HowTo extend Spring Annotation @Transactional

由 廉价感情. 提交于 2019-12-10 13:13:03
问题 I have to use 3 different transaction managers in my webapp. So I wrote my own Annotation according to the Spring reference (Section 10.5.6.3 Custom shortcut annotations). One annotation (for using one specific transactionmanager) looks like this: import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; import org.springframework.transaction.annotation.Transactional; @Target({ElementType

Transactionally writing files in Node.js

由 为君一笑 提交于 2019-12-10 03:24:27
问题 I have a Node.js application that stores some configuration data in a file. If you change some settings, the configuration file is written to disk. At the moment, I am using a simple fs.writeFile . Now my question is: What happens when Node.js crashes while the file is being written? Is there the chance to have a corrupt file on disk? Or does Node.js guarantee that the file is written in an atomic way, so that either the old or the new version is valid? If not, how could I implement such a

Spring Transactional annotation, isolation not working for READ_UNCOMMITTED

由 眉间皱痕 提交于 2019-12-08 21:19:24
I have a method in Java which is wrapped by a spring Transactional annotation. I have 2 operations inside, one is delete , another one is insert . My insertion statement have to rely on the first operation (which is the delete ), but now because of the first operation is not committed yet, my insertion fail (unique constraint). But this is funny that, usually within the same transaction, I should be able to read/see the uncommited operation in the same transaction (my old proprietary framework are able to do that), but this is not happening for my scenario, the second insertion still fail

In my SchoolManagementService class I have a method deleteStudents(List) which I have marked

What is interface-based proxying?

由 会有一股神秘感。 提交于 2019-12-07 06:56:36
问题 I was reading this regarding to where to place Transactional(interface vs implementation): The Spring team's recommendation is that you only annotate concrete classes with the @Transactional annotation, as opposed to annotating interfaces. You certainly can place the @Transactional annotation on an interface (or an interface method), but this will only work as you would expect it to if you are using interface-based proxies. The fact that annotations are not inherited means that if you are
