如何强制Spring Boot JVM进入UTC时区?

我看到Java时区为GMT / UTC

我试过了

  • mvn spring-boot:run -Dexec.args =“-Duser.timezone = GMT”
  • mvn spring-boot:run -Dexec.args =“-Duser.timezone = UTC”
  • user.timezone=UTCconfig/application.properties
  • user.timezone=GMT
  • 在pom.xml中:

        <plugin>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-maven-plugin</artifactId>

    <configuration>

    <properties>

    <spring-boot.run.jvmArguments>-Duser.timezone=UTC</spring-boot.run.jvmArguments>

    </properties>

    </configuration>

    </plugin>

  • mvn spring-boot:运行-Dspring-boot.run.jvmArguments =“-Duser.timezone = UTC”

但它打印出来

System.out.println(TimeZone.getDefault());

sun.util.calendar.ZoneInfo [id =“ America / New_York”,offset =

-18000000,dstSavings = 3600000,useDaylight = true,transitions = 235,lastRule

= java.util.SimpleTimeZone [id = America / New_York,offset =-

18000000,dstSavings = 3600000,useDaylight = true,startYear = 0,startMode =

3,startMonth = 2,startDay = 8,startDayOfWeek = 1,startTime =

7200000,startTimeMode = 0,endMode = 3,endMonth = 10,endDay = 1, endDayOfWeek

= 1,endTime = 7200000,endTimeMode = 0]]

回答:

如果要将JVM选项从Maven Spring Boot插件传递到派生的Spring Boot应用程序,请使用spring-

boot.run.jvmArguments属性:

<properties>

<spring-boot.run.jvmArguments>-Duser.timezone=UTC</spring-boot.run.jvmArguments>

</properties>

这等效于命令行语法:

mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Duser.timezone=UTC"

或运行完全打包的Spring Boot应用程序时:

java -Duser.timezone=UTC -jar app.jar
