spring-data-redis
(1) 创建工程,引入相关依赖
<!-- redis缓存 --> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> </dependency> <!-- spring与redis整合 --> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> </dependency>
(2) 编写配置文件和属性文件
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"> <!-- 加载properties配置文件 --> <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="${redis.testOnBorrow}" /> </bean> <!-- spring管理redis的连接工厂 --> <bean id="JedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}" p:pool-config-ref="poolConfig" /> <!-- 配置springRedis模板 --> <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="JedisConnectionFactory" /> </bean> </beans>
redis-config.properties
# Redis settings # server IP redis.host=127.0.0.1 # server port redis.port=6379 # server pass redis.pass= # use dbIndex redis.database=0 # 控制一个pool最多有多少个状态为idle(空闲的)的jedis实例 redis.maxIdle=300 # 表示当borrow(引入)一个jedis实例时,最大的等待时间,如果超过等待时间(毫秒),则直接抛出JedisConnectionException; redis.maxWait=3000 # 在borrow一个jedis实例时,是否提前进行validate操作;如果为true,则得到的jedis实例均是可用的 redis.testOnBorrow=true
(3) 测试
1) 引入相关依赖
2) 编写类,注入redisTemplate
3) 使用redisTemplate操作redis CRUD
附:redisTemplate各种数据类型操作
(1) 值类型
redisTemplate.boundValueOps("name").set("value");
String str = (String) redisTemplate.boundValueOps("name").get();
redisTemplate.delete("name");
(2) Set类型
redisTemplate.boundSetOps("nameset").add("value1");
redisTemplate.boundSetOps("nameset").add("value2");
Set members = redisTemplate.boundSetOps("nameset").members();
redisTemplate.boundSetOps("nameset").remove("value1");
redisTemplate.delete("nameset");
(3) List类型
redisTemplate.boundListOps("namelist1").rightPush("listValue1");
redisTemplate.boundListOps("namelist1").rightPush("listValue2");// 右压栈:["listValue1", "listValue2"]
List list = redisTemplate.boundListOps("namelist1").range(0, 10);// 无法定义刚好获取整个集合,只能定义足够大的数来获取
redisTemplate.boundListOps("namelist2").leftPush("listValue3");// 左压栈:["listValue3", "listValue1", "listValue2"]
String s = (String) redisTemplate.boundListOps("namelist1").index(1);// 根据索引移除元素
redisTemplate.boundListOps("namelist1").remove(1, "listValue2");// 移除某个元素,如果有多个相同元素,只移除一个
(4) Hash类型
redisTemplate.boundHashOps("namehash").put("a", "value1");
redisTemplate.boundHashOps("namehash").put("b", "value2");
Set s = redisTemplate.boundHashOps("namehash").keys();// 获取所有key
List values = redisTemplate.boundHashOps("namehash").values();// 获取所有值
Object object = redisTemplate.boundHashOps("namehash").get("b");// 根据key取值
redisTemplate.boundHashOps("namehash").delete("c");// 根据key移除值
