这个问题已经在这里有一个答案：
为什么Spring MVC回应404，并报告“在DispatcherServlet中没有使用URI [...]发送HTTP请求的映射”？ 3个答案我几乎检查了几乎每一篇关于stackoverflow的相关文章，但我只是无法解决我的问题。
这里是代码：web.xml：
<display-name>Spring3MVC</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-servlet.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>spring</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> <url-pattern>/</url-pattern> <url-pattern>*.htm</url-pattern> </servlet-mapping> </web-app>为spring-servlet.xml：
<context:component-scan base-package="com.mycompany.elso" /> <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean>myController的：
public class myController { @RequestMapping("/hello") public ModelAndView helloWorld() { String message = "Hello World, Spring 3.0!"; return new ModelAndView("hello", "message", message); } }网页/ index.jsp：
<html> <head> <title>Spring 3.0 MVC Series</title> </head> <body> <a href="hello.html">Say Hello</a> </body> </html>网页/ WEB-INF / jsp / hello.jsp：
<html> <head> <title>Spring 3.0 MVC Series: Hello World - ViralPatel.net</title> </head> <body> ${message} </body> </html>所以当我启动应用程序index.jsp正确加载，但是当我点击href导航到hello.jsp我有一个404错误，服务器日志说：
No mapping found for HTTP request with URI [/Elso/hello.html] in DispatcherServlet with name 'spring'我查了几十篇这样的文章，但是我找不到错误，任何人都有什么想法呢？
This question already has an answer here:
Why does Spring MVC respond with a 404 and report “No mapping found for HTTP request with URI […] in DispatcherServlet”? 6 answersI checked out nearly every relevant article on stackoverflow already, but I just cant fix my problem.
Here is the code: web.xml:
<display-name>Spring3MVC</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-servlet.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>spring</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>*.html</url-pattern> <url-pattern>/</url-pattern> <url-pattern>*.htm</url-pattern> </servlet-mapping> </web-app>spring-servlet.xml:
<context:component-scan base-package="com.mycompany.elso" /> <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/> <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean>myController:
public class myController { @RequestMapping("/hello") public ModelAndView helloWorld() { String message = "Hello World, Spring 3.0!"; return new ModelAndView("hello", "message", message); } }Web Pages/index.jsp:
<html> <head> <title>Spring 3.0 MVC Series</title> </head> <body> <a href="hello.html">Say Hello</a> </body> </html>Web Pages/WEB-INF/jsp/hello.jsp:
<html> <head> <title>Spring 3.0 MVC Series: Hello World - ViralPatel.net</title> </head> <body> ${message} </body> </html>So when i launch the appication the index.jsp is loaded correctly but when i click on the href to navigate to hello.jsp i got a 404 error and the server log says:
No mapping found for HTTP request with URI [/Elso/hello.html] in DispatcherServlet with name 'spring'I've checked out dozens of articles like that, but I just can't find the mistake, anybody has any idea what could it be?
最满意答案
您可以尝试在myController Class之上添加一个@Controller注释，并尝试以下url /<webappname>/my/hello.html 。 这是因为org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping在myController类中为每个RequestMapping添加/ my 。
You could try and add an @Controller annotation on top of your myController Class and try the following url /<webappname>/my/hello.html. This is because org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping prepends /my to each RequestMapping in the myController class.
