我来自 Windows .NET 背景，但我正在努力扩展我的专业知识，因此选择了一些 Java 项目。目前，我正在尝试创建一个 REST API，所以我决定在这里完成泽西岛的演练：http: //jersey.java.net/nonav/documentation/latest/getting-started.html

我已经让 Hello World 项目在 Windows 中正常工作（使用 NetBeans 和 Maven），但是当我尝试在 Ubuntu 中做同样的事情（再次使用 NetBeans 和 Maven）时，我收到以下错误：

我看过这个帖子：Grizzly 和 Jersey 独立 jar，并修改了我的 pom.xml 以拥有他拥有的构建部分，但仍然遇到同样的错误。我的代码几乎是从示例中取出的，但我会在这里发布：

HelloWorldResource.java：

/*

 * and open the template in the editor.
 */
package com.javarest.javarest2;

import javax.ws.rs.*;

/**

// The Java class will be hosted at the URI path "/helloworld"
@Path("/helloworld")
public class HelloWorldResource {

    // The Java method will process HTTP GET requests
    @GET
    // The Java method will produce content identified by the MIME Media
    // type "text/plain"
    @Produces("text/plain")
    public String getClichedMessage() {
        // Return some cliched textual content
        return "Hello World";
    }
}

我没有使用 Maven。截至今天（2013 年 7 月 26 日），我包括以下 jar 以与我的 Eclipse 中的独立 grizzly 服务器一起使用（项目 | 运行 - 无 web.xml 等）

  • grizzly-framework-2.3.4.jar
  • grizzly-http-2.3.4.jar
  • grizzly-http-server-2.3.4.jar
  • jersey-container-grizzly2-http-2.0.jar

要下载文件：前往http://grizzly.java.net/dependencies.html并查找非 Maven 开发人员文件。控制台服务器看起来像

package test;

import java.io.IOException;
import java.net.URI;
import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory;
import org.glassfish.jersey.jackson.JacksonFeature;
import org.glassfish.jersey.server.ResourceConfig;
import org.glassfish.grizzly.http.server.HttpServer;


public class GrizzlyServer {

    private static final URI BASE_URI = URI.create("http://localhost:9090/service/");

    @SuppressWarnings("deprecation")
    public static void main(String[] args) throws IOException {


            final HttpServer server = GrizzlyHttpServerFactory.createHttpServer(BASE_URI, createApp());
            System.out.println(String.format("Application started.%nHit enter to stop it..."));
            System.in.read();
            server.stop();
    }

    public static ResourceConfig createApp() {
        ResourceConfig rc = new ResourceConfig()
        .packages("test")
        .register(JacksonFeature.class);

        return rc;

    }

}

好的，所以我现在拥有一台 Mac，并认为我会在那里尝试相同的程序。不出所料，我遇到了与在 linux 环境中相同的问题。我让一位同事在他的机器上尝试了相同的程序，但对他来说效果很好。当我这样做时，我唯一注意到不同的是我得到了以下弹出窗口： REST 弹出窗口

我一直只是点击确定。由于我的同事从未收到弹出窗口，我再次尝试，这次单击取消。这似乎成功了。

您需要使用 maven 转换器来确保正确合并服务文件。参见Grizzly 和 Jersey 独立罐
