I have trouble in applying Java Spring boots with some rules: - If parameters values do not match the specifics possible values you should return HTTP status code 400("Bad Request") - Responses should have Content-Type header with approriate value(application/json) - If you need to create multiple classes - You can use only the following libraries:
Spring web MVC (v.5.0.7.Release)
Faster XML Jackson, Jackson datatype JSR310
I need detailed method read healtcheck with message: {"currentTime" : "2020-06-01T20:45:35Z,"application":"OK"}
You can customise the health check endpoint by implementing HealthIndicator and providing custom logic.
For example, you can check out simple implementation here (https://www.amitph.com/custom-health-check-spring-boot-actuator/).
