修改项目的配置文件，log4j的日志输出级别修改为DEBUG，打印详细的错误信息后，
启动项目控制台输出有以下异常信息：
[org.springframework.jndi.JndiTemplate]-Looking up JNDI object with name [java:comp/env/spring.liveBeansView.mbeanDomain] [org.springframework.jndi.JndiLocatorDelegate]-Converted JNDI name [java:comp/env/spring.liveBeansView.mbeanDomain] not found - trying original name [spring.liveBeansView.mbeanDomain]. javax.naming.NameNotFoundException: Name [spring.liveBeansView.mbeanDomain] is not bound in this Context.

错误原因：
就是提供通过JMX来实时查看Spring放在application context里的bean列表功能的一个包,他会在你的配置文件里找一个叫"spring.liveBeansView.mbeanDomain"的环境变量,没找到,就报错了。
解决方法
如果你不使用任何 profiles 或 mbeans，可以在web.xml 中添加以下内容：
<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>
希望有人能提供比这更好的解决方案。
