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");
}
