踩坑系列—mybatis查詢報錯java.lang.IndexOutOfBoundsException

sql單獨執行正确，但是mybatis查詢報錯，部分錯誤資訊如下：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:

###Error querying database. Cause: java.lang.IndexOutOfBoundsException: Index: 6, Size: 6

###The error may involve com.xxx.persistence.mapper.XXXMapper.countxxxQty

###The error occurred while handling results

原因：

mapper中查詢結果resultMap對應的DoxxxDto使用了

lombok注解，使用有誤導緻的

。報錯時的注解：

@Data

@Builder

public class DoxxxDto{

private xxx1;

private xxx2;

private xxx3;

private xxx4;

private xxx5;

private xxx6;

private xxx7;

}

沒有構造函數，将查詢結果轉換成javebean的時候出了問題，報錯中的6是因為查詢了6列。加上構造函數的注解即可。如下：

@Data

@Builder

@NoArgsConstructor

@AllArgsConstructor

public class DoxxxDto{

private xxx1;

private xxx2;

private xxx3;

private xxx4;

private xxx5;

private xxx6;

private xxx7;

}
