在 Java SE 5 及其后续版本当中，开发者可以在一个普通 Java 程序（带有 main 函数的 Java 类）运行时，通过 –javaagent 参数指定一个特定的 jar 文件（包含 Instrumentation 代理）来启动 Instrumentation 的代理程序。在类的字节码载入jvm前会调用ClassFileTransformer的transform方法，从而实现修改原类方法的功能
使用方法如下，在premain方法中使用如下语句
1
| inst.addTransformer(new ClassNameTransformer());
|
其中ClassNameTransformer实现了ClassFileTransformer，并重写transform方法
下面的例子使用这个方式输出所有类名
新建名为ClassNameAgent的项目，结构如下

导出为ClassNameAgent.jar
将动态生成类的博文中的代码导出可运行jar，命名为DynamicGenerateClass.jar
放到同一目录执行命令

| java -javaagent:ClassNameAgent.jar -jar DynamicGenerateClass.jar
