myBatis映射Map返回的全是大写

myBatis映射Map返回的全是大写

解决方法
在查询的字段后加别名

user_id as “userId”
注意:别名必须加双引号

    SELECT A.SELL_PRICE as "price", B.USER_ID as "userId"
      FROM QLYY_SELL_AUCTION_RECORD A, QLYY_SELL_APPLY B
     WHERE A.SELL_PRICE = (SELECT MAX(SELL_PRICE)
                             FROM QLYY_SELL_AUCTION_RECORD
                            WHERE SELL_PROGRAM_ID = #{programId})
       AND A.SELL_PROGRAM_ID = #{programId}
       AND B.APPLY_CODE = A.SELL_USER
