在DispatcherServlet中找不到名称为URI的HTTP请求的映射.... [英] No mapping found for HTTP request with URI.... in DispatcherServlet with name
问题描述
我已经检查了关于stackoverflow的几乎所有相关文章，但是我无法解决我的问题.
I checked out nearly every relevant article on stackoverflow already, but I just cant fix my problem.
这是代码: web.xml:
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:
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:
myController:
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:
Web Pages/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:
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>
因此，当我启动该appication时，index.jsp已正确加载，但是当我单击href导航到hello.jsp时，出现了404错误，并且服务器日志中显示:
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'
我已经检查了数十篇类似的文章，但我只是找不到错误，任何人都不知道这可能是什么吗?
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?
推荐答案
您可以尝试在myController类的顶部添加@Controller批注，然后
请尝试以下网址/<webappname>/my/hello.html.
这是因为org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping将/my 附加到myController类中的每个RequestMapping.
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.
