问题描述
class SomeService {
static transactional = true
def someMethod(){
...
a.save()
....
b.save()
....
c.save()
....
等...
}
}
我想知道事务性方法是否成功,我不想检查每个域对象中的错误属性因为逻辑涉及许多域类,所以很难。
a.save(failOnError:true)
b.save(failOnError:true)
c.save(failOnError:true)
d .save(failOnError:true)
我假设你想要的服务是抛出异常单域保存错误,并在这种情况下回滚事务。
I have something like this:
class SomeService {
static transactional = true
def someMethod(){
...
a.save()
....
b.save()
....
c.save()
....
etc...
}
}
I want to know if the transactional method was successful or not, I don't want to check the error property in each domain object because the logic involve many domain classes and it would be difficult.
解决方案
Use
a.save(failOnError: true)
b.save(failOnError: true)
c.save(failOnError: true)
d.save(failOnError: true)
I'm assuming what you want is the service to throw exception on error of a single domain save, and rollback the transaction in such cases.
