一、WebService接口正常使用SOAP协议调用，测试时常采用SoapUI软件调用，具体如下：

二、由于目前主流web服务逐渐转换为RESTful的形式，且SOAP协议的实现也是基于HTTP协议，故存在通过HTTP调用WebService接口的可能

2.1 打开对应的WebService地址，目的地址location即为HTTP REST方式需要调用的服务地址

2.2 在HTTP REST 请求头中添加SOAPAction字段

SOAPAction 可以提供关于 SOAP 消息中要调用的具体操作或方法的信息。这对于接收方来说是非常重要的，因为它帮助确定如何解析和处理收到的 SOAP 消息

如果在发起 SOAP 请求时未在 SOAPAction 中提供有效的操作或方法信息，请求接收方可能会根据其他信息（例如消息体中的内容）来确定应该执行的操作，或者可能会采取默认行为来处理请求

此时SOAPAction可设置为空或者WSDL中对应的Operation（PACSreturn）

2.3 Body内容为xml格式，内容即为SoapUI调用时传输的全部内容

三、代码实现

import java.io.IOException;
import java.nio.charset.Charset;
import java.util.Objects;
import org.apache.http.HttpEntity;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.springframework.stereotype.Service;

@Service
public class PostSoap {

    // 请求超时时间
    static int socketTimeout = 10000;
    // 传输超时时间
    static int connectTimeout = 10000;

    public static String doPostSoap(String code, String message) {
        // 服务地址
        String webServiceURL = "http://10.146.8.226/csp/hsb/DHC.Published.PUB0007.BS.PUB0007.cls";
        // 拼接报文
        String soapXml =
            "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org\">\n"
                + "   <soapenv:Header/>\n"
                + "   <soapenv:Body>\n"
                + "      <tem:PACSreturn>\n"
                + "         <!--Optional:-->\n"
                + "         <tem:input1>" + code + "</tem:input1>\n"
                + "         <!--Optional:-->\n"
                + "         <tem:input2>" + message + "</tem:input2>\n"
                + "      </tem:PACSreturn>\n"
                + "   </soapenv:Body>\n"
                + "</soapenv:Envelope> ";
        // 创建HttpClient
        HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
        CloseableHttpClient closeableHttpClient = httpClientBuilder.build();
        // 创建Post请求
        HttpPost httpPost = new HttpPost(webServiceURL);
        // 设置请求和传输超时时间
        RequestConfig requestConfig = RequestConfig.custom()
            .setSocketTimeout(socketTimeout)
            .setConnectTimeout(connectTimeout).build();
        httpPost.setConfig(requestConfig);
        // 设置Post请求报文头部
        httpPost.setHeader("Content-Type", "application/xml");
        httpPost.setHeader("SOAPAction", "");
        // 添加报文内容
        StringEntity data = new StringEntity(soapXml, Charset.forName("UTF-8"));
        httpPost.setEntity(data);
        try {
            // 执行请求获取返回报文
            CloseableHttpResponse response = closeableHttpClient.execute(httpPost);
            HttpEntity httpEntity = response.getEntity();
            if (Objects.nonNull(httpEntity)) {
                // 打印响应内容
                System.out.println(EntityUtils.toString(httpEntity, "UTF-8"));
            }
            // 释放资源
            closeableHttpClient.close();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

    public static void main(String[] args) {
        String code = "接口001";
        String message = "报文xml";
        doPostSoap(code, message);
    }
}

运行结果
