SpringMVC错误之No mapping found for HTTP request with [url]

spring的配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd"> 
<bean id="/productSave.action" class="Controller.ProductSaveController"></bean>

<bean id="/productForm.action" class="Controller.ProductFormController"></bean>

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>

其中配置了视图解析器viewResolver，ProductSaveController和ProductFormController两个实现了org.springframework.web.servlet.mvc.Controller接口的实现类根据不同的url返回不同的视图路径，ProductFormController的代码如下：

package Controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class ProductFormController implements Controller {

public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) {

//这里只返回了一个视图对象
return new ModelAndView("productFrom");
}
}

web.xml的配置如下：

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
<display-name>Archetype Created Web Application</display-name>

<!-- The front controller of this Spring Web application, responsible for
handling all application requests -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<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>/</url-pattern>
</servlet-mapping>
</web-app>

错误原因：这里url-pattern拦截了所有请求，报错原因就在于当IOC容器注入一个bean时（比如id=”/productForm.action”的bean），该bean将返回一个view的路径，而 DispatcherServlet又将该view的路径当作另一个请求，再次对其进行拦截，而此时spring的配置文件中并没有对这个路径进行映射，因此报错。

解决方案：

更改拦截url，只拦截以.action结尾的请求：

<url-pattern>*.action</url-pattern>

在spring的配置文件中配置访问静态资源的servlet：

<mvc:default-servlet-handler/>
