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"));
      }
   }
