jihor/spring-boot-kotlin-service-example

An example of Spring Boot service written in Kotlin

Uses Spring Boot 5, Java 11, Kotlin 1.3

Done:

• Gradle build
• Model
• REST API
• SOAP API
• Stub implementation
• OpenAPI Spec + Swagger UI
• "External" SOAP service invocation using CXF
• MapStruct
• "External" REST service invocation using WebClient
• SpEL Gates
• Async SOAP invocation
• Merge 2 async responses using Reactor
• Minimal logging w/Log4j2
• Generate classes using OpenAPI spec

To do:

• Generate Spring Boot RestController, see https://github.com/OpenAPITools/openapi-generator/wiki/Server-stub-generator-HOWTO#java-springboot (probably will generate a lot of classes, should try to exclude everything but the RestController)
• Error handling in async actions
• Hystrix Resilience4j
• Base UI
• Tests
• Docker-compose to run the whole thing

Try:

• "External" SOAP service invocation using Web Client's Soap Async API (what's it called?) instead of generated WSDL methods
• Coroutines instead of reactive pipes (https://stackoverflow.com/questions/55684117/how-to-return-a-kotlin-coroutines-flow-in-spring-reactive-webclient)

How to start

1. Run mock
2. Run service with -Dservice.timeout=1000 -Dservice.systemAEndpoint=http://localhost:8090/soap-api/system-a -Dservice.systemBUrl=http://localhost:8090
