Spring MVC基本配置:使用InternalResourceViewResolver的PageNotFound
问题内容:
我正在尝试运行第一个Spring 3 MVC安装程序。
我的应用程序在tomcat上运行,服务器上下文为“ grapevine”
为了进行测试,我试图从中获取请求http://localhost:8080/grapevine/test
以呈现WEB- INF/jsp/noSuchInvitation.jsp
当我尝试此操作时,出现404
,并且日志表明我的jsp不存在:
WARN org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/grapevine/WEB-INF/jsp/noSuchInvitation.jsp] in DispatcherServlet with name 'grapevine'
我一定在某处配置错误,但是看不到我做错了什么。
这是所有相关的摘要。
Web.xml:
<servlet>
<servlet-name>grapevine</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>grapevine</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
从我的角度来看:
<mvc:annotation-driven />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
控制器:
@Controller
public class ParticipantInvitationController {
@RequestMapping("/test")
public ModelAndView test()
{
return new ModelAndView("noSuchInvitation");
}
日志:
DEBUG org.springframework.web.servlet.DispatcherServlet - Rendering view [org.springframework.web.servlet.view.JstlView: name 'noSuchInvitation'; URL [/WEB-INF/jsp/noSuchInvitation.jsp]] in DispatcherServlet with name 'grapevine'
DEBUG org.springframework.web.servlet.view.JstlView - Forwarding to resource [/WEB-INF/jsp/noSuchInvitation.jsp] in InternalResourceView 'noSuchInvitation'
DEBUG org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'grapevine' processing GET request for [/grapevine/WEB-INF/jsp/noSuchInvitation.jsp]

DEBUG org.springframework.web.servlet.DispatcherServlet - Successfully completed request
问题答案:
这是因为<url- pattern>
您web.xml
的太“宽”了。值的/*
意思是servlet被配置为接收所有请求,并且包括从servlet到JSP的请求。您看到的错误消息来自DispatcherServlet
,它正在接收自己的转发请求。
您应该选择一个更具体的<url-pattern>
,例如<url-pattern>/xyz/*</url- pattern>
,这样您的URL就会变成http://localhost:8080/grapevine/xyz/test
,然后就可以正常工作了。
