我希望通过jmeter插件管理器安装的jmeter扩展向kafka使用者发送动态生成的消息，从而对kafka进行负载测试。
我的Kafka是配置，设置和运行完美。我按照以下说明设置并运行kafka测试计划，但每次设置并运行时，日志中都会出现以下错误：

所以，我得到的错误是它找不到 org/apache/log4j/logger ，但我不知道如何解决这个问题。我看了别人遇到的其他已知问题，看看它们是否与我的相似，但没有结果。我想我的测试计划可能写错了，但我找不到任何问题。关于我做错了什么有什么建议吗？

java.lang.classnotfoundexception此异常表示在类路径上找不到该类。这表明我们试图加载类定义，而类路径上不存在该类。
尝试添加log4jjar。
如果它是一个maven项目，您可以添加以下依赖项，随时更改为适当的版本。

<dependency>
   <groupId>log4j</groupId>
   <artifactId>log4j</artifactId>
   <version>1.2.15</version>
</dependency>

如果存在版本冲突，这也可能发生，因为log4jjar可能捆绑在另一个jar中，请尝试找出并排除log4jjar。

<dependency>
    <groupId>org.apache.kafka</groupId>
    <artifactId>kafka_2.10</artifactId>
    <version>0.8.1.1</version>
    <exclusions>
        <exclusion>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>

我发现了问题所在。jmeter在它的 lib 文件夹，当下载并放入所述文件夹时，测试运行没有问题。
