如何在Struts2中强制方法仅接受POST参数？

Question

I have the following method, which I need to force to accept only POST parameters. This method receives id of the selected user to retrieve its object. I need to force this method to just accept posted ids not those sent by GET.

   public class Users{
     private long uid;

     public String show() {
            UsersModel usrModel = new UsersModel();
            return usrModel.retrieveUser(uid); //uid paramets will be sent by client to 
                                              //retrieve object of selected user
     }
     ....
   }

Answer 1

You can also create an interceptor to check for all request that you want to be only using post methods, see the following example:

HttpServletRequest request = ServletActionContext.getRequest();
...
request.getMethod().equals("POST") // check using this condition.

See the following link Restrict Struts2 action to post method only

Answer 2

try this:

String method = ServletActionContext.getRequest().getMethod();
if (method.equals("POST") {
    // do something
} else {}

Answer 3

try this,

 HttpServletRequest request=(HttpServletRequest) ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);
 if(request.getMethod().equals("POST"))
    {
             //your code
              return "accept";
    }else{
             return "not_accept";
    }
