1、先完成jmeter脚本编写,具体怎么写此处不再详述,可以参考其他文档、
2、有时你会发现jmeter脚本执行后,有些响应信息你需要提取到文件中,以便后续使用;
怎么实现呢?个人思路就是,先写个java类,这个类的功能就是参数保存到指定文件;
然后进行java请求,保存该文件
具体步骤:
2.1 idea打开创建一个java项目,添加依赖的jmeter jar包
2.2 创建 OutputService 和PerformenceTest两个类
1 import java.io.File;
2 import java.io.PrintWriter;

7 public class OutputService {
8 public static void output(String filename,String csName,String csPwd,String ghsName,String ghsPwd,String ywyName,String ywyPwd) throws Exception{
9 PrintWriter out=new PrintWriter(new File(filename));
10 out.write("所有平台注册账号:"+"\r\n");
11 out.write("超市注册账号:"+"\r\n"+csName+" "+csPwd+"\r\n"+"供货商注册账号:"+"\r\n"+ghsName+" "+ghsPwd+"\r\n"+"业务员注册账号:"+"\r\n"+ywyName+" "+ywyPwd+"\r\n");
12 out.close();
13
14 }

2.3 打jar包,步骤如图所示
2.4 然后把打好的JavaSampler.jar包cp到jmeter目录\lib\ext下
3、重启jmeter,加载刚导入的jar包
4、创建java请求,选择jar包的类名称,参数会自动加载出来,且默认值均为0,然后给各个参数赋值,下图是我给参数化了,也可以写具体的值
执行该请求,参数值会保存至指定的文件
执行结果如下图所示
