这是我的配置文件：

web.xml

<context-param>     
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/root-context.xml</param-value>
</context-param>

<context-param>
    <param-name>defaultHtmlEscape</param-name>

</filter>

<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

这是root-context.xml
