jmeter之Java request報錯：java.lang.NoClassDefFoundError: redis/clients/jedis/Jedis

今天在學習Jmeter的java request，請求內容是連接redis並獲取其中的一個字段值。結果在運行時報如下錯誤：

2018/05/24 13:08:20 ERROR - jmeter.threads.JMeterThread: Test failed! java.lang.NoClassDefFoundError: redis/clients/jedis/Jedis
    at cn.testfan.redis.RedisJavaTest.setupTest(RedisJavaTest.java:36)

    at java.net.URLClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)

報錯原因：jmeter中缺少相應jar包。

解決方法：在網上下載jedis-2.9.0.jar后將其放到jmeter的lib目錄下，重啟jmeter，運行成功。
