步骤:

约定>配置>代码

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

1:准备工作

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JedisSpringDataRedis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)src/main/resources下创建properties文件夹,建立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"
    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:连接时的最大等待毫秒数

testOnBorrow: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;

2:Demo练习

1:值类型操作

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类型操作

@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类型操作

    /**
     * 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类型操作

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");
    }

提取所有的key

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

提取所有的值

    @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");
    }
