jmeter 源码分析

JMeter是一款开源的Java应用，用于进行性能测试和功能测试。它允许用户创建测试计划，模拟多个用户并发地访问应用程序，以测量应用程序的性能。JMeter的源码结构相当复杂，但以下是对其核心部分的简要解析：

1.入口类：NewDriver

NewDriver是整个JMeter的入口类，它的主要任务是启动JMeter测试。
该类包含了一些静态方法，如jar包的扫描、命令解析、全局参数定义以及类加载器路径操作等。

最重要的是它的main方法，该方法通过反射调用JMeter类，并启动其start方法。根据传入的参数，main方法会判断执行GUI模式还是NON_GUI模式。官方日志特别强调，若要执行发压工作，应使用命令行模式，因为这会影响发压效率和资源消耗。

2. 业务逻辑类：JMeter

JMeter类由NewDriver入口类通过反射调用，是实际的业务逻辑类。
它负责接收用户的启动参数并进行解析。
启动BeanShell服务。
JMeter类的start方法是其重点部分，因为它负责解析传入的指令，并对后续应用模式进行逻辑判断。如果未配置远程参数，启动类StandardJMeterEngine的runTest()；如果已配置远程参数，启动远程类DistributedRunner的start()，此处最终仍然调用 StandardJMeterEngine的runTest();
