HTTP REST 方式调用WebService接口（wsdl）

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：https://img-blog.csdnimg.cn/direct/21d8ec49e2f5458c91348ac422ab3ca0.png" />

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https://img-blog.csdnimg.cn/direct/31ee79f455c649daac4e6aa5ff983a15.png" />

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

@Service

        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);

            }
            // 释放资源
            closeableHttpClient.close();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
