在WildFly上部署Java Web应用程序时的404

问题描述 投票：1回答：1

我一直在遵循以下教程https://www.youtube.com/watch?v=dmMdLW92hBA，直到一切顺利，直到引入index.xhtml的最后一部分为止。我在浏览器和控制台中收到404错误，得到以下错误：

就像在本教程中一样，我创建了一个空的beans.xml。

我的index.xhtml的内容：

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
          "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">
<h:head>
</h:head>
<h:body>
    <h:form>
        <h:commandButton value="Call Webservice" action="#{restClient.call()}" />
    </h:form>
</h:body>
</html>

RestClient.java：

import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

@ApplicationScoped
@ManagedBean
public class RestClient {

    public void call() {
        Client client = ClientBuilder.newClient();

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

        System.out.println(o);
    }
}

RestService.java：

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("/MyRestService")
@ApplicationPath("/resources")
public class RestService extends Application {
    //  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");
    }
}

SimpleObject.java：

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class SimpleObject {

    private int id;
    private String name;

    public SimpleObject() {

    }

    public SimpleObject(int id, String name) {
        super();
        this.id = id;
        this.name = name;
    }
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }


}

用@ApplicationScoped替换@RequestScoped。

将代码更新为此：

@RequestScoped
@ManagedBean
public class RestClient {

    public void call() {
        Client client = ClientBuilder.newClient();

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

        System.out.println(o);
    }
}
