SpringBoot-Vue实现增删改查及分页小DEMO

前言

主要通过后端 Spring Boot 技术和前端 Vue 技术来简单开发一个demo，实现增删改查、分页功能以及了解Springboot搭配vue完成前后端分离项目的开发流程。

开发栈

前端

• 开发工具：WebStorm
• 开发框架：vue + axios
• 包管理工具: npm
• 打包工具：webpack

后端

• 开发工具：IDEA
• 开发框架：Springboot + mybatis
• 打包工具：maven
• 数据库： MySQL

PS：假设以上的的工具你都安装好啦，写CRUD小DEMO时进坑了，这篇blog参考一下，仅供参考，仅供参考??，，如有不足请不吝赐教。

后端开发环境搭建

1、File->New->Project...

2、选择 Spring Initializr ，然后选择默认的 url 点击next

3、勾选Spring Web、SQL模板，next

4、点击finish，搭建完成

后端开发过程

1、更新pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>springboot-mybatis</name>

    <!-- Spring Boot 启动父依赖 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
    </parent>

    <properties>
        <mybatis-spring-boot>1.2.0</mybatis-spring-boot>
        <mysql-connector>5.1.39</mysql-connector>
    </properties>

    <dependencies>

        <!-- Spring Boot Web 依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- Spring Boot Test 依赖 -->
        <dependency>

            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <!-- Spring Boot Mybatis 依赖 -->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>${mybatis-spring-boot}</version>
        </dependency>

        <!-- MySQL 连接驱动依赖 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>

            <version>4.12</version>
        </dependency>
    </dependencies>
</project>

2、新建 demo\src\main\java\com\example\demo\entity\User.java

package com.example.demo.entity;

public class User {
    private int userId;
    private String userDate;
    private String userName;
    private String userAddress;

   //省略get() and set()
}

3、更新demo\src\main\resources\application.properties

## 数据源配置
spring.datasource.url=jdbc:mysql://localhost:3306/test1?useUnicode=true&characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=123
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

## Mybatis 配置
mybatis.typeAliasesPackage=org.spring.springboot.domain
mybatis.mapperLocations=classpath:mapper/*.xml

## 端口
server.port=8081

4、新建demo\src\main\java\com\example\demo\mapper\UserMapper.java

package com.example.demo.mapper;

import com.example.demo.entity.User;
import org.apache.ibatis.annotations.Mapper;

import java.util.List;

Mapper
public interface UserMapper {

    public List<User> findUserByName(String userName);

    public List<User> ListUser();

    public List<User> queryPage(Integer startRows);

    public int getRowCount();

    public int insertUser(User user);

    public int delete(int userId);

    public int Update(User user);
}

5、新建demo\src\main\resources\mapper\UserMapper.xml

<?xml version = "1.0" encoding = "UTF-8"?>
<!DOCTYPE mapper PUBLIC
        "-//mybatis.org//DTD com.example.Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.demo.mapper.UserMapper">

    <resultMap id="result" type="com.example.demo.entity.User">
        <result property="userId" column="userId" />
        <result property="userDate" column="userDate" />
        <result property="userName" column="userName" />
        <result property="userAddress" column="userAddress"/>
    </resultMap>

    <select id="ListUser" resultMap="result">
        SELECT * FROM user
    </select>

    <select id="findUserByName" resultMap="result" parameterType="String">
        SELECT * FROM user
            where userName like concat(concat('%',#{userName}),'%')
            order by userId desc
    </select>

    <select id="queryPage" resultMap="result"  parameterType="Integer">
        select * from user
            order by userId desc
            limit #{startRows},5
    </select>

    <select id="getRowCount" resultType="Integer">
        select count(*) from user
    </select>

    <insert id="insertUser" parameterType="com.example.demo.entity.User">
        INSERT INTO user
        (
        userId,userDate,userName,userAddress
        )
        VALUES (
        #{userId},
        #{userDate, jdbcType=VARCHAR},
        #{userName, jdbcType=VARCHAR},
        #{userAddress, jdbcType=VARCHAR}
        )
    </insert>

    <delete id="delete" parameterType="int">
        delete from user where userId=#{userId}
    </delete>

    <update id="Update" parameterType="com.example.demo.entity.User">
        update user
            set user.userDate=#{userDate},user.userName=#{userName},user.userAddress=#{userAddress}
            where user.userId=#{userId}
    </update>
</mapper>

6、新建demo\src\main\java\com\example\demo\service\UserService.java

package com.example.demo.service;

import com.example.demo.entity.User;
import com.example.demo.mapper.UserMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;


Service
public class UserService {

    @Autowired
    private UserMapper userMapper;

    public List<User> findByName(String userName) {
        return userMapper.findUserByName(userName);
    }

    public List<User> queryPage(Integer startRows) {
        return userMapper.queryPage(startRows);
    }

    public int getRowCount() {
        return userMapper.getRowCount();
    }

    public User insertUser(User user) {
        userMapper.insertUser(user);
        return user;
    }

    public List<User> ListUser(){
        return userMapper.ListUser();
    }

    public int Update(User user){
        return userMapper.Update(user);
    }

    public int delete(int userId){
        return userMapper.delete(userId);
    }

}

7、新建demo\src\main\java\com\example\demo\controller\UserCtrl.java

package com.example.demo.controller;

import com.example.demo.entity.User;
import com.example.demo.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

