一、引入依赖
<!-- 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>
二、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
三、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">
<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>
maxWaitMillis:连接时的最大等待毫秒数
maxIdle :最大空闲数
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;
四、值类型操作
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
publicclass TestValue {
@Autowired
private RedisTemplate redisTemplate;
@Test
publi cvoid setValue(){
redisTemplate.boundValueOps("name").set("itcast");
}
@Test
public void getValue(){
String str = (String) redisTemplate.boundValueOps("name").get();
System.out.println(str);
}
@Test
publi cvoid deleteValue(){
redisTemplate.delete("name");;
}
}
五、 Set类型操作
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml")
publicclass 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(){
Setmembers = 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");
}
}
六、 List类型操作
创建测试类TestList
(1)右压栈
/**
* 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(){
Listlist = redisTemplate.boundListOps("namelist1").range(0, 10);
System.out.println(list);
}
运行结果:
[刘备, 关羽, 张飞]
(2)左压栈
/**
* 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(){
Listlist = redisTemplate.boundListOps("namelist2").range(0, 10);
System.out.println(list);
}
运行结果:
[张飞, 关羽, 刘备]
(3)根据索引查询元素
/**
* 查询集合某个元素
*/
@Test
public void testSearchByIndex(){
String s = (String) redisTemplate.boundListOps("namelist1").index(1);
System.out.println(s);
}
(4)移除某个元素的值
/**
* 移除集合某个元素
*/
@Test
public void testRemoveByIndex(){
redisTemplate.boundListOps("namelist1").remove(1, "关羽");
}
七、Hash类型操作
创建测试类TestHash
(1)存入值
@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");
}
(2)提取所有的KEY
@Test
public void testGetKeys(){
Sets = redisTemplate.boundHashOps("namehash").keys();
System.out.println(s);
}
运行结果:
[a, b, c, d]
(3)提取所有的值
@Test
public void testGetValues(){
Listvalues = redisTemplate.boundHashOps("namehash").values();
System.out.println(values);
}
运行结果:
[唐僧, 悟空, 八戒, 沙僧]
(4)根据KEY提取值
@Test
publi cvoid testGetValueByKey(){
Object object = redisTemplate.boundHashOps("namehash").get("b");
System.out.println(object);
}
运行结果:
悟空
(5)根据KEY移除值
@Test
public void testRemoveValueByKey(){
redisTemplate.boundHashOps("namehash").delete("c");
}
运行后再次查看集合内容:
[唐僧, 悟空, 沙僧]
