redis spring怎么整合

Answer 1

redis与Spring集成比较简单，本文不涉及Spring的一些基本概念，读都需先具备Spring的相关知识。
先在maven中添加依赖
pom.xml
<!-- redis -->
<dependency>
‍ <groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.0.0</version>
</dependency> ‍
<!-- redis -->

applicationContext-redis.xml加入你的Spring context
<?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"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xsi:schemaLocation="http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0xsd
http://www.springframework.org/schema/data/mongo
http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <property name="maxActive" value="50" /> <!--最大连接数-->
<property name="maxIdle" value="10" /> <!--最大空闲数-->
<property name="maxWait" value="1000" /> <!--最大等待时间ms-->
<property name="testOnBorrow" value="true" />
</bean>
<bean id="jedis.shardInfo" class="redis.clients.jedis.JedisShardInfo">
<constructor-arg index="0" value="172.21.1.121" />
<constructor-arg index="1" value="6379" />
</bean>
<bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool"> <constructor-arg index="0" ref="jedisPoolConfig" />
<constructor-arg index="1">
<list>
<ref bean="jedis.shardInfo" />
</list>
</constructor-arg>
</bean>
</beans>

RedisDao.java操作redis的类
/**
*
*/package com.zolcorp.mahout.dao;
import org.springframework.beans.factory.annotation.Autowired;
import redis.clients.jedis.ShardedJedis;
import redis.clients.jedis.ShardedJedisPool;
/**
* @author hadoop
*
*/
public class RedisDao {
@Autowired
private ShardedJedisPool shardedJedisPool;
public void set(String key, String value) {
ShardedJedis jedis = shardedJedisPool.getResource();
jedis.set(key, value);
}
public String get(String key) {
ShardedJedis jedis = shardedJedisPool.getResource();
return jedis.get(key);
}‍
}

其它一些方法，请读者自己完成。
<bean id="redisDao" class="com.zolcorp.mahout.dao.RedisDao"></bean>

注册bean
main函数如下：
/**
*
*/
package com.zolcorp.mahout.main;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContex; import com.zolcorp.mahout.dao.RedisDao;
/**
* @author hadoop
*
*/
public class RedisMain {
/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext context = new FileSystemXmlApplicationContext( new String[] { "classpath:applicationContext-bean.xml",
"classpath:applicationContext-datasource.xml",
"classpath:applicationContext-redis.xml"});
RedisDao redisDao = context.getBean("redisDao", RedisDao.class);
redisDao.set("test", "test-----ming...");
System.out.println(redisDao.get("test")); }//test-----ming...

}
