【我后续会发一个资源包,里面是所有代码,数据库表设计也有,大学生可以直接用,导入数据库运行,再导入后端项目和前端项目,再去网页运行就好了,效果图下面有】
1、考核要求:
- 数据库:MYSQL5.7+
- 后台技术:SpringBoot
- 前端技术:vue+elementui
- 代码简洁、有合理的注解,前面页面排版工整
2、考核注意事项:
1.运行sql脚本,创建数据库及书本表(根据我的实体类建表就可以了,整个项目可直接运行,跨域问题已处理,前后端的端口也已处理)
2.后台代码注意事项
a.Maven地址的修改(修改成你自己的);
b.依赖可能不在本地,需要联网重新下载;
c.jdbc.properties设置,数据库相关配置:数据库名/账号/密码,请修改成自己电脑所对应的账号和密码。
d.generatorConfig.xml设置:Ⅰ:修改classPathEntry配置,更换成本地maven仓库中mysql数据库jdbc驱动jar包的位置;Ⅱ:修改table配置表信息(tableName和domainObjectName),更换成考试中对应数据库表;Ⅲ:点击Edit Configurations...配置,添加Maven,输入命名:mybatis-gerenator:gerenate -e;
e.application.yml设置:数据库相关设置:数据库名/帐号/密码,请修改成自己电脑对应的帐号和密码
f.由于电脑tomcat以及jdk的安装位置不一样,请重新配置jdk和tomcat
g.以上步骤完成,先不要写任何代码,先将web项目发布至tomcat并启动,如果首页访问成功,表示web项目部署成功,可以开始编写后台代码了
3.前端代码注意事项:
1.vue项目框架已搭建完成,为减小源码大小,相关模块已删除,运行项目前,请先进入vue项目根目录,使用npm install命令下载相关模块(此步骤需要联网)
2.项目启动后无需添加路由或*.vue文件,运行后会直接跳转到BookList.vue,在此vue文件中添加相关功能即可
3.开动
generatorConfig.xml、jdbc.properties、application.yml这三个配置文件我就不展示了,有需要的下载我的资源包
数据库表建好之后→导入前端(可以把需要的依赖先下载,然后干自己的事)→导入后端(进行我上面所说的那些后端操作)→写完代码运行后端→在写前端代码(运行前端)
以下是后端的代码:

跨域问题处理:

@EnableAspectJAutoProxy
@SpringBootApplication
public class SpbootApplication {
public static void main(String[] args) {
SpringApplication.run(SpbootApplication.class, args);
}
}
以下是前端的代码:
前端接收后端的请求路径,src下面api下面的action.js
/**
* 对后台请求的地址的封装,URL格式如下:
* 模块名_实体名_操作
*/
export default {
//服务器
'SERVER': 'http://localhost:8080/spboot',
'ADD':'book/addBook',
'ALL':'book/queryAll',
//获得请求的完整地址,用于mockjs测试时使用
'getFullPath': k => {
return this.SERVER + this[k];
}
}
前端src下面的router下面的index.js文章来源:https://www.toymoban.com/news/detail-445555.html
import Vue from 'vue'
import Router from 'vue-router'
import BookList from '@/views/BookList'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'BookList',
component: BookList
}
]
})

以上就是今天的分享!!!
刚好有大学生找我帮忙写这个项目,我想可以与大家分享一下代码,有其他同行需要代码的也可以找我。感谢支持!
到了这里,关于Springboot快速开发-书本信息管理系统(项目源码)的文章就介绍完了。如果您还想了解更多内容,请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章,希望大家以后多多支持TOY模板网!
