彻底搞懂动态代理动态代理
什么是代理模式?
如果用专业术语来解：为其他对象提供一种代理以控制对这个对象的访问。如果投影在生活中，它可以理解成中介 黄牛 经纪人等…
解决的问题:
在直接访问对象时带来的问题，比如说：要访问的对象在远程的机器上。在面向对象系统中，有些对象由于某些原因（比如对象创建开销很大，或者某些操作需要安全控制，或者需要进程外的访问），直接访问会给使用者或者系统结构带来很多麻烦，我们可以在访问此对象时加上一个对此对象的访问层。说白了就是在你代码前面插一段后面插一段。
Java动态代理实现方式:
-
JDK 自带的动态代理
1. JDK 自带的动态代理
我以黄牛为例，黄牛刚开始了解该人需求，该人将信息(JAY演唱会门票)给予黄牛，黄牛给票。黄牛就是该买票人的代理。
1.1 People.java
注意这必须是一个接口，原因往下看。
public interface People {
/**
* 交谈
*/
void speak();
}
这个接口很简单，就是一个讲话的功能，但是它为什么必须是一个接口呢。因为在HuangNiu这个类中，Proxy.newProxyInstance 这个方法的实现需要接口,这一点我在HuangNiu类下解释的很清楚，往下看。
1.2 HuangNiu.java
黄牛代理类，获取到People信息后调用Proxy来生成一个新的代理类,它必须实现InvocationHandler接口,这个接口使得它可以通过invoke方法实现对真实角色(People)的代理访问。
public class HuangNiu implements InvocationHandler {
private People people;
/**
* 获取被代理对象信息
*/
public Object getInstance(People people){
this.people = people;
Class clazz = people.getClass();
System.out.println("没生成代理之前的class对象:"+clazz );
return Proxy.newProxyInstance(clazz.getClassLoader(), clazz.getInterfaces(), this);
}
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
System.out.println("代理中...");
method.invoke(people);
System.out.println("代理处理完毕,OK,请查收");
return null;
}
}
在实例化HuangNiu这个对象的时候，我们调用了Proxy的newProxyInstance方法:
return Proxy.newProxyInstance(clazz.getClassLoader(), clazz.getInterfaces(), this);
其中clazz是People的class对象。再来看看newProxyInstance的源码实现:
public static Object newProxyInstance(ClassLoader loader,
Class<?>[] interfaces,
InvocationHandler h){
final Class<?>[] intfs = interfaces.clone();
//Look up or generate the designated proxy class.
Class<?> cl = getProxyClass0(loader, intfs);
//获取代理类的构造函数对象
//参数constructorParames为常量值：private static final Class<?>[] constructorParams = { InvocationHandler.class };
final Constructor<?> cons = cl.getConstructor(constructorParames);
final InvocationHandler ih = h;
//根据代理类的构造函数对象来创建代理类对象
return newInstance(cons, ih);
}
getProxyClass0方法源码:
private static Class<?> getProxyClass0(ClassLoader loader,
Class<?>... interfaces) {
if (interfaces.length > 65535) {
throw new IllegalArgumentException("interface limit exceeded");
}
// If the proxy class defined by the given loader implementing
// the given interfaces exists, this will simply return the cached copy;
// otherwise, it will create the proxy class via the ProxyClassFactory
return proxyClassCache.get(loader, interfaces);
}
如果缓存中有该代理类，则取缓存，如果没有，则通过ProxyClassFactory来创建代理类。如果对如何生成代理类感兴趣则追踪下去即可。
我只取了核心代码和注释，可以看到JDK的动态代理实现是依据接口来重新生成一个新的代理类，
什么是新的代理类?
通俗点说就是综合和前后代理逻辑并重新生成一份.class文件来实现动态代理的类，下面也会具体说。
1.3 Me.java
被代理对象，实现了People接口,给代理提供需要的信息来实现被代理。
public class Me implements People {
private String name;
private String type;
Me(String name, String type){
this.name = name;
this.type = type;
}
@Override
public void speak() {
System.out.println("我叫"+name+", 我要一张"+type);
}
}
1.4 Main.java
public class Main {
public static void main(String[] args) {
People instance = (People)new HuangNiu().getInstance(new Me("Fantj", "JAY演唱会门票"));
instance.speak();
System.out.println("生成代理对象后对象变成:"+instance.getClass());
}
}
执行结果:
没生成代理之前的class对象:class com.fantj.proxy.jdk.Me
代理中...
