SSM 框架集成redis

1.添加maven依赖:(注意:spring-data-redis包的版本要与spring的版本一致哦!)

<!-- 导入redis包 -->
<!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-redis -->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.8.4.RELEASE</version>
</dependency>

<!-- https://mvnrepository.com/artifact/redis.clients/jedis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>

2.redis.properties 配置文件
redis.host=127.0.0.1 #IP地址
redis.port=6379 #端口号
redis.password= #密码为空

redis.maxIdle=300 #最大空闲连接数
redis.maxWaitMillis=1000 #连接时的最大等待毫秒数,小于零:阻塞不确定的时间,默认-1
redis.maxTotal=600 #最大活动对象数
redis.testOnBorrow=true #获取连接的时候检查有效性, 默认false
redis.testOnReturn=true #调用return Object方法时，是否进行有效性检查

3.配置application-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:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ">
<!--扫描redis配置文件 -->
<context:property-placeholder location="classpath:redis.properties" />

<!--设置连接池 -->
<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="${redis.maxIdle}" />
<property name="maxTotal" value="${redis.maxTotal}" />
<property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
<property name="testOnBorrow" value="${redis.testOnBorrow}" />
<property name="testOnReturn" value="${redis.testOnReturn}" />
</bean>

<!--设置链接属性 -->
<bean id="connectionFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
p:hostName="${redis.host}" p:port="${redis.port}" p:password="${redis.password}"
p:pool-config-ref="poolConfig" p:timeout="100000" />

<!-- Jedis模板配置 -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="connectionFactory" />
<!-- 如果不配置Serializer，那么存储的时候智能使用String，如果用User类型存储，那么会提示错误User can't cast
to String！！！ -->
<property name="keySerializer">
<bean
class="org.springframework.data.redis.serializer.StringRedisSerializer" />
</property>
<property name="valueSerializer">
<bean
class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
</property>
</bean>
</beans>

4.单元测试redis

import java.util.logging.Logger;

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;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:applicationContext-redis.xml"})
public class TestRedis {

@Autowired
private RedisTemplate redisTemplate;

private static final Logger log  = Logger.getLogger(TestRedis.class.getName());

@Test
public void test(){
redisTemplate.opsForValue().set("username", "熊二");
log.info("value："+redisTemplate.opsForValue().get("username"));
}
}

测试效果:
