英文:
using spring transactionManager with Hibernate after transaction committed only one repository of two is actually being committed
问题
我有一个带有@Transactional注解的方法，它会更改两个不相关存储库中两个实体的状态。
大致如下：
@Transactional
public void foo() {
A a = repoA.findById(1);
a.setState(s1);
B b = repoB.findById(1);
b.setState(s2);
// （虽然多余，但我也执行 repoA.save(a); 和 repoB.save(b);）
}
我还有一个事务性方法bar，它调用foo方法并发布一个事件，该事件会被TransactionalEventListener捕获，如下所示：
@Transactional
public void bar() {
foo();
applicationEventPublisher.publishEvent(new AppEvent(123));
}
以及
@Component
public class MyApplicationEventListener {
@TransactionalEventListener
public void handleAfterCommit(AppEvent appEvent){
//做些事情;
}
}
现在的问题是，当调用handleAfterCommit方法时，80%的情况下只有(A a)被提交，而(B b)失去了它的更改。
我需要帮助来理解这里发生了什么，我尝试过调试和探索TransactionAspectSupport.currentTransactionStatus()，但没有找到任何见解。
谢谢，

英文:
I have a @Transactional method that changes the state of two entities of different, not related, repositories.
something like this:
@Transactional
public void foo() {
A a = repoA.findById(1);
a.setState(s1);
B b = repoB.findById(1);
b.setState(s2);
// (and I also do repoA.save(a); and repoB.save(b); although it is redundant)
}
I also have a transactional method bar that calls foo and publishes an event that is being caught by a TransactionalEventListener like this:
@Transactional
public void bar() {
foo();
applicationEventPublisher.publishEvent(new AppEvent(123));
}
and
@Component
public class MyApplicationEventListener {
@TransactionalEventListener
public void handleAfterCommit(AppEvent appEvent){
//do something;
}
}
Now the issue is that in 80% of the time when handleAfterCommit method is invoked, only (A a ) is being committed but (B b) is losing its changes.
I need help to understand what is going on here, I tried to debug and explore the
TransactionAspectSupport.currentTransactionStatus() but didn't find any insights.
Thanks,

我找到了问题，我们正在使用自定义的AttributeConverter，而且我们没有为相关的Java对象实现Equals方法，这导致每次选择性能检查失败，并进行完整的更新（覆盖其间已更改的值）
谢谢。
英文:
I found the issue, we are using a custom AttributeConverter and we didnt implement Equals for the relevant javav object, this caused every dirty check on select to fail and do a full update (overriding values that meanwhile have been changed)
Thanks
