使用ASM 4处理Java类文件–第一部分：世界，您好！
小编觉得挺不错的,现在分享给大家,帮大家做个参考.
什么是ASM ：ASM是一个用于处理Java字节码的开源Java库。 因此，它具有与Apache BCEL相同的目的。 由于本文假定读者具有Java类文件格式的某些知识，因此建议在此处进行阅读。 那么它与BCEL有何不同？ 首先，它允许使用事件驱动的方式来操作字节码，而无需为增加少量内存而将整个类加载到内存中。 其次，它没有针对每条指令的单独类。 相反，它直接处理操作码，并且只包含代表每个操作码的常量。 这在很大程度上减小了库的大小。 因此，ASM更轻巧，更智能。 但是，ASM还具有通过将整个类加载到内存中来处理类文件的机制，以防操作过于复杂而无法通过基于事件的处理来处理。
当前的ASM稳定版本是3.3。 但是4.0 RC2版本已经发布。 因此，我将在这里讨论该版本。
基于事件的处理与内存处理 ：ASM支持事件驱动和内存处理。 事件驱动的处理是轻量级的，但有一点限制。 另一方面，在存储器中处理更灵活且易于使用，但它的重量更重。 内存处理器内部使用事件驱动处理器，就像DOM XML解析器内部使用SAX XML解析器一样。
下面的程序演示了侦听类处理事件。
ASMHelloWorld.java
package com.geekyarticles.asm;import java.io.IOException; import java.io.InputStream; import java.util.Arrays;import org.objectweb.asm.AnnotationVisitor; import org.objectweb.asm.Attribute; import org.objectweb.asm.ClassReader; import org.objectweb.asm.ClassVisitor; import org.objectweb.asm.FieldVisitor; import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.Opcodes;public class ASMHelloWorld {/*** @param args* @throws IOException */public static void main(String[] args) throws IOException {ClassVisitor cl=new ClassVisitor(Opcodes.ASM4) {/*** Called when a class is visited. This is the method called first*/@Overridepublic void visit(int version, int access, String name,String signature, String superName, String[] interfaces) {System.out.println("Visiting class: "+name);System.out.println("Class Major Version: "+version);System.out.println("Super class: "+superName);super.visit(version, access, name, signature, superName, interfaces);}/*** Invoked only when the class being visited is an inner class*/@Overridepublic void visitOuterClass(String owner, String name, String desc) {System.out.println("Outer class: "+owner);super.visitOuterClass(owner, name, desc);}/***Invoked when a class level annotation is encountered*/@Overridepublic AnnotationVisitor visitAnnotation(String desc,boolean visible) {System.out.println("Annotation: "+desc);return super.visitAnnotation(desc, visible);}/*** When a class attribute is encountered */@Overridepublic void visitAttribute(Attribute attr) {System.out.println("Class Attribute: "+attr.type);super.visitAttribute(attr);}/***When an inner class is encountered */@Overridepublic void visitInnerClass(String name, String outerName,String innerName, int access) {System.out.println("Inner Class: "+ innerName+" defined in "+outerName);super.visitInnerClass(name, outerName, innerName, access);}/*** When a field is encountered*/@Overridepublic FieldVisitor visitField(int access, String name,String desc, String signature, Object value) {System.out.println("Field: "+name+" "+desc+" value:"+value);return super.visitField(access, name, desc, signature, value);}@Overridepublic void visitEnd() {System.out.println("Method ends here");super.visitEnd();}/*** When a method is encountered*/@Overridepublic MethodVisitor visitMethod(int access, String name,String desc, String signature, String[] exceptions) {System.out.println("Method: "+name+" "+desc);return super.visitMethod(access, name, desc, signature, exceptions);}/*** When the optional source is encountered*/@Overridepublic void visitSource(String source, String debug) {System.out.println("Source: "+source);super.visitSource(source, debug);}};InputStream in=ASMHelloWorld.class.getResourceAsStream("/java/lang/String.class");ClassReader classReader=new ClassReader(in);classReader.accept(cl, 0);}}上面的程序除了打印何时到达什么事件外，什么也不做。 目前，我们正在访问类java.lang.String。 请注意，在Java类中，事物按顺序出现。 例如，方法总是出现在字段之后。 事件也以相同的顺序发生。 有关更多信息，请阅读此处讨论的类文件格式。
代码本身非常简单，不需要太多解释。 我们首先扩展ClassVisitor类，并覆盖必要的方法。 然后，我们设置一个ClassReader并调用其accept方法，将ClassVisitor的对象作为参数传递。
版本4中的新功能 ：直到版本3.3为止，ClassVisitor是一个接口，因此我们必须实现所有方法。 为了使开发人员摆脱这种混乱局面，有一个ClassAdapter，它没有所有方法的op实现，开发人员可以扩展这些方法。 在版本4中，ClassVisitor已成为一个类，并且ClassAdapter不再存在。
注意，一些访问者方法返回其他方法的对象。 当遍历特定类型的对象时，将调用那些Visitor对象的方法。 下面的示例演示如何使用MethodVisitor逐步遍历方法的代码。
DemoClassIntructionViewer.java
