Answer 1

大神，这个问题解决了吗，我也遇到了，求解！

Answer 2

然而这个bug应该是快两年前的bug了，你是有多久没更新了。。。

Answer 3

不是启动报错，是项目运行一段时间后就会出这个问题，的确是部署了多个应用，但是问题是另外一台服务器也是相同配置，却没出现过这个问题，我也准备升级版本试试看

Answer 4

回复
我也没说是启动报错啊。。。我说的是启动参数改一下。。

Answer 5

回复
嗯

Answer 6

不要懒，升级你的druid到最新版吧。

druid老版本有个bug，如果你在tomcat部署了两个应用，因为两个项目都使用了druid数据源，而且，指向的数据库也一致，会报错：ERROR [com.alibaba.druid.stat.DruidDataSourceStatManager] - unregister mbean error
解决办法：在tomcat的JVM参数中需要增加-Ddruid.registerToSysProperty=true 
同时，两个web应用的webAppRootKey的值也不能一致.
