This open source library is capable of converting SOAP backend service to REST backends. The library is written to get the SOAP Webservice contract using WSDL file and generate OpenAPI Specification (Swagger file) along with the required SOAP Request bodies that will convert the REST JSON input to SOAP message. There are two methods to convert the SOAP Endpoints. Either using the URL of the real SOAP backend or the Zip file contain all the WSDL files and respective XSD files.

Clone the repository and build the project using executing following command in terminal

mvn clean install

Prerequisites

• Maven 3.6.3 or higher (tested on 3.6.3)
• Java 11.0 or higher (tested on java 11)

There are two methods in SOAPToRestConverter.java that convert the WSDL to REST Endpoint

1. Use the following method to generate REST service from WSDL URL

getSOAPtoRESTConversionData(URL url,String apiTitle,String apiVersion)

2. Use the following method to generate REST service from WSDL File

getSOAPtoRESTConversionData(String filePath,String apiTitle,String apiVersion)

Both methods will return an object from SOAPtoRESTConversionData.java class which contains following

OpenAPI openAPI;
        Map<String, SOAPRequestElement> soapRequestBodyMapping;
        String soapService;
        String soapPort;

• openAPI, soapService and soapPort are the respective representation of the SOAP endpoint
• soapRequestBodyMapping contains a map of SOAPRequestElement for all the SOAP operations.

SOAPRequestElement Contains following,

Document soapRequestBody;
        String soapAction;
        String soapNamespace;
        String nameSpace;

Document contains org.w3c.dom.Document of the Request message that need to send to the SOAP backend under soapAction. This Document contains the message with the placeholders for JSON input

Build the JAR with command mvn package. Then you can generate a YAML output for any WSDL file like this:

java -jar target/soaptorest-1.6-jar-with-dependencies.jar src/test/resources/complex/nested.wsdl MyNestedRestAPI 1.6.2

After the jar file in the command, the 1st parameter (required) is the path to the WSDL file. The 2nd parameter is the REST API title (default WSDL file name), and the 3rd is the version number (default "1.0.0").
