spring启动找不到spring.liveBeansView.mbeanDomain配置

        今天在做一个dubbo服务端的时候，启动成功，dubbo也注册成功，但是启动日志中就出现[java:comp/env/spring.liveBeansView.mbeanDomain] not found这个日志，网上搜搜，果然很多人出现过这个问题。

 错误原因：就是spring-context.jar包中提供通过JMX来实时查看spring放在applicationContext里的bean列表功能，会在项目配置文件里找一个叫"spring.liveBeansView.mbeanDomain"的环境变量,没找到,就报错了。

j解决办法就是在项目中的web.xml中添加如下配置：

	
		spring.profiles.active
		dev
	
	
		spring.profiles.default
		dev
	
	
		spring.liveBeansView.mbeanDomain
		dev
