Question

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

我有一个控制器名称ContributionPlanController。它有一个服务ContributionPlanservice。

在ContributionPlanService中，它有ProductService和一些其他服务，包括JointPIAService。

JointPIAService it self，继承自ProductService

我在ProductService上做了一些修改，就像println上的东西一样，这个错误总是出现。如果我重新启动应用程序，它将正常工作。

知道如何解决这个问题吗？

Answer 1

当您在ContributionPlanController中声明ContributionPlanService时，您是通过显式输入（“ContributionPlanService contributionPlanService”）还是使用动态类型（“def contributionPlanService”）来实现的？

在1.0.4中，自动布线和热交换的组合仅适用于动态类型（def ...）。也就是说，显式声明的服务在第一次启动应用程序时会自动连接，但此后热插拔会被挫败。将声明更改为def将使热交换工作，但是您失去了IDE帮助您的好处。

现在您提到它，我希望这将在1.1.x中修复，但我还没有尝试过。（我现在无法正确测试它，但我不想等你发送这个答案。试试看，让我知道。）
