java - 未找到 HanderMapping - Spring 3.x - Controller

标签 java eclipse spring spring-mvc model-view-controller

我尝试了一切方法来使其正常工作..但无济于事。

Spring 3.0.5 Gradle eclipse 嵌入 jetty

它是一个简单的 Controller 。但我收到 No Handler Mapping 消息

web.xml

<display-name>Scheduling</display-name>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:/WEB-INF/spring/sch-rest.xml</param-value>
 </context-param>

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

<!-- Spring MVC -->
<servlet>
    <servlet-name>scheduler</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>

</servlet>

<servlet-mapping>

</servlet-mapping>

Controller :

package com.test.sch.controller;

import org.slf4j.Logger;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class TestController {

   @RequestMapping(value="/job", method=RequestMethod.GET)
   @ResponseBody
   public String test(@RequestParam (value = "name", required = false) String name) throws Exception{

     System.out.println("name:" + name);
     return "Yes, I got it, " + name;
   }
}

更新1:

从 web.xml 中删除了以下内容

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:/WEB-INF/spring/sch-rest.xml</param-value>
 </context-param>

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

最佳答案

您应该做的第一件事就是删除 ContextLoaderListener声明及其context-param配置。目前，您正在尝试加载 sch-rest.xml文件两次，一次为ContextLoaderListener的WebApplicationContext一次为 DispatcherServlet的。这是不必要的、多余的，并且实际上可能会在注册时导致问题 @Controller处理程序方法。请在此处详细了解这两者之间的差异:

您目前拥有以下内容

<init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:/WEB-INF/spring/sch-rest.xml</param-value>
</init-param>

前缀classpath*:是 wildcard prefix它尝试加载在指定路径中找到的所有类路径资源，如果没有找到任何资源，也不会出错。这很可能就是这里发生的事情。

你的程序的布局如下

WEB=INF\
   [...]
   spring
      sch-rest.xml

我发现上面的内容不太可能在你的类路径上。

您可以简单地指定(不带 classpath*: )

<init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/sch-rest.xml</param-value>
</init-param>

Spring MVC 将使用 ServletContext来解决配置问题。
