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 --><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.7.22</version></dependency><dependency><groupId>org.dom4j</groupId><artifactId>dom4j</artifactId><version>2.1.3</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.7</version></dependency><dependency><groupId>javax.annotation</groupId><artifactId>javax.annotation-api</artifactId><version>1.2</version></dependency><dependency><groupId>org.dom4j</groupId><artifactId>dom4j</artifactId><version>2.1.3</version></dependency><dependency><groupId>org.apache.axis</groupId><artifactId>axis-jaxrpc</artifactId><version>1.4</version></dependency><dependency><groupId>org.apache.axis</groupId><artifactId>axis</artifactId><version>1.4</version></dependency><dependency><groupId>wsdl4j</groupId><artifactId>wsdl4j</artifactId></dependency><dependency><groupId>org.apache.cxf</groupId><artifactId>cxf-core</artifactId><version>3.4.3</version></dependency><dependency><groupId>org.apache.cxf</groupId><artifactId>cxf-rt-frontend-jaxws</artifactId><version>3.4.3</version></dependency><dependency><groupId>commons-discovery</groupId><artifactId>commons-discovery</artifactId><version>0.2</version></dependency>

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

模块-新增模块-webservice客户端

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");}
}

因为生成的lib包是外部的，需要加入进项目，或者安装到maven才能使用，右键”添加为库“

2.读入数据

总结

提示：这里对文章进行总结：
例如：以上就是今天要讲的内容，本文仅仅简单介绍了pandas的使用，而pandas提供了大量能使我们快速便捷地处理数据的函数和方法。
