Grails服务中的服务声明错误 [英] Error in Declaration of service within Grails service

问题描述

我对在其他服务中使用服务感到担忧.有些工作，但是其他却没有.问题是我不知道怎么了.

I have concerns about the use of Services within other Services. Some work, but others don't. The problem is that I can't figure out what's wrong.

当您添加生成错误的服务时，总是会出现相同的问题，因此我撤消了对有问题的服务的引用，系统恢复了正常.

When you add a service that generates the error always occurs the same problem, then I withdraw the reference to service problematic and the system returns to normal.

我想知道这是否会影响任何循环引用，从而造成不稳定.

I wonder if the same is effecting any circular reference creating instability.

class UserService {
    def terceirizadoService
    def unidadeService
    def grailsApplication
    def springSecurityService
    def tabService   //If I remove this line the system works
    ...
}


class TabService {
    def contratoService, grailsApplication ...
}

当对具有对tabService服务的引用的域进行Bootstrap引用时，会发生错误.

The error happens when the Bootstrap reference is made to a domain that has a reference to the tabService service.

class Car implements Serializable {
    transient tabService
    ...
}

我正在使用Grails 2.3.7

推荐答案

每当我们使用prototype作用域服务时(我们不确定是否适用于您)，我们也遇到过类似的问题.

We've seen issues like this whenever we use prototype scoped services as well (not sure if that applies to you).

作为解决方法，您可以通过不注入tabService而是按需获取它来解决该问题:

As a work around you could solve it by not injecting the tabService but getting it on demand:

def getTabService() {
    grailsApplication.mainContext.getBean(TabService)
}

显然不理想.
