Spring Data Redis 小demo
一、简介
Spring-data-redis是spring大家族的一部分，提供了在srping应用中通过简单的配置访问redis服务，对reids底层开发包(Jedis, JRedis, and RJC)进行了高度封装，RedisTemplate提供了redis各种操作、异常处理及序列化，支持发布订阅，并对spring 3.1 cache进行了实现。
spring-data-redis针对jedis提供了如下功能：
1.连接池自动管理，提供了一个高度封装的“RedisTemplate”类
2.针对jedis客户端中大量api进行了归类封装,将同一类型操作封装为operation接口
ValueOperations：简单K-V操作
SetOperations：set类型数据操作
ZSetOperations：zset类型数据操作
HashOperations：针对map类型的数据操作
ListOperations：针对list类型的数据操作
二、添加依赖
<!-- 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>
三、配置文件
a、src/main/resources下创建properties文件夹，建立redis-config.properties
# Redis settings
# server IP
redis.host=192.168.200.128
# server port
redis.port=6379
# server pass
redis.pass=
# use dbIndex
redis.database=0
# \u63A7\u5236\u4E00\u4E2Apool\u6700\u591A\u6709\u591A\u5C11\u4E2A\u72B6\u6001\u4E3Aidle(\u7A7A\u95F2\u7684)\u7684jedis\u5B9E\u4F8B
redis.maxIdle=300
# \u8868\u793A\u5F53borrow(\u5F15\u5165)\u4E00\u4E2Ajedis\u5B9E\u4F8B\u65F6\uFF0C\u6700\u5927\u7684\u7B49\u5F85\u65F6\u95F4\uFF0C\u5982\u679C\u8D85\u8FC7\u7B49\u5F85\u65F6\u95F4(\u6BEB\u79D2)\uFF0C\u5219\u76F4\u63A5\u629B\u51FAJedisConnectionException\uFF1B
redis.maxWait=3000
# \u5728borrow\u4E00\u4E2Ajedis\u5B9E\u4F8B\u65F6\uFF0C\u662F\u5426\u63D0\u524D\u8FDB\u884Cvalidate\u64CD\u4F5C\uFF1B\u5982\u679C\u4E3Atrue\uFF0C\u5219\u5F97\u5230\u7684jedis\u5B9E\u4F8B\u5747\u662F\u53EF\u7528\u7684
redis.testOnBorrow=true
b、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"> <!-- 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>
四、测试代码
a、值类型操作
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml") public class TestValue { @Autowired private RedisTemplate redisTemplate; @Test public void setValue(){ redisTemplate.boundValueOps("name").set("offcn"); } @Test public void getValue(){ String str = (String) redisTemplate.boundValueOps("name").get(); System.out.println(str); } @Test public void deleteValue(){ redisTemplate.delete("name"); } }
b、set类型操作
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml") public class TestSet { @Autowired private RedisTemplate redisTemplate; @Test public void setValue(){ redisTemplate.boundSetOps("nameset").add("曹操"); redisTemplate.boundSetOps("nameset").add("刘备"); redisTemplate.boundSetOps("nameset").add("孙权"); } @Test public void getValue(){ Set set = redisTemplate.boundSetOps("nameset").members(); System.out.println(set); } @Test public void removeValue(){ redisTemplate.boundSetOps("nameset").remove("孙权"); } @Test public void delete(){ redisTemplate.delete("nameset"); } }
c、list类型操作
右压栈：
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml") public class TestList { @Autowired private RedisTemplate redisTemplate; /* * 右压栈 : 后添加的元素排在后边 */ @Test public void testSetValue1(){ redisTemplate.boundListOps("namelist1").rightPush("刘备"); redisTemplate.boundListOps("namelist1").rightPush("关羽"); redisTemplate.boundListOps("namelist1").rightPush("张飞"); } /** * 显示右压栈的值 */ @Test public void testGetValue1(){ List list = redisTemplate.boundListOps("namelist1").range(0, 10); System.out.println(list); } @Test public void delete(){ redisTemplate.delete("namelist1"); } }
左压栈：
/** * 左压栈 */ @Test public void testSetValue2(){ redisTemplate.boundListOps("namelist2").leftPush("刘备"); redisTemplate.boundListOps("namelist2").leftPush("关羽"); redisTemplate.boundListOps("namelist2").leftPush("张飞"); } /** * 显示左压栈的值 */ @Test public void testGetValue2(){ List list = redisTemplate.boundListOps("namelist2").range(0, 10); System.out.println(list); }
d、hash类型
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations="classpath:spring/applicationContext-redis.xml") public class TestHash { @Autowired private RedisTemplate redisTemplate; /** * 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"); }
