<!-- springmvc前臺的控制器 -->
	<servlet>

		<!-- contextConfigLocation不是必須的， 如果不配置contextConfigLocation， springmvc的配置檔案預設在：WEB-INF/servlet的name+"-servlet.xml" -->

<url-pattern>/</url-pattern>配置是攔截所有的請求，包括靜態資源（css,js等。。）

這樣頁面訪問的時候就會沒有效果，解決方案：

1. 在web.xml中配置如下：

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.xml</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.swf</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.zip</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.gif</url-pattern>
  </servlet-mapping>

  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.jpg</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.png</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
  </servlet-mapping>
 

  2 在spring.xml中增加配置如下：

<resources mapping="/resources/**" location="/resources/" />
  <resources mapping="/images/**" location="/images/" />
  <resources mapping="/js/**" location="/js/" />

<!-- 靜態資源對映  讓攔截器放開靜態資源-->
	<mvc:resources location="/WEB-INF/css/" mapping="/css/**"/>
	<mvc:resources location="/WEB-INF/js/" mapping="/js/**"/>

3  更換過濾器web.xml配置如下:

<servlet>
        <servlet-name>springDispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Map all requests to the DispatcherServlet for handling -->
    <servlet-mapping>
        <servlet-name>springDispatcherServlet</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>

<mvc:default-servlet-handler/>
