Question

我使用了 AngularJS 和 Servlet 。单击“提交”按钮后，输入的数据将仅显示在URL栏中，但无法访问凭据Servlet。没有显示错误。我在下面提供了我的代码。谁能告诉我为什么无法访问servlet？

的index.html

＆＃13;

<!DOCTYPE html>
<html>
<head>
<script src="resources/js/angular.min.js"></script>

<script>
	var formApp = angular.module('formApp', []);

	formApp.controller('formController', function($scope, $http) {

		$scope.user = {};

		$scope.submitForm = function() {
			$http({
				method : 'POST',
				url : 'http://localhost:9090/UserAuthentication/Credentials',
				data : JSON.stringify($scope.user),
				headers : {
					'Content-Type' : 'application/json'
				}
			}).success(function(data) {
				alert("Controller is hit!");
			});
		};
	});
</script>

</head>
<body>
	<div ng-app="formApp" ng-controller="formController">
		<h1>User Details</h1>
		<form name="itemForm" ng-submit="submitForm()">
			UserName: <input name="username" type="text" ng-model="user.username">
			<br />Password: <input name="password" type="password"
				ng-model="user.password"> <br /> <input type="submit"
				value="Submit">
		</form>
	</div>
</body>
</html>

凭据Servlet：

package com.controller;

import java.io.BufferedReader;

@WebServlet("/Credentials")
public class Credentials extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public Credentials() {
        super();
    }


    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
     *      response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        String jsonData = " ";

        BufferedReader reader = request.getReader();
        String line = null;
        while ((line = reader.readLine()) != null) {
            jsonData += line + "\n";
        }
        System.out.println(jsonData);
    }

}

angular js：ng-submit没有命中控制器
