为了学习如何做，我正在尝试设置我的第一个示例 Web 项目。我在一个名为“com.java24hours.ws”的包中有 4 个类。我正在尝试将 Eclipse 中的 SquareRootClient 类作为 java 应用程序运行。我收到一个 java.net.ConnectException（我在上课后发布了错误日志）。谁能告诉我我做错了什么？

SquareRootClient

package com.java24hours.ws;

import java.net.*;
import javax.xml.namespace.*;
import javax.xml.ws.*;

class SquareRootClient {
    public static void main(String[] arguments) throws Exception {
        URL url = new URL("http://127.0.0.1:5335/service?wsdl");
        QName qname = new QName(
            "http://ws.java24hours.com/",
            "SquareRoorServerImplService"
        );
        Service service = Service.create(url, qname);
        SquareRootServer srs = service.getPort(SquareRootServer.class);

        System.out.println(srs.getTime());
        System.out.println(srs.getSquareRoot(625D));
    }
}

平方根服务器

package com.java24hours.ws;

import javax.jws.*;
import javax.jws.soap.*;
import javax.jws.soap.SOAPBinding.*;

@WebService

@SOAPBinding(style = Style.RPC)

public interface SquareRootServer {
    // get the square root of a number
    @WebMethod double getSquareRoot(double input);

    // get the current time and date as a string
    @WebMethod String getTime();

}

SquareRootServerImpl

package com.java24hours.ws;

import java.util.*;
import javax.jws.*;

@WebService(endpointInterface = "com.java24hours.ws.SquareRootServer")

public class SquareRootServerImpl implements SquareRootServer {

    public double getSquareRoot(double input) {
        return Math.sqrt(input);
    }

    public String getTime() {
        Date now = new Date();
        return now.toString();
    }
}

SquareRootServerPublisher

package com.java24hours.ws;

import javax.xml.ws.*;


public class SquareRootServerPublisher {

    public static void main (String [] arguments ){
        SquareRootServerImpl srsi = new SquareRootServerImpl();
        Endpoint.publish("http://127.0.0.1:5335/service", srsi);
    }
}
