spring-data-redis2.0以上配置redis连接
1.所需的maven依赖
<dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>2.0.0.RELEASE</version> </dependency> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-xxx</artifactId> </dependency>
此处需要注意的是spring-data-redis2.0以上版本所需的jedis版本为2.9.0 目前最新的版本也为2.9.0 否则会报ClassNotFoundException或者NoSuchMethodError等异常
此外如果想查看工程用的包所依赖的包的版本可以去http://mvnrepository.com/ 网上输入对应的包如spring-data-redis
点击后会罗列出maven仓库里所包含的版本 点击当前使用的版本如案例中的2.0.0 往下翻则会展示出所选包依赖的包
这儿就会指明依赖jedis的包且最低版本为2.9.0
2.配置redis.properties
redis.host = 172.25.12.123
redis.port = 6379
redis.auth = admin
redis.maxTotal = 100
redis.maxIdle = 20
redis.maxWaitMillis = 10000
redis.testOnBorrow = true
redis.testOnReturn = true
redis.dbIndex = 3
3.配置spring-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: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 "> <!--引入配置文件--> <context:property-placeholder location="redis.properties" ignore-unresolvable="true"></context:property-placeholder> <!--设置jedisPool链接池的配置--> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxTotal" value="${redis.maxTotal}"/> <property name="maxIdle" value="${redis.maxIdle}"/> <property name="maxWaitMillis" value="${redis.maxWaitMillis}"/> <property name="testOnBorrow" value="${redis.testOnBorrow}"/> <property name="testOnReturn" value="${redis.testOnReturn}"/> </bean> <!--redis链接密码--> <bean id="redisPassword" class="org.springframework.data.redis.connection.RedisPassword"> <constructor-arg name="thePassword" value="${redis.auth}"></constructor-arg> </bean> <!--spring-data-redis2.0以上的配置--> <bean id="redisStandaloneConfiguration" class="org.springframework.data.redis.connection.RedisStandaloneConfiguration"> <property name="hostName" value="${redis.host}"/> <property name="port" value="${redis.port}"/> <property name="password" ref="redisPassword" /> <property name="database" value="${redis.dbIndex}"/> </bean> <!--配置jedis链接工厂 spring-data-redis2.0中 建议改为构造器传入一个RedisStandaloneConfiguration 单机 RedisSentinelConfiguration 主从复制 RedisClusterConfiguration 集群--> <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"> <!--注销掉的部分为spring-data-redis2.0以下的版本配置的方式--> <!-- <property name="hostName" value="${redis.host}"/> <property name="port" value="${redis.port}"/> <property name="poolConfig" ref="jedisPoolConfig"/> <property name="password" value="${redis.auth}" /> <property name="database" value="${redis.dbIndex}"/>--> <!--spring-data-redis2.0以上建议获取的方式--> <constructor-arg name="standaloneConfig" ref="redisStandaloneConfiguration"></constructor-arg> </bean> <!--手动设置 key 与 value的序列化方式--> <bean id="keySerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer"/> <bean id="valueSerializer" class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/> <!--配置jedis模板 --> <bean id = "redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"> <property name="connectionFactory" ref="jedisConnectionFactory" /> <property name="keySerializer" ref="keySerializer" /> <property name="valueSerializer" ref="valueSerializer" /> <property name="hashKeySerializer" ref="keySerializer" /> <property name="hashValueSerializer" ref="valueSerializer" /> </bean> <!--也可以StringRedisTemplate 专注于String的操作 --> <bean id="stringRedisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate"> <!--<property name="connectionFactory" ref="jedisConnectionFactory"></property>--> <!--在StringRedisTemplate与redisTemplate不同,可以直接造构造器中传入ConnectionFactory--> <constructor-arg name="connectionFactory" ref="jedisConnectionFactory"></constructor-arg> <property name="keySerializer" ref="keySerializer" /> <property name="valueSerializer" ref="valueSerializer" /> <property name="hashKeySerializer" ref="keySerializer" /> <property name="hashValueSerializer" ref="valueSerializer" /> </bean> </beans>
上面需要注意一点的是
在spring-data-redis2.0以上的版本中在配置密码的时候不能像老版本直接设置密码值,需要注入一个RedisPassword的bean 在RedisPassword的构造方法中设置密码
3.最后进行测试测试
package com.springactul.splx.nosql.redis; 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.data.redis.core.StringRedisTemplate; import org.springframework.data.redis.core.ValueOperations; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; /** * Created by zhoum on 2018-06-22. */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath*:spring-*.xml"}) public class RedisTest { @Autowired private RedisTemplate redisTemplate; @Autowired private StringRedisTemplate stringRedisTemplate; @Test public void test1(){ ValueOperations valueOperations = redisTemplate.opsForValue(); valueOperations.set("first","hellow word"); System.out.println(valueOperations.get("first")); } @Test public void test2(){ ValueOperations<String, String> stringStringValueOperations = stringRedisTemplate.opsForValue(); stringStringValueOperations.set("secound","hello everyone"); System.out.println(stringStringValueOperations.get("secound")); } }
注意:在本篇博客中只讲了RedisStandalongConfiguration的配置方式 ,并且测试本着以能连通redis的目的进行非常简单的测试,如果想要了解更详细的使用或者配置
