WinXP 和 Mac OS X 中的 MySql
我面临着这个奇怪的问题。 我在我的 Win XP 机器上编码,然后将所有代码移至 Mac OS X 机器。 使用 XP 机器上的 jar 运行它。 我正在用 java 编码并使用 hibernate 进行数据库处理。
不知何故,我无法插入一行,而键是使用增量生成器类生成的。 我也在 Mac 上尝试了本机但同样的错误。
这是调试模式。 现在,我知道该错误是密钥违规,但在 WinXP 中不会发生同样的情况。 我在运行代码之前截断数据库。 我认为它们是 Mac 中的一些生成器类依赖项。 或者其他一些罐子?
以下是一些具体信息:
- Mac OS X 10.5 (x86_64)
- MYSQL 5.1.35 社区服务器
- mysql-connector-java-5.1.7-bin.jar JDBC 驱动程序
- Java(TM) 2 运行时环境,标准版(内部版本 1.5.0_16- b06-284)
- Java HotSpot(TM) 客户端 VM(版本 1.5.0_16-133,混合模式,共享)
请告知

org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update
I am facing this bizarre problem.
I am coding on my machine in Win XP and then moving all the code to Mac OS X machine.
Running it using the jars from XP machine.
I am coding in java and using hibernate for database processing.
Somehow I am not able to insert one row, while the keys are generated using the increment generator class. I also tried native but same error on Mac.
here is the debug mode. Now, I know the error as a key violation, but the same doesn't occur in WinXP. I truncate my database before running code. I think their is some generator class dependency in Mac. Or some other jars?
And here are some specifics:
- Mac OS X 10.5 (x86_64)
- MYSQL 5.1.35 Community Server
- mysql-connector-java-5.1.7-bin.jar JDBC driver
- Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b06-284)
- Java HotSpot(TM) Client VM (build 1.5.0_16-133, mixed mode, sharing)
please advise

没什么可继续的,但这就是我可以理解的:
现在您可以执行以下操作:
想一想:Pagedatecount 实体不是缺少日期列吗? 它似乎没有被插入。
There is very little to go on, but this is what I can make of it:
Now there is a few things that you can do:
AUTO_FLUSH
mode is working correctly, so the session is flushed whenever a new entity needs to be inserted just before a query is made on this table. To make this work as intended, you'll have to make sure that Hibernate is aware of transactions that are started.Come to think of it: Isn't the Pagedatecount entity missing a date column? It is not being inserted it seems.
我遇到了同样的问题。 不知道你已经解决了没有。 无论如何,就我而言,这是 MySQL 如何创建表并执行表名比较的问题。 在 MacOsX 上,我必须将“lower_case_table_names”MySQL 变量设置为 1(默认情况下为 0),这是使用 InnoDB 时的建议值。 这解决了我的问题(和你一样,Hibernate 似乎没有获取自动生成的 id)。
希望这可能有所帮助,
里卡多.
I run into the same problem. Don't know if you have already solved it. Anyway, in my case it was a problem of how MySQL creates tables and performs table names comparison. On MacOsX I had to set the "lower_case_table_names" MySQL variables to 1 (by default it was 0), which is the suggested value when using InnoDB. And this solved my problem (which, as you, was that it seemed Hibernate was not picking up the autogenerated ids).
Hopes this might help,
Riccardo.
