Enaium的博客

首发于Enaium的个人博客使用树API来生成一个类public static void main(String[] args) { ClassWriter classWriter = new ClassWriter(ClassWriter.COMPUTE_MAXS); ClassNode classNode = new ClassNode(); classNode.visit(V1_8, ACC_PUBLIC, "cn/enaium/learn/asm/learn6/Lear

首发于Enaium的个人博客测试类，需要混淆这里所有的字符串，上一期我们学习了如果插入一个常量，那么拦截插入常量的时候判断是不是字符串，如果是就混淆它。public class Learn5Test { private final String name = "Enaium"; private Learn5Test() { render(name); } private void render() { System.out.print

首发于Enaium的个人博客这期我们要创建一个对象和数组。MethodVisitor methodVisitor = classWriter.visitMethod(ACC_PUBLIC, "<init>", "()V", null, null);methodVisitor.visitTypeInsn(NEW, "java/lang/String");//插入一个对象，操作码是NEW，类型是String。methodVisitor.visitLdcInsn("Enaium");//插入

首发于Enaium的个人博客可以委托一个ClassWriter。public class MyClassVisitor extends ClassVisitor { public MyClassVisitor(ClassWriter classWriter) { super(ASM5, classWriter); }}这样就可以把读取到的类转换为二进制文件了。ClassReader classReader = new ClassReader(Learn3Test

首发于Enaium的个人博客public class Learn2 { public static void main(String[] args) throws NoSuchMethodException, InvocationTargetException, IllegalAccessException { ClassWriter classWriter = new ClassWriter(ClassWriter.COMPUTE_MAXS); classWri

首发于Enaium的个人博客ASM是一种通用Java字节码操作和分析框架，它可以用于修改现有的class文件或动态生成class文件。直接进入主题，分析这个类。public class Learn1Test { public boolean aBoolean = false; public void render() { System.out.println("Hello ASM"); }}先创建一个MyClassVisitor类，继承ClassVis
