性能工具之 Jmeter 通过 SpringBoot 工程启动
【摘要】 Jmeter 平时性能测试工作一般都是通过命令行在 Linux 下执行，为了锻炼自己代码与逻辑能力，想 Jmeter 是否可以通过 springboot 工程启动，周末在家尝试写一写，一写原来需要处理很多事情，才可以启动起来，起来还是有很问题需要处理，下面是相应的代码，其实网上也有，但关键的是自己有意识收集知识，到用的时候能拿来改一改就用。
背景
Jmeter 平时性能测试工作一般都是通过命令行在 Linux 下执行，为了锻炼自己代码与逻辑能力，想 Jmeter 是否可以通过 springboot 工程启动，周末在家尝试写一写，一写原来需要处理很多事情，才可以启动起来，起来还是有很问题需要处理，下面是相应的代码，其实网上也有，但关键的是自己有意识收集知识，到用的时候能拿来改一改就用。
前置条件
需要在 linux 中配置 Jmeter，并且配置 Java 环境变量：
## 编辑
vi ~/.bash_profile
# jmeter:路径 根据自己事情情况修改
JMETER_HOME=/root/tools/apache-jmeter-5.1.1
PATH=$PATH:$HOME/bin:$JMETER_HOME/bin:
export PATH
## 执行生效
source ~/.bash_profile
页面设计
运行效果
点击上传脚本，弹出对话框，点击上传，后台日志显示上传成功。
点击启动，并且读取启动日志。
点击停止。
示意图说明：
通过访问 -> 调用 JAVA 代码-> 启动 shell命令-> 启动 Jmeter -> 获取启动日志
参考代码

jmeter脚本
脚本其实也没有什么东西，只有定义好规则，这样方便替换。
小结
上面 deme 中还是一个问题没有解决就是在页面实时参看日志，目前还没实现，不过总体上实现自己想的功能。
