Spring警告在DispatcherServlet中找不到带有URI [/SpringHello/WEB-INF/jsp/hello.jsp]的HTTP请求的映射，名称为“spring”

标签： eclipse spring spring-mvc 

I tried to to load a simple example of spring mvc with a simple jsp but failed with the following error: No mapping found for HTTP request with URI [/SpringHello/WEB-INF/jsp/hello.jsp] I'm using Spring 3.2.2. I really appreciate your help here. I tried several thing but still it seems that I can not map my jsp page in the controller.

我尽可能地在这里查看其他答案，但似乎没有什么能完全符合我的问题/解决我的问题。基本上

我觉得我已正确完成了映射，但显然我没有。所以在这里我会发布任何看起来可能相关的文件。

我的控制器类是： 

    package net.viralpatel.spring3.controller;

    import org.springframework.stereotype.Controller;
    import org.springframework.ui.ModelMap;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;

    @Controller
    @RequestMapping("/hello")
    public class HelloController{

       @RequestMapping(method = RequestMethod.GET)
       public String printHello(ModelMap model) {
           System.out.println("Hello Spring MVC Framework!**********************");
          model.addAttribute("message", "Hello Spring MVC Framework!");
          return "hello";
       }

    }

我的web.xml文件是： 

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns="http://java.sun.com/xml/ns/javaee"

            <url-pattern>/*</url-pattern>
        </servlet-mapping>
    </web-app>

我的spring-servlet.xml文件是： 

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    http://www.springframework.org/schema/context/spring-context-3.0.xsd">

        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix">
                <value>/WEB-INF/jsp/</value>
            </property>
            <property name="suffix">
                <value>.jsp</value>
            </property>
            </bean>

    </beans>

我的hello.jsp是： 

    <html>
    <head>
        <title>Spring 3.0 MVC Series: Hello World - ViralPatel.net</title>
    </head>
    <body>
        ${message}
    </body>
    </html>

    I am trying to run my hello.jsp with "http:ipAddress:8080/SpringHello/hello" but I am getting "HTTP Status 404 - /SpringHello/hello" .

请帮助我，我是春天新手，我花了3天多时间来解决这个问题。

答案 0 :(得分：0)

您没有路径/SpringHello/WEB-INF/jsp/hello.jsp的处理程序。您应该将您的请求发送到

/SpringHello/hello

由您的HelloController类映射。
