Basic Spring MVC配置:使用InternalResourceViewResolver的PageNotFound

Question

我正在尝试运行第一个Spring 3 MVC设置.

我的应用程序在tomcat上运行,在"葡萄藤"的服务器环境中运行

出于测试目的,我正在尝试从中提取请求http://localhost:8080/grapevine/test以呈现内容WEB-INF/jsp/noSuchInvitation.jsp

当我尝试这个时,我得到了一个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'

我必须在某个地方错误地配置它,但我看不出我做错了什么.

这是所有相关的片段.

web.xml中:

<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>

从我的背景来看:

<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]
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'
DEBUG org.springframework.security.web.context.HttpSessionSecurityContextRepository  - SecurityContext contents are anonymous - context will not be stored in HttpSession. 
DEBUG org.springframework.web.servlet.DispatcherServlet  - Successfully completed request

这是因为<url-pattern>在你web.xml的"太宽".值/*表示servlet配置为接收所有请求,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.

你应该选择一个更具体的<url-pattern>,例如<url-pattern>/xyz/*</url-pattern>,以便你的URL成为http://localhost:8080/grapevine/xyz/test,然后它应该工作正常.
