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;
 3 
 4 /**

 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     }
15 
16 }
OutputService
 1 package com.test;

 3 import org.apache.jmeter.config.Arguments;
 4 import org.apache.jmeter.protocol.java.sampler.JavaSamplerClient;
 5 import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
 6 import org.apache.jmeter.samplers.SampleResult;

12 public class PerformenceTest implements JavaSamplerClient {
13     private SampleResult results;
14     //private String orderNumber;
15     private String csName;
16     private String csPwd;

34 
35         JavaSamplerContext arg0 = new JavaSamplerContext(params);
36         PerformenceTest test = new PerformenceTest();
37         test.setupTest(arg0);
38         test.runTest(arg0);
39         test.teardownTest(arg0);
40     }
41     // 设置传入的参数,可以设置多个,已设置的参数会显示到Jmeter的参数列表中

50         params.addArgument("ywyName", "0");//设置参数,并赋予默认值0
51         params.addArgument("ywyPwd","0");
52         return params;
53     }
54 
55 
56     // 初始化方法,实际运行时每个线程仅执行一次,在测试方法运行前执行
57     public void setupTest(JavaSamplerContext arg0) {
58         results = new SampleResult();
59     }
60 
61 
62     // 测试执行的循环体,根据线程数和循环次数的不同可执行多次
63     @Override
64     public SampleResult runTest(JavaSamplerContext arg0) {
65         // orderNumber = arg0.getParameter("orderNumber"); // 获取在Jmeter中设置的参数值

70         ywyName=arg0.getParameter("ywyName");
71         ywyPwd=arg0.getParameter("ywyPwd");
72         filename = arg0.getParameter("filename"); // 获取在Jmeter中设置的参数值
73         results.sampleStart();// jmeter 开始统计响应时间标记
74         try {
75             OutputService test = new OutputService();
76             test.output(filename,csName,csPwd,ghsName,ghsPwd,ywyName,ywyPwd);
77             results.setSuccessful(true);
78 // 被测对象调用
79         } catch (Throwable e) {
80             results.setSuccessful(false);
81             e.printStackTrace();
82         } finally {
83             results.sampleEnd();// jmeter 结束统计响应时间标记
84         }
85         return results;
86     }
87 
88 
89     // 结束方法,实际运行时每个线程仅执行一次,在测试方法运行结束后执行
90     public void teardownTest(JavaSamplerContext arg0) {
91     }
92 
93 }
PerformenceTest

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
