控制器 @RequestMapping 错误 URL

Question

我的应用程序不适用于请求映射，请求始终使用相同的方法 handleRequest，控制器是 RestController.java 并且 URLs 在具有路径 /REST2/ 时重定向到它*，它运作良好，但始终使用相同的方法。但是当我将请求发送到 locahost:9080/myapp/REST2/rrr 并且如果我更改 URL 即 localhost:9080/myapp/REST2/XXX 时，方法 "update" 永远不会工作该请求将转到 handleRequest 方法。

RequestMapping 效果不佳，我尝试了其他解决方案但效果不佳..

你有什么想法吗？

Restcontroller.java

public class RestController implements Controller{
private Configuration config;
private static String[] requestHeaders = {"accept", "pragma"};
private static String[] responseHeaders = {};    

public void setConfig(Configuration config)
{
    this.config = config;
}


@RequestMapping(value="/rrr") public ModelAndView update(HttpServletRequest request, HttpServletResponse response) throws Exception 
     {

    String asset_name = request.getParameter("assetid");
     response.setContentType("text/plain");  // Set content type of the response so that jQuery knows what it can expect.
     response.setCharacterEncoding("UTF-8"); // You want world domination, huh?

     String values = "Working"+ asset_name;
     response.setContentLength(values.length());

     PrintWriter out = response.getWriter();

    out.println(values);
    return null;

}

@RequestMapping(value ="/home")public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception 
{
    Arrays.sort( requestHeaders );
    Arrays.sort( responseHeaders );
    String values;

    String asset_name = request.getParameter("assetid");
    ...
   response.setContentLength(values.length());
    //
    PrintWriter out = response.getWriter();

    out.println(values);


    return null;
}}

Answer 1

尝试向 RestController 类添加 @Controller 和 @RequestMapping 注释，如下所示：

  @Controller
  @RequestMapping(value="/REST2")
  public class RestController implements Controller{

并添加 method=RequestMethod.POST 方法 @RequestMapping 如下：

  @RequestMapping(value ="/home", method=RequestMethod.POST)
  ...
  @RequestMapping(value ="/rrr", method=RequestMethod.POST)
