前两期文章讲了一些Groovy和JMeter一些配合使用：
- 用Groovy处理JMeter断言和日志
- 用Groovy处理JMeter变量
这次再来分享一下，Groovy在JMeter中执行命令行的方法，目前我暂时想不到很多适用场景，因为的确我对JMeter并不是很熟悉，也就这两天才开始看一些资料。如果你有很好的适用场景，可以留言告诉我，一起交流交流。
- 首先新建一个简单的线程组和一个简单的请求：
- 添加JSR223 预处理程序（后置处理程序需要下一次次请求）
脚本内容：
代码语言：javascript复制log.info("jps -lv".execute().text)
"jps -lv".execute().text.eachLine{
log.error("222222222 ${it}")
}
log.info("jmeter -v".execute().text)
控制台输出：

虽然不很擅长JMeter，这些功能需求主要还是来自于测试同行同事，我顺便查一下，写一些Demo，如果你对Groovy在JMeter应用也有类似的功能需求，可以留言，我趁着JMeter知识还没在我脑海中衰退，写个Demo给你。
