Instrucciones de uso

本项目使用maven进行管理，详细安装教程自行百度
1.  需下载mysql图形化管理工具(例如Navicat)，新建数据库library，右键数据库-->运行项目中的library.sql脚本
2.  打开项目(idea或eclipse皆可，但需配置好maven环境)，打开src/main/resources/application.yml，将数据库的username和password修改成你自己的mysql的用户名和密码
3.  找到BookmanagerApplication类运行main方法，打开浏览器，网址栏输入localhost:8080访问系统

4.  如果不想用IDE打开项目而是想直接运行的朋友们，在目录下打开cmd键入mvn package命令，然后在target/目录下会生成对应的jar包，在cmd用“java -jar jar包名”运行即可

注意事项

1.  高版本mysql在登录时可能会报空指针错误，出现问题的建议安装并使用mysql5.7版本
