                }
            </#if>
            <#if column.type='DATETIME'>

                }
                public void set${column.propertyName}(Date ${column.propertyName?uncap_first}){
                this.${column.propertyName?uncap_first}=${column.propertyName?uncap_first};
                }
            </#if>

                public Long get${column.propertyName}(){
                return ${column.propertyName?uncap_first};
                }
                public void set${column.propertyName}(Long ${column.propertyName?uncap_first}){
                this.${column.propertyName?uncap_first}=${column.propertyName?uncap_first};

            </#if>
            <#if column.type='DOUBLE'>

                }
                public void set${column.propertyName}(Double ${column.propertyName?uncap_first}){
                this.${column.propertyName?uncap_first}=${column.propertyName?uncap_first};
                }
            </#if>
            <#if column.type='BIT'>
                public Boolean get${column.propertyName}(){
                return ${column.propertyName?uncap_first};
                }
                public void set${column.propertyName}(Boolean ${column.propertyName?uncap_first}){
                this.${column.propertyName?uncap_first}=${column.propertyName?uncap_first};
                }
            </#if>
        </#list>
    </#if>
}

Service.java.ftl

package ${packageName}.service;

import ${packageName}.model.${modelName};
import ${packageName}.mapper.${mapperName};
import org.springframework.stereotype.Service;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.List;

@Service
public class ${serviceName}{

    @Autowired
    ${mapperName} ${mapperName?uncap_first};
    public List<${modelName}> getAll${modelName}s(){
        return ${mapperName?uncap_first}.getAll${modelName}s();
    }
}

Controller.java.ftl

package ${packageName}.controller;

import ${packageName}.model.${modelName};
import ${packageName}.service.${serviceName};
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.List;

@RestController
public class ${controllerName}{

    @Autowired
    ${serviceName} ${serviceName?uncap_first};

    @GetMapping("/${modelName?lower_case}s")
    public List<${modelName}> getAll${modelName}s(){
        return ${serviceName?uncap_first}.getAll${modelName}s();
    }
}

Mapper.java.ftl

package ${packageName}.mapper;

import ${packageName}.model.${modelName};
import org.apache.ibatis.annotations.Mapper;
import java.util.List;

@Mapper
public interface ${mapperName}{
    List<${modelName}> getAll${modelName}s();
}

Mapper.xml.ftl

<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="${packageName}.mapper.${mapperName}">

    <resultMap id="BaseResultMap" type="${packageName}.model.${modelName}">
        <#list columns as column>
            <<#if column.primary??>id<#else>result</#if> column="${column.columnName}" property="${column.propertyName?uncap_first}" jdbcType="<#if column.type='INT'>INTEGER<#elseif column.type='DATETIME'>TIMESTAMP<#elseif column.type='TEXT'>VARCHAR<#else>${column.type}</#if>" />

    </resultMap>

    <select id="getAll${modelName}s" resultMap="BaseResultMap">
        select * from ${tableName};
    </select>
</mapper>

2.代码生成Controller

package com.example.generate_code.controller;
import com.example.generate_code.model.RespBean;
import com.example.generate_code.model.TableClass;
import com.example.generate_code.service.GenerateCodeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

@RestController
public class GenerateCodeController {
    @Autowired
    GenerateCodeService generateCodeService;


    @PostMapping("/generateCode")
    public RespBean generateCode(@RequestBody List<TableClass> tableClassList, HttpServletRequest req) {
        return generateCodeService.generateCode(tableClassList, req.getServletContext().getRealPath("/"));
    }
}

3.编写service

package com.example.generate_code.service;

import com.example.generate_code.model.ColumnClass;
import com.example.generate_code.model.RespBean;
import com.example.generate_code.model.TableClass;
import com.example.generate_code.utils.DBUtils;
import com.google.common.base.CaseFormat;
import freemarker.cache.ClassTemplateLoader;
import freemarker.template.Configuration;
import freemarker.template.Template;

        cfg.setTemplateLoader(new ClassTemplateLoader(GenerateCodeService.class, "/templates"));
        cfg.setDefaultEncoding("UTF-8");
    }

    public RespBean generateCode(List<TableClass> tableClassList, String realPath) {
        try {
            Template modelTemplate = cfg.getTemplate("Model.java.ftl");
            Template mapperJavaTemplate = cfg.getTemplate("Mapper.java.ftl");

                ResultSet primaryKeys = metaData.getPrimaryKeys(connection.getCatalog(), null, tableClass.getTableName());
                List<ColumnClass> columnClassList = new ArrayList<>();
                while (columns.next()) {

                    String remarks = columns.getString("REMARKS");
                    ColumnClass columnClass = new ColumnClass();
                    columnClass.setRemark(remarks);
                    columnClass.setColumnName(column_name);
                    columnClass.setType(type_name);
                    columnClass.setPropertyName(CaseFormat.LOWER_UNDERSCORE.to(CaseFormat.UPPER_CAMEL, column_name));
                    primaryKeys.first();
                    while (primaryKeys.next()) {
                        String pkName = primaryKeys.getString("COLUMN_NAME");
                        if (column_name.equals(pkName)) {
                            columnClass.setPrimary(true);
                        }
                    }
                    columnClassList.add(columnClass);
                }
                tableClass.setColumns(columnClassList);
                String path = realPath + "/" + tableClass.getPackageName().replace(".", "/");
                generate(modelTemplate, tableClass, path + "/model/");
                generate(mapperJavaTemplate, tableClass, path + "/mapper/");
                generate(mapperXmlTemplate, tableClass, path + "/mapper/");
                generate(serviceTemplate, tableClass, path + "/service/");
                generate(controllerTemplate, tableClass, path + "/controller/");
            }
            return RespBean.ok("代码已生成", realPath);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return RespBean.error("代码生成失败");
    }

    private void generate(Template template, TableClass tableClass, String path) throws IOException, TemplateException {
        File folder = new File(path);

        }
        String fileName = path + "/" + tableClass.getModelName() + template.getName().replace(".ftl", "").replace("Model", "");
        FileOutputStream fos = new FileOutputStream(fileName);
        OutputStreamWriter out = new OutputStreamWriter(fos);
        template.process(tableClass,out);
        fos.close();
        out.close();
    }
}
