# mybatis-hello
mybatis demo

very simple demo,but you can learn how does the mybatis work

in com.Test#main  shows two way to use mybatis
1. normal way, xml configuration
2. no xml. all is java code

mybatis-config.xml mybatis config
CourseMapper.xml  table course mappered to sql and entity.Course
mapper.CourseMapper  use CourseMapper.xml to mapper sql
entity.Course     table course entity


table course
id(int)  name(varchar) takeTime(int)  courseNum(varchar)


after add slf4j + logback, there are sql log in the output


mybatis 多对多查询demo

student学生表  id name age stuNum学生号
sc 选课表      id stuNum courseNum
course 课程表  id name takeTime学时 courseNum课程号
主要是看CourseMapper.xml的getStu查询的resultMap
