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

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70][]

依次输入坐标，建成后目录

然后打开pom.xml，添加spring和jedis以及junit的依赖

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

            </dependency>
        </dependencies>
            <build>
                <plugins>
                    
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-compiler-plugin</artifactId>
                        <version>3.2</version>
                        <configuration>
                            <source>1.7</source>
                            <target>1.7</target>
                            <encoding>UTF-8</encoding>
                        </configuration>
                    </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

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 3][]

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

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 4][]

<?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/beans/spring-beans.xsd
                http://www.springframework.org/schema/context
                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"/>
    
        
        <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
