Grails 3.3 - 如何替换已弃用的服务工件?
Grails 3.3 - How to replace deprecated Service artefact?
我即将把我的 Grails 3.2 网络应用程序升级到 3.3 版。
特别是,我创建了一个 BaseService
抽象 class(位于 /src/groovy
)提供了几个辅助方法,我的大部分 Grails 服务都扩展了 BaseService
。
import grails.artefact.Service
abstract class BaseService implements Service {
...
}
我注意到 Grails 3.3 grails.artefact.Service
及其超级 class grails.events.Events
.
已被弃用
我可以用什么代替 Service
来避免保留对已弃用 class 的引用?
弃用是因为 New Events API and Async Framework。如果你阅读了 grails 3 的文档,你会发现:
In order to support multiple different asynchronous and reactive
frameworks Grails 3.3 has been decoupled from Reactor 2.x and an
abstract EventBus notation added.
The EventBus interface provides the foundation and multiple
implementations including GPars and RxJava.
A new set of annotations usable in services classes and regular Spring
beans can be leveraged to publish and consume events:
Publisher - A transformation that transforms a method ensuring the
return value is published as an event
Subscriber - A transformation that transforms a method to listen for
an event.
因此,如果您的 implements Service
用于使用 Events
,那么您已经
使用 grails 3 async
和 events
更新您的事件实现
插入。查看异步框架文档#events 部分。
