Spring PostMethod returns the date from UTC

I have a simple app with rest сontroller.The app runs in Docker.

@RestController
@Slf4j
public class TimeTestController {
    @PostMapping("/time-test")
    public @ResponseBody TimeTest timeTest (@RequestBody TimeTest timeTest) {
        log.info("request {}",  timeTest);
        TimeTest time = new TimeTest();
        time.setDate(timeTest.getDate());
        return time;
    }
}

And simple class like this

@Data
@AllArgsConstructor
@NoArgsConstructor
public class TimeTest {
    private String id;
    private Date date;
}

I pass the date with the time zone to the controller 2020-12-07T19:54:25.860+0100. However, in the method, the date is printed with timeZone UTC 2020-12-07T18:54:25.860+0000. And it also returns with timeZone UTC, but I need to return with the same zone as it came. How can I fix this?

Java's Date a) doesn't support timezone & b) shouldn't be used if you are on Java 8+. I'd suggest using OffsetDateTime here instead.

Assuming you are using Jackson w/ Spring Boot, in addition to the web starter make sure to include jackson-datatype-jsr310 as a dependency. When Boot detects it on the classpath, it will automatically configure Jackson's JavaTimeModule, which supports the new Java8 Date/Time APIs.

Good luck!

It seems your JVM's time zone is UTC. The problem with implementations based on java.util.Date is that in most cases, they display the date-time in the JVM's time zone. I recommend you use the modern date-time API. Since your date-time string, 2020-12-07T19:54:25.860+0100 has zone offset information, the most appropriate class to use is OffsetDateTime.

@RestController
@Slf4j
public class TimeTestController {
    @PostMapping("/time-test")
    public @ResponseBody TimeTest timeTest (@RequestBody TimeTest timeTest) {
        log.info("request {}",  timeTest);
        TimeTest time = new TimeTest();
        time.setOdt(timeTest.getDate());// Change timeTest.getDate() to return OffsetDateTime
        return time;
    }
}

and then in the class, TimeTest

@Data
@AllArgsConstructor
@NoArgsConstructor
public class TimeTest {
    private String id;
    private OffsetDateTime odt;
}
