Spring Boot+Vue 前后端分离项目架构

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 {
    //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 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 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 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

2、数据列表视图 views/table.vue

3、新增视图文件 views/addBook.vue

4、编辑或修改视图文件 views/edit.vue

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')
