前言

WebService 也叫XML Web
Service，WebService是一种可以接收从Internet或者Intranet上的其它系统中传递过来的请求，轻量级的独立的通讯技术。是通过SOAP在Web上提供的软件服务，使用WSDL文件进行说明，并通过UDDI进行注册。

一、使用HTTP+SOAP方式远程调用

maven引入依赖：

   <!--webservice 使用hutool的SoapClient -->

在线wsdl示例：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

package com.gcddd.earthquake.controller;

import cn.hutool.http.webservice.SoapClient;
import com.alibaba.fastjson.JSONObject;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

import java.io.StringReader;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
public class WebServiceTest {


        public static void main(String[] args) {
            //请求地址
            String soapUrl = "http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl";
            HashMap<String, Object> map = new HashMap<>();
            map.put("theCityName", "重庆");//请求参数，多个继续put即可
            SoapClient soapClient = SoapClient.create(soapUrl)
                    //请求方法,命名空间
                    .setMethod("web:getWeatherbyCityName", "http://WebXml.com.cn/")
                    .setParams(map);
            String sendSoap = soapClient.send(true);
            System.out.println(sendSoap);
            Map<String, String> map1 = new HashMap<String, String>();
            Map soapMap = XmlMap(sendSoap, map1);
            System.out.println(JSONObject.toJSONString(soapMap));


        }
    public static Map<String, String> XmlMap(String xml, Map<String, String> map) {
        try {
            SAXReader reader = new SAXReader();
            Document doc = reader.read(new StringReader(xml));
            Element root = doc.getRootElement();
            String path = "";
            if (map.containsKey(root.getName().trim())) {
                path = map.get(root.getName().trim());
                map.remove(root.getName().trim());
            }
            for (Iterator i = root.elementIterator(); i.hasNext(); ) {
                Element element = (Element) i.next();
                if (element.isTextOnly()) {
                    if (path.length() > 0) {
                        map.put(path + element.getName().trim(), element.getTextTrim());
                    } else {
                        map.put(element.getName().trim(), element.getTextTrim());
                    }
                } else {
                    map.put(element.getName().trim(), path + element.getName().trim() + ".");
                    XmlMap(element.asXML(), map);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return map;
    }

}

运行即可看到结果：

二、IDEA生成webservice客户端

1.idea添加webservice客户端模块

由于idea版本差异较大，功能所在不一样，我用的2023.1

设置-项目结构
在这里插入图片描述
模块-新增模块-webservice客户端

在这里插入图片描述

ws引擎选择Apaache Axis，选择之后可能不会出现代码生成的页面，可以先移除模块，然后右键项目
添加框架支持

其中生成的WebServiceTest代码貌似不能用，改为这样：

package example;

import mypackage.ICEApiService_PortType;
import mypackage.ICEApiService_ServiceLocator;
import mypackage.ResultModel;

import java.net.MalformedURLException;
import java.net.URL;
import java.rmi.RemoteException;

public class HelloWorldClient {
    public static void main(String[] argv) throws RemoteException, MalformedURLException {
        ICEApiService_ServiceLocator iceApiServiceServiceLocator = new ICEApiService_ServiceLocator();
        ICEApiService_PortType iceApiServiceImplPort = iceApiServiceServiceLocator.getICEApiServiceImplPort(new URL("http://IP:8808/ws/ice/api?wsdl"));
        ResultModel resultModel = iceApiServiceImplPort.send_open_message_data_new("eHFz", "测试消息推送", "这是摘要！", "这是消息推送正文！！！", "0dsa4906", "0", "https://www.baidu.com/", "1234", "0", "123");
    }
}
