Java逆向基础之十六.打印所有类名

破解 java 逆向 2018/09/16

本文于1989天之前发表，文中内容可能已经过时。

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

public class ClassNameTransformer implements ClassFileTransformer {

    @Override
    public byte[] transform(ClassLoader loader, String className, Class<?> classBeingRedefined, ProtectionDomain protectionDomain, byte[] classfileBuffer) throws IllegalClassFormatException {
        System.out.println(className);

}

Manifest-Version: 1.0
Premain-Class: com.vvvtimes.demo.agent.ClassNameAgent
Can-Redefine-Classes: true

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

1
java -javaagent:ClassNameAgent.jar -jar DynamicGenerateClass.jar

执行结果
