Question

我正在调试和现有的Spring MVC项目，我添加了一个servlet过滤器[ServletFilter]，我打算拦截所有传入的httprequests，但是为什么只有一些请求被截获，大部分不是？我该怎么做来拦截所有传入的请求？

我的servlet过滤器如下所示：

import ...

public class ServletFilter implements Filter
{    
  public void init(FilterConfig filterConfig) throws ServletException { }

  public void doFilter(ServletRequest servletRequest,ServletResponse servletResponse,FilterChain filterChain) throws IOException,ServletException
  {
    ...
  }
}

我的Java Web应用程序的web.xml如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

 <filter>
  <filter-name>Site_Filter</filter-name>
  <filter-class>com.builders.support.center.ServletFilter</filter-class>
 </filter>

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

 <servlet>
  <servlet-name>supportCenter</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

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

 <session-config>
  <session-timeout>360</session-timeout>
 </session-config>
 <welcome-file-list>
  <welcome-file>index.jsp</welcome-file>

 <error-page>
  <error-code>400</error-code>
  <location>/404error.jsp</location>
 </error-page>
 <error-page>
  <error-code>403</error-code>

 </error-page>
 <error-page>
  <error-code>500</error-code>

 </error-page>

我的supportCenter-servlet.xml看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
