Intellij插件：无法初始化组件状态异常

编程问答 2022-06-11

问题描述

我正在尝试使用Settings->Tools中的一些配置创建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)时会发生异常，并且该配置在重新打开Intellij Idea时不会持久。

这是异常的堆栈跟踪：

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

我没有找到有关“ configurationSchemaKey”的文档，除了它是applicationservice XML参数外，但我找不到应该输入的值。我

这是我定义服务的方式：

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

我想念什么？

解决方法

configurationSchemaKey属性是ServiceDescriptor的一部分，其描述为：

不能指定为{@link State}的一部分，因为要获取注释，必须加载类，但出于性能原因不能这样做。

但是，创建这种用于处理设置的服务并不常见。

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