jboss - 部署keycloak自定义spi部署

Question

我尝试创建一个自定义 spi，在我的 keycloak 项目中，遵循基本的 keycloack 结构，我添加了自定义提供程序接口(interface)，它扩展了提供程序、自定义提供程序工厂并为它们实现自定义 spi，如 keycloak 文档所述，它们在源代码中执行，之后，我为我的提供者和提供者工厂创建了一个自定义实现，我在 META-INF/services 中创建了文件，如文档所述，并且我使用 ear aproach 进行部署，就像在 beercloak 示例中一样，但是当我尝试使用我的提供者时抛出代码空指针异常，这仅在我尝试添加自定义 spi 时发生，如果我正在实现具有现有 keycloak spi 的提供程序，它也可以工作，如果我使用模块方法，它也可以工作，我在其中创建一个新模块使用 jboss-cli，但这种方法似乎很难维护，任何人都知道为什么会发生这种情况以及我该如何解决它或者最好的方法是什么，谢谢。

Answer 1

如果您仔细查看 $JBOSS_HOME/standalone/configuration/standalon-ha.xml或 $JBOSS_HOME/standalone/configuration/standalon.xml文件，你会在某处注意到这些行:

<providers>
    <provider>classpath:${jboss.home.dir}/providers/*</provider>
</providers>

这意味着，您需要将编译后的文件放在根目录下的文件夹中，${jboss.home.dir}/providers/在他们的 SPI 之前可以注册。

这样做基本上与在此处添加带有模块路径的新行相同，例如

<providers>
    <provider>classpath:${jboss.home.dir}/providers/*</provider>
    <provider>module:com/selast/keycloak-provider/*</provider>
</providers>

希望它对某人有所帮助，因为我已经花了一天的时间😃。
