问为什么MybatisPlus更改变量名导致的查询错误？

@TableName(value = "student")
@Data
public class Student implements Serializable {

    @TableId(type = IdType.AUTO)
    @TableField(value = "stuId")
    private Integer stuid;
}

org.springframework.jdbc.BadSqlGrammarException: 
### Error querying database.  Cause: java.sql.SQLSyntaxErrorException: Unknown column 'stu_id' in 'field list'
### The error may exist in com/example/mapper/StudentMapper.java (best guess)
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### SQL: SELECT stu_id,stuName FROM student WHERE stu_id=?
### Cause: java.sql.SQLSyntaxErrorException: Unknown column 'stu_id' in 'field list'
; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Unknown column 'stu_id' in 'field list'但是我的表中只有stui
