严重: The web application [/Chapter05] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@4c8b84]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@15ba1ef]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

刚开是看到还是以为少了什么jar包了

后来仔细一看 哦 原来少了一个配置节

忘了在web.xml中配置spring支持了

<!-- 配置spring支持 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 配置监听 -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener><wbr></wbr>
