最近几天几天做项目用到了Spring Data JPA,确实是个好东西,省了很多力气.但是由于刚开始用,也遇到不少头疼的问题,如下,调用JpaRepository接口的save方法保存一个对象到数据库中的时候出错: ERROR: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'portal.hibernate_sequence' doesn't exist,  wqee 对这个问题可以说是几经磨难,一直想不通为何…

将一模一样的项目从win迁移到到linux上报错: 一开始还是以为是linux不能识别hql语句,查找资料发现是因为Liunx服务器上mysql是区分大小写的,而本地是不区分的如:代码是这样写的 @Entity@Table(name = "users") 数据库建的表名称是Users,那么就会出现以上异常. 详细介绍请查看全文:https://cnblogs.com/qianzf/ 原文博客的链接地址:https://cnblogs.com/qzf/…

这个问题主要是说,你查找的表不存在,但是,事实上我这个表示存在的,会产生这个问题的原因是,我这个表的大小写拼写方式跟sql语句中的大小写不一样,这时就要设置数据库不区分大小写 找到mysql的配置文件,服务器选用的是centos7 命令: cat   /etc/my.cnf   查看配置文件是否存在,如果存在就对其进行编辑 vi     /etc/my.cnf   编辑文件 输入 a/i/o   进行编辑 添加属性 lower_case_table_names=0(0:区分大小写,1:不区分大小…

先说结论: 因为在表设计中有一个商品描述字段被设置为desc,但desc是mysql中的关键字,如select id,name,desc,price from product;这条sql语句在查询时的sql语句解析会和期望的不一样,导致出现问题.因为平时在写java代码的时候很自然的会将描述变量设置为desc,在设计表字段时也没有多想,忘记和忽略了desc为mysql中的关键字,酿成此问题. 排查思路: 一开始怀疑是因为sql过长,删了一部分,成功了,加上又失败了,而且一直提示在price那里只…
