How have you verified the contents of the response? It works for me using curl or HTTPie. If you'd like us to spend more time investigating, please provide a complete example of how to reproduce the problem (something that we can unzip or git clone and run) including how you are calling the service and checking the contents of the response.

@wilkinsona you can clone from https://github.com/damozhiying/spring-boot-demo
when app startup can look in http://127.0.0.1:8080/swagger-ui.html#/

Thanks. As suspected, this isn't due to Spring Boot. The response is as expected when accessed with curl:

$ curl localhost:8080/apis/gateway-conf/test2
{"bi":999999999999999889,"name":"abc"}

The problem only occurs when Swagger UI is involved. See swagger-api/swagger-ui#2030.