package com.geekyarticles.asm;import java.io.InputStream;import org.objectweb.asm.ClassReader; import org.objectweb.asm.ClassVisitor; import org.objectweb.asm.ClassWriter; import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.Opcodes; import org.objectweb.asm.commons.InstructionAdapter;public class DemoClassInstructionViewer {public static class MethodPrinterVisitor extends ClassVisitor{public MethodPrinterVisitor(int api, ClassVisitor cv) {super(api, cv);}public MethodPrinterVisitor(int api) {super(api);}@Overridepublic MethodVisitor visitMethod(int access, String name, String desc,String signature, String[] exceptions) {System.out.println("\n"+name+desc);MethodVisitor oriMv= new MethodVisitor(4) {};//An instructionAdapter is a special MethodVisitor that//lets us process instructions easilyInstructionAdapter instMv=new InstructionAdapter(oriMv){@Overridepublic void visitInsn(int opcode) {System.out.println(opcode);super.visitInsn(opcode);}};return instMv;}}public static void main(String[] args) throws Exception{InputStream in=ASMHelloWorld.class.getResourceAsStream("/com/geekyarticles/asm/ASMHelloWorld.class");ClassReader classReader=new ClassReader(in);classReader.accept(new MethodPrinterVisitor(4), 0);}}以下是这种情况下的输出。
<init>()V 177main([Ljava/lang/String;)V 89 89 3 177请注意，这些指令是直接操作码。
生成类：在讨论生成类的详细信息之前，我将讨论ASM中提供的一个很酷的东西。 它称为ASMifier。 它是一个类，用于打印生成给定类所需的代码。 以下示例显示如何使用ASMifier。 该类具有主要方法，因此可以在命令提示符下使用。
java -cp asm-all-4.0_RC2.jar org.objectweb.asm.util.ASMifier java.lang.String>>StringDump.java以下是输出。

} }该代码显示了如何创建大多数类构件。 我现在将解释部分代码。 但是，我将使用一个更简单的类进行演示，并且还希望添加适当的注释。 我之所以讨论上述内容，是为了防止万一您无法创建特定的工件，您可以简单地编译一个包含该工件的类，然后使用ASMifier生成代码以查看其创建方式。 我将使用以下代码作为示例。 ClassCreationDemoMaker类创建一个类，该类将是对ClassCreationDemo类进行编译的结果。
ClassCreationDemo.java
package com.geekyarticles.asm;public class ClassCreationDemo {private int version;public int getVersion() {return version;}public void setVersion(int version) {this.version = version;}@Overridepublic String toString(){return "ClassCreationDemo: "+version;} }ClassCreationDemoMaker.java
package com.geekyarticles.asm; import java.io.DataOutputStream; import java.io.FileOutputStream; import static org.objectweb.asm.Opcodes.*; import org.objectweb.asm.*;public class ClassCreationDemoMaker {public static byte[] dump () throws Exception {//ClassWriter is a class visitor that generates the code for the classClassWriter cw = new ClassWriter(0);FieldVisitor fv;MethodVisitor mv;//Start creating the class. cw.visit(V1_6, ACC_PUBLIC + ACC_SUPER, "com/geekyarticles/asm/ClassCreationDemo", null, "java/lang/Object", null);{//version fieldfv = cw.visitField(ACC_PRIVATE, "version", "I", null, null);fv.visitEnd();}{//Implementing the constructormv = cw.visitMethod(ACC_PUBLIC, "<init>", "()V", null, null);mv.visitCode();mv.visitVarInsn(ALOAD, 0);mv.visitMethodInsn(INVOKESPECIAL, "java/lang/Object", "<init>", "()V");mv.visitInsn(RETURN);mv.visitMaxs(1, 1);mv.visitEnd();}{//getVersion Methodmv = cw.visitMethod(ACC_PUBLIC, "getVersion", "()I", null, null);mv.visitCode();mv.visitVarInsn(ALOAD, 0);mv.visitFieldInsn(GETFIELD, "com/geekyarticles/asm/ClassCreationDemo", "version", "I");mv.visitInsn(IRETURN);mv.visitMaxs(1, 1);mv.visitEnd();}{//setVersion Methodmv = cw.visitMethod(ACC_PUBLIC, "setVersion", "(I)V", null, null);mv.visitCode();mv.visitVarInsn(ALOAD, 0);mv.visitVarInsn(ILOAD, 1);mv.visitFieldInsn(PUTFIELD, "com/geekyarticles/asm/ClassCreationDemo", "version", "I");mv.visitInsn(RETURN);mv.visitMaxs(2, 2);mv.visitEnd();}{//toString methodmv = cw.visitMethod(ACC_PUBLIC, "toString", "()Ljava/lang/String;", null, null);mv.visitCode();mv.visitTypeInsn(NEW, "java/lang/StringBuilder");mv.visitInsn(DUP);mv.visitLdcInsn("ClassCreationDemo: ");mv.visitMethodInsn(INVOKESPECIAL, "java/lang/StringBuilder", "<init>", "(Ljava/lang/String;)V");mv.visitVarInsn(ALOAD, 0);mv.visitFieldInsn(GETFIELD, "com/geekyarticles/asm/ClassCreationDemo", "version", "I");mv.visitMethodInsn(INVOKEVIRTUAL, "java/lang/StringBuilder", "append", "(I)Ljava/lang/StringBuilder;");mv.visitMethodInsn(INVOKEVIRTUAL, "java/lang/StringBuilder", "toString", "()Ljava/lang/String;");mv.visitInsn(ARETURN);mv.visitMaxs(3, 1);mv.visitEnd();}cw.visitEnd();return cw.toByteArray();}public static void main(String [] args) throws Exception{DataOutputStream dout=new DataOutputStream(new FileOutputStream("ClassCreationDemo.class"));dout.write(dump());dout.flush();dout.close();} }创建类的基本原理是使用ClassWriter对象（即ClassVisitor），然后以适当的顺序在其中调用不同的访问方法。 