java - 奇怪的grails错误消息

使用grails 1.1.1
在对服务进行修改，然后尝试刷新页面时，收到了此消息。

我有一个 Controller 名称ContributionPlanController。
它具有服务ContributionPlanservice。

在ContributionPlanService内部，它具有ProductService和其他一些服务，包括JointPIAService。

自己的JointPIAService，继承自ProductService

我对ProductService进行了修改，例如对某些内容进行了println，并且始终出现此错误。如果我重新启动该应用程序，它将可以正常工作。

知道如何解决这个问题吗？

最佳答案

在ContributionPlanController中声明ContributionPlanService时，是使用显式类型(“ContributionPlanServicetributionPlanService”)还是动态类型(“deftributionPlanService”)进行了声明？

在1.0.4中， Autowiring 和热插拔的组合仅适用于动态类型(def ...)。也就是说，一个明确声明的服务将在您第一次启动该应用程序时自动连接好，但是此后的热交换将被阻止。将声明更改为def会使热插拔工作正常进行，但随后您将失去IDE帮助您的好处。

既然您提到了它，我希望可以在1.1.x中修复它，但是我还没有尝试过。 (我目前无法立即对其进行测试，但我不想等待向您发送此答案。请尝试并让我知道。)
