Java Mysql更新用户密码

我正在尝试使用mybatis更新数据库密码：

update person 
   set name = #{name}, 
       address = #{address}, 
       phoneNumber = #{phoneNumber},
       balance = #{balance}, 
       password = #{password}, 
       id = #{new_id} 
 where id = #{id}

但是，出现以下异常：

org.apache.ibatis.exceptions.PersistenceException: 
### Error updating database.  Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'id' cannot be null
### The error may involve com.lsp.mybatis.PersonMapper.update-Inline
### The error occurred while setting parameters
### SQL: update person set name = ?, address = ?, phoneNumber = ?             ,balance = ?, password = ?, id = ? where id = ?
### Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Column 'id' cannot be null

我已指定要更新的用户id。为什么说“id不能为空”

有人能告诉我我做错了什么吗？

在查询中删除：

id={new\u id}

因此，查询将是：

update person 
   set name = #{name}, 
       address = #{address}, 
       phoneNumber = #{phoneNumber},
       balance = #{balance}, 
       password = #{password}
 where id = #{id}

您想更新

ID

还是

密码

？
