Jmeter not found in class'org.json.JSONObject 问题

前景：公司有银行的项目要进行压测，但是接口有近视RSA加密，需发送签名，只能使用java编写原生接口脚本打包成jar使用BeanShell Sampler去调用发送请求。在使用的过程中遇到了如下问题。

刚开始和开发一起解决，因开发未接触Jmeter及Jmeter报错信息提示有限，极其不情愿苦逼的帮我看了下之后潇洒离去，只能自力更生，在Jmeter坑比有限的报错信息下，花了一星期才解决，所以将此问题记录。（归根结底还是自己的基础不好）

Typed variable declaration : Class: JSONObject not found in namespace

jmeter Typed variable declaration : Command not found: sendPost( com.alibaba.fastjson.JSONObject, java.lan

Typed variable declaration : Error in method invocation: Static method fromObject ( java.lang.String ) not found in class'org.json.JSONObject'

遇到的两个问题：

1.一直报没找到包的错误。嗯哼！一星期里，我把所有导包方式4种都找到了（保证万无一失）

1）将需要的包导入目录下D:\apache-jmeter-3.3\lib\ext

2）将需要的包导入目录下D:\apache-jmeter-3.3\bin

3）在测试计划种添加此jar包

4）在BeanShell Sampler里import

2一个坑，类是私有的，需改为public

3（以下两个是提醒，基本楼上两个就可以解决。）避免有空函数，注意空格。

4避免第一点路径有老旧的jar包。在ecplise中的httpclient jar包版本要于jmeter中的版本一直或是比jmeter中的高，否则会报错java.lang.NoSuchFieldError: INSTANCE。

第一个看的是这个狗*的博客https://www.jianshu.com/p/240e929323a6，并没有相关导包的操作（深恶痛绝，妈个鸡）

下面这个还不错。不建议看。还未看留着慢慢看（太长了不看）。
