一、调用jdk自带的Endpoint类，通过端点发布

1、新建项目

a.File -> New Project…菜单打开新建项目窗口，依次选择Java，WebServices，Version项选择Apache Axis，Libraries项选择 Download。然后点击Next按钮进入下一页
输入项目名称，然后点击Finish按钮开始下载依赖包。（下载依赖包可能会失败，建议多次尝试）依赖包下载完成后进入新建的项目

2.开发服务器端

在项目下新建一个包webservice_student_server
在包中新建一个接口StudentInterface，在接口中声明一个查询的方法studentQuery(int number)

package com.webservice.server;

public interface StudentInterface {
    public abstract String studentQuery(int number);
}

新建StudentInterface接口的实现类StudentInterfaceImp，在类中实现StudentInterface接口中的查询方法studentQuery(int number),调用jdk自带的Endpoint类，通过端点发布

package com.webservice.server;

import javax.jws.WebService;
import javax.xml.ws.Endpoint;

@WebService
public class StudentInterfaceImp implements StudentInterface {
    String name[]={
            " 姜倩云 "," 张丽梅 "," 吴美庆 "," 张忠敏 "," 王雅蓉 "," 葛红敏 "," 赵斌灿 "," 王严鑫 ",
            " 莫可宏 "," 王猛 ", " 侯勇军 "," 马铸辉 "," 易鹏 "," 罗路辉 "," 闫治鹏 "," 孙磊 "," 李佳玲 ",
            " 王勃博 "," 康尧 "," 张波 ", " 邓雷 "," 陈佳鑫 "," 唐炜宁 "," 葛龙 "," 倪赛杰 "," 陈成 ",
            " 刘浩浩 "," 周子轩 "," 宫蕊 "," 文云丽 "," 沈雪 "," 刘冬媛 "," 褚蓉 "," 钱苑 "," 董樟裕 ",
            " 马凌杰 "," 王京源 "," 陈辉云 "," 罗建兴 "," 陈晨 "," 赵文宇 "," 宗玮雯 "," 赵贝贝 ",
            " 黄豪琛 "," 娄宽 "," 任上海 "," 王康 "," 沈楠 "," 蒋宇 "," 吕阳 "," 王刚 "," 王扬 "," 吕中剑 ",
            " 张军 "," 卢惺鑫 "," 姚礼宗 "
    };
    @Override
    public String studentQuery(int number) {
        System.out.println("from client..." +" 学号 :" +number);
        String result = name[number];
        System.out.println("to client..." + " 姓名 :"+result);
        return result;
    }
   public static void main(String[] args) {
        //java jdk提供一个自带的类可以将java应用程序发布成webservice
        /**
         * Endpoint.publish(String address, Object implementor):
         * 参数1：提供服务对外的访问地址
         * 参数2：提供服务的类的对象
         *
         * */
        Endpoint.publish("http://localhost:8080/StudentInterfaceImp", new StudentInterfaceImp());
        System.out.println(" 发布成功 ...");
    }
}

运行该程序，看到以下提示信息，说明该服务已经启动
在浏览器地址栏中输入http://localhost:8080/StudentInterfaceImp?wsdl 回车，看到以下界面，说明服务发布成功

3、开发客户端

新建Java Project,项目名称为：webserviceDemo_client,在该项下新建包com.webservice.client
找到该项目的src的绝对目录
打开CMD窗口，执行生成命令 wsimport -s “src目录” -p “生成类所在包名” -keep wsdl发布地址，如下图
新建Client窗体类，调用服务

package com.webservice.client;

import com.webservice.service.StudentInterfaceImp;
import com.webservice.service.StudentInterfaceImpService;

import javax.swing.*;
import javax.swing.border.EmptyBorder;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Client extends JFrame {
    private JPanel contentPane;
    private JTextField textField;
    private JButton search;
    private JButton cancel;
    private JTextArea textArea;
    private StudentInterfaceImpService impService;
    private StudentInterfaceImp imp;
    String result;
    private static int number=0;
    public Client(String string) {
       setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 450, 300);
        contentPane = new JPanel();
        contentPane.setForeground(Color.WHITE);
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(null);
//       System.out.println("请输入学号进行查询");
       JLabel label = new JLabel(" 请输入学号进行查询 ");
        label.setForeground(Color.BLUE);
        label.setBounds(155, 10, 129, 50);
        contentPane.add(label);
        textField = new JTextField("20");
        textField.setBounds(155, 58, 110, 22);
        contentPane.add(textField);
        textField.setColumns(10);
        //  通过 webservice 的服务视图
        impService = new StudentInterfaceImpService();
//  获得服务端点
        imp = impService.getStudentInterfaceImpPort();
        search = new JButton(" 查询 ");
        search.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                if (e.getSource() == search) {
                    number = Integer.parseInt(textField.getText().toString());
                    if (number > 56 || number < 1) {
                        result = " 非法输入！ ";
                        textArea.setText(result);
                    } else {

                        textArea.setText(" 你输入的学号是： " + number + "\n" + " 查询结果为：  " +  imp.studentQuery(number));
                        System.out.println( imp.studentQuery(number));
                    }
                }
            }
            });
       search.setBounds(139, 104, 73, 23);
       contentPane.add(search);
       cancel = new JButton(" 取消 ");
       cancel.addActionListener(new ActionListener() {
                    public void actionPerformed(ActionEvent arg0) {
                        textField.setText("");
                        textArea.setText("");
                    }
                });
   cancel.setBounds(222, 104, 73, 23);
   contentPane.add(cancel);
            textArea = new JTextArea();
   textArea.setBounds(105, 153, 223, 70);
   contentPane.add(textArea);
            Component glue = Box.createGlue();
   glue.setBounds(61, 196, 1, 1);
   contentPane.add(glue);
        }
        public static void main(String[] args) {
            Client frame = new Client(" 自定义 web service 调用 ");
            frame.setVisible(true);
        }
    }

运行结果

二、IDEA直接生成wsdl文件，并通过服务器发布

1、在服务端新建包calculate_server，并新建类Circle

package calculate_server;

import javax.jws.WebService;

@WebService
public class Circle {
    public double area(double radius){
        return Math.PI * radius * radius;
    }
}

2、服务器配置

打开Edit Configurations…菜单
在Run/Debug Configurations窗口里点击+按钮，在出现的菜单里选择Tomcat Server --> Local
然后在添加的Tomcat Server配置页面中配置服务器的Name、Application server和HTTP Port，配置页面底部可能会显示有Warning，点击警告信息右侧的Fix…按钮切换到Deployment标签页。
添加 Artifact 后的界面如下，已经没有警告了，点击OK
选择File–> Project Structure…菜单
在出现的窗口中选择Project Settings --> Artifacts，会到在新的警告信息。点击警告信息右侧的Fix…按钮,选择Add ‘JAX-WS-Apache Axis’ to the artifact,然后点击OK
