org.springframework.web.servlet.PageNotFound noHandlerFound警告：找不到带URI的HTTP请求的映射

标签： java eclipse spring spring-mvc web-applications

我是Spring MVC框架的新手。我正在尝试使用Eclipse Juno和Tomcat（V 7.0.61）中的Spring 4设置示例代码库。我尝试了在不同论坛中陈述的不同选项，但没有一个工作。解决这个问题的任何帮助都会非常受欢迎！

以下是代码：

Web.xml中

    <?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
   <display-name>Spring MVC Application</display-name>

   <servlet>
      <servlet-name>HelloWeb</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <load-on-startup>1</load-on-startup>
   </servlet>

   <servlet-mapping>
      <servlet-name>HelloWeb</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

</web-app>

的HelloWeb-servlet.xml中

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

        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

HelloController.java 

package com.example;

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) {


      model.addAttribute("message", "Hello Spring MVC Framework!");

      return "hello";
   }
}

您错过了配置中的annotation-driven元素

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

   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

   http://www.springframework.org/schema/context/spring-context-3.0.xsd
   http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

   <!-- Enables the Spring MVC @Controller programming model -->
    <mvc:annotation-driven />

    <context:component-scan base-package="com.example" />
<!--    <mvc:default-servlet-handler /> -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

另请注意，您需要将扫描值设置为打包而不是类，因此请将设置从<context:component-scan base-package="com.example.HelloController" />修改为<context:component-scan base-package="com.example" />

答案 1 :(得分：0)

您需要将此添加到web.xml 

<context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>/WEB-INF/HelloWeb-servlet.xml</param-value>
</context-param>

<listener>
   <listener-class>
      org.springframework.web.context.ContextLoaderListener
   </listener-class>
</listener>

答案 2 :(得分：0)

我在不同的系统中进行了相同的设置并且工作正常，因此我认为Eclipse / Tomcat存在一些问题。

答案 3 :(得分：0)

如果hello.jsp放在jsp文件夹中，请将@RequestMapping（“/ hello”）更改为@RequestMapping（“/”）
