weblogic下部署(含JedisResourcePool类引入java.lang.NoSuchMethodError:Equivalence.equals()解决

weblogic下部署(含JedisResourcePool类引入报错Caused By: java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.sameThreadExecutor()Lcom/google/common/util/concurrent/ListeningExecutorService;解决

把解决思路与解决办法共享给大家。

背景：项目引入REDIS在tomcat8.5下开发环境功能正常，当打成war包部署在weblogic下部署报错，报错信息如下：

一、经过初步分析com.google.common.util.concurrent.MoreExecutors.sameThreadExecutor在工程引入JAR包中存在，并且有此方法。但是部署在weblogic却报方法不存在。初步定位为JAR包冲突。

1、网上建议更新guava.jar到18.0版本。升级完成后部署jar包后报错依旧存在。

gradle脚本：

  compile ("com.google.guava:guava:18.0")

2、考虑当前war包下的jar与weblogic下jar存在冲突。解决方案：指定对应的代码为引入war包中的lib包。在工程webligc.xml下设定  prefer-application-packages属性，把当前的jar指定为工程中代码。

具体实现如下：

  
       
      
            com.google.common.*
       
  

如此解决后，jar包冲突问题就迎刃而解了。
