• SpringMVC的整合完成CRUD(增删改查)

                                                 

    SpringMVC是一种基于Java的Web框架，它是Spring框架的一部分。SpringMVC通过使用MVC（Model-View-Controller）设计模式来组织和管理Web应用程序的开发。

    在SpringMVC中，Model代表数据模型，View代表用户界面，Controller负责处理用户请求并协调Model和View之间的交互。这种分层架构使得代码更加清晰、可维护和可扩展。

    一、项目创建

    创建一个Maven项目，项目名称为 : CloudJunzySSM 

    可以根据我的项目结构进行创建包，配置，接口，类(当然也可以根据自己的习惯创建)

    如果不知如何创建，可以关注本人的博客 : IDEA开发工具的安装及使用

    二、相关依赖

    将所有的引用依赖导入项目中，以下是所有依赖配置

    其中的项目名称需要根据自己的项目名称进行修改

    三、配置文件

    将项目中的web.xml配置文件修改为3.1并且增加配置

    其中有些会报编译错误，需要将后端代码完成即可

    创建名为CloudJun.tld (自定义分页并且配置)的配置文件

    四、后端代码

    配置完成，在右侧的maven中找到相应的配置文件进行自动生成接口及实体和配置文件

    不知道的可以根据我博客中的进行学习 : mybatis入门的环境搭建

    PagerAspect 创建切面类
    1. package com.CloudJun.aspect;
    2.  
    3. import com.CloudJun.utils.PageBean;
    4. import com.github.pagehelper.PageHelper;
    5. import com.github.pagehelper.PageInfo;
    6. import org.aspectj.lang.ProceedingJoinPoint;
    7. import org.aspectj.lang.annotation.Around;
    8. import org.aspectj.lang.annotation.Aspect;
    9. import org.springframework.stereotype.Component;

    16.  */
    17. @Component
    18. @Aspect
    19. public class PagerAspect {
    20.  
    21.     /**     * *..*Service.*Pager(..)
    22.      *      *   : 任何返回值
    23.      *      *.. : 任何包，不限层级
    24.      *      *biz : 以Biz结尾的类或者接口
    25.      *      *Pager : 以Pager结尾的方法
    26.      *      (..)  : 方法里有任意参数
    27.      *  符合上述条件，即为目标类或者方法
    28.      */
    29.  
    30.     @Around("execution(* *..*biz.*Page(..))")
    31.     public Object invoke(ProceedingJoinPoint args) throws Throwable {
    32.         Object[] params = args.getArgs();
    33.         PageBean pageBean = null;
    34.         for (Object param : params) {
    35.             if(param instanceof PageBean){
    36.                 pageBean = (PageBean)param;
    37.                 break;
    38.             }
    39.         }
    40.         if(pageBean != null && pageBean.isPagination())
    41.             PageHelper.startPage(pageBean.getPage(),pageBean.getRows());
    42.         Object list = args.proceed(params);
    43.         if(null != pageBean && pageBean.isPagination()){
    44.             PageInfo pageInfo = new PageInfo((List) list);
    45.             pageBean.setTotal(pageInfo.getTotal()+"");
    46.         }
    47.         return list;
    48.     }
    49.  
    50. }

    在自动生成的配置文件 HotelMapper.xml 中增加以下代码

    1.   <select id="selectHotelPage" resultType="com.CloudJun.model.Hotel" parameterType="com.CloudJun.model.Hotel" >
    2.     select  * from t_hotel
    3.     <where>
    4.       <if test="hname != null">
    5.         and hname like concat('%',#{hname},'%')
    6.       if>
    7.     where>
    8.   select>

    在自动生成的接口 HotelMapper 中增加以下代码

    List selectHotelPage(Hotel hotel);

