My controller method looks like
我的控制器方法看起来像
@RequestMapping(value= "/recordList", method = RequestMethod.POST)
public ModelAndView getAssetListForUser(@RequestParam("ldapId") String ldapId,
final HttpServletRequest request){
Also, because I need the value if ldapId in the controller method, I am binding it in the calling method like this
另外，因为我需要控制器方法中的 ldapId 值，所以我将它绑定到调用方法中
request.setAttribute("ldapId", assetAssetEmp.getAssetEmpId());
Please help.
请帮忙。

It looks like your /recordListcontroller method only supports RequestMethod.POST.
hence you're getting the 405 GET Method not allowed error, since the redirect will issue a GET request.
看起来您的/recordList控制器方法仅支持RequestMethod.POST. 因此您会收到 405 GET Method not allowed 错误，因为重定向将发出 GET 请求。
to solve for it, try to give a GET version of your controller action. (the assetlist method) so that once the update happens, the asset list of the user can be returned via the GET method.
要解决它，请尝试提供控制器操作的 GET 版本。（资产列表方法），以便一旦发生更新，可以通过 GET 方法返回用户的资产列表。

The @RequestMappingannotation is your way to specify when your method is going to be called in an annotated controller. The RequestMethod.GETand RequestMethod.POSTarguments allow you to respond to the specific HTTPrequest type.
该@RequestMapping注释是你当你的方法是要在注释控制器被称为指定的方式。在RequestMethod.GET和RequestMethod.POST参数允许您具体回应HTTP请求类型。
providing method = RequestMethod.POSTto controller method actually making method to accept only HTTP POSTrequests.
提供method = RequestMethod.POST给控制器方法实际上使方法只接受HTTP POST请求。
