一、问题描述

项目是基于dubbo的2.5.3版本，将注册中心zookeeper（zookeeper://127.0.0.1:2181）改为redis的（redis://127.0.0.1:6379），添加redis依赖关系，启动系统报异常“java.lang.NoSuchMethodError: redis.clients.jedis.JedisPool.<init>(Lorg/apache/commons/pool/impl/GenericObjectPool$Config;Ljava/lang/String;II)V”，具体错误日志如下所示

二、解决方法

1. 由于dubbo的2.5.3版本依赖的redis版本是2.0.0,添加正确的依赖关系如下

<dependency>@b@      <groupId>redis.clients</groupId>@b@       <artifactId>jedis</artifactId>@b@       <version>2.0.0</version>@b@</dependency>

2. 离线或在线online下载jedis-2.0.0的jar和pom文件（到本站的maven参考下载，或到maven2官网下载）

3. 因为jedis-2.0.0版本依赖的commons-pool-1.5.5，同时下载其jar和pom文件
