Redis與Spring集成

redis與Spring集成比較簡單，本文不涉及Spring的一些基本概念，讀都需先具有Spring的相關知識。

先在maven中添加依賴

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"

    <property name="maxWait" value="1000" />    <!--最大等待時間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操做redis的類

/**
 * 
 */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，請讀者本身完成。

<bean id="redisDao" class="com.zolcorp.mahout.dao.RedisDao"></bean>

註冊bean

main函數以下：

/** *  */ 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...}