RestController
public class UserCtrl {

    @Autowired
    private UserService userService;

    @RequestMapping(value = "/delete", method = RequestMethod.POST)
    public Integer delete(Integer userId) {
        System.out.println(userId);
        int result = userService.delete(userId);
        return result;
    }

    @RequestMapping(value = "/update", method = RequestMethod.POST)
    @ResponseBody
    public String update(User user) {
        int result = userService.Update(user);
        if (result >= 1) {
            return "修改成功";
        } else {
            return "修改失败";
        }

    }

    @RequestMapping(value = "/insert", method = RequestMethod.POST)
    public User insert(User user) {
        return userService.insertUser(user);
    }

    @RequestMapping("/ListUser")
    @ResponseBody
    public List<User> ListUser() {
        return userService.ListUser();
    }

    @RequestMapping("/ListByName")
    @ResponseBody
    public List<User> ListUserByName(String userName) {
        return userService.findByName(userName);
    }

    /**
     * 分页
     * @return
     */
    @RequestMapping(value="/page")
    @ResponseBody
    public List<User> page(Integer page){
        int pageNow = page == null ? 1 : page;
        int pageSize = 5;
        int startRows = pageSize*(pageNow-1);
        List<User> list = userService.queryPage(startRows);
        return list;
    }

    /**
     * rows
     * @return
     */
    @RequestMapping(value="/rows")
    @ResponseBody
    public int rows(){
        return userService.getRowCount();
    }
}

8、启动MySQL数据库，新建或执行如下表：

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;

  PRIMARY KEY (`userId`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 71 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;

-- ----------------------------

9、后端就写完了，整体结构如下：

10、run 'DemoApplication'启动项目，控制台没报错就用浏览器测试一下，在浏览器中输入http://localhost:8081/page?page=3 如果能出现如下字符串就??，已安装postman的可以每个方法都试一下：

前端开发环境搭建

1、win+R->cmd->进入项目目录依次执行命令：vue init webpack projectName、cd projectName、npm install、npm run dev如图所示：

2、打开浏览器输入：http://localhost:8080，效果如图：

3、用WebStorm打开项目：File->Open...->vue01(projectName)

4、Vue-cli项目结构如图：

前端开发过程

1、在项目根目录安装axios执行命令npm install axios，安装element ui 执行命令npm i element-ui -S
2、更新vue01\src\App.vue

<template>
  <div id="app">
    <el-row type="flex" justify="center">
      <el-col :xs="24" :sm="22" :md="20" :lg="20" :xl="18">
        <router-view/>
      </el-col>
    </el-row>
  </div>
</template>

<script>
    export default {
        name: 'App',
        data() {
            return {
            }
        },
        methods: {
        }
    }
</script>

<style>
  #app {
    font-family: 'Avenir', Helvetica, Arial, sans-serif;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    margin: 0px;
    padding: 0px;
  }
</style>

3、更新vue01\src\main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
import elementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import 'element-ui/lib/theme-chalk/display.css'

Vue.use(elementUI)

import axios from 'axios'
Vue.prototype.axios = axios

import qs from 'qs';
Vue.prototype.qs = qs;

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

4、更新vue01\src\components\HelloWorld.vue

<template>
  <div>
      <el-form :inline="true" class="demo-form-inline">
          <el-form-item>
            <el-input
              v-model="search"
              class="search_name"
              size="mini"
              placeholder="输入姓名查询">
            </el-input>
          </el-form-item>
          <el-form-item>
            <el-button
              type="text"
              @click="onSearch()"
              class="el-icon-search">查询
            </el-button>
          </el-form-item>
          <el-form-item>
            <el-button
              class="el-icon-refresh"
              type="text"
              @click="refreshData">刷新
            </el-button>
          </el-form-item>
          <el-form-item>
            <el-button
              class="el-icon-circle-plus-outline"
              type="text"
              @click="dialogVisible = true">添加

前后端整合

方式一：
在vue01\config\index.js文件中配置proxyTable{}，如下：

proxyTable: {
      '/': {
        target:'http://localhost:8081', // 你请求的第三方接口
        changeOrigin:true, // 在本地会创建一个虚拟服务端，然后发送请求的数据，并同时接收请求的数据，这样服务端和服务端进行数据的交互就不会有跨域问题
        pathRewrite:{  // 路径重写，
          '^/': ''  // 替换target中的请求地址
        }
      }
    },

方式二：
在vue-cli项目根目录执行命令npm run build，编译完成后将dist/static文件夹copy至springboot项目的src/main/resources/static目录下然后直接启动springboot项目就OK了。

实现效果
