调用webservice接口有好多种方式，比如wsimport生成呀，CXF，JAX-WS，尝试过以后都是各种步骤，各种注意，特别加上鉴权方式不同，搞的复杂N倍，还难排查问题，如果你用到其中某种方式也遇到了其中的问题，那我们来用最原始的HttpURLConnection方式吧，包你满意，哪里有问题一眼就看到了。废话不多说，开始！

一、准备好SOAP请求体，你测试肯定会有SOAPUI这个工具吧，只要你导入wsdl，上面就有哦

二、代码

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;public class BasicAuthSoapClient {public static void main(String[] args) throws Exception {String username = "yourname";String password = "yourpwd";String wsdlUrl = "xxxxxx?wsdl";// 编码用户名和密码String auth = Base64.getEncoder().encodeToString((username + ":" + password).getBytes());// 创建URL对象URL url = new URL(wsdlUrl);HttpURLConnection conn = (HttpURLConnection) url.openConnection();// 设置请求方法conn.setRequestMethod("POST");conn.setDoOutput(true);// 设置基本身份验证头conn.setRequestProperty("Authorization", "Basic " + auth);// 设置其他必要的请求头，如Content-Type等conn.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");conn.setRequestProperty("SOAPAction", ""); ##这是啥呢，这就是你wsdl的namespaceURI和localPart组合哦。就是QName的两个参数啦，举个例子http://xxx.ws.itl.com/，xxxServiceconn.setDoOutput(true); ## 你的请求体啦～～～String soapRequest="";try (OutputStream os = conn.getOutputStream()) {byte[] input = soapRequest.getBytes("utf-8");os.write(input, 0, input.length);}// 发送请求并获取响应int responseCode = conn.getResponseCode();System.out.println("Response Code : " + responseCode);BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));StringBuffer response = new StringBuffer();String inputLine;while ((inputLine = in.readLine()) != null) {response.append(inputLine);}in.close();// 打印响应内容System.out.println(response);}
}

三、请求一下哦，简单又明了。也不难排查。简直完美～～
