一、准备条件

前台

后台

二、数据库设计

建议不要导入，导入有乱码的风险；新建查询运行下面代码更快捷。

三、导入前端项目

导入后使用命令行打开黑窗口，测试一下有没有npm -v环境

如果出现命令无效，就使用管理员身份打开黑窗口

npm install

npm run dev

四、后台项目导入步骤及编码

如果忘记电脑的maven在那个盘，使用 mvn -version 查找本机 maven 地址编辑

生成mapper类中添加注解 @Repository

添加模糊查询方法

编写SQL

编写service 编辑

编写实现类

创建controller类

controller层代码提供

五、前端编码

action.js

index.js

编写页面，BookList.vue

六、前后台代码提供

后台：

application.yml

jdbc.properties

generatorConfig.xml

BookMapper

BookMapper.xml

BookService

BookServiceImpl

BookController

前台：

action.js

router-index.js

BookList.vue

一、准备条件

小编事先准备了一份前台、后台的基本架构的代码，如果你手上有现有的那就按照小编的步骤来就ok，没有就需要创建spa项目、后台项目。

前台：

后台：

二、数据库设计

建议不要导入，导入有乱码的风险；新建查询运行下面代码更快捷。

create database if not exists bookshop default charset utf8 collate utf8_general_ci;

use bookshop;

create table t_book(
   id int not null auto_increment primary key comment '书本编号',
   bookname varchar(50) not null comment '书本名称',
   price float default 0 comment '书本价格',
   booktype varchar(20) comment '书本类型'
) comment '书本信息表';
insert into t_book(bookname,price,booktype) values
('三国演义',110,'战争'),
('西游记',120,'神话'),
('红楼梦',130,'古典');

三、导入前端项目

导入手上有的，没有就创建，至于怎么创建，小编就不详讲了。

怎么导入嘞，你找到项目用鼠标拖进去，也可以右键找到项目地址导入。

导入后使用命令行打开黑窗口，测试一下有没有npm -v环境

如果出现命令无效，就使用管理员身份打开黑窗口

跳转项目所在盘，将路径复制进去，再输入npm -v

npm install

npm run dev

或者在HBuilder X中，启动前端看一下页面能不能展示出来

前端页面可以展示出来，准备后台编码

四、后台项目导入步骤及编码

打开IDEA

找到，选中

选中maven，finish下一步

如果忘记电脑的maven在那个盘，使用 mvn -version 查找本机 maven 地址

项目导入idea中，第一步-->Settings-->maven-->配置maven

看 application.yml 该改的改一改，数据库名称什么的

jdbc.properties 也改巴改巴，总之改为你电脑的数据库的密码或名称就ok

generatorConfig.xml 更改指定数据库jdbc驱动jar包的位置，你的jar放哪嘞，应该忘记了吧，问题不大

mysql-connector-java\5.1.44\  拷贝它，在本机目录中搜索

亦或者，打开更改配置maven的地址

手动复制地址过来后，检查一下Javabean生成位置等，就可以编辑生成表了

怎么生成呢，小编目前知道的方式有两种方式，教大家一个简单快捷的。

BUILD SUCCESS ok了

生成mapper类中添加注解 @Repository

添加模糊查询方法

编写SQL

<select id="query" resultType="com.zking.spboot.model.Book">
    select <include refid="Base_Column_List"/> from t_book where 1=1
    <if test="null!=bookname and ''!=bookname">
      and bookname like concat('%',#{bookname},'%')
    </if>
  </select>

编写service

记得将Mapper层的@Repository 注解删掉，service不用注解

编写实现类

添加注解@Service

创建controller类

controller层代码提供

package com.zking.spboot.controller;

import com.zking.spboot.model.Book;
import com.zking.spboot.service.BookService;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * @author 小坤
 * @create 2022-11-18-19:19
 */
@RestController
@RequestMapping("/book")
public class BookController {

    @Autowired
    private BookService bookService;

    @RequestMapping("/query")
    public JsonResponseBody<?> query(Book book){
        List<Book> books=bookService.query(book);
        return new JsonResponseBody<>(200,"ok",books);
    }

    @RequestMapping("/add")
    public JsonResponseBody<?> add(Book book){
        bookService.insert(book);
        return new JsonResponseBody<>();
    }

    @Data
    @AllArgsConstructor
    @NoArgsConstructor
    class JsonResponseBody<T>{
        private int code=200;
        private String msg="ok";
        private T data;
    }

}

运行测试一波

五、前端编码

先把这边编写好

action.js

index.js

编写页面，BookList.vue

最终效果，想要展示成这样，我们拜读element ui 官网，找到自己需要的样式拷贝下来，改巴改巴

表单form，搜索栏

数据表格 table 随便找一个，小编就用第一个最丑的基础表格

对话框自定义内容

表单校验
