Spring中的拦截器与动态代理的几大模式

分手后的思念是犯贱 2021-09-18 14:08 170阅读 0赞

### 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
 *  Cglib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。

1.  `public interface People {`
2.  `   /**`
3.  `    * 交谈`
4.  `    */`
5.  `   void speak();`
6.  `}`

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。

1.  `public class HuangNiu  implements InvocationHandler {`
2.   
3.  `   private People people;`
4.  `   /**`
5.  `    * 获取被代理对象信息`
6.  `    */`
7.  `   public Object getInstance(People people){`
8.  `       this.people = people;`
9.  `       Class clazz = people.getClass();`
10. `       System.out.println("没生成代理之前的class对象:"+clazz );`
11. `       return Proxy.newProxyInstance(clazz.getClassLoader(), clazz.getInterfaces(), this);`
12. `   }`
13.  
14. `   @Override`
15. `   public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {`
16. `       System.out.println("代理中...");`
17. `       method.invoke(people);`
18. `       System.out.println("代理处理完毕,OK,请查收");`
19. `       return null;`
20. `   }`
21. `}`

在实例化HuangNiu这个对象的时候，我们调用了Proxy的newProxyInstance方法:

1.  `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:

1.  `public static Object newProxyInstance(ClassLoader loader,`
2.  `                                         Class<?>[] interfaces,`
3.  `                                         InvocationHandler h){`
4.   
5.  `       final Class<?>[] intfs = interfaces.clone();`
6.   
7.  `       //Look up or generate the designated proxy class.`
8.   
9.  `       Class<?> cl = getProxyClass0(loader, intfs);`
10.  
11. `       //获取代理类的构造函数对象`
12. `       //参数constructorParames为常量值：private static final Class<?>[] constructorParams = { InvocationHandler.class };`
13. `       final Constructor<?> cons = cl.getConstructor(constructorParames);`
14. `       final InvocationHandler ih = h;`
15. `       //根据代理类的构造函数对象来创建代理类对象`
16. `       return newInstance(cons, ih);`
17. `}`

getProxyClass0方法源码:

1.  `   private static Class<?> getProxyClass0(ClassLoader loader,`
2.  `                                          Class<?>... interfaces) {`
3.  `       if (interfaces.length > 65535) {`
4.  `           throw new IllegalArgumentException("interface limit exceeded");`
5.  `       }`
6.   
7.  `       // If the proxy class defined by the given loader implementing`
8.  `       // the given interfaces exists, this will simply return the cached copy;`
9.  `       // otherwise, it will create the proxy class via the ProxyClassFactory`
10. `       return proxyClassCache.get(loader, interfaces);`
11. `   }`

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。

1.  `public class Me implements People {`
2.   
3.  `   private String name;`
4.  `   private String type;`
5.   
6.  `   Me(String name, String type){`
7.  `       this.name = name;`
8.  `       this.type = type;`
9.  `   }`
10. `   @Override`
11. `   public void speak() {`
12. `       System.out.println("我叫"+name+", 我要一张"+type);`
13. `   }`
14. `}`

1.4 Main.java

1.  `public class Main {`
2.  `   public static void main(String[] args) {`
3.  `       People instance = (People)new HuangNiu().getInstance(new Me("Fantj", "JAY演唱会门票"));`
4.  `       instance.speak();`
5.  `       System.out.println("生成代理对象后对象变成:"+instance.getClass());`
6.  `   }`
7.  `}`

执行结果:

1.  `没生成代理之前的class对象:class com.fantj.proxy.jdk.Me`
2.  `代理中...`
3.  `我叫Fantj, 我要一张JAY演唱会门票`
4.  `代理处理完毕,OK,请查收`
5.  `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):

1.  `/**`
2.  `* 生成代码`
3.  `*/`
4.  `try {`
5.  `   byte[] $Proxy0s = ProxyGenerator.generateProxyClass("$Proxy0", new Class[]{instance.getClass()});`
6.  `   String path = Main.class.getResource("").toString();`
7.  `//            System.out.println("get the path"+path);`
8.  `   FileOutputStream fileOutputStream = new FileOutputStream("$Proxy0.class");`
9.  `   fileOutputStream.write($Proxy0s);`
10. `   fileOutputStream.close();`
11. `} catch (IOException e) {`
12. `   e.printStackTrace();`
13. `}`

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。

175. `           m5 = Class.forName("com.sun.proxy.$Proxy0").getMethod("getInvocationHandler", Class.forName("java.lang.Object"));`
176. `           m2 = Class.forName("java.lang.Object").getMethod("toString");`
177. `           m4 = Class.forName("com.sun.proxy.$Proxy0").getMethod("getProxyClass", Class.forName("java.lang.ClassLoader"), Class.forName("[Ljava.lang.Class;"));`
178. `           m11 = Class.forName("com.sun.proxy.$Proxy0").getMethod("getClass");`
179. `           m13 = Class.forName("com.sun.proxy.$Proxy0").getMethod("notifyAll");`

