Spring Data Redis 小demo

一、简介

Spring-data-redis是spring大家族的一部分，提供了在srping应用中通过简单的配置访问redis服务，对reids底层开发包(Jedis, JRedis, and RJC)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，并对spring 3.1 cache进行了实现。

spring-data-redis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
ValueOperations：简单K-V操作
SetOperations：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

二、添加依赖

<!-- 缓存 -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.8.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>1.7.2.RELEASE</version>
        </dependency>

三、配置文件

a、src/main/resources下创建properties文件夹，建立redis-config.properties

# Redis settings
# server IP
redis.host=192.168.200.128
# server port
redis.port=6379
# server pass
redis.pass=
# use dbIndex
redis.database=0
# \u63A7\u5236\u4E00\u4E2Apool\u6700\u591A\u6709\u591A\u5C11\u4E2A\u72B6\u6001\u4E3Aidle(\u7A7A\u95F2\u7684)\u7684jedis\u5B9E\u4F8B
redis.maxIdle=300
# \u8868\u793A\u5F53borrow(\u5F15\u5165)\u4E00\u4E2Ajedis\u5B9E\u4F8B\u65F6\uFF0C\u6700\u5927\u7684\u7B49\u5F85\u65F6\u95F4\uFF0C\u5982\u679C\u8D85\u8FC7\u7B49\u5F85\u65F6\u95F4(\u6BEB\u79D2)\uFF0C\u5219\u76F4\u63A5\u629B\u51FAJedisConnectionException\uFF1B
redis.maxWait=3000
# \u5728borrow\u4E00\u4E2Ajedis\u5B9E\u4F8B\u65F6\uFF0C\u662F\u5426\u63D0\u524D\u8FDB\u884Cvalidate\u64CD\u4F5C\uFF1B\u5982\u679C\u4E3Atrue\uFF0C\u5219\u5F97\u5230\u7684jedis\u5B9E\u4F8B\u5747\u662F\u53EF\u7528\u7684
redis.testOnBorrow=true

b、在src/main/resources下创建spring文件夹，创建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/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">



   <!-- 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>

四、测试代码

a、值类型操作

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
public class TestValue {

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void setValue(){
        redisTemplate.boundValueOps("name").set("offcn");
    }

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

    @Test
    public void deleteValue(){
        redisTemplate.delete("name");
    }

}

b、set类型操作

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
public class TestSet {

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void setValue(){
        redisTemplate.boundSetOps("nameset").add("曹操");
        redisTemplate.boundSetOps("nameset").add("刘备");
        redisTemplate.boundSetOps("nameset").add("孙权");
    }

    @Test
    public void getValue(){
        Set set = redisTemplate.boundSetOps("nameset").members();
        System.out.println(set);
    }

    @Test
    public void removeValue(){
        redisTemplate.boundSetOps("nameset").remove("孙权");
    }

    @Test
    public void delete(){
        redisTemplate.delete("nameset");
    }

}

c、list类型操作

右压栈：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
public class TestList {

    @Autowired
    private RedisTemplate redisTemplate;

    /*
     * 右压栈 : 后添加的元素排在后边
     */
    @Test
    public void testSetValue1(){
        redisTemplate.boundListOps("namelist1").rightPush("刘备");
        redisTemplate.boundListOps("namelist1").rightPush("关羽");
        redisTemplate.boundListOps("namelist1").rightPush("张飞");
    }

    /**
     * 显示右压栈的值
     */
    @Test
    public void testGetValue1(){
        List list = redisTemplate.boundListOps("namelist1").range(0, 10);
        System.out.println(list);
    }

    @Test
    public void delete(){
        redisTemplate.delete("namelist1");
    }

}

左压栈：

    /**
     * 左压栈
     */
    @Test
    public void testSetValue2(){
        redisTemplate.boundListOps("namelist2").leftPush("刘备");
        redisTemplate.boundListOps("namelist2").leftPush("关羽");
        redisTemplate.boundListOps("namelist2").leftPush("张飞");
    }

    /**
     * 显示左压栈的值
     */
    @Test
    public void testGetValue2(){
        List list = redisTemplate.boundListOps("namelist2").range(0, 10);
        System.out.println(list);
    }

d、hash类型

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
public class TestHash {

    @Autowired
    private RedisTemplate redisTemplate;

    /**
     * 存值
     */
    @Test
    public void testSetValue(){
        redisTemplate.boundHashOps("namehash").put("a", "唐僧");
        redisTemplate.boundHashOps("namehash").put("b", "悟空");
        redisTemplate.boundHashOps("namehash").put("c", "八戒");
        redisTemplate.boundHashOps("namehash").put("d", "沙僧");

    }

操作
