今天在学习Jmeter的java request，请求内容是连接redis并获取其中的一个字段值。结果在运行时报如下错误：

2018/05/24 13:08:20 ERROR - jmeter.threads.JMeterThread: Test failed! java.lang.NoClassDefFoundError: redis/clients/jedis/Jedis

    at java.net.URLClassLoader.findClass(Unknown Source)

报错原因：jmeter中缺少相应jar包。

解决方法：在网上下载jedis-2.9.0.jar后将其放到jmeter的lib目录下，重启jmeter，运行成功。
