报告 sql 语法错误，
把生成的代码，贴到sqlyog里运行，也提升错误
原因是 sql里用了sql的关键字，如lock。
from tbl_admin
where id = 1‘ at line 3
### The error may exist in file [D:\OneDrive\project\activiti\target\classes\mapper\AdminMapper.xml]
### The error may involve cn.taotao.dao.AdminMapper.selectByPrimaryKey-Inline
### The error occurred while setting parameters
### SQL: select id, username, password, email, lock, birth from tbl_admin where id = ?
### Cause: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘lock, birth
from tbl_admin
where id = 1‘ at line 3
; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘lock, birth
错误中已经提到 near ‘ lock ,birth, from tbl_admin where id =1 ‘.....
这里的错误，原因是 lock 是关键字，改为其他即可。弄了半个下午