183. `           m6 = Class.forName("com.sun.proxy.$Proxy0").getMethod("newProxyInstance", Class.forName("java.lang.ClassLoader"), Class.forName("[Ljava.lang.Class;"), Class.forName("java.lang.reflect.InvocationHandler"));`
184. `           m9 = Class.forName("com.sun.proxy.$Proxy0").getMethod("wait", Long.TYPE);`
185. `           m3 = Class.forName("com.sun.proxy.$Proxy0").getMethod("speak");`
186. `           m7 = Class.forName("com.sun.proxy.$Proxy0").getMethod("isProxyClass", Class.forName("java.lang.Class"));`
187. `           m8 = Class.forName("com.sun.proxy.$Proxy0").getMethod("wait", Long.TYPE, Integer.TYPE);`
188. `       } catch (NoSuchMethodException var2) {`
189. `           throw new NoSuchMethodError(var2.getMessage());`
190. `       } catch (ClassNotFoundException var3) {`
191. `           throw new NoClassDefFoundError(var3.getMessage());`
192. `       }`
193. `   }`
194. `}`

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:

1.  `People instance = (People)new HuangNiu().getInstance(new Me("Fantj", "JAY演唱会门票"));`
2.  `instance.speak();`
3.   
4.  `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:`
5.   
6.  `public final void speak() throws  {`
7.  `   try {`
8.  `       super.h.invoke(this, m3, (Object[])null);`
9.  `   } catch (RuntimeException | Error var2) {`
10. `       throw var2;`
11. `   } catch (Throwable var3) {`
12. `       throw new UndeclaredThrowableException(var3);`
13. `   }`
14. `}`

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:

1.  `private static final class ProxyClassFactory`
2.  `   implements BiFunction<ClassLoader, Class<?>[], Class<?>>`
3.  `{`
4.  `   // prefix for all proxy class names`
5.  `   // 所有代理类的前缀`
6.  `   private static final String proxyClassNamePrefix = "$Proxy";`
7.   
8.  `   // next number to use for generation of unique proxy class names`
9.  `   // 用java8新增的原子性AtomicLong类来做线程安全计数`
10. `   private static final AtomicLong nextUniqueNumber = new AtomicLong();`
11.  
12. `       /*`
13. `        * Choose a name for the proxy class to generate.`
14. `        */`
15. `     // 拼接代理类 类名`
16. `       long num = nextUniqueNumber.getAndIncrement();`
17. `       String proxyName = proxyPkg + proxyClassNamePrefix + num;`
18. `       ...`
19. `       ...`
20. `}`

### 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:

1.  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。
2.  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

1.  `public class Me {`
2.   
3.  `   private String name = "FantJ";`
4.  `   private String type = "JAY演唱会门票";`
5.   
6.  `   Me() {`
7.   
8.  `   }`
9.   
10. `   Me(String name, String type){`
11. `       this.name = name;`
12. `       this.type = type;`
13. `   }`
14. `   public void speak() {`
15. `       System.out.println("我叫"+name+", 我要一张"+type);`
16. `   }`
17.  
18. `   public String getName() {`
19. `       return name;`
20. `   }`
21.  
22. `   public void setName(String name) {`
23. `       this.name = name;`
24. `   }`
25.  
26. `   public String getType() {`
27. `       return type;`
28. `   }`
29.  
30. `   public void setType(String type) {`
31. `       this.type = type;`
32. `   }`
33. `}`

HuangNiu.java

该类要实现cglib包下的MethodInterceptor接口，从而实现对intercept的调用。

1.  `public class HuangNiu  implements MethodInterceptor {`
2.   
3.  `   /**`
4.  `    * 获取被代理对象信息`
5.  `    *`
6.  `    */`
7.  `   public Object getInstance(Object object){`
8.  `       Enhancer enhancer = new Enhancer();`
9.  `       enhancer.setSuperclass(object.getClass());`
10. `       System.out.println("生成代理对象前对象是:"+object.getClass());`
11. `       enhancer.setCallback(this);`
12. `       return enhancer.create();`
13. `   }`
14.  
15. `   @Override`
16. `   public Object intercept(Object o, Method method, Object[] objects, MethodProxy methodProxy) throws Throwable {`
17. `       System.out.println("代理中...");`
18. `       methodProxy.invokeSuper(o, objects);`
19. `//        methodProxy.invoke(o, objects);`
20. `       System.out.println("代理处理完毕,OK,请查收");`
21. `       return null;`
22. `   }`
23. `}`

Main.java

1.  `public class Main {`
2.  `   public static void main(String[] args) {`
3.  `       Me instance = (Me)new HuangNiu().getInstance(new Me("Fantj", "JAY演唱会门票"));`
4.  `//        Me instance = (Me)new HuangNiu().getInstance(new Me());`
5.  `       instance.speak();`
6.  `       System.out.println("生成代理对象后对象变成:"+instance.getClass());`
7.   
8.  `       /**`
9.  `        * 生成代码`

控制台结果:

1.  `生成代理对象前对象是:class com.fantj.proxy.cglib.Me`
2.  `代理中...`
3.  `我叫FantJ, 我要一张JAY演唱会门票`
4.  `代理处理完毕,OK,请查收`
5.  `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。
