spring启动找不到spring.liveBeansView.mbeanDomain配置

做项目时，启动tomcat报错

JNDI lookup for name [spring.liveBeansView.mbeanDomain] threw NamingException with message: Name [spring.liveBeansView.mbeanDomain] is not bound in this Context. Unable to find [spring.liveBeansView.mbeanDomain].. Returning null.
 可以正常运行项目，在网上查询解决方法，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。

解决办法就是在项目中的web.xml中添加如下配置：

 <context-param>
   <param-name>spring.profiles.active</param-name>
   <param-value>dev</param-value>
  </context-param>
  <context-param>
   <param-name>spring.profiles.default</param-name>
   <param-value>dev</param-value>
  </context-param>
  <context-param>
   <param-name>spring.liveBeansView.mbeanDomain</param-name>
   <param-value>dev</param-value>
  </context-param>
