基于SpringBoot集成测试远程连接Redis服务的教程详解

前期准备

Linux虚拟机或者租用的云服务器：sudo安装redis，或者docker加载redis镜像。后者需要使用docker启用redis容器。

配置好redis.conf文件。注意：一定要注释 # bind 127.0.0.1 其他详细配置可参考我另一篇文章，不过能想到集成测试redis，配置文件应该已经配置好了。

/sbin/iptables -I INPUT -p tcp --dport 6379 -j ACCEPT 开放6379端口

初始化SpringBoot项目使用Spring Initializr 初始化一个SpringBoot项目，可以勾选NoSQL下这两项，或者后面自行添加pom依赖。（当然也可以初始化一个maven项目来测试）

添加jedis依赖

<!--导入jedis依赖-->
<dependency>
 <groupId>redis.clients</groupId>
 <artifactId>jedis</artifactId>
 <version>3.2.0</version>
</dependency>

编写简易的单元测试程序

可使用ifconfig 或者 ip addr 查询服务器的ip地址

/**
* host： 虚拟机或远程服务器的ip地址
* port： redis.conf中配置的服务端口号
*/
@Test
void TestPing() {
 Jedis jedis = new Jedis("192.168.137.132",6379);
 System.out.println("TestPing >>>>>>>>>>>>> "+jedis.ping());
}

测试结果：

测试五大基本数据类型

测试过程中，有些数据防止重复插入，部分测试用例使用了del命令。

  • 五大基本数据类型：字符串，列表，哈希，集合，有序集合
  • 每次单元测试都需进行远程连接，故做以下处理：
@SpringBootTest
class JedisDemoApplicationTests {
 
 // 此处配置连接
 Jedis jedis = new Jedis("192.168.137.132",6379);

 @Test
 void contextLoads() {
 }
 
 // 此处进行单元测试
}

Key键

测试用例：

@Test
void KeyTest() {
 System.out.println(jedis.keys("*"));
 System.out.println(jedis.keys("*").getClass());
}

测试结果：

  •  [list01, customer, set01, username]
  • class java.util.HashSet

String字符串

测试用例：

@Test
void StringTest() {
 System.out.println("测试set >>> "+jedis.set("name", "kris"));
 System.out.println("测试get >>> "+jedis.get("name"));
 System.out.println(jedis.get("name").getClass());

 System.out.println("\n测试append >>> "+jedis.append("name", " ^v^"));
 System.out.println("测试strlen >>> "+jedis.strlen("name"));
 System.out.println("测试get >>> "+jedis.get("name"));

 System.out.println("\n测试mset >>> "+jedis.mset(
  "username", "kris",
  "age", "18",
  "sex","男"));
 System.out.println("测试mget >>> "+jedis.mget("username", "age", "sex"));

 System.out.println("\n测试incr >>> "+jedis.incr("age"));
 System.out.println("测试incrBy >>> "+jedis.incrBy("age",3));
 System.out.println("测试decr >>> "+jedis.decr("age"));
 System.out.println("测试decrBy >>> "+jedis.decrBy("age", 3));
}

测试结果：

  • 测试set >>> OK
  • 测试get >>> kris
  • class java.lang.String
  • 测试append >>> 8
  • 测试strlen >>> 8
  • 测试get >>> kris ^v^
  • 测试mset >>> OK
  • 测试mget >>> [kris, 18, 男]
  • 测试incr >>> 19
  • 测试incrBy >>> 22
  • 测试decr >>> 21
  • 测试decrBy >>> 18

List列表

测试用例：

@Test
void ListTest() {
 System.out.println("测试rpush >>> "+jedis.rpush("list01", "I", "love", "redis", "!"));
 System.out.println("测试lpush >>> "+jedis.lpush("list01", "hello"));
 System.out.println("测试lrange >>> "+jedis.lrange("list01", 0, -1));
 System.out.println(jedis.lrange("list01", 0, -1).getClass());

 System.out.println("\n测试lpop >>> "+jedis.lpop("list01"));
 System.out.println("测试rpop >>> "+jedis.rpop("list01"));
 System.out.println("测试lrange >>> "+jedis.lrange("list01", 0, -1));

 System.out.println("\n测试lset >>> "+jedis.lset("list01", 0, "We"));
 System.out.println("测试lrange >>> "+jedis.lrange("list01", 0, -1));

