以前值是读过一遍jdk和cglib的代理，时间长了，都忘记入口在哪里了，值是记得其中的一些重点了，今天写一篇博客，当作是笔记。和以前一样，关键代码，我会用红色标记出来。

首先，先列出我的jdk代理对象和测试代码：

package com.example.gof.proxy;

/**
* 买车接口
*/
public interface BuyCard {
void buycard();
}

package com.example.gof.proxy;

import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;

public class BuyCardDynamicProxy implements InvocationHandler {
private Object object;

public BuyCardDynamicProxy(final Object object) {  
    this.object = object;  
}

/\*\*  
 \*  代理回调的方法，反编译后可以看到调用的是这段代码:super.h.invoke(this, m3, null);  
 \*  m3 = Class.forName("com.example.gof.proxy.BuyCard").getMethod("buycard", new Class\[0\]);  
 \* @param proxy 代理  
 \* @param method  代理调用的而方法  
 \* @param args 调用的方法的参数  
 \* @return  
 \* @throws Throwable  
 \*/  
@Override  
public Object invoke(Object proxy, Method method, Object\[\] args) throws Throwable {  
    System.out.println("动态代理，买车前");  
    Object res= method.invoke(object,args);  
    System.out.println("动态代理，洗刷刷");  
    return res;  
}  

}

package com.example.gof.proxy;

import com.example.gof.proxy.impl.BuyCardImpl;
import sun.misc.ProxyGenerator;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.lang.reflect.Proxy;

public class TestBuyCardDynamicProxy {
public static void main(String[] args) throws IOException {
BuyCard buyCard = new BuyCardImpl();
BuyCard buyCardProxy = (BuyCard) Proxy.newProxyInstance(BuyCard.class.getClassLoader(),
new Class[]{BuyCard.class}, new BuyCardDynamicProxy(buyCard));
buyCardProxy.buycard();

//下面这段是用于生成字节码分析的
// byte[] classFile= ProxyGenerator.generateProxyClass("$Proxy", new Class[]{BuyCard.class});
// File file=new File("D:\\java\\GoF\\src\\main\\java\\com\\example\\gof\\proxy/$Proxy.class");
// FileOutputStream os=new FileOutputStream(file);
// os.write(classFile);
// os.flush();
// os.close();

}  

}

跟踪进去，查看 Proxy.newProxyInstance(BuyCard.class.getClassLoader() 这个方法，代码如下：

/**

* that dispatches method invocations to the specified invocation
* handler.

    } catch (NoSuchMethodException e) {  
        throw new InternalError(e.toString(), e);  
    }  
}

/\*\*

上面这个代码当初看了很久，怎么到proxyClassCache.get(loader, interfaces); 就已经生成了代理对象呢。后来百度下，才知道proxyClassCache9 这个对象调用构造参数时候，就生成了二进制文件，核心代码也在这里。继续往下看

继续跟进生成二进制字节码的方法：ProxyGenerator.generateProxyClass( proxyName, interfaces, accessFlags)

public static byte[] generateProxyClass(final String var0, Class[] var1, int var2) {
ProxyGenerator var3 = new ProxyGenerator(var0, var1, var2);
final byte[] var4 = var3.generateClassFile();
if (saveGeneratedFiles) {
AccessController.doPrivileged(new PrivilegedAction() {
public Void run() {
try {
int var1 = var0.lastIndexOf(46);
Path var2;
if (var1 > 0) {
Path var3 = Paths.get(var0.substring(0, var1).replace('.', File.separatorChar));
Files.createDirectories(var3);
var2 = var3.resolve(var0.substring(var1 + 1, var0.length()) + ".class");
} else {
var2 = Paths.get(var0 + ".class");
}

                    Files.write(var2, var4, new OpenOption\[0\]);  
                    return null;  
                } catch (IOException var4x) {  
                    throw new InternalError("I/O exception saving generated file: " + var4x);  
                }  
            }  
        });  
    }

    return var4;  
}

由上面可以看见，核心代码，就是生成了二进制字节码文件Files.write(var2, var4, new OpenOption[0]);

