Building SOAP Wer Service Client using Spring Boot - web-services

Question

I am new to Spring Boot and not familiar with how SOAP web service work.
I am trying to consume a SOAP web service using Spring Boot. I am following the reference given at the official website : https://spring.io/guides/gs/consuming-web-service/
My code is exactly the same as given in the reference. When I try to run the code using mvn clean install, it throws following compilation error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project springboot-demo: Compilation fail
ure: Compilation failure:

The code which I am running is at: https://github.com/spring-guides/gs-consuming-web-service/tree/master/complete.

Answer 1

The contract driven SOAP web-service development is you need to get the WSDL file and generate the Java domain classes and stub (via jaxb utilities), and you can then develop client to talk to the server.
And the error message you pasted means your client stub classes did not get generated successfully. I could not find any WSDL file copy locally in that github repo, and the access to the WSDL file seems go 404 error as well .
So you probably need to try some other tutorials like CXF ones. It is very straightforward as well.