我叫Fantj, 我要一张JAY演唱会门票
代理处理完毕,OK,请查收
生成代理对象后对象变成:class com.sun.proxy.$Proxy0
为了证明事实上真的有代理类的产生，我在代理完成前和代理完成后分别打印出它的类信息，可以看出是不同的，可以猜想到代理中是有代理类产生的，这个代理类就是$Proxy0。
那既然知道了这个类的信息，我们就可以逆向生成这个.class文件来看看(在main方法后追加):
/**
* 生成代码
*/
try {
byte[] $Proxy0s = ProxyGenerator.generateProxyClass("$Proxy0", new Class[]{instance.getClass()});
String path = Main.class.getResource("").toString();
// System.out.println("get the path"+path);
FileOutputStream fileOutputStream = new FileOutputStream("$Proxy0.class");
fileOutputStream.write($Proxy0s);
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
它默认生成在项目根目录下: 我使用的IDEA工具会自动反编译.class文件为java代码，直接打开即刻看到源码，如果用别的工具的可以下载反编译工具来进行反编译。

} catch (ClassNotFoundException var3) {
throw new NoClassDefFoundError(var3.getMessage());

}
}
里面大多是Object中的方法，还有我们定义的speak()方法，然后就是静态代码块(对变量进行初始化)。
当我们在Main中:
People instance = (People)new HuangNiu().getInstance(new Me("Fantj", "JAY演唱会门票"));
instance.speak();
调用instance.speak();时，事实上就调用了$Proxy0中的speak()方法，然后在该方法中再调用父类Proxy的invoke方法:
public final void speak() throws {
try {
super.h.invoke(this, m3, (Object[])null);
} catch (RuntimeException | Error var2) {
throw var2;
} catch (Throwable var3) {
throw new UndeclaredThrowableException(var3);
}
}
其中，super.h.invoke的调用的是父类Proxy中的InvocationHandler.invoke()方法.
最后
你一定也很好奇它的名字为什么是$Proxy0,也一定很好奇第二个代理类的命名。
ProxyClassFactory类中的代码中有体现:
private static final class ProxyClassFactory
implements BiFunction<ClassLoader, Class<?>[], Class<?>>
{
// prefix for all proxy class names
// 所有代理类的前缀
private static final String proxyClassNamePrefix = "$Proxy";
// next number to use for generation of unique proxy class names
// 用java8新增的原子性AtomicLong类来做线程安全计数
private static final AtomicLong nextUniqueNumber = new AtomicLong();
/*
* Choose a name for the proxy class to generate.
*/
// 拼接代理类 类名
long num = nextUniqueNumber.getAndIncrement();
String proxyName = proxyPkg + proxyClassNamePrefix + num;
...
...
}
2. Cglib实现动态代理
Cglib动态代理的实现原理和jdk基本一样，但是也有不同点。
不同点:
jdk动态代理生成的代理类是继承自Proxy，实现你的被代理类所实现的接口，要求必须有接口。
cglib动态代理生成的代理类是被代理者的子类，并且会重写父类的所有方法，要求该父类必须有空的构造方法,否则会报错:Superclass has no null constructors but no arguments were given,还有，private和final修饰的方法不会被子类重写。
相同点:
都是生成了新的代理类(字节码重组)。
Me.java
public class Me {
private String name = "FantJ";
private String type = "JAY演唱会门票";
Me() {
}
Me(String name, String type){
this.name = name;
this.type = type;
}
public void speak() {
System.out.println("我叫"+name+", 我要一张"+type);
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
}
HuangNiu.java
该类要实现cglib包下的MethodInterceptor接口，从而实现对intercept的调用。
public class HuangNiu implements MethodInterceptor {
/**
* 获取被代理对象信息
*
*/
public Object getInstance(Object object){
Enhancer enhancer = new Enhancer();
enhancer.setSuperclass(object.getClass());
System.out.println("生成代理对象前对象是:"+object.getClass());
enhancer.setCallback(this);
return enhancer.create();
}
@Override
public Object intercept(Object o, Method method, Object[] objects, MethodProxy methodProxy) throws Throwable {
System.out.println("代理中...");
methodProxy.invokeSuper(o, objects);
// methodProxy.invoke(o, objects);
System.out.println("代理处理完毕,OK,请查收");
return null;
}
}
Main.java
public class Main {
public static void main(String[] args) {
Me instance = (Me)new HuangNiu().getInstance(new Me("Fantj", "JAY演唱会门票"));
// Me instance = (Me)new HuangNiu().getInstance(new Me());
instance.speak();
System.out.println("生成代理对象后对象变成:"+instance.getClass());
/**
* 生成代码
*/
try {
byte[] $Proxy0s = ProxyGenerator.generateProxyClass("Me$$EnhancerByCGLIB$$5d2d06a1", new Class[]{instance.getClass()});
String path = com.fantj.proxy.jdk.Main.class.getResource("").toString();
// System.out.println("get the path"+path);
FileOutputStream fileOutputStream = new FileOutputStream("Me$$EnhancerByCGLIB$$5d2d06a1.class");
fileOutputStream.write($Proxy0s);
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
控制台结果:
生成代理对象前对象是:class com.fantj.proxy.cglib.Me
代理中...
我叫FantJ, 我要一张JAY演唱会门票
代理处理完毕,OK,请查收
生成代理对象后对象变成:class com.fantj.proxy.cglib.Me$$EnhancerByCGLIB$$5d2d06a1
同上，我们也把它生成的代理类反编译得到Me$$EnhancerByCGLIB$$5d2d06a1.java,原理和上面JDK代理类似，举一反三，这里不做介绍。
