Question

我在Spring MVC应用程序中使用了四个过滤器，今天意识到过滤器的排序也很重要（在调试浪费了大量时间之后，参考Spring security tags in sitemesh decorator修复了装饰问题）。我仍然需要帮助找到这些过滤器的正确顺序，因为我还在学习Spring。请指教。

我的web.xml是：

http://java.sun.com/xml/ns/j2ee/web-app_3_1.xsd" 版本=＆＃34; 3.1＆＃34;＆GT;

<display-name>Sample App</display-name>
<description>Sample Application</description>

<context-param>
    <description>locations of the Spring configuration files</description>
    <param-name>contextConfigLocation</param-name>
    <param-value>
      classpath:spring/application-service.xml,
      classpath:spring/application-servlet.xml,
      classpath:spring/application-dao.xml,
      classpath:spring/application-security.xml,
      classpath:spring/application-social.xml,
      classpath:spring/application-mailservice.xml,
    </param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!--- Servlet that dispatches request to registered handlers (Controller implementations). -->
<servlet>
    <servlet-name>application</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/application-servlet.xml</param-value>
</init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>application</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>httpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>httpMethodFilter</filter-name>
    <servlet-name>application</servlet-name>
</filter-mapping>
  <!-- Enables Spring Security -->
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>
        org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
</filter>

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

<filter>
  <filter-name>sitemesh</filter-name>
  <filter-class>org.sitemesh.config.ConfigurableSiteMeshFilter</filter-class>
</filter>
    <filter-mapping>
  <filter-name>sitemesh</filter-name>
  <url-pattern>/*</url-pattern>     </filter-mapping>

<filter>
    <filter-name>encoding-filter</filter-name>
    <filter-class>
        org.springframework.web.filter.CharacterEncodingFilter
    </filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
</filter>

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

Spring web.xml中的过滤器顺序正确
