Question

我的应用程序不能处理请求映射，请求总是使用相同的方法handleRequest，控制器是RestController.java，当路径为/ REST2 / *时，URL重定向到它，它运行良好但总是用同样的方法。但方法＆＃34;更新＆＃34;当我向locahost发送请求时，它永远不会工作：9080 / myapp / REST2 / rrr，如果我更改了URL，即localhost：9080 / myapp / REST2 / XXX，请求也将处理handleRequest方法。

RequestMapping运行不好，我尝试过其他解决方案但是没有工作..

你有什么想法吗？

Restcontroller.java

)$

弹簧servlet.xml中

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

尝试将@Controller和@RequestMapping注释添加到RestController类，如下所示：

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

并添加method=RequestMethod.POST这样的@RequestMapping方法：

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

控制器@RequestMapping错误URL
