我想使用 Jakarta 和 TomEE Plume 服务器创建我的第一个 REST Api。
通过 HTTP 进行部署和 api 调用是有效的，但我仍然需要修复异常，因为要学习如何正确编程。
在服务器启动时，我收到此错误消息：

但前提是包含我的第一个测试 REST Api 文件：
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;
@Path("/hello")
public class HelloResources {
@GET
@Path("/test")
@Produces(MediaType.TEXT_PLAIN)
public String sayHello() {
return "Hello World";
}
}
如果需要，我可以为您提供更多详细信息。
我也面临着同样的问题。
我不知道为什么，但即使不需要 beans.xml（CDI 部署描述符），似乎将其放入 Web 应用程序存档中就可以解决问题。
它应该位于 WEB-INF 目录中：
对于 Web 应用程序，beans.xml 部署描述符（如果存在）必须位于 WEB-INF 目录中。对于 EJB 模块或 JAR 文件，beans.xml 部署描述符（如果存在）必须位于 META-INF 目录中。
按照惯例，META-INF 和 WEB-INF 文件夹位于 webapp 目录下（Web 应用程序入门 > Web 应用程序存档 > 构建示例项目）。
