java - Apache CXF - JAXRSServerFactoryBean 服务器已启动但无法访问端点

Question

我创建了 2 个类，一个是 RestService 类，另一个是主类。

import org.apache.cxf.endpoint.Server;
import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
import org.apache.cxf.jaxrs.lifecycle.SingletonResourceProvider;
import org.apache.cxf.transport.http.HttpDestinationFactory;
import org.apache.cxf.transport.servlet.ServletDestinationFactory;

public class RestDemo {

public static void main(String[] args) {

    final JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
    sf.setAddress("http://0.0.0.0:8080/");
    sf.setServiceClass(RestService.class);

    sf.setResourceProvider(RestService.class, new SingletonResourceProvider(new RestService()));

    ServletDestinationFactory destinationFactory = new ServletDestinationFactory();
    sf.getBus().setExtension(destinationFactory, HttpDestinationFactory.class);

    Server server = sf.create();
    server.start();
    System.out.println(server.isStarted());
      System.out.println(server.getDestination().getAddress().getAddress().getValue());
    System.out.println(server.getEndpoint().getEndpointInfo());

    try {
        Thread.sleep(1000000);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

}

sop 输出显示服务器已启动，但我无法在端点上执行任何 curd 操作。这是在linux下。我还尝试了linux命令“netstat -anp | grep 8080”来检查端口8080是否正在监听，但该命令的输出为空。任何帮助都将非常感激。

我需要它作为一个独立的程序，而不是将其作为与 spring 的 war 并将其部署在网络服务器中。我正在使用最新版本的 cxf，其中包含 jetty，因此启动函数预计将启动带有嵌入式 jetty 的服务器，但事实并非如此。

您的类路径中似乎没有所有必需的 jar。这是一个已部署资源的完整工作项目:

运行以下命令直接运行main

mvn package exec:java -Dexec.mainClass=com.example.CXFStandalone

主要:

package com.example;

import javax.ws.rs.GET;
import javax.ws.rs.Path;

import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
import org.apache.cxf.jaxrs.lifecycle.SingletonResourceProvider;


public class CXFStandalone {

    @Path("/")
    public static class RestService {

        @GET
        public String hello() {
            return "Hello world";
        }
    }

    public static void main(String[] args) {
        JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();
        sf.setResourceClasses(RestService.class);
        sf.setResourceProvider(RestService.class, new SingletonResourceProvider(new RestService()));
        sf.setAddress("http://localhost:9000/");
        sf.create();
    }
}
