Spring Boot+Vue 前后端分离项目架构

项目流程：

1. SpringBoot 后端项目

1、新建一个 SpringBoot 工程，并添加项目开发过程中需要的相关依赖；

2、数据库新建 book 数据表；

-- ----------------------------
-- Table structure for book
-- ----------------------------
DROP TABLE IF EXISTS `book`;
CREATE TABLE `book`  (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `title` varchar(55) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `publish` varchar(55) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `authors` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `createTime` datetime(0) NOT NULL DEFAULT CURRENT_TIMESTAMP(0),
  `updateTime` datetime(0) NOT NULL DEFAULT CURRENT_TIMESTAMP(0) ON UPDATE CURRENT_TIMESTAMP(0),
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 14 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of book
-- ----------------------------
INSERT INTO `book` VALUES (2, '数据结构', '浙江出版社', '严威', '2022-03-18 14:38:22', '2022-03-18 14:38:25');
INSERT INTO `book` VALUES (5, '计算机组成原理', '机械工业出版社', '唐朔飞', '2022-03-14 14:38:28', '2022-03-15 14:38:36');
INSERT INTO `book` VALUES (6, '机器学习', '人民邮电出版社', '周志华', '2022-03-16 14:38:41', '2022-03-16 14:38:45');
INSERT INTO `book` VALUES (7, '图论及其应用', '科学技术出版社', '徐俊明', '2022-03-03 14:38:49', '2022-03-18 18:33:57');
INSERT INTO `book` VALUES (8, '推荐系统开发实战', '电子工业出版社', '高团阳', '2022-03-14 14:38:57', '2022-03-16 14:39:02');
INSERT INTO `book` VALUES (9, '大数据导论', '机械工业出版社', '曾诚', '2022-03-10 14:39:06', '2022-03-12 14:39:09');
INSERT INTO `book` VALUES (13, 'Java从零基础到实战', '中国工信出版集团', '宁楠', '2022-03-18 17:05:18', '2022-03-18 17:05:18');

3、application.yml 配置数据源和项目启动的端口号；

# 修改服务启动的端口
server:
  port: 8181
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/book?useUnicode=true&characterEncoding=UTF-8
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
# 配置日志，打印执行的sql语句
mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

项目整体的目录结构如下：

4、创建实体类 Book.java；

@AllArgsConstructor
@NoArgsConstructor
@Data
@TableName(value = "book")
public class Book {
    @TableId(type = IdType.AUTO)
    private Long id;
    private String title;
    private String publish;
    private String authors;

    @TableField(value = "createTime", fill = FieldFill.INSERT)
    private Date createTime;
    @TableField(value = "updateTime", fill = FieldFill.INSERT_UPDATE)
    private Date updateTime;
}

5、添加 MyBatis Plus 自动填充的处理器 config/DataHandler.java；

import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
public class DataHandler implements MetaObjectHandler{
    //插入时的填充策略
    @Override
    public void insertFill(MetaObject metaObject) {
        this.setFieldValByName("createTime", new Date(), metaObject);
        this.setFieldValByName("updateTime", new Date(), metaObject);
    }
    //更新时的填充策略
    @Override
    public void updateFill(MetaObject metaObject) {
        this.setFieldValByName("updateTime", new Date(), metaObject);
    }
}

6、持久化层 mapper/BookMapper.java；

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.trainingl.entity.Book;
import org.springframework.stereotype.Repository;

@Repository  //持久层注解
public interface BookMapper extends BaseMapper<Book> {
    //所有的CRUD操作都已经编写好了
}

7、服务层 service；

service/BookService.java

import com.trainingl.entity.Book;
import java.util.List;

//数据的增删改查接口
public interface BookService {
    public List<Book> findAll();
    public Book findById(Long id);
    public int insert(Book book);
    public int deleteById(Long id);
    public int updateById(Book book);
}

service/Impl/BookServiceImpl.java

import com.trainingl.entity.Book;
import com.trainingl.mapper.BookMapper;
import com.trainingl.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class BookServiceImpl implements BookService {
    @Autowired
    private BookMapper bookMapper;
    @Override
    public List<Book> findAll() {
        //查询搜索记录
        return bookMapper.selectList(null);
    }

    @Override
    public Book findById(Long id) {
        return bookMapper.selectById(id);
    }

    @Override
    public int insert(Book book) {
        return bookMapper.insert(book);
    }

    @Override
    public int deleteById(Long id) {
        return bookMapper.deleteById(id);
    }

    @Override
    public int updateById(Book book) {
        return bookMapper.updateById(book);
    }
}

8、控制层 Controller；

controller/BookController.java

import com.trainingl.entity.Book;
import com.trainingl.service.BookService;
import org.apache.ibatis.annotations.Param;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

@RestController
@CrossOrigin  //跨域注解
public class BookController {
    @Autowired
    private BookService bookService;

    @RequestMapping("/booklist")
    public List<Book> booklist(){
        return bookService.findAll();
    }

    @RequestMapping("/addbook")
    public int addbook(@RequestBody Book book){
        return bookService.insert(book);
    }

    @DeleteMapping("/deleteById/{id}")
    public int deleteById(@PathVariable("id") Long id){
        Integer result = 0;
        result = bookService.deleteById(id);
        //删除成功则返回受影响的行数
        return result;
    }

