一、Redis安装

已经安装好redis的可以直接进入下一步，没有的可以先进行安装：Linux（CentOS 7）Redis 安装

二、pom依赖:

		<dependency>
			<groupId>org.springframework.data</groupId>
			<artifactId>spring-data-redis</artifactId>
			<version>1.5.1.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
			<version>2.6.1</version>
		</dependency>

三、spring配置

在resources目录下新建一个redis.properties：

#redis setting
redis.hostName =192.168.240.131
redis.port=6379
redis.timeout=15000
redis.usePool=true
redis.password=buildmavenweb

#jedis setting
jedis.maxIdle=6
jedis.minEvictableIdleTimeMillis=300000
jedis.numTestsPerEvictionRun=3
jedis.timeBetweenEvictionRunsMillis=60000

	   default-lazy-init="true">

	<context:component-scan base-package="com.spring.demo.redis" />

	<!-- 引入redis配置文件 -->
	<context:property-placeholder location="classpath:redis.properties" />

	<!-- 连接池配置 -->
	<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
		<!-- 连接池中最大空闲的连接数 -->
		<property name="maxIdle" value="${jedis.maxIdle}"></property>
		<!-- 连接空闲的最小时间，达到此值后空闲连接将可能会被移除。负值(-1)表示不移除. -->
		<property name="minEvictableIdleTimeMillis" value="${jedis.minEvictableIdleTimeMillis}"></property>
		<!-- 对于“空闲链接”检测线程而言，每次检测的链接资源的个数。默认为3 -->
		<property name="numTestsPerEvictionRun" value="${jedis.numTestsPerEvictionRun}"></property>
		<!-- “空闲链接”检测线程，检测的周期，毫秒数。如果为负值，表示不运行“检测线程”。默认为-1. -->
		<property name="timeBetweenEvictionRunsMillis" value="${jedis.timeBetweenEvictionRunsMillis}"></property>
	</bean>

	<!-- Spring提供的Redis连接工厂 -->
	<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy">
		<!-- 连接池配置 -->
		<property name="poolConfig" ref="jedisPoolConfig"></property>
		<!-- Redis服务主机 -->
		<property name="hostName" value="${redis.hostName}"></property>
		<!-- Redis服务端口号 -->
		<property name="port" value="${redis.port}"></property>
		<!-- 连超时设置 -->
		<property name="timeout" value="${redis.timeout}"></property>
		<!-- 是否使用连接池 -->
		<property name="usePool" value="${redis.usePool}"></property>
		<!-- Redis服务连接密码 -->
		<property name="password" value="${redis.password}"></property>
	</bean>

	<!-- Spring提供的访问Redis类 -->
	<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
		<!-- Redis连接工厂 -->
		<property name="connectionFactory" ref="jedisConnectionFactory"></property>
		<property name="keySerializer">
			<bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
		</property>
		<!-- JdkSerializationRedisSerializer支持对所有实现了Serializable的类进行序列化 -->
		<property name="valueSerializer">
			<bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>
		</property>
	</bean>
</beans>

PS: 下面这段内容取自：http://shift-alt-ctrl.iteye.com/blog/1887370

 spring-data-redis提供了多种serializer策略，这对使用jedis的开发者而言，实在是非常便捷。sdr提供了4种内置的serializer：

四、web.xml中

	<!-- 加载配置文件 -->
	<!--contextConfigLocation在 ContextLoaderListener类中的默认值是 /WEB-INF/applicationContext.xml -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			classpath:/spring-*.xml
		</param-value>
	</context-param>

五、java代码中使用

新建一个RedisUtils.class,用来专门处理redis的相关操作：

package com.spring.demo.redis;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

/**
 * Created by ehsy_it on 2016/8/7.
 */
@Component
public class RedisUtils {

    @Autowired
    private RedisTemplate<String,Object> redisTemplate;

    /**
     * 得到指定key值的value
     * @param key
     */
    public Object get(String key){
        return redisTemplate.boundValueOps(key).get();
    }

    /**
     * 保存指定key值的value
     * @param key
     * @param value
     */
    public void set(String key, Object value){
        redisTemplate.boundValueOps(key).set(value);
    }

    /**
     * 删除指定key的value
     * @param key
     */
    public void del(String key){
        redisTemplate.delete(key);
    }
}

六、测试

package com.spring.demo.redis;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by ehsy_it on 2016/8/7.
 */
public class RedisMain {

    public static void main(String[] args) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("/spring-redis.xml");
        RedisUtils redisUtils = (RedisUtils) ctx.getBean("redisUtils");
        redisUtils.set("china","瓷器");
        List<String> list = new ArrayList<String>();
        list.add("a");
        list.add("b");
        list.add("c");
        redisUtils.set("list", list);
        System.out.println("china=" + redisUtils.get("china"));
        System.out.println("list[1]=" + ((List)redisUtils.get("list")).get(1));
    }
}
