MVC REST Servlet Web Gmail

首先配置WEB.XML：

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



	<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<!-- 覆盖default servlet的/, springmvc servlet将处理原来处理静态资源的映射 -->
	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

	<!--
		浏览器不支持put,delete等method,由该filter将/blog?_method=delete转换为标准的http
		delete方法
	-->
	<filter>
		<filter-name>HiddenHttpMethodFilter</filter-name>
		<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>HiddenHttpMethodFilter</filter-name>
		<servlet-name>springmvc</servlet-name>
	</filter-mapping>

</web-app>

然后配置springmvc-servlet.xml

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

<!-- 
	修改说明:
	1.修改<context:component-scan以确定要加载的controller,默认为com.**.controller
	2.修改class=ControllerClassNameHandlerMapping节点的pathPrefix以确定要生成的前缀
 -->
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p" 
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-2.5.xsd"
    default-autowire="byName"   >
    <!-- 对web包中的所有controller类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
	<context:component-scan base-package="com.**.controller" />
	<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
	<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->		
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />  
	<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
	 p:prefix="/WEB-INF/pages/" p:suffix=".jsp"/>

        
</beans>

6 楼唯快不破 2010-07-05

请问楼主为什么用ui.Model，而不用ModelAndView？

5 楼 freecode 2010-06-03

参考了spring3.0 sample,我现在采用：
<filter>
    <filter-name>UrlRewriteFilter</filter-name>
    <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>

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


<servlet>
    <servlet-name>app</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>app</servlet-name>
    <url-pattern>/app/*</url-pattern>
</servlet-mapping>

urlrewrite.xml:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN" "http://tuckey.org/res/dtds/urlrewrite3.0.dtd">

<rule>

<outbound-rule>
    <from>/app/**</from>

</urlrewrite>

这个问题我已经解决了，请查看我写的这篇文章

Java代码

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

你这样处理以后，那图片文件和样式文件不都经过这层过滤了？
比如 http://www.abc.com/a.gif
http://www.abc.com/c.css
能够正常获取到吗？
我这里正常获取不到，麻烦详细解释一下，

我这里遇到的情况和这个一样，在网上找了许多资料，也没发现更好的解决办法，我用的是spring3.0

我已经解决了这个问题，看到联系我，发我邮箱~
