1. Jmeter进阶三：把数据库的结果处理后保存到本地的文件

import java.util.Random;
import java.util.Arrays;
FileWriter fstream = new FileWriter("D:\\Jmeter\\测试集_rita\\添加产品.csv",false);
// 1. 设置为true时，从第2行开始插入数据；设置为false时扒枯，从第一行开始插入数据。
// 2. 设置为true时，后面运行时不会覆盖原先的数据；设置为false时，会覆盖原先的数据。

2. maven jmeter，jmeter 脚本放哪个目录下
linux环境抄还是windows环境？ 如果是linux环境，到袭bin目录下：./jmeter.sh XX.jmx(所要运行的测试脚本，没有的话，examples目录下有个) 如果有进程启动，且jmeter.log中没有错误信息就安装成功了； 如果是windows环境，双击“jmeter.bat”文件
