[SOLVED] Spring WebService Multiple @PayloadRoot

Spring WebService Multiple @PayloadRoot

I'm setting up an @Endpoint to handle the following Soap message:

<Envelope xmlns:A="namespaceA" xmlns:B="namespaceB">
  <SOAP:Header/>
  <Body>
    <A:PayloadOne/>
    <B:PayloadTwo/>
  </Body>
</Envelope>

My method inside the @Endpoint class looks like the following. This works successfully but then I don't have the ability to access the PayloadTwo object.

@PayloadRoot(localPart = "PayloadOne", uri = "namespaceA")
void receive(@RequestPayload PayloadOne value) {...}

I'd like to setup my method so I can receive as method parameters, both payloads. For example:

@PayloadRoots({ 
  @PayloadRoot(localPart = "PayloadOne", uri = "namespaceA"), 
  @PayloadRoot(localPart = "PayloadTwo", uri = "namespaceB") 
})
void receive(@RequestPayload PayloadOne value1, @RequestPayload PayloadTwo value2) {...}

Is that possible?

Solution

Have not worked with Spring Boot @Endpoint in a while, but unless anything has changed recently, what you want is not possible. However, as a workaround, you can modify your SOAP message to add a wrapper:

<Envelope xmlns:A="namespaceA" xmlns:B="namespaceB">
  <SOAP:Header/>
  <Body>
    <A:PayloadWrapper>
      <A:PayloadOne/>
      <B:PayloadTwo/>
    </A:PayloadWrapper>
  </Body>
</Envelope>

Create a class that wraps PayloadOne and PayloadTwo:

public class PayloadWrapper {
  private PayloadOne payloadOne;
  private PayloadTwo payloadTwo;

  // Public getters/setters.
}

Then change your method:

@PayloadRoot(localPart = "PayloadWrapper", uri = "namespaceA")
public void receive(@RequestPayload PayloadWrapper payloadWrapper) {
  PayloadOne payloadOne = payloadWrapper.getPayloadOne();
  PayloadTwo payloadTwo = payloadWrapper.getPayloadTwo();
  ...
}
