我正在尝试 4.0.0-M1 和 helidon-mp。我有一个简单的应用程序，带有数据库连接。但是我正在使用 CDI，并且想知道为什么没有暴露端点。我在 localhost:8080 上的所有端点都会产生 404 （例如 /health、/metrics、/rateMgmt/v1 - 我的端点）。我想知道是否有一种特殊的方法来列出所有可用的端点，或者 CDI 是否在 4.0.0-M1 中尚不可用。
这是我的启动日志：

我想知道 CDI 没有出现在列出的功能中。
....
我可以自己回答。我创建了一个 uber-jar，显然 CDI 检测不起作用。 使用 slim jar，我在启动时得到这些日志：

正如您自己发现的那样，Helidon 不支持 uber-jars。
