什么是ASM ：ASM是一個用于處理Java字節(jié)碼的開源Java庫。 因此，它具有與Apache BCEL相同的目的。 由于本文假定讀者具有Java類文件格式的某些知識，因此建議在此處進(jìn)行閱讀。 那么它與BCEL有何不同？ 首先，它允許使用事件驅(qū)動的方式來操作字節(jié)碼，而無需為增加少量內(nèi)存而將整個類加載到內(nèi)存中。 其次，它沒有針對每條指令的單獨類。 相反，它直接處理操作碼，并且只包含代表每個操作碼的常量。 這在很大程度上減小了庫的大小。 因此，ASM更輕巧，更智能。 但是，ASM還具有通過將整個類加載到內(nèi)存中來處理類文件的機(jī)制，以防操作過于復(fù)雜而無法通過基于事件的處理來處理。

當(dāng)前的ASM穩(wěn)定版本是3.3。 但是4.0 RC2版本已經(jīng)發(fā)布。 因此，我將在這里討論該版本。

基于事件的處理與內(nèi)存處理 ：ASM支持事件驅(qū)動和內(nèi)存處理。 事件驅(qū)動的處理是輕量級的，但有一點限制。 另一方面，在存儲器中處理更靈活且易于使用，但它的重量更重。 內(nèi)存處理器內(nèi)部使用事件驅(qū)動處理器，就像DOM XML解析器內(nèi)部使用SAX XML解析器一樣。

下面的程序演示了偵聽類處理事件。

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時到達(dá)什么事件外，什么也不做。 目前，我們正在訪問類java.lang.String。 請注意，在Java類中，事物按順序出現(xiàn)。 例如，方法總是出現(xiàn)在字段之后。 事件也以相同的順序發(fā)生。 有關(guān)更多信息，請閱讀此處討論的類文件格式。

代碼本身非常簡單，不需要太多解釋。 我們首先擴(kuò)展ClassVisitor類，并覆蓋必要的方法。 然后，我們設(shè)置一個ClassReader并調(diào)用其accept方法，將ClassVisitor的對象作為參數(shù)傳遞。

版本4中的新功能 ：直到版本3.3為止，ClassVisitor是一個接口，因此我們必須實現(xiàn)所有方法。 為了使開發(fā)人員擺脫這種混亂局面，有一個ClassAdapter，它沒有所有方法的op實現(xiàn)，開發(fā)人員可以擴(kuò)展這些方法。 在版本4中，ClassVisitor已成為一個類，并且ClassAdapter不再存在。

注意，一些訪問者方法返回其他方法的對象。 當(dāng)遍歷特定類型的對象時，將調(diào)用那些Visitor對象的方法。 下面的示例演示如何使用MethodVisitor逐步遍歷方法的代碼。

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);}}

以下是這種情況下的輸出。

<init>()V 177main([Ljava/lang/String;)V 89 89 3 177

請注意，這些指令是直接操作碼。

生成類：在討論生成類的詳細(xì)信息之前，我將討論ASM中提供的一個很酷的東西。 它稱為ASMifier。 它是一個類，用于打印生成給定類所需的代碼。 以下示例顯示如何使用ASMifier。 該類具有主要方法，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

以下是輸出。

該代碼顯示了如何創(chuàng)建大多數(shù)類構(gòu)件。 我現(xiàn)在將解釋部分代碼。 但是，我將使用一個更簡單的類進(jìn)行演示，并且還希望添加適當(dāng)?shù)淖⑨尅?我之所以討論上述內(nèi)容，是為了防止萬一您無法創(chuàng)建特定的工件，您可以簡單地編譯一個包含該工件的類，然后使用ASMifier生成代碼以查看其創(chuàng)建方式。 我將使用以下代碼作為示例。 ClassCreationDemoMaker類創(chuàng)建一個類，該類將是對ClassCreationDemo類進(jìn)行編譯的結(jié)果。

創(chuàng)建類的基本原理是使用ClassWriter對象（即ClassVisitor），然后以適當(dāng)?shù)捻樞蛟谄渲姓{(diào)用不同的訪問方法。 在這種情況下，我們只創(chuàng)建了一個字段和三個方法。 必須創(chuàng)建構(gòu)造函數(shù)。 該代碼很容易理解。 請注意，在ClassWriter中調(diào)用visitMethod方法之后，我們已使用從其返回的MethodWriter在該方法中編寫代碼。 這里還要注意，我們已經(jīng)為每種方法手動分配了最大堆棧大小。 我們也可以在ClassWriter構(gòu)造函數(shù)中使用ClassWriter.COMPUTE_MAXS標(biāo)志來避免這樣做。

編寫課程始終是一個記憶過程。 這是因為在類中使用的常量始終需要位于常量池中，該常量池靠近該類的開頭，并且它存儲所有字段和方法名稱以及所有其他內(nèi)容。

修改類：老實說，這是ASM的亮點，因為它非常易于使用。 在本節(jié)中，我們將創(chuàng)建類ClassModifierDemo，該類將修改類ClassModificationDemo。 修飾符的工作是在每個方法調(diào)用（包括構(gòu)造函數(shù)）中插入一個打印其名稱的代碼。

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());}}

此示例是閱讀和創(chuàng)建類的組合。 在這種情況下，我們只需用自己的ClassVisitor包裝ClassWriter。 它簡單地將所有調(diào)用直接委派給ClassWriter，但visitMethod除外，后者被編寫為將ClassWriter返回的MethodVisitor用我們自己的包裝。 MethodVisitor還將直接將所有調(diào)用委派給超類，但visitCode除外，它用于插入自定義代碼。

運行該程序后，將在out目錄中使用適當(dāng)?shù)陌Y(jié)構(gòu)創(chuàng)建新版本的ClassModificationDemo。 現(xiàn)在，我們可以從out目錄運行ClassModificationDemo類，并查看結(jié)果。 它將打印何時調(diào)用哪個方法。
