是否可以使用JMeter生成UUID v1？

我阅读了JMeter的手册，发现JMeter有一个uuid（）函数。它允许为JMeter测试生成UUID类型4。是否可以在JMeter中生成UUIDv1，或者可能存在某个插件。

在JMeter中，您可以添加JSR 223采样器选择Java语言并执行UUID版本1的Java代码：

 String timeuuid = com.datastax.driver.core.utils.UUIDs.timeBased().toString();

然后将其添加到Jmeter变量：

 vars.put("myUUID", timeuuid);

我建议采取以下步骤：

下载（例如从）并将.jar放到某个地方

重新启动JMeter以拾取.jar

完成后，您应该能够使用以下类似工具生成UUIDv1：

首先，我们将生成64个最低和最高有效位作为长值：

private static long get64LeastSignificantBitsForVersion1() {
    Random random = new Random();
    long random63BitLong = random.nextLong() & 0x3FFFFFFFFFFFFFFFL;
    long variant3BitFlag = 0x8000000000000000L;
    return random63BitLong + variant3BitFlag;
}
 
private static long get64MostSignificantBitsForVersion1() {
    LocalDateTime start = LocalDateTime.of(1582, 10, 15, 0, 0, 0);
    Duration duration = Duration.between(start, LocalDateTime.now());
    long seconds = duration.getSeconds();
    long nanos = duration.getNano();
    long timeForUuidIn100Nanos = seconds * 10000000 + nanos * 100;
    long least12SignificatBitOfTime = (timeForUuidIn100Nanos & 0x000000000000FFFFL) >> 4;
    long version = 1 << 12;
    return 
      (timeForUuidIn100Nanos & 0xFFFFFFFFFFFF0000L) + version + least12SignificatBitOfTime;
}

private static long get64LeastSignificantBitsForVersion1() {
    Random random = new Random();
    long random63BitLong = random.nextLong() & 0x3FFFFFFFFFFFFFFFL;
    long variant3BitFlag = 0x8000000000000000L;
    return random63BitLong + variant3BitFlag;
}
 
private static long get64MostSignificantBitsForVersion1() {
    LocalDateTime start = LocalDateTime.of(1582, 10, 15, 0, 0, 0);
    Duration duration = Duration.between(start, LocalDateTime.now());
    long seconds = duration.getSeconds();
    long nanos = duration.getNano();
    long timeForUuidIn100Nanos = seconds * 10000000 + nanos * 100;
    long least12SignificatBitOfTime = (timeForUuidIn100Nanos & 0x000000000000FFFFL) >> 4;
    long version = 1 << 12;
    return 
      (timeForUuidIn100Nanos & 0xFFFFFFFFFFFF0000L) + version + least12SignificatBitOfTime;
}

public static UUID generateType1UUID() {
 
    long most64SigBits = get64MostSignificantBitsForVersion1();
    long least64SigBits = get64LeastSignificantBitsForVersion1();
 
    return new UUID(most64SigBits, least64SigBits);
}
