通过以上教程将Redis的环境搭建起来后,使用SpringDataRedis在Java中对Redis进行操作。
SpringDataRedis
SpringDataRedis是spring大家族中的一部分,提供了在spring应用中通过简单的配置访问redis服务,对redis底层开发包(Jedis,JRedis,andRJC)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
SpringDataRedis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
ValueIoerations:简单K-V操作
SetIOperations: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.
实现
打开IDEA新建project-Maven Project
依次输入坐标,建成后目录
然后打开pom.xml,添加spring和jedis以及junit的依赖
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.badao.redis</groupId> <artifactId>springDataRedis</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.2.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.2.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.2.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.2.4.RELEASE</version> </dependency> <!-- 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> </dependencies> <build> <plugins> <!-- java编译插件 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </build> </project>
然后在src/main/resources下创建properties文件夹,然后新建文件redis-config.properties
在此属性文件中配置redis连接的ip和端口等信息
# Redis settings # server IP redis.host=192.168.40.133 # server port redis.port=6379 # server pass redis.pass= # use dbIndex redis.database=0 # 最大空闲数 redis.maxIdle=300 #连接时的最大等待数 redis.maxWait=3000 #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; redis.testOnBorrow=true
同理再在src/main/resources下创建spring文件夹,然后新建文件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 http://www.springframework.org/schema/mvc "> <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>
然后在src/main下新建包,包中新建类,开启Redis服务端后进行测试存取值
package com.badao.test; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:spring/applicationContext-redis.xml") public class SpringDataRedisTest { @Autowired private RedisTemplate redisTemplate; @Test public void setValue(){ redisTemplate.boundValueOps("name").set("badao"); } @Test public void getValue(){ String str = (String) redisTemplate.boundValueOps("name").get(); System.out.println(str); } }
运行单元测试方法,先存值再取值结果
