ssm+reids+maven连接池的简单应用

1.首先开启reids服务

![70][]

2.设置密码

![70 1][]

3.导入架包（这里我用的是maven）

<dependency>
    	      <groupId>redis.clients</groupId>
    	      <artifactId>jedis</artifactId>
    	      <version>2.9.0</version>
    	    </dependency>

4.配置spring与redis整合(spring-jedis.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">
    
        
        
        
        
        <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
            
            <property name="maxTotal" value="200" />
            <property name="maxIdle" value="50" />
           <property name="maxWaitMillis" value="20000" />
            <property name="testOnBorrow" value="true"/>
            <property name="testOnReturn" value="true"/>
        </bean>
    
        <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
            <constructor-arg name="poolConfig" ref="jedisPoolConfig" />
            <constructor-arg name="host" value="127.0.0.1" />
            <constructor-arg name="port" value="6379" type="int" />
            <constructor-arg name="timeout" value="30000" type="int" />
            <constructor-arg name="password" value="123456789" />
            <constructor-arg name="database" value="0" type="int" />
        </bean>
    </beans>

（注意：我在web.xml会进行扫描，如：（详细配置请参照我的ssm整合博文））

<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>
    			classpath:spring/spring-*.xml
    		</param-value>
    	</context-param>

5.写一个控制器类测试

import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    import redis.clients.jedis.Jedis;
    import redis.clients.jedis.JedisPool;
    
    @Controller
    @RequestMapping("/Jedis")
    public class JedisController {
    	
    	    @Autowired
    	    private JedisPool jedisPool;//注入JedisPool
    
    	    @RequestMapping(value = "/set",method = RequestMethod.GET)
    	    @ResponseBody
    	    public String set(){
    	        //获取ShardedJedis对象
    	        Jedis jedis = jedisPool.getResource();
    	        //存入键值对
    	        jedis.set("zzf","hello jedis ok");
    	        //回收ShardedJedis实例
    	        jedis.close();
    
    	        return "set";
    	    }
    
    	    @RequestMapping(value = "/get",method = RequestMethod.GET)
    	    @ResponseBody
    	    public String get(){
    	        Jedis jedis = jedisPool.getResource();
    	        //根据键值获得数据
    	        String result = jedis.get("zzf");
    	        jedis.close();
    
    	        return result;
    	    }
    
    }

6.运行项目

![70 2][]

![70 3][]

![70 4][]

OK，可以看到reids与ssm整合成功了。
