My Application.properties is:

spring.main.web-application-type=none
spring.datasource.url=jdbc:oracle:thin:@192.168.92.5:1521/ORADB
spring.datasource.username=magerwa
spring.datasource.password=butare
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

I tried this to configure like this:

   @PostConstruct
        public void init() {
            // Setting Spring Boot SetTimeZone
            TimeZone.setDefault(TimeZone.getTimeZone("+00:00"));
        }

but none worked for me
