Intellij 插件：无法初始化组件状态异常

Question

我正在尝试使用 Settings->Tools 中的一些配置创建一个 Intellij Idea 插件。

我有一个 ApplicationService 来保存和保存这些配置，但是调用 ServiceManager.getService(MyService.class) 时出现异常，并且在重新打开 Intellij Idea 时配置不会保留。

这是异常的堆栈跟踪：

com.intellij.diagnostic.PluginException: Cannot init  component state [Plugin: org.mycompany.mycompany-plugin]

除了它是一个 ApplicationService XML 参数之外，我没有找到关于“configurationSchemaKey”的文档 - 但我找不到我应该在其中输入什么值。一.

我是这样定义服务的：

<applicationService
                serviceImplementation="com.testmycode.config.SettingsService"
                id="com.testmycode.config.SettingsService"/>

我错过了什么？

Answer 1

configurationSchemaKey 属性是 ServiceDescriptor 的一部分，描述为：

Cannot be specified as part of {@link State} because to get annotation, class must be loaded, but it cannot be done for performance reasons.

但是，创建此类处理设置的服务并不常见。

请查看您当前的实施并遵循 IntelliJ Platform SDK DevGuide 中的 Introduction to Settings 指南。
