英文:
I started an application with only these two classes as a sanity test, but I only get 404s. I run a get request from Postman at localhost:8080/TestApi-1.0-SNAPSHOT/test, which should hypothetically return "Hello World" but I get a 404 response. I'm using JBoss/Wildfly 14.0.0-Final as the server for reference. Any help would be appreciated. I'll include the two classes, the console output when deploying the server from IntelliJ, and the POM.

以下是翻译后的内容:
将TestResource.java 更改如下有所帮助。看起来由于某种原因,一个带有 @Path
注解的类未被识别为资源。
<-- 开始代码片段 -->
<-- 语言: lang-js -->
<------------------- 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();
}
}
<-- 结束代码片段 -->
英文:
Changing TestResource.java to look like below helped. Looks like for some reason a class isn't recognized as a resource with the @Path
annotation.
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
<------------------- 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();
}
}
