Controller层

package com.example.dubbo.web.controller;import com.example.dubbo.model.User;import com.example.dubbo.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class UserController {@AutowiredUserService userService;/*** 响应前端请求，返回用用户详细信息以及总的用户个数*/@RequestMapping("/getUserDetail.do")public String getUserDetail(String id, Model model){//获取数据User user = userService.queryUserById(id);int userCount = userService.queryAllUserCount();//存放数据model.addAttribute("user", user);model.addAttribute("userCount", userCount);//跳转到用户详情页面return "userDetail";}}

web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><servlet><servlet-name>dispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:application.xml classpath:dubbo-link-consumer.xml</param-value></init-param></servlet><servlet-mapping><servlet-name>dispatcherServlet</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping></web-app>

返回给前端的响应页面：userDetail.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head><title>用户详情页</title></head><body><div>用户id:${user.id}</div><div>用户名:${user.name}</div><div>用户年龄:${user.age}</div><div>用户数量:${userCount}</div></body></html>
