SQL BUG - java.sql.SQLSyntaxErrorException -已解决

• 在写完了控制层，服务层和mapper层和sql语句后，启动服务器爆了以下错误：

### Error querying database.  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 'WHERe ADMIN_NAME = 'admin' and ADMIN_PWD = 'admin'' at line 1
### The error may exist in file [E:workcodesshoptargetshop-1.0-SNAPSHOTWEB-INFclassesmapperAdminMapper.xml]
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### SQL: select admin_id, admin_name, admin_pwd, admin_realname, admin_email         from t_admin;                WHERe ADMIN_NAME = ? and ADMIN_PWD = ?
### 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 'WHERe ADMIN_NAME = 'admin' and ADMIN_PWD = 'admin'' at line 1
; 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 'WHERe ADMIN_NAME = 'admin' and ADMIN_PWD = 'admin'' at line 1] with root 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 'WHERe ADMIN_NAME = 'admin' and ADMIN_PWD = 'admin'' at lin

提示我sql语句语法出错了，

 Cause: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax;

并告诉我在这附近：

near 'WHERe ADMIN_NAME = 'admin' and ADMIN_PWD = 'admin'' at line 1

仔细检查后发现：在我的sql标签中，我在结束时候习惯性的加了分号 “;” ，在去点该分号后，不再报错。

    
        select admin_id, admin_name, admin_pwd, admin_realname, admin_email from t_admin;
    

    
        
        
            ADMIN_NAME = #{adminName} and ADMIN_PWD = #{adminPwd}
        
    

在后面查询中我用到了这个片段，拼接后多出来的分号导致语法错误，无法顺利执行，非常低级的错误，记录下来供反思。