    在自动生成的实体类中重写ToString方法

    在创建一个接口 Hotelbiz

    1. package com.CloudJun.biz;
    2.  
    3. import com.CloudJun.model.Hotel;
    4. import com.CloudJun.utils.PageBean;
    5.  
    6. import java.util.List;
    7.  
    8. public interface Hotelbiz {
    9.     int deleteByPrimaryKey(Long hid);
    10.  
    11.     int insert(Hotel record);
    12.  
    13.     int insertSelective(Hotel record);
    14.  
    15.     Hotel selectByPrimaryKey(Long hid);
    16.  
    17.     int updateByPrimaryKeySelective(Hotel record);
    18.  
    19.     int updateByPrimaryKey(Hotel record);
    20.  
    21.     List selectHotelPage(Hotel clazz, PageBean pageBean);
    22.  
    23. }

    自己在项目中共创建一个接口实现类 HotelbizImpl 

    1. package com.CloudJun.biz.impl;
    2.  
    3. import com.CloudJun.biz.Hotelbiz;
    4. import com.CloudJun.mapper.HotelMapper;
    5. import com.CloudJun.model.Hotel;

    7. import org.springframework.beans.factory.annotation.Autowired;
    8. import org.springframework.stereotype.Service;
    9.  
    10. import java.util.List;
    11.  
    12. /**
    13.  * @author CloudJun
    14.  * @create  2023-09-07 14:22
    15.  */
    16. @Service
    17. public class HotelbizImpl implements Hotelbiz {
    18.  
    19.     @Autowired
    20.     private HotelMapper hotelMapper;
    21.  
    22.     @Override
    23.     public int deleteByPrimaryKey(Long hid) {
    24.         return hotelMapper.deleteByPrimaryKey(hid);
    25.     }
    26.  
    27.     @Override
    28.     public int insert(Hotel record) {
    29.         return hotelMapper.insert(record);
    30.     }
    31.  
    32.     @Override
    33.     public int insertSelective(Hotel record) {
    34.         return hotelMapper.insert(record);
    35.     }
    36.  
    37.     @Override
    38.     public Hotel selectByPrimaryKey(Long hid) {
    39.         return hotelMapper.selectByPrimaryKey(hid);
    40.     }
    41.  
    42.     @Override
    43.     public int updateByPrimaryKeySelective(Hotel record) {
    44.         return hotelMapper.updateByPrimaryKeySelective(record);
    45.     }
    46.  
    47.     @Override
    48.     public int updateByPrimaryKey(Hotel record) {
    49.         return hotelMapper.updateByPrimaryKey(record);
    50.     }
    51.  
    52.     @Override
    53.     public List selectHotelPage(Hotel hotel, PageBean pageBean) {
    54.         return hotelMapper.selectHotelPage(hotel);
    55.     }
    56.  
    57. }
    PageBean创建一个分页工具类

    28.         List hotels = hotelbiz.selectHotelPage(hotel, pageBean);
    29.         request.setAttribute("list",hotels);
    30.         request.setAttribute("pageBean",pageBean);
    31.         return "hot/index";
    32.     }
    33.  
    34.     @RequestMapping("/del")
    35.     public String del(Hotel hotel,HttpServletRequest request){
    36.         hotelbiz.deleteByPrimaryKey(hotel.getHid());
    37.         return "redirect:list";
    38.     }
    39.  
    40.     @RequestMapping("/edit")
    41.     public String edit(Hotel hotel,HttpServletRequest request){
    42.         hotelbiz.updateByPrimaryKeySelective(hotel);
    43.         return "redirect:list";
    44.     }
    45.  
    46.     @RequestMapping("/add")
    47.     public String add(Hotel hotel,HttpServletRequest request){
    48.         hotelbiz.insertSelective(hotel);
    49.         return "redirect:list";
    50.     }
    51.  
    52.     @RequestMapping("/revise")
    53.     public String getHid(Hotel hotel,HttpServletRequest request){
    54.         if (hotel != null && hotel.getHid() != null && hotel.getHid()  != 0){
    55.             Hotel h = hotelbiz.selectByPrimaryKey(hotel.getHid());
    56.             request.setAttribute("h",h);
    57.         }
    58.         return "hot/edit";
    59.     }
    60.  
    61.  
    62.  
    63. }

