How to Generate a Single WSDL for Multiple SOAP Endpoints in Spring

Spring is a powerful framework, especially when it comes to developing SOAP web services. However, developers might hit a snag when trying to generate a WSDL file for multiple services. If you've ever faced the issue of Spring generating a WSDL only for the first endpoint configured, you’re not alone.

In this guide, we will explore this challenge and explain how Spring can be configured to generate a single WSDL encompassing multiple SOAP endpoints.

The Problem

You may have a scenario where your application contains multiple SOAP endpoints, each with its own XSD schema file. When configured correctly, we expect Spring to generate a unified WSDL that describes all these endpoints. Instead, you might find that Spring only generates the WSDL for the first endpoint mentioned in your configuration class. This leads to confusion and the difficulty of managing separate WSDL documents for each service.

The Solution

The good news is that it is indeed possible to generate a single WSDL for all your endpoints in Spring, but it requires proper configuration. The key lies in structuring your schemas correctly.

Key Configuration Steps

Combine XSD Files:
The first step is to create a single XSD file that encompasses all the requests and responses of your SOAP services. Here’s a simple XML structure you can follow:

Update Configuration Class:
In your Spring configuration class, ensure that this combined XSD file is referenced. The configuration will typically look like this:

Conclusion

By combining all your request and response schemas into a single XSD file and configuring your Spring application correctly, you can easily generate a single WSDL that accurately describes all your SOAP endpoints. Not only does this simplify your development process, but it also provides clarity and coherence in your service documentation.

If you are working with multiple SOAP services in your Spring application, this approach can save a significant amount of effort and confusion down the line. Don’t hesitate to implement this effective solution and streamline your service management!

Now, go ahead and give it a try. You’ll find that managing your SOAP services becomes much more manageable with a single WSDL file at your disposal.
