这里我正在开发一个服务，它将接收SOAP请求消息，然后将其转换为JSON。之后，我想用转换后的JSON调用REST API，然后我想从该REST API接收JSON响应，最后我想将该JSON响应转换为SOAP响应消息，然后将其发送回调用方服务。因此，基本上这个服务将充当SOAP和REST通信之间的中间包装器服务。
我带着WSDL，需要通过使用Spring引导来实现这一点。请问有人能帮我吗?
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中生成了TestObj类，然后我试图将SOAP消息映射到TestObj类，但它抛出错误-
SOAP Body: [#document: null]

只要写和端点什么是你想要的
@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);
}
}
可以用WebClient代替RestTemplate。但基本上这就是你所需要的。对于SOAP部分，Spring Web Services将进行转换，对于JSON部分，Spring MVC将进行转换。你不需要自己去做。
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);
