Question

我担心在其他服务中使用服务。有些工作，但其他人没有。问题是我无法弄清楚错误。

当你添加一个生成错误的服务总是出现同样的问题时，我撤回对服务有问题的引用，系统恢复正常。

我想知道是否会影响任何创建不稳定性的循环引用。

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 ...
}

对具有tabService服务引用的域进行Bootstrap引用时会发生错误。

class Car implements Serializable {
    transient tabService
    ...
}

并生成此日志：

我使用的是Grails 2.3.7

每当我们使用prototype作用域服务时，我们都会遇到类似的问题（不确定这是否适用于您）。

作为一种解决方法，您可以通过不注入tabService但按需获取它来解决它：

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

显然不太理想。

Grails服务中的服务声明出错
