SpringDataRedis入门Demo

步骤：

约定>配置>代码

在pom.xml中导入依赖(redis和jedis以及其余所需的依赖) > 配置相关配置文件（redis-config.properties 和applicationContext-redis.xml） >  进行代码的测试

1：准备工做

新建一台虚拟机安装Redis环境（具体安装步骤参见资源文件（资源\Redis\Redis安装配置.docx））

（1）构建Maven工程  SpringDataRedisDemo

（2）引入Spring相关依赖、引入JUnit依赖   

<properties>
   <spring.version>4.2.4.RELEASE</spring.version>
   <junit.version>4.12</junit.version>
</properties>
  <dependencies>
    <!-- Spring -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>    
        <version>${spring.version}</version>    
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>    
        <version>${spring.version}</version>    
    </dependency>    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>    
        <version>${spring.version}</version>    
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>    
        <version>${spring.version}</version>    
    </dependency>    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>    
        <version>${spring.version}</version>    
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>    
        <version>${spring.version}</version>    
    </dependency>    
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>${junit.version}</version>
    </dependency>
  </dependencies>

（3）引入Jedis和SpringDataRedis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>    

（4）在src/main/resources下建立properties文件夹，创建redis-config.properties 

redis.host=127.0.0.1 redis.port=6379 redis.pass= redis.database=0 redis.maxIdle=300 redis.maxWait=3000 redis.testOnBorrow=true 

（5）在src/main/resources下建立spring文件夹 ，建立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" 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*: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>

maxIdle ：最大空闲数

maxWaitMillis:链接时的最大等待毫秒数

testOnBorrow：在提取一个jedis实例时，是否提早进行验证操做；若是为true，则获得的jedis实例均是可用的；

2：Demo练习

1：值类型操做

不要在测试类上添加RunWith和ContextConfiguration注解

@ContextConfiguration Spring整合JUnit4测试时，使用注解引入多个配置文件，多个之间用逗号隔开

@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml") public class TestValue { @Autowired private RedisTemplate redisTemplate;
　　 //添加值 @Test public void setValue(){ redisTemplate.boundValueOps("name").set("youjiuye"); } 
　　 //取值 @Test public void getValue(){ String str = (String) redisTemplate.boundValueOps("name").get(); System.out.println(str); } 
　　 //删除值 @Test public void deleteValue(){ redisTemplate.delete("name");; } }

2：Set类型操做

@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml") public class TestSet { @Autowired private RedisTemplate redisTemplate; //存入值 @Test public void setValue(){ redisTemplate.boundSetOps("nameset").add("曹操"); redisTemplate.boundSetOps("nameset").add("刘备"); redisTemplate.boundSetOps("nameset").add("孙权"); } //提取值 @Test public void getValue(){ Set members = redisTemplate.boundSetOps("nameset").members(); System.out.println(members); } //删除集合中的某一个值 @Test public void deleteValue(){ redisTemplate.boundSetOps("nameset").remove("孙权"); } 　　 //删除整个集合 @Test public void deleteAllValue(){ redisTemplate.delete("nameset"); } }

3：List类型操做

    /** * 右压栈：后添加的对象排在后边 */ @Test public void testSetValue1(){ redisTemplate.boundListOps("namelist1").rightPush("刘备"); redisTemplate.boundListOps("namelist1").rightPush("关羽"); redisTemplate.boundListOps("namelist1").rightPush("张飞"); } /** * 显示右压栈集合 */ @Test public void testGetValue1(){ List list = redisTemplate.boundListOps("namelist1").range(0, 10); System.out.println(list); }

    /** * 左压栈：后添加的对象排在前边 */ @Test public void testSetValue2(){ redisTemplate.boundListOps("namelist2").leftPush("刘备"); redisTemplate.boundListOps("namelist2").leftPush("关羽"); redisTemplate.boundListOps("namelist2").leftPush("张飞"); } /** * 显示左压栈集合 */ @Test public void testGetValue2(){ List list = redisTemplate.boundListOps("namelist2").range(0, 10); System.out.println(list); }

    /** * 查询集合某个元素 */ @Test public void testSearchByIndex(){ String s = (String) redisTemplate.boundListOps("namelist1").index(1); System.out.println(s); }

    /** * 移除集合某个元素 */ @Test public void testRemoveByIndex(){ redisTemplate.boundListOps("namelist1").remove(1, "关羽"); }

4：Hash类型操做

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"); }

提取全部的key

 @Test public void testGetKeys(){ Set s = redisTemplate.boundHashOps("namehash").keys(); System.out.println(s); }

提取全部的值

 @Test public void testGetValues(){ List values = redisTemplate.boundHashOps("namehash").values(); System.out.println(values); }

根据key提取值

 @Test public void testGetValues(){ List values = redisTemplate.boundHashOps("namehash").values(); System.out.println(values); }

根据key移除值

 @Test public void testRemoveValueByKey(){ redisTemplate.boundHashOps("namehash").delete("c"); }
