场景


通过以上教程将Redis的环境搭建起来后，使用SpringDataRedis在Java中对Redis进行操作。

SpringDataRedis

SpringDataRedis是spring大家族中的一部分,提供了在spring应用中通过简单的配置访问redis服务,对redis底层开发包(Jedis,JRedis,andRJC)进行了高度封装,RedisTemplate提供了redis各种操作,异常处理及序列化,支持发布订阅

SpringDataRedis针对Jedis提供了如下功能:

1.连接池自动管理,提供了一个高度封装的RedisTemplate类

2.针对Jedis客户端中大量api进行了归类封装,将同一类型操作封装为operation接口

ValueIoerations:简单K-V操作

SetIOperations:set类型数据操作.

ZSetOperations:zset类型数据操作

HashOperations:针对map类型的数据操作

ListOperations:针对list类型的数据操作.

实现

打开IDEA新建project-Maven Project

然后打开pom.xml，添加spring和jedis以及junit的依赖

                </plugin>
            </plugins>
        </build>
</project>

然后在src/main/resources下创建properties文件夹,然后新建文件redis-config.properties

在此属性文件中配置redis连接的ip和端口等信息

# Redis settings
# server IP
redis.host=192.168.40.133
# server port
redis.port=6379
# server pass
redis.pass=
# use dbIndex
redis.database=0
# 最大空闲数
redis.maxIdle=300
#连接时的最大等待数
redis.maxWait=3000
#在提取一个jedis实例时，是否提前进行验证操作；如果为true，则得到的jedis实例均是可用的；
redis.testOnBorrow=true

同理再在src/main/resources下创建spring文件夹,然后新建文件applicationContext-redis.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:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:cache="http://www.springframework.org/schema/cache"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

            http://www.springframework.org/schema/context/spring-context.xsd
            http://www.springframework.org/schema/mvc
            http://www.springframework.org/schema/mvc/spring-mvc.xsd
            http://www.springframework.org/schema/cache
            http://www.springframework.org/schema/cache/spring-cache.xsd
            http://www.springframework.org/schema/mvc ">

    <context:property-placeholder location="classpath*:properties/*.properties"/>

    <!-- redis 相关配置 -->
    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxIdle" value="${redis.maxIdle}"/>
        <property name="maxWaitMillis" value="${redis.maxWait}"/>
        <property name="testOnBorrow" value="${redis.testOnBorrow}"/>
    </bean>

    <bean id="JedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
          p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:pool-config-ref="poolConfig"/>

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="JedisConnectionFactory"/>
    </bean>

</beans>

然后在src/main下新建包，包中新建类，开启Redis服务端后进行测试存取值

package com.badao.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring/applicationContext-redis.xml")
public class SpringDataRedisTest {
    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void setValue(){
        redisTemplate.boundValueOps("name").set("badao");
    }
    @Test
    public void getValue(){
        String str = (String) redisTemplate.boundValueOps("name").get();
        System.out.println(str);
    }

}

运行单元测试方法，先存值再取值结果
