javax.management.InstanceAlreadyExistsException异常的问题 #1200

crab890715 · 2016-05-05T07:21:38Z

在tomcat 7.0下面部署两个项目，两个项目都是使用了druid数据连接池，单独启动一个项目的时候没有问题，把另外一个项目换为别的数据库连接池两个同时启动也没有问题，但是当两个项目放到这同一个tomcat下启动时就会出现下面的错误。
帮忙看一下这个问题：http://www.oschina.net/question/1427693_236304

什么版本，这个应该早就修复了啊

1.0.15，maven最新的1.0.18,没有做本地的中央库，所以直接用的网上的，但刚才用了最新的1.0.18也是存在这个问题的，直接导致jenkins发布失败

我是把相同的项目打了两个包放在同一个tomcat容器里面，但他们的数据源不一样，一个是生产环境的配置一个是测试环境的配置，由于现在机器少，所以暂时放在一起了

出错堆栈中怎么会没有druid调用栈？

这里是启动的日志报错信息：
catalina.txt

wenshao · 2016-05-05T09:32:26Z

这个更应该说是spring的bug，spring将实现了符合MBean规范的beans注册到mbeanserver中，但没处理好异常，所以悲剧了。

crab890715 · 2016-05-05T09:34:16Z

噢，好的，那我现在了解了，谢谢，我看看

wenshao · 2016-05-05T09:39:16Z

不过我可以尝试做一些改进，看是否能够自动匹配好

crab890715 · 2016-05-05T09:41:48Z

那基本上我了解具体问题出在什么地方了，或许我可以暂时寻求另外的途径解决这个问题

crab890715 · 2016-05-05T11:12:38Z

你好，感谢你的支持，我已经解决了，把spring的自动探测关闭掉了，应用还没有到全局复用对象的时候，即便使用也估计是使用RPC框架，以下是关闭jmx自动探测的spring配置

    <bean class="org.springframework.jmx.export.MBeanExporter">  
        <property name="autodetectModeName">  
            <value>AUTODETECT_NONE</value>  
        </property>  
    </bean>

Spring提供了4个取值：
AUTODETECT_NONE 不启用自动探测，需要手动向MBean Server进行注册，即通过MBeanExporter的beans属性进入注册；
AUTODETECT_MBEAN 在当前IOC容器中进行查找MBean组件；
AUTODETECT_ASSEMBLER 设置根据MBeanInfoAssembler的策略进行探测；
AUTODETECT_ALL 自动探测，是AUTODETECT_MBEAN和AUTODETECT_ASSEMBLER的并集。

那我关闭啦
