Resteasy 應用程序總是返回 404

Question

我啟動了一個只有這兩個類的應用程序作為健全性測試，但我只得到 404。 我在 localhost:8080/TestApi-1.0-SNAPSHOT/test 運行來自 Postman 的 get 請求，假設它應該返回“Hello World”，但我收到了 404 響應。 我使用 JBoss/Wildfly 14.0.0-Final 作為服務器以供參考。 任何幫助，將不勝感激。 我將包括這兩個類、從 IntelliJ 部署服務器時的控制台輸出和 POM。

Answer 1

將 TestResource.java 更改為如下所示有幫助。 看起來由於某種原因，一個類沒有被識別為帶有@Path注釋的資源。

 <------------------- 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(); } }
