jmeter创建自定义java sampler往IBM MQ中发送消息的步骤
最近做的一个项目需要往IBM的MQ队列中发送消息由于jmeter没有这种Sampler所以就自己动手打造一个，记录步骤
步骤为：
- 下载需要的jar包
- 新建一个Java项目
- 导入jar包
- 编写sampler代码
- 将项目导出成jar包
- 将jar包放入{jmeterhome}/lib/ext
- 打开jmeter GUI新建一个java Sampler选择需要的请求类型即可
以下为详细步骤说明
1. 下载IBM MQ jar包，地址：https://repo1.maven.org/maven2/com/ibm/mq/com.ibm.mq.allclient/9.1.4.0/
还需要jmeter的jar包可在{jmeterhome}/lib/ext中找到
2.新建java项目一直下一步就行
3.点击file->project Structure将需要的包都导入
4.新建一个Java类继承 AbstractJavaSamplerClient 直接看源码吧

5.将项目导出成jar包 点击file->project Structure选择Artifacts
将jar包放入{jmeterhome}/lib/ext后打开jmeter
