@交易注释

问题描述

$ b

• 将@Transactional注释添加到整个类中
  
• 为每一种方法添加@Transactional注解？

使用spring和Hibernate？

@Transactional 所有方法都是事务性的。
如果您不这样做，您可以注释为只有你想要的那些方法。另外，您可以为每个方法指定不同的属性，例如 isolation ， propagation ， timeout ，...

另外，看看这个问题，这可能与它重复：

is there any difference between:

• add "@Transactional" annotation to whole class
• add for every single method "@Transactional" annotation ?

Using spring and Hibernate ?

解决方案

Basically, if you annotate the class with @Transactional all methods will be transactional.If you don't, you can annnotate as @Transactional only those methods you want to. Additionally, you can specify different attributes for each method, like isolation, propagation, timeout, ...

Also, take a look at this question, this is a possible duplicate of it: Hibernate transaction annotations in source — difference between class and method level use?
