java - Spring/Java Web : how can I know a request is a form post?

Question

我正在做一个 Spring 网站。该网站有许多访问者可以访问的页面。它还允许访问者填写并提交一些表格。

我想使用 Spring 拦截器(作为中心位置)来检查访问者的每个 Web 请求。如何判断网络请求是 get 请求还是表单 post 请求？

感谢和问候!

Answer 1

您可以按如下方式使用 getMethod() -

import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import org.springframework.stereotype.Component;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@Component
public class MyInterceptor extends HandlerInterceptorAdapter {
    public boolean preHandle(HttpServletRequest request,
            HttpServletResponse response, Object handler) throws Exception {
        System.out.println("Request Intercepted for : "
                + request.getRequestURI());
        System.out.println("Request type : "
                + request.getMethod());
        return true;
    }
}

java.lang.String getMethod()

Returns the name of the HTTP method with which this request was made, for example, GET, POST, or PUT. Same as the value of the CGI variable REQUEST_METHOD.

Returns: a String specifying the name of the method with which this request was made
