How to Retrieve Custom Header Details from SOAP Requests in Spring Boot

When developing a SOAP request using Spring Boot, encountering issues in retrieving custom header details is not uncommon. Specifically, many developers struggle to extract the information packaged in soapenv:Header, leading to empty property values in their backend processing. If you've experienced this, don't worry! In this guide, we'll dive deep into the problem and provide a robust solution to effectively access those elusive header details.

The Problem

You may have structured your SOAP request correctly, but the retrieval of the custom headers still results in empty values. Here’s a quick overview of the SOAP request you might have crafted:

The question arises: What might be going wrong when trying to extract the RequestHeader data?

Breaking Down the Solution

The Right Approach

Initially, one might attempt to retrieve the header details with straightforward annotations, like so:

However, as you may have discovered, this method often leaves you with empty header values. The trick is instead to use the MessageContext object, which provides you direct access to the entire SOAP message, including headers.

Implementation Steps

Here's how you can effectively extract custom headers using the MessageContext:

Adjust Method Signature:
Replace your previous method signature to accept MessageContext as a parameter:

Conclusion

By adapting your approach to extract SOAP header information using the MessageContext, you can efficiently retrieve custom headers without encountering empty property values. This method provides you full flexibility to access and utilize the details encapsulated in the header.

If you're dealing with similar issues while crafting SOAP requests in Spring Boot, following the steps outlined in this blog could offer a significant breakthrough. Happy coding!