为什么我们看不见呢，那是因为被删除了，可以手动生成这个二进制文件（.class后缀的），也就是上面的那段测试代码的例子。

下面是二进制字节码的文件内容：

import com.example.gof.proxy.BuyCard;
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
import java.lang.reflect.Proxy;
import java.lang.reflect.UndeclaredThrowableException;

public final class $Proxy extends Proxy implements BuyCard {
private static Method m1;
private static Method m2;
private static Method m3;
private static Method m0;

public $Proxy(InvocationHandler var1) throws  {  
    super(var1);  
}

public final boolean equals(Object var1) throws  {  
    try {  
        return (Boolean)super.h.invoke(this, m1, new Object\[\]{var1});  
    } catch (RuntimeException | Error var3) {  
        throw var3;  
    } catch (Throwable var4) {  
        throw new UndeclaredThrowableException(var4);  
    }  
}

public final String toString() throws  {  
    try {  
        return (String)super.h.invoke(this, m2, (Object\[\])null);  
    } catch (RuntimeException | Error var2) {  
        throw var2;  
    } catch (Throwable var3) {  
        throw new UndeclaredThrowableException(var3);  
    }  
}

public final void buycard() throws  {  
    try {  
        super.h.invoke(this, m3, (Object\[\])null);  
    } catch (RuntimeException | Error var2) {  
        throw var2;  
    } catch (Throwable var3) {  
        throw new UndeclaredThrowableException(var3);  
    }  
}

public final int hashCode() throws  {  
    try {  
        return (Integer)super.h.invoke(this, m0, (Object\[\])null);  
    } catch (RuntimeException | Error var2) {  
        throw var2;  
    } catch (Throwable var3) {  
        throw new UndeclaredThrowableException(var3);  
    }  
}

static {  
    try {  
        m1 = Class.forName("java.lang.Object").getMethod("equals", Class.forName("java.lang.Object"));  
        m2 = Class.forName("java.lang.Object").getMethod("toString");  
        m3 = Class.forName("com.example.gof.proxy.BuyCard").getMethod("buycard");  
        m0 = Class.forName("java.lang.Object").getMethod("hashCode");  
    } catch (NoSuchMethodException var2) {  
        throw new NoSuchMethodError(var2.getMessage());  
    } catch (ClassNotFoundException var3) {  
        throw new NoClassDefFoundError(var3.getMessage());  
    }  
}  

}

从上面可以看到，除了自定义的buycard() 方法外，还有toString()、equals()、hashCode() 三个方法。这三个方法是Object 的方法，每个接口、类都会从Object继承这三个方法。当调用buycard()的时候，可以看到调用的是super.h.invoke(xxx) 这样调用的。这里的h，就是我们自定义的，继承了InvocationHandler的类：BuyCardDynamicProxy。

至于invoke方式是怎么调用的，在另外一篇博客https://www.cnblogs.com/drafire/p/9637349.html 继续解析

下面看下cglib的代码解读，依然是先贴出测试代码

public class BuyCardCglibProxy implements MethodInterceptor {
private Object target;

public Object getInstance(final Object target) {  
    this.target = target;  
    Enhancer enhancer=new Enhancer();  
    enhancer.setSuperclass(target.getClass());  
    enhancer.setCallback(this);  
    return enhancer.create();  
}

@Override  
public Object intercept(Object o, Method method, Object\[\] objects, MethodProxy methodProxy) throws Throwable {  
    System.out.println("cglib动态代理前");  
    //这里使用的是methodProxy.invokeSuper，而不是method.invoke  
    //代理类调用父类的方法  
    Object res= methodProxy.invokeSuper(o,objects);  
    System.out.println("cglib动态代理后");  
    return res;  
}  

}

package com.example.gof.proxy;

import com.example.gof.proxy.impl.BuyCardImpl;

public class TestBuyCardCglibProxy {

BuyCard buyCard=new BuyCardImpl();
BuyCardCglibProxy proxy=new BuyCardCglibProxy();
BuyCardImpl impl= (BuyCardImpl)proxy.getInstance(buyCard);
impl.buycard();
}
}

关键代码在：enhancer.create() 这个方法，跟踪进去，代码如下：