 System.out.println("\n测试 linsert >>> "+jedis.linsert("list01", ListPosition.AFTER,
               "redis", "!"));
 System.out.println("测试lrange >>> "+jedis.lrange("list01", 0, -1));

 jedis.del("list01");
}

测试结果：

  • 测试rpush >>> 4
  • 测试lpush >>> 5
  • 测试lrange >>> [hello, I, love, redis, !]
  • class java.util.ArrayList
  • 测试lpop >>> hello
  • 测试rpop >>> !
  • 测试lrange >>> [I, love, redis]
  • 测试lset >>> OK
  • 测试lrange >>> [We, love, redis]
  • 测试 linsert >>> 4
  • 测试lrange >>> [We, love, redis, !]
  • Hash哈希

测试用例：

@Test
void HashTest() {
 Map<String, String> customer = new HashMap<>();
 customer.put("username", "kris");
 customer.put("password", "123456");
 customer.put("email", "kris@163.com");

 System.out.println("测试hset >>> "+jedis.hset("customer", customer));
 System.out.println("测试hget >>> "+jedis.hget("customer", "email"));
 System.out.println("测试getAll >>> "+jedis.hgetAll("customer"));
 System.out.println(jedis.hgetAll("customer").getClass());
}

测试结果：

测试hset >>> 0
测试hget >>> kris@163.com
测试getAll >>> {name=kris, email=kris@163.com, password=123456, username=kris}
class java.util.HashMap

Set集合

测试用例：

@Test
void SetTest() {
 System.out.println("测试sadd >>> "+jedis.sadd("names", "louis", "kris", "Jerry", "Jackson"));
 System.out.println("测试smembers >>> "+jedis.smembers("names"));
 System.out.println("测试scard >>> "+jedis.scard("names"));
 System.out.println(jedis.smembers("names").getClass());

 System.out.println("\n测试srandmember >>> "+jedis.srandmember("names", 3));
 System.out.println("测试srandmember >>> "+jedis.srandmember("names", 3));

 System.out.println("\n测试spop >>> "+jedis.spop("names", 2));
 System.out.println("测试smembers >>> "+jedis.smembers("names"));

 System.out.println("\n测试sadd >>> "+jedis.sadd("names0", "Jack", "louis", "kris"));
 System.out.println("测试sunion >>> "+jedis.sunion("names", "names0"));
 System.out.println("测试sdiff >>> "+jedis.sdiff("names", "names0"));
 System.out.println("测试sinter >>> "+jedis.sinter("names", "names0"));
 System.out.println("测试smembers >>> "+jedis.smembers("names"));
 System.out.println("测试smembers >>> "+jedis.smembers("names0"));

 jedis.del("names", "names0");
}

测试结果：

测试sadd >>> 4
测试smembers >>> [kris, Jerry, Jackson, louis]
测试scard >>> 4
class redis.clients.jedis.BinaryJedis$SetFromList

测试srandmember >>> [kris, Jerry, Jackson]
测试srandmember >>> [Jerry, louis, Jackson]

测试spop >>> [Jerry, kris]
测试smembers >>> [Jackson, louis]

测试sadd >>> 3
测试sunion >>> [Jack, kris, louis, Jackson]
测试sdiff >>> [Jackson]
测试sinter >>> [louis]
测试smembers >>> [Jackson, louis]
测试smembers >>> [kris, Jack, louis]

ZSet有序集合

测试用例：

@Test
void SortSetTest() {
 Map<String, Double> score = new HashMap<>();
 score.put("钻石", 1000.0);
 score.put("王者", 2000.0); // 无序
 score.put("星耀", 1500.0);
 score.put("荣耀", 2500.0);

 System.out.println("测试zadd >>> "+jedis.zadd("score", score));
 System.out.println("测试zrangeByScore >>> "+jedis.zrangeByScore("score", 1500,2500));
 System.out.println("测试zrange >>> "+jedis.zrange("score", 0,-1));
 System.out.println("测试zrevrange >>> "+jedis.zrevrange("score", 0,-1));
 System.out.println(jedis.smembers("names").getClass());
 
 jedis.del("score");
}

测试结果：

测试zadd >>> 4
测试zrangeByScore >>> [星耀, 王者, 荣耀]
测试zrange >>> [钻石, 星耀, 王者, 荣耀]
测试zrevrange >>> [荣耀, 王者, 星耀, 钻石]
class redis.clients.jedis.BinaryJedis$SetFromList