    @GetMapping("/findById/{id}")
    public Book findById(@PathVariable("id") Long id){
        return bookService.findById(id);
    }

    @PutMapping("/updateById")
    public int updateById(@RequestBody Book book){
        //返回修改的条数
        return bookService.updateById(book);
    }

}

2. Vue 前端项目

1、主页面 App.vue

<template>
    <div id="app">
        <router-view/>
    </div>
</template>

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

    }
</script>

2、数据列表视图 views/table.vue

<template>
    <div>
        <el-table
                :data="tableData"
                border
                style="width: 70%">
            <el-table-column
                    fixed
                    prop="id"
                    label="编号"
                    width="80">
            </el-table-column>
            <el-table-column
                    prop="title"
                    label="书籍名称"
                    width="160">
            </el-table-column>
            <el-table-column
                    prop="publish"
                    label="出版社"
                    width="150">
            </el-table-column>
            <el-table-column
                    prop="authors"
                    label="作者"
                    width="120">
            </el-table-column>
            <el-table-column
                    prop="createTime"
                    label="创建时间"
                    width="150">
            </el-table-column>
            <el-table-column
                    prop="updateTime"
                    label="修改时间"
                    width="150">
            </el-table-column>
            <el-table-column
                    fixed="right"
                    label="操作"
                    width="150">
                <template slot-scope="scope">
                    <el-button @click="del(scope.row)" type="danger" size="small">删除</el-button>

    </div>
</template>

<script>
    export default {
        name: "table",
        methods: {
            addBook(){
                this.$router.push("/addbook")
            },
            del(row) {
                let _this = this;

                this.$confirm('此操作将永久删除该记录, 是否继续?', '提示', {
                    confirmButtonText: '确定',
                    cancelButtonText: '取消',
                    type: 'warning'
                }).then(() => {
                    this.$axios.delete("http://localhost:8181/deleteById/" + row.id).then(function (response) {
                        if (response.data == 1) {
                            //刷新页面
                            location.reload();
                        } else {
                            _this.$message({
                                showClose: true,
                                message: '删除信息失败!',
                                type: 'danger'
                            });
                        }
                    })

            }
        },

        data() {
            return {
                tableData: []
            }
        },

                    ]
                }
            };
        },
        methods: {
            submitForm(formName) {
                let _this = this;
                this.$refs[formName].validate((valid) => {

            }
        }
    }
</script>

<style scoped>
</style>

4、编辑或修改视图文件 views/edit.vue

<template>
    <div>
        <h2 style="padding-left: 200px">修改图书信息</h2>
        <el-form :model="ruleForm" style="width: 500px;" status-icon :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">

        data() {
            var checkAuthor = (rule, value, callback) => {
                if (value === '') {
                    callback(new Error('请输入作者信息'));
                } else {
                    callback();
                }

                    publish: '',
                    authors: '',
                    createTime: '',
                    updateTime: ''
                },
                rules: {
                    title: [
                        { validator: validateTitle, trigger: 'blur' }
                    ],
                    publish: [
                        { validator: validatePublish, trigger: 'blur' }
                    ],
                    authors: [
                        { validator: checkAuthor, trigger: 'blur' }
                    ]
                }
            };
        },
        methods: {
            submitForm(formName) {
                let _this = this;
                this.$refs[formName].validate((valid) => {
                    if (valid) {
                        this.$axios.put("http://localhost:8181/updateById", _this.ruleForm).then(function (response) {
                            if(response.data === 1){
                                //跳转到表格页面
                                _this.$router.push('/table')
                            }
                        })
                    } else {
                        console.log('error submit!!');
                        return false;
                    }
                });
            },
            resetForm(formName) {
                this.$refs[formName].resetFields();
            }
        },
        mounted(){
            let _this = this;
            this.$axios.get("http://localhost:8181/findById/" + this.$route.query.id).then(function (response) {
                _this.ruleForm = response.data;
            });
        }
    }
</script>

<style scoped>
</style>

5、路由文件 router.js

import Vue from 'vue'

//1.导入路由依赖，安装 vue-router组件后系统带有的依赖
import VueRouter from 'vue-router'

//2.导入两个页面
import Login from "@/views/login";
import Second from "@/views/Second";
import Table from "@/views/table";
import AddBook from "@/views/addBook";
import Edit from "@/views/edit";

// 3.使用路由
Vue.use(VueRouter);

//4.创建路由对象，new VueRouter为上面import设置的名称
const router = new VueRouter({
    //没有history，访问URL会有#
    mode: "history",
    routes: [
        {
            path:"/login",
            component: Login
        },
        {
            path:"/second",
            component: Second
        },
        {
            path:"/table",
            component: Table
        },
        {
            path:"/addbook",
            component: AddBook
        },
        {
            path:"/edit",
            component: Edit
        },
    ]
});
export default router;

6、组件的全局配置 main.js

import Vue from 'vue'
import App from './App.vue'
import router from "./router/index"

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

import axios from "axios"
import qstring from "querystring"

// Vue 全局Vue对象，prototype原型设置全局属性
Vue.prototype.$axios = axios
Vue.prototype.$qstring=qstring

Vue.config.productionTip = false;
Vue.use(ElementUI);

new Vue({
    router,
    render: h => h(App),
}).$mount('#app')
