如何强制Spring Boot JVM进入UTC时区? [英] How do I force a Spring Boot JVM into UTC time zone?

问题描述

我看到了将Java时区强制设置为GMT/UTC

我尝试过

• mvn spring-boot:run -Dexec.args =-Duser.timezone = GMT"
• mvn spring-boot:run -Dexec.args =-Duser.timezone = UTC"
config/application.properties 中的
• user.timezone=UTC
• user.timezone=GMT

• 在pom.xml中:

• mvn spring-boot:run -Dexec.args="-Duser.timezone=GMT"
• mvn spring-boot:run -Dexec.args="-Duser.timezone=UTC"
• user.timezone=UTC in config/application.properties
• user.timezone=GMT

• In the pom.xml:

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

但它会打印出来

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，偏移量= -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]]

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]]

Spring Boot 1.5.19，Java 8

Spring Boot 1.5.19, Java 8

推荐答案

使用

Use spring-boot.run.jvmArguments property if you want to pass JVM options from Maven Spring Boot Plugin to forked Spring Boot application:

<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:

or when running a fully packaged Spring Boot application:

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