Unknown column 'brrow0_.book_id' in 'field list'

访问数据库数据错误

一定要看查询的SQL语句

Hibernate: 
    select
        brrow0_.id as id1_2_,
        brrow0_.book_id as book_id2_2_,
        brrow0_.brrow_date as brrow_da3_2_,
        brrow0_.return_date as return_d4_2_,
        brrow0_.stu_id as stu_id5_2_ 
    from
        brrow brrow0_

error:

java.sql.SQLSyntaxErrorException: Unknown column 'brrow0_.book_id' in 'field list'

然后看自己的brrow表 是 bookId ，entity里面写的实体类也是bookId,但是Hibernate: 会把驼峰转化为book_id，

把brrow表 下面的 bookId 改为 book_id，就ok。