在这种情况下，我们只创建了一个字段和三个方法。 必须创建构造函数。 该代码很容易理解。 请注意，在ClassWriter中调用visitMethod方法之后，我们已使用从其返回的MethodWriter在该方法中编写代码。 这里还要注意，我们已经为每种方法手动分配了最大堆栈大小。 我们也可以在ClassWriter构造函数中使用ClassWriter.COMPUTE_MAXS标志来避免这样做。
编写课程始终是一个记忆过程。 这是因为在类中使用的常量始终需要位于常量池中，该常量池靠近该类的开头，并且它存储所有字段和方法名称以及所有其他内容。
修改类：老实说，这是ASM的亮点，因为它非常易于使用。 在本节中，我们将创建类ClassModifierDemo，该类将修改类ClassModificationDemo。 修饰符的工作是在每个方法调用（包括构造函数）中插入一个打印其名称的代码。
ClassModifierDemo.java
package com.geekyarticles.asm;import java.io.DataOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream;import org.objectweb.asm.ClassReader; import org.objectweb.asm.ClassVisitor; import org.objectweb.asm.ClassWriter; import org.objectweb.asm.MethodVisitor; import org.objectweb.asm.Opcodes;public class ClassModifierDemo {public static class ModifierMethodWriter extends MethodVisitor{private String methodName;public ModifierMethodWriter(int api, MethodVisitor mv, String methodName) {super(api, mv);this.methodName=methodName;}//This is the point we insert the code. Note that the instructions are added right after//the visitCode method of the super class. This ordering is very important.@Overridepublic void visitCode() {super.visitCode();super.visitFieldInsn(Opcodes.GETSTATIC, "java/lang/System", "out", "Ljava/io/PrintStream;");super.visitLdcInsn("method: "+methodName);super.visitMethodInsn(Opcodes.INVOKEVIRTUAL, "java/io/PrintStream", "println", "(Ljava/lang/String;)V");}}//Our class modifier class visitor. It delegate all calls to the super class//Only makes sure that it returns our MethodVisitor for every methodpublic static class ModifierClassWriter extends ClassVisitor{private int api;public ModifierClassWriter(int api, ClassWriter cv) {super(api, cv);this.api=api;}@Overridepublic MethodVisitor visitMethod(int access, String name, String desc,String signature, String[] exceptions) {MethodVisitor mv= super.visitMethod(access, name, desc, signature, exceptions);ModifierMethodWriter mvw=new ModifierMethodWriter(api, mv, name);return mvw;}}public static void main(String[] args) throws IOException {InputStream in=ASMHelloWorld.class.getResourceAsStream("/com/geekyarticles/asm/ClassModificationDemo.class");ClassReader classReader=new ClassReader(in);ClassWriter cw=new ClassWriter(ClassWriter.COMPUTE_MAXS);//Wrap the ClassWriter with our custom ClassVisitorModifierClassWriter mcw=new ModifierClassWriter(Opcodes.ASM4, cw);classReader.accept(mcw, 0);//Write the output to a class fileFile outputDir=new File("out/com/geekyarticles/asm");outputDir.mkdirs();DataOutputStream dout=new DataOutputStream(new FileOutputStream(new File(outputDir,"ClassModificationDemo.class")));dout.write(cw.toByteArray());}}ClassModificationDemo.java
package com.geekyarticles.asm;public class ClassModificationDemo {private int version;public int getVersion() {return version;}public void setVersion(int version) {this.version = version;}@Overridepublic String toString(){return "ClassCreationDemo: "+version;}public static void main(String[] args) {System.out.println(new ClassModificationDemo());}}此示例是阅读和创建类的组合。 在这种情况下，我们只需用自己的ClassVisitor包装ClassWriter。 它简单地将所有调用直接委派给ClassWriter，但visitMethod除外，后者被编写为将ClassWriter返回的MethodVisitor用我们自己的包装。 MethodVisitor还将直接将所有调用委派给超类，但visitCode除外，它用于插入自定义代码。
运行该程序后，将在out目录中使用适当的包结构创建新版本的ClassModificationDemo。 现在，我们可以从out目录运行ClassModificationDemo类，并查看结果。 它将打印何时调用哪个方法。
