Basic Spring MVC config: PageNotFound using InternalResourceViewResolver
提问by Marty Pitt
I'm trying to get a first Spring 3 MVC setup running.
我正在尝试运行第一个 Spring 3 MVC 设置。
My app is running on tomcat, with in the server context of "grapevine"
我的应用程序在 tomcat 上运行，在“grapevine”的服务器上下文中
For the purposes of testing, I'm trying to get requests from http://localhost:8080/grapevine/testto render the contents of WEB-INF/jsp/noSuchInvitation.jsp
出于测试的目的，我正在尝试获取请求http://localhost:8080/grapevine/test以呈现WEB-INF/jsp/noSuchInvitation.jsp
When I try this, I'm getting a 404, and the logs suggest that my jsp isn't present:
当我尝试这个时，我得到一个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'
I must have mis-configured this somewhere, but I can't see what I've done wrong.
我一定是在某处错误地配置了它，但我看不出我做错了什么。
Here's all the relevant snippets.
这是所有相关的片段。
Web.xml:
网页.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>
From my context:
从我的上下文来看：
<mvc:annotation-driven />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
Controller:
控制器：
@Controller
public class ParticipantInvitationController {
@RequestMapping("/test")
public ModelAndView test()
{
return new ModelAndView("noSuchInvitation");
}
Log:
日志：

This is because the <url-pattern>in your web.xmlis too "wide". A value of /*means that the servlet is configured to receive all requests, and that includes the request from the servlet to the JSP. The error message you're seeing is from DispatcherServlet, which is receiving its own forwarded request.
这是因为<url-pattern>in yourweb.xml太“宽”了。值/*表示 servlet 被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。
You should pick a more specific <url-pattern>, e.g. <url-pattern>/xyz/*</url-pattern>, so that your URL then becomes http://localhost:8080/grapevine/xyz/test, and then it should work fine.
您应该选择一个更具体的<url-pattern>，例如<url-pattern>/xyz/*</url-pattern>，以便您的 URL 变为http://localhost:8080/grapevine/xyz/test，然后它应该可以正常工作。

Just replace /*to /as your url-pattern. It will work...
只需将/*to替换/为您的url-pattern. 它会工作...

Solution 1: You can register your servlet at *.html and *.json (or xml, gif, png...):
解决方案 1：您可以在 *.html 和 *.json（或 xml、gif、png...）处注册您的 servlet：
<servlet>
<servlet-name>RestServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>RestServlet</servlet-name>
<url-pattern>/</url-pattern>
<url-pattern>*.html</url-pattern>
<url-pattern>*.json</url-pattern>
</servlet-mapping>
Solution 2: If you want to keep your servlet mapped at /*, add the following to your spring.xml file:
解决方案 2：如果要将 servlet 映射到/*，请将以下内容添加到 spring.xml 文件中：
<mvc:default-servlet-handler/>
And this to your web.xml file:
这到您的 web.xml 文件：
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>/WEB-INF/jsp/*</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
</servlet>
The rationale is explained here: spring, web.xml. This will register an explicit handler for JSP pages with greater precedence than /*.

BEWARE: This could be a misleading error message. It just happened to me.
当心：这可能是一个误导性的错误消息。它只是发生在我身上。
Even thought the error message unexpectedly contains the /ContextName/... at the beginning of the path, it could still be a misspelling in either the InternalResourceViewResolver prefix:
即使认为错误消息在路径的开头意外包含 /ContextName/... ，它仍然可能是 InternalResourceViewResolver 前缀中的拼写错误：
<property name="prefix" value="/WEB-INF-typo-Here/jsp/"/>
or the file path itself.
或文件路径本身。
Now that I fixed my misspelling, it works fine. I don't know why the context shows in the error message, and it really caused me to ignore my silly typo and attempting to try the wonderful other contributions to this question. Don't let it happen to you!
现在我修正了我的拼写错误，它工作正常。我不知道为什么错误消息中会显示上下文，这确实让我忽略了我愚蠢的错字并尝试尝试对该问题的其他精彩贡献。不要让它发生在你身上！
BTW, I am using Spring 4.0.0 release.
顺便说一句，我使用的是 Spring 4.0.0 版本。

for me I solved the problem by using .jsp templates and not just .html.
对我来说，我通过使用 .jsp 模板而不仅仅是 .html 解决了这个问题。
