MVC层的接口调用

在Controller中调用service服务方法

<%

         request.setCharacterEncoding("UTF-8");

         // Controller

         //1、 获取客户端的请求参数

         String name = request.getParameter("name");

         String code = request.getParameter("code");

         String idcard = request.getParameter("idcard");

         String email = request.getParameter("email");

         Student stu = new Student(name, code, idcard, email);

        

         //2、 调用Service层进行业务逻辑处理

         StudentService service = new StudentService();

         stu = service.regStudent(stu);

        

         //3、跳转到视图层显示结果数据

         if (stu.getId() ==null) {

%>

         <jsp:forward page="error.jsp" />

<%

         } else {

                   request.setAttribute("stu", stu);

%>

                   <jsp:forward page="success.jsp" />

<%

         }

        

%>
