## spring + Jedis 的方式使用缓存 ##

1.  jar 包
    
        <dependency>
           <groupId>redis.clients</groupId>
           <artifactId>jedis</artifactId>
           <version>2.8.1</version>
        </dependency>
2.  配置文件
    
    config.properties
    
        redis.host=127.0.0.1
        redis.port=6379
        redis.password=foobared
        redis.timeout=60000
        redis.database=0
        redis.pool.maxActive=300
        redis.pool.maxIdle=100
        redis.pool.maxWait=2000
    
    spring-jedis.xml
    
        <?xml version="1.0" encoding="UTF-8"?>
        <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
        
           <context:property-placeholder location="classpath:config.properties"/>
        
           <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
               <property name="maxTotal" value="${redis.pool.maxActive}" />
               <property name="maxIdle" value="${redis.pool.maxIdle}" />
               <property name="maxWaitMillis" value="${redis.pool.maxWait}" />
               <property name="testOnBorrow" value="false" />
               <property name="testOnReturn" value="false" />
           </bean>
        
           <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
               <constructor-arg name="poolConfig" ref="jedisPoolConfig" />
               <constructor-arg name="host" value="${redis.host}" />
               <constructor-arg name="port" value="${redis.port}" type="int" />
               <constructor-arg name="timeout" value="${redis.timeout}" type="int" />
               <constructor-arg name="password" value="${redis.password}" />
               <constructor-arg name="database" value="${redis.database}" type="int" />
           </bean>
        </beans>
    
    
3.  测试
    
        package com.susq.jedis;
        
        import lombok.extern.slf4j.Slf4j;
        import org.junit.Test;
        import org.junit.runner.RunWith;
        import org.springframework.beans.factory.annotation.Autowired;
        import org.springframework.test.context.ContextConfiguration;
        import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
        import redis.clients.jedis.Jedis;
        import redis.clients.jedis.JedisPool;
        
        /** * @author susq * @since 2018-05-04-10:17 */
        @Slf4j
        @RunWith(SpringJUnit4ClassRunner.class)
        @ContextConfiguration(value = "classpath:spring-jedis.xml")
        public class JedisTest { 
        
           @Autowired
           private JedisPool jedisPool;
        
           @Test
           public void setTest() {
               Jedis jedis = jedisPool.getResource();
               String codeReply = jedis.set("key2","hello jedis one");
               jedis.close();
               log.info(codeReply);
           }
        
           @Test
           public void getTest() {
               Jedis jedis = jedisPool.getResource();
               String value = jedis.get("key2");
               log.info(value);
           }
        
           @Test
           public void del() {
               Jedis jedis = jedisPool.getResource();
               jedis.set("key2","hello jedis one");
               log.info(jedis.get("key2"));
               jedis.del("key2");
               log.info(jedis.get("key2"));
           }
        }
