问题描述
近期使用Jmeter时发现了一个非常奇怪的问题就是Jmeter是可以正常使用运行脚本但是在Log viewer中确没有任何日志如下图 问题排查过程
真是百思不得其解啊在网上各种获取资料大多数都是说跟Jmeter的log日志配置有关系按照指引 真是一顿操作猛如虎仔细一看原地杵啊 没有任何效果 然后重新解压了同版本5.4.1的jmeter保证jmeter 是干净的没有出现任何问题排除了jmeter版本的bug。
这时我又重新启动了我出现问题的jmeter偶然发现控制台报错信息如下

解决办法
此时问题真像大白是引入了第三方jar包产生了版本冲突该问题是我之前压测mq引入的jar包当时压测是可以正常执行的所以就一直没太注意这个问题。。。
所以大家在使用Jmeter引入第三方jar包进行测试时一旦发现了一些莫名其妙的问题可以排查一下是不是自己引入的jar包造成的版本冲突
