在 WildFly 上部署 java 网络应用程序时出现错误 404
Error 404 while deploying a java web app on WildFly
我正在学习关于
https://www.youtube.com/watch?v=dmMdLW92hBA.
在项目中引入 index.xhtml 的最后一部分之前，一切都很顺利。
我在浏览器中收到 404 错误，在 wildfly 控制台日志中收到以下错误：

我创建了一个空 beans.xml 就像在教程中一样。

RestClient.java:

@ApplicationScoped

SimpleObject o = client.target("http://localhost:8080/RestExample/resources/MyRestService/object").request().get(SimpleObject.class);
System.out.println(o);
}
}

}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
我下载了代码库以及 WildFly 10.1.0.Final 服务器。我也遇到了同样的问题。
根本原因： 注释 @ApplicationPath 和 @Path 用于造成问题的相同 class。
@ApplicationPath 用于为整个应用程序提供基本 URI 路径。
@Path 用于自定义控制器 class 或 class 方法的单独 URI 路径。
这 RestService.java class 造成了问题。
修改RestService.java（从class中删除@ApplicationPath）：
@Path("/MyRestService")
public class RestService {
// http://localhost:8080/RestExample/resources/MyRestService/sayHello
@GET
@Path("/sayHello")
public String getHelloMsg() {
return "Hello World";
}
@GET
@Path("/echo")
public Response getEchoMsg(@QueryParam("message") String msg) {
return Response.ok("Your message was: " + msg).build();
}
@GET
@Path("/object")
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public SimpleObject getObject() {
return new SimpleObject(1, "Test");
}
}
我添加了一个新的 class RestApp.java。代码：
@ApplicationPath("/resources")
public class RestApp extends Application {
}
更新的项目结构：

@Path("/object")
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public SimpleObject getObject() {
return new SimpleObject(1, "Test");
}
}
我添加了一个新的 class RestApp.java。代码：
@ApplicationPath("/resources")
public class RestApp extends Application {
}
