I have used 

server.connection-timeout=-1

in application.properties but it still disconnects after some time.

I even used 

spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1

in application.properties but to no avail. What I'm I doing wrong?

  • This seems to be Gradle related. Do you experience the same symptoms if you run your app's JAR file? with `java -jar ...`? – Strelok Feb 13 '17 at 12:20
  • i have not tried that,but I highly doubt that's the issue.I'll give it a try and see. – Rbk Feb 13 '17 at 14:45
  • Do you have any proof that this is a DB connection related issue ? if not, try checking the code for file reading, and catch the java.io.IOException on file reading part. it may help. – Suraj Muraleedharan Feb 13 '17 at 11:21

I had to change 

spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1

to

spring.datasource.dbcp.test-while-idle=true spring.datasource.dbcp.validation-query=SELECT 1

Apparently there had been a renaming in springboot 1.4.
