MyBatis删除数据

一般删除(delete)，通过主键(id)删除 DeptMapper

    
    
     delete from Dept where id=#{id}
    

Test

 //测试删除
    @Test
    public void deleteDept(){
        try {
            //Dept dept = new Dept();
            //dept.setId(17);
            session.update("DEPT.deleteDept",17);
            session.commit();//正常提交
        } catch (Exception e) {
            e.printStackTrace();
            session.rollback();//异常回滚
        }
    }
