如何在spring boot java接收到SOAP Message并转换为JSON？

Question

在这里，我正在开发一个服务，它将接收一个 SOAP 请求消息，然后将其转换为 JSON。之后，我想调用一个 REST API 和转换后的 JSON 然后我想从那个 881569900718588 接收响应 81341428131688 API API 最后我想将 JSON 响应转换为 SOAP 响应消息，然后将其发送回调用方服务。 所以基本上这个服务将充当 SOAP 和 REST 通信之间的中间 Wrapper 服务。

我有 WSDL，需要一种方法来使用 Spring 启动。 有什么可以帮助我吗？

目前我正在做如下 -

@RestController
public class WrapperController {

  @PostMapping(
      value = "/wrap",
      consumes = MediaType.APPLICATION_XML_VALUE,
      produces = MediaType.APPLICATION_JSON_VALUE)
  public Q248Req wrapSOAPRequest(@RequestBody String SOAPReq)
      throws SOAPException, IOException, JAXBException {
    System.out.println("SOAP Request: " + SOAPReq);
    SOAPMessage message =
        MessageFactory.newInstance()
            .createMessage(null, new ByteArrayInputStream(SOAPReq.getBytes()));
    Unmarshaller unmarshaller = JAXBContext.newInstance(TestObj.class).createUnmarshaller();
    TestObj Req =
        (TestObj) unmarshaller.unmarshal(message.getSOAPBody().extractContentAsDocument());

    return Req;
  }

我已经从提供的 WSDL 生成了 TestObj class 然后我试图将 map SOAP 消息发送给 TestObj class 但它抛出错误 -

SOAP Body: [#document: null]

Answer 1

只需编写并终结您想要的内容即可。

@Endpoint
public class YourEndpoint {

  public final RestTemplate rest;

  public YourEndpoint(RestTemplate rest) {
    this.rest=rest;
  }


  @PayloadRoot(localName="YourRequestFromWsdlRequest")
  @ResponsePayload
  public YourResponseFromWsdl method(@RequestPayload YourRequestFromWsdl) {
    return rest.postForObject(rest-url, YourRequestFromWsdl, YourResponseFromWsdl.class);
}
}

您可以使用WebClient而不是RestTemplate 。 但基本上这就是你所需要的。 对于 SOAP 部分 Spring Web 服务将进行转换，对于 JSON 部分 Spring MVC 将进行转换。 你不需要自己动手。

Answer 2

Please try using  (com.ibm.json.xml.XMLToJSONTransformer) Library which help you to convert Soap String(i.e Request Body) to Json Object



String jsonObjectStr ="";

// convert String to JSONObject
jsonObjectStr = xmlToJsonTransformer.transform(SOAPReq);
  JSONObject.parse(jsonObjectStr);
