JHipster / Spring boot provides a nice endpoint /management/health, where it aggregates health information for subsystems like db, disk, and mail.
Unfortunately, when the connection to the mail server fails, the whole endpoint fails. So you do not get information what has failed.



I get a strack trace like this:



o.s.b.a.health.MailHealthIndicator : Health check failed

com.sun.mail.util.MailConnectException: Couldn't connect to host, port: XXXX, NNNN25025; timeout -1

at org.springframework.boot.actuate.endpoint.mvc.HealthMvcEndpoint.invoke(HealthMvcEndpoint.java:143)


This is spring boot 1.5.9
Where should I fix this, so that the exception is catched and instead a an error status is returned?

          I believe you can handle this error with the ExceptionHandler for 1.5.9 version of Spring Boot since the newer version there is no such problem:



           @ControllerAdvice
          public class ExceptionController

          @ExceptionHandler(MailConnectException.class)
          public ResponseEntity<?> mailExceptionHandler(MailConnectException e)
