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 = ;

        String randomstring = "";

        for (int i=; i<string_length; i++) {

            Random randomGenerator = new Random();

            int randomInt = randomGenerator.nextInt(chars.length());

            randomstring += chars.substring(randomInt,randomInt+);

        }

        return randomstring;

    }

    public static void main(String[] args) {

        String result=new randStr().random_len();

        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();

        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 = ;

        String randomstring = "";

        for (int i=; i<string_length; i++)

        {

            Random randomGenerator = new Random();

            int randomInt = randomGenerator.nextInt(chars.length());

            randomstring += chars.substring(randomInt,randomInt+);

        }

        return randomstring;

    }

String result =random_len();

log.info(result);
