GetBooleanAction实际上是调用Boolean.getBoolean(propName)来获得的，而Boolean.getBoolean(propName)调用了System.getProperty(name) ，所以我们可以设置
sun.misc.ProxyGenerator.saveGeneratedFiles这个系统属性为true来把生成的class保存到本地文件来查看。
这里要注意，当把这个属性设置为true时，生成的class文件及其所在的路径都需要提前创建，否则会抛出FileNotFoundException异常。如：
Exception in thread "main" java.lang.InternalError: I/O exception saving generated file: java.io.FileNotFoundException: com/sun/proxy/$Proxy0.class (No such file or directory)at sun.misc.ProxyGenerator$1.run(ProxyGenerator.java:336)at sun.misc.ProxyGenerator$1.run(ProxyGenerator.java:327)at java.security.AccessController.doPrivileged(Native Method)at sun.misc.ProxyGenerator.generateProxyClass(ProxyGenerator.java:326)at java.lang.reflect.Proxy$ProxyClassFactory.apply(Proxy.java:672)at java.lang.reflect.Proxy$ProxyClassFactory.apply(Proxy.java:592)at java.lang.reflect.WeakCache$Factory.get(WeakCache.java:244)at java.lang.reflect.WeakCache.get(WeakCache.java:141)at java.lang.reflect.Proxy.getProxyClass0(Proxy.java:455)at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:738)at com.mikan.proxy.ProxyTest.main(ProxyTest.java:15)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)at java.lang.reflect.Method.invoke(Method.java:606)at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140)

即我们要在运行当前main方法的路径下创建com/sun/proxy目录，并创建一个$Proxy0.class文件，才能够正常运行并保存class文件内容。
反编译$Proxy0.class文件，如下所示：
package com.sun.proxy;import com.mikan.proxy.HelloWorld;import java.lang.reflect.InvocationHandler;import java.lang.reflect.Method;import java.lang.reflect.Proxy;import java.lang.reflect.UndeclaredThrowableException;public final class $Proxy0 extends Proxy implements HelloWorld { private static Method m1; private static Method m3; private static Method m0; private static Method m2; public $Proxy0(InvocationHandler paramInvocationHandler) { super(paramInvocationHandler); } public final boolean equals(Object paramObject) { try { return ((Boolean)this.h.invoke(this, m1, new Object[] { paramObject })).booleanValue(); } catch (Error|RuntimeException localError) { throw localError; } catch (Throwable localThrowable) { throw new UndeclaredThrowableException(localThrowable); } } public final void sayHello(String paramString) { try { this.h.invoke(this, m3, new Object[] { paramString }); return; } catch (Error|RuntimeException localError) { throw localError; } catch (Throwable localThrowable) { throw new UndeclaredThrowableException(localThrowable); } } public final int hashCode() { try { return ((Integer)this.h.invoke(this, m0, null)).intValue(); } catch (Error|RuntimeException localError) { throw localError; } catch (Throwable localThrowable) { throw new UndeclaredThrowableException(localThrowable); } } public final String toString() { try { return (String)this.h.invoke(this, m2, null); } catch (Error|RuntimeException localError) { throw localError; } catch (Throwable localThrowable) { throw new UndeclaredThrowableException(localThrowable); } } static { try { m1 = Class.forName("java.lang.Object").getMethod("equals", new Class[] { Class.forName("java.lang.Object") }); m3 = Class.forName("com.mikan.proxy.HelloWorld").getMethod("sayHello", new Class[] { Class.forName("java.lang.String") }); m0 = Class.forName("java.lang.Object").getMethod("hashCode", new Class[0]); m2 = Class.forName("java.lang.Object").getMethod("toString", new Class[0]); return; } catch (NoSuchMethodException localNoSuchMethodException) { throw new NoSuchMethodError(localNoSuchMethodException.getMessage()); } catch (ClassNotFoundException localClassNotFoundException) { throw new NoClassDefFoundError(localClassNotFoundException.getMessage()); } }}
