沒有HanderMapping發現 - 春季3.x - 控制器

我試了一切在陽光下得到這個工作..但無濟於事。沒有HanderMapping發現 - 春季3.x - 控制器

春3.0.5 搖籃 的Eclipse 碼頭嵌入式

它是一種簡單的控制器。但我得到No Handler Mapping消息

的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> 
      <param-name>contextConfigLocation</param-name> 
      <param-value>classpath*:/WEB-INF/spring/sch-rest.xml</param-value> 
    </init-param> 
    <load-on-startup>2</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>scheduler</servlet-name> 
    <url-pattern>/mvc/*</url-pattern> 
</servlet-mapping>

控制器：

package com.test.sch.controller; 

import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
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; 
    } 
}

SCH-rest.xml

刪除了從web.xml中

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

你爲什麼要加載你的彈簧配置文件兩次？ –

我最初正在加載一次...但我看到一些其他例子試圖這樣做。所以我也這樣做了。我嘗試了太多的東西來解決這個問題。但無濟於事。我只有一個上下文文件。 –

您的'ContextLoaderListener'和'DispatcherServlet'都被設置爲從相同的'xml'文件初始化它們相應的'ApplicationContext'。擺脫你的'ContextLoaderListener'。你不需要它。 –

下你應該做的第一件事就是刪除您ContextLoaderListener聲明及其context-param配置。目前，您正試圖加載sch-rest.xml文件兩次，一次用於ContextLoaderListener的WebApplicationContext，一次用於DispatcherServlet。這是不必要的，多餘的，並且在註冊@Controller處理程序方法時可能實際上會導致問題。瞭解更多關於這兩者之間的差別，在這裏：

您目前有以下

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

前綴classpath*:是wildcard prefix，試圖加載任何和所有的類路徑它在指定的路徑中找到的資源，如果沒有找到任何資源，它將不會出錯。這很可能發生在這裏。

您的程序奠定了像

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

，我覺得不太可能，上面的是你的類路徑中。

您可以簡單地指定（不classpath*:）

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

和Spring MVC將使用ServletContext解決的配置。
