JMeter通过自定义jar调用和BeanShell源码

自定义jar包引用

原始java代码，代码的作用的是根据指定的字符串，生成执行长度的随机字符串

package com;
import java.util.Random;
public class randStr {

    public String random_len(int length){
        String chars= "ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz0123456789";
        int string_length = 8;
        String randomstring = "";
        for (int i=0; i<string_length; i++) {
            Random randomGenerator = new Random();
            int randomInt = randomGenerator.nextInt(chars.length());
            randomstring += chars.substring(randomInt,randomInt+1);
        }
        return randomstring;
    }

    public static void main(String[] args) {
        String result=new randStr().random_len(8);
        System.out.println(result);
    }

}

通过main函数，脚本调试成功

然后通过eclipse工具将刚才的代码导出成jar包

注意：导出jar包时，一定要将main主函数删除

    public static void main(String[] args) {
        String result=new randStr().random_len(8);
        System.out.println(result);
    }

将randStr.jar包导入

开始在BeanShell中引用

通过Beanshell代码引用

import java.util.Random;
public String random_len(int length)
    {
        String chars= "ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz0123456789";
        int string_length = 16;
        String randomstring = "";
        for (int i=0; i<string_length; i++)
        {
            Random randomGenerator = new Random();
            int randomInt = randomGenerator.nextInt(chars.length());
            randomstring += chars.substring(randomInt,randomInt+1);
        }
        return randomstring;
    }

String result =random_len(16);
log.info(result);
