如何在Jmeter变量中存储数组值? [英] How to store array values in Jmeter variables?

问题描述

我有一个CSV文件，其中包含我使用Bean Shell脚本读取的数据，并根据该数据填充ArrayList.下面是代码.

I have a CSV file containing data which I read using a Bean Shell script and populate an ArrayList based upon it.Below is the code for it.

//Populate Beanshell script
import java.text.*;
import java.io.*;
import java.util.*;

ArrayList strList = new ArrayList();    

try {
File file = new File("path/to/csv");

if (!file.exists()) {
    throw new Exception ("ERROR: file not found");
}

BufferedReader bufRdr = new BufferedReader(new FileReader(file));
String line = null;

while((line = bufRdr.readLine()) != null) {
    strList.add(line);
}

bufRdr.close();   
}
catch (Exception ex) {
IsSuccess = false; 
log.error(ex.getMessage());
System.err.println(ex.getMessage());
}
catch (Throwable thex) {
System.err.println(thex.getMessage());
}

现在我想以随机方式利用这些数据，所以我正在尝试使用类似的东西

Now I want to utilize this data in a random manner so I am trying to use something like this

//Consumer bean shell script
//Not able to access strList since vars.put cannot store an object
Random rnd = new java.util.Random(); 
vars.put("TheValue",strList.get(rnd.nextInt(strList.size())));

但是我无法做到这一点，因为在vars.put中，我无法存储数组或列表，只能存储基本类型.因此，我无法从另一个BeanShell访问填充函数的ArrayList.脚本.

But I am unable to do this because in vars.put I cannot store an array or a list,I can only store only primitive types.So there is no way in which I can access the populate function's ArrayList from an another BeanShell script.

在这种情况下，如何实现随机化，因为从性能的角度来看，每次都调用填充函数是不好的.

How do I achieve randomization in this scenario since calling populate function each and every time is not good from a performance point of view.

推荐答案

我建议使用 bsh.共享名称空间，这样您就可以存储任何Java对象，并在需要时甚至可以从不同的线程组访问它.

I would recommend using bsh.shared namespace, this way you will be able to store any Java object and access it even from different Thread Groups if needed.

JMeter特定的示例在官方文档的共享变量章

JMeter-specific example is in the official documentation, in Sharing Variables chapter

在第一个脚本的结尾:

bsh.shared.strList = strList;

在第二个脚本的开头:

List strList = bsh.shared.strList;


Random rnd = new java.util.Random(); 
vars.put("TheValue",strList.get(rnd.nextInt(strList.size())));
