1.后端：
-
设计数据库，根据需求，分析数据库，建库建表（库：db_spring）
day08-1.png
day08-2.png
-
建立web模块类型的maven项目
手动创建src,resources,test-java目录
建立package,entity,dao,service,controller

- entity实体类
SysUser类、Course类、CourseVO类 - dao接口，增加自定义的复杂关联查询（注解）
SysDAO类、CourseDAO类、BaseDAO类 - service接口，注入dao，调用相应方法
CourseService类、CourseServiceImpl类 - 对service做单元测试
CourseServiceImplTest - controller,使用RESTful风格请求，完成控制层
CourseController类、web.xml - 用postman对controller进行接口测试，杜绝一切404和500
