在springmvc中配置jedis：

主要学习https://github.com/thinkgem/jeesite。一下代码均参考于此并稍作修改。

1.jedis

首先，需要添加jedis：

<!--jedis-->
<dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>2.8.0</version>
</dependency>

2.applicationContext-jedis.xml

然后，springmvc完成基本配置。添加jedispool的bean即可。在spring容器中添加applicationContext-jedis.xml：

在applicationContext-jedis.xml中添加：

<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-3.2.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.2.xsd">
    <!-- 加载配置属性文件 -->
    <context:property-placeholder ignore-unresolvable="true" location="classpath:db.properties" />

    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxIdle" value="300"/> <!--最大能够保持idel状态的对象数-->
        <property name="maxTotal" value="60000"/><!--最大分配的对象数-->
        <property name="testOnBorrow" value="true"/><!--当调用borrow Oject方法时，是否进行有效性检查-->
    </bean>

    <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
        <constructor-arg index="0" ref="jedisPoolConfig"/>
        <constructor-arg index="1" value="${redis.host}"/>
        <constructor-arg index="2" value="${redis.port}" type="int"/>
        <constructor-arg index="3" value="${redis.timeout}" type="int"/>
        <constructor-arg index="4" value="${redis.auth}"/>
    </bean>
</beans>

注解：参考的源码中的jedisPool配置只有三个参数：config，host，port。我复制后的结果总是getResource失败，因为我的redis添加了auth，所以猜测是不是没通过auth的原因。于是打开JedisPool的源码：
