我的设置： 我在Linux上使用JMeter 5.2.1和OpenJDK 8（
OpenJDK版本“1.8.0_252”
）（
version 5.6.15-arch1-1
）

（与Ubuntu 20.04上的JMeter 5.3在CLI模式下运行时得到的结果相同）

根据HTTP/2插件的要求，我在我的
jmeter
启动脚本的顶部添加了以下行：

JVM_ARGS="-Xbootclasspath/p:/opt/jmeter/lib/alpn-boot-8.1.13.v20181017.jar"
如何解决或调试此问题

更新： 我发现，正如上面提到的，只要我使用
alpn boot
，我就有了与常规HTTP请求相同的行为，因此该库似乎存在问题。在上有一个jetty alpn版本与Java版本的映射表，它当前不包含我的Java版本

说

该表仅显示了到OpenJDK 8u242的映射，OpenJDK 8u242是需要ALPN引导jar的最后一个版本

但是如果我在没有alpn参数的情况下启动JMeter，我会看到如下结果（HTTP/2和HTTPS）：

正如我发现的，OpenJDK 8u252和Jetty 9.4.26（随JMeter一起提供）的组合不兼容

ALPN API已经被后移植到Java 8u252和Jetty 9.4.28，并且不再需要
ALPN引导

更多信息：

将Jetty库更新至9.4.28有助于：


    

  • 从和下载文件
    • 

  • 将
    jmeter/lib
    中的
    jetty*-9.4.26*
    文件替换为下载存档中的9.4.28对应文件
    • 


更新：文件列表


lib/jetty-alpn-client-9.4.28.v20200408.jar
lib/jetty-alpn-openjdk8-client-9.4.28.v20200408.jar

lib/jetty-io-9.4.28.v20200408.jar
lib/jetty-util-9.4.28.v20200408.jar



我想我发现了一个问题：“你需要Jetty 9.4.28与8u252一起工作。”-我成功后将作为答案发布Jetty 9.4.28+中没有Jetty alpn客户端JAR。你对他们做了什么？远离的？还是保留？在这两种情况下，我仍然无法解决与ALPN相关的问题。JDK 1.8.0_265，JMeter 5.3.0，JMeter HTTP2插件1，Jetty 9.4.31。@martin-g我用文件列表和第二个下载链接更新了答案。我记得我首先从不同的位置下载了它，然后在
jetty distribution
中找到了其余的文件……谢谢你，Fabian！ALPN客户端jar（jetty-ALPN-client-9.4.31.v20200723.jar和jetty-ALPN-openjdk8-client-9.4.31.v20200723.jar）不是jetty发行版的一部分，我认为它们已经不再发布了。我已经从Maven Central下载了它们，现在一切都好了！
