异常贴完，开始解决问题。

解决方法：

1、我使用到了以下开源框架货软件：

spring做IOC，AOP和事务管理（版本号：4.0.2）

mybatis做dao层，用来处理dml（版本号：3.2.6）

dubbo做内部通讯，提供接口给客户端调用（版本号：2.5.3），dubbo的注意事项请看（springmvc+dubbo+mybatis整合异常）

zookeeper用来做服务的注册中心，进行服务治理（按本号：3.3.6）

redis用来做缓存，以提高访问速度（版本号：Redis 3.2.1）

2、使用以下对应jar版本如下：

    <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.7.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-redis -->
        <dependency>
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-redis</artifactId>
            <version>1.6.0.RELEASE</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/commons-pool/commons-pool -->
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
            <version>2.0</version>
        </dependency>
