java - Resteasy 应用程序总是返回 404
问题描述
我开始了一个只有这两个类的应用程序作为健全性测试,但我只得到 404。我在 localhost:8080/TestApi-1.0-SNAPSHOT/test 上运行来自 Postman 的 get 请求,假设它应该返回“Hello World”,但我得到了 404 响应。我使用 JBoss/Wildfly 14.0.0-Final 作为服务器供参考。任何帮助,将不胜感激。我将包括两个类,从 IntelliJ 部署服务器时的控制台输出和 POM。

return Response.ok("Hello World").build();
}

解决方案
将 TestResource.java 更改为如下所示有所帮助。看起来由于某种原因,一个类没有被识别为带有@Path
注释的资源。
<------------------- TestResource.java ------------------------>
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
@Path("/")
public class HelloResource {
@Path("/test")
@GET
public Response hello(){
System.out.println("Running test service here");
return Response.ok("Hello World").build();
}
}
