Jedis

1.

引入依赖：

        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>

 

测试类：

public class JedisConnTest {
    //使用jedis操作String 类型
    @Test
    public void testString() {
        Jedis jedis = new Jedis("192.168.53.177", 6379);
        jedis.set("alias", "lisi");
        String result = jedis.get("alias");
        System.out.println(result);
        jedis.close();
    }

    // 使用jedis操作map类型
    @Test
    public void testMap() {
        Jedis jedis = new Jedis("192.168.53.177", 6379);
        jedis.hset("user", "name", "zhangsan");
        jedis.hset("user", "age", "12");
        String name = jedis.hget("user", "name");
        String age = jedis.hget("user", "age");
        System.out.println(name + "-" + age);
        jedis.close();
    }
    
    // 使用连接池的jedis
    @Test
    public void testJedisPool() {
        JedisPool pool = new JedisPool("192.168.53.177", 6379);
        Jedis jedis = pool.getResource();
        jedis.hset("cat","color","yellow");
        System.out.println(jedis.hget("cat", "color"));
    }
}

结果亲测有效（ 注意关闭centos防火墙）

 

 

2. 由此可见spring只需要配置bean， spring版本的：

最简版 -当然这不科学：

   
   <bean id="redis" class="redis.clients.jedis.Jedis" >
      <constructor-arg name="host" value="192.168.53.177" />
      <constructor-arg name="port" value="6379" />
   </bean>

 

连接池：

   <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
      <!-- 连接池配置 -->
      <constructor-arg name="poolConfig" ref="poolConfig" />
      <constructor-arg name="host" value="192.168.53.177" />
      <constructor-arg name="port" value="6379" />
   </bean>
   
   <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
      <!-- 最大连接数 -->
      <property name="maxTotal" value="30" />
      <!-- 最大空闲连接数 -->
      <property name="maxIdle" value="10"/>
      <!-- 连接耗尽是否阻塞 -->
      <property name="blockWhenExhausted" value="true"/>
   </bean>

测试连接池：

@Controller
public class FirstController {
    @Autowired
    JedisPool pool;

    @RequestMapping("/first")
    @ResponseBody
    public String first() {
        Jedis jedis = pool.getResource();
        jedis.set("hobby", "sleep");
        String result = jedis.get("hobby");
        System.out.println(result);
        return "ok";
    }
}