    五、前端代码

    在WEB-INF文件中创建一个static包，以免配置文件报错

    再创建一个JSP后台显示界面 名为: index.jsp

    1. <%@ page language="java" contentType="text/html; charset=UTF-8"
    2.          pageEncoding="UTF-8"%>
    3. <%@ taglib uri="http://jsp.veryedu.cn" prefix="z"%>
    4. <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
    5. html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    6. <html>
    7. <head>
    8.     <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    9.     <link
    10.             href="https://cdn.bootcdn.net/ajax/libs/twitter-bootstrap/4.5.0/css/bootstrap.css"
    11.             rel="stylesheet">
    12.     <script
    13.             src="https://cdn.bootcdn.net/ajax/libs/twitter-bootstrap/4.5.0/js/bootstrap.js">script>
    14.     <title>酒店后台管理系统title>
    15.     <style type="text/css">
    16.         .page-item input {
    17.             padding: 0;
    18.             width: 40px;
    19.             height: 100%;
    20.             text-align: center;
    21.             margin: 0 6px;
    22.         }
    23.  
    24.         .page-item input, .page-item b {
    25.             line-height: 38px;
    26.             float: left;
    27.             font-weight: 400;
    28.         }
    29.  
    30.         .page-item.go-input {
    31.             margin: 0 10px;
    32.         }
    33.     style>
    34. head>
    35. <body>
    36. <form class="form-inline"
    37.       action="${pageContext.request.contextPath }/hot/list" method="post">
    38.     <div class="form-group mb-2">
    39.         <input type="text" class="form-control-plaintext" name="hname"
    40.                placeholder="请输入书籍名称">
    41. <%--        <input name="rows" value="10" type="hidden">--%>
    42.         
    43. <%--        <input name="pagination" value="false" type="hidden">--%>
    44.     div>
    45.     <button type="submit" class="btn btn-primary mb-2">查询button>
    46.     <a class="btn btn-primary mb-2" href="${pageContext.request.contextPath }/hot/revise">新增a>
    47. form>
    48.  
    49. <table class="table table-striped">
    50.     <thead>
    51.     <tr>
    52.         <th scope="col">房间编号th>
    53.         <th scope="col">房间名称th>
    54.         <th scope="col">房间类型th>
    55.         <th scope="col">操作th>
    56.     tr>
    57.     thead>
    58.     <tbody>
    59.     <c:forEach  var="h" items="${list }">
    60.         <tr>
    61.             <td>${h.hid }td>
    62.             <td>${h.hname }td>
    63.             <td>${h.htype }td>
    64.             <td>
    65.                 <a href="${pageContext.request.contextPath }/hot/revise?hid=${h.hid}">修改a>
    66.                 <a href="${pageContext.request.contextPath }/hot/del?hid=${h.hid}">删除a>
    67.             td>
    68.         tr>
    69.     c:forEach>
    70.     tbody>
    71. table>
    73. <z:page pageBean="${pageBean }">z:page>
    74.  
    75. body>
    76. html>

    创建一个jsp编辑界面，名称为 edit.jsp

    1. <%@ page contentType="text/html;charset=UTF-8" language="java" %>
    2. <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
    3. <html>
    4. <head>
    5.     <title>酒店管理编辑界面title>
    6. head>
    7. <body>
    8. <form action="${pageContext.request.contextPath }/hot/${empty h ? 'add' : 'edit'}" method="post">
    9.     房间编号:<input type="text" ${h!=null?'disabled':''} name="hid" value="${h.hid }"><br>
    10.     房间名称:<input type="text" name="hname" value="${h.hname }"><br>
    11.     房间类型:<input type="text" name="htype" value="${h.htype }"><br>
    12.     <input type="submit">
    13. form>
    14. body>
    15. html>

    六、功能测试

    最后开启服务器，在浏览器中请求以下地址( 请求地址是根据自己配置来进行访问的 ):                                         http://localhost:8080/ssm/hot/list

    访问后的显示效果为以下界面 : 

    增

    修

    删

    查

    给我们带来的收获

    学习使用SpringMVC完成CRUD可以给我们带来以下收获：

    总之，学习使用SpringMVC完成CRUD可以帮助我们提升自己的Web开发能力，掌握一种流行的Web框架，并且提高代码的可维护性和开发效率。
