Hibernate mysql innodb

Question

我想强制hibernate使用innodb。

因此，为了拥有innodb，我更改了“hibernate.dialect”，但是我可以连接到mysql，但是当我执行某些事务时，出现以下错误：

org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rol lbackOnly at org.springframework.orm.jpa.JpaTransactionManager.doCommit(JpaTransactionManager.java:465) at org.springframework.transaction.support.AbstractPlatformTransactionManager.processCommit(AbstractPlatformTransactionManager.java:709) at org.springframework.transaction.support.AbstractPlatformTransactionManager.commit(AbstractPlatformTransactionManager.java:678) at org.springframework.transaction.interceptor.TransactionAspectSupport.commitTransactionAfterReturning(TransactionAspectSupport.java:321) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:116) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at $Proxy46.deleteAsset(Unknown Source)

这是我的persistence.xml：

你有什么主意吗 ？

Answer 1

Hibernate对于表是Inno，MyISAM还是其他存储引擎没有发言权-这是在MySQL方面决定的。服务器配置中有默认值，您可以在创建表时覆盖它们。

差异不会给您带来跟踪-当您在MyISAM表上使用事务时，所有操作都会发生，因为您没有事务。一切都成功了，但是没有隔离，没有回滚。

根据@shipmaster，您的跟踪记录表明您有潜在的问题，这可能与您选择的方言无关。查看日志，或将Spring的源代码附加到项目中并进行跟踪。
