AspectJ代码修改
一：
1 public aspect MyAspect { 2 pointcut move(): 3 call(void Point.setX(int)); 4 before(): move() { 5 System.out.println("before call Point.setX"); 6 } 7 }
AOP后，修改了.class文件，修改后为
1 public void setXY(int x, int y) 2 { 3 System.out.println("Point.setXY is calling..."); 4 MyAspect.aspectOf().ajc$before$aspects_MyAspect$1$c0539092(); setX(x); 5 setY(y); 6 }
二：
1 public aspect MyAspect { 2 pointcut move(): 3 call(void Point.setX(int)); 4 after(): move() { 5 System.out.println("before call Point.setX"); 6 } 7 }
修改后：
1 public void setXY(int x, int y) 2 { 3 System.out.println("Point.setXY is calling..."); 4 try { setX(x); } catch (Throwable localThrowable) { MyAspect.aspectOf().ajc$after$aspects_MyAspect$1$c0539092(); throw localThrowable; } MyAspect.aspectOf().ajc$after$aspects_MyAspect$1$c0539092(); 5 setY(y); 6 }
三：
1 public aspect MyAspect { 2 pointcut move(): 3 call(void Point.setX(int)); 4 after() returning: move() { 5 System.out.println("before call Point.setX"); 6 } 7 }

1 public void setXY(int x, int y) 2 { 3 System.out.println("Point.setXY is calling..."); 4 setX(x); MyAspect.aspectOf().ajc$afterReturning$aspects_MyAspect$1$c0539092(); 5 setY(y); 6 }
四：
1 public aspect MyAspect { 2 pointcut move(): 3 call(void Point.setX(int)); 4 after() throwing: move() { 5 System.out.println("before call Point.setX"); 6 } 7 }

1 public void setXY(int x, int y) 2 { 3 System.out.println("Point.setXY is calling..."); 4 try { setX(x); } catch (Throwable localThrowable) { MyAspect.aspectOf().ajc$afterThrowing$aspects_MyAspect$1$c0539092(); throw localThrowable; } 5 setY(y); 6 }
五：
1 public aspect MyAspect { 2 pointcut move(): 3 call(* *.setX(int)); 4 pointcut canMove(): 5 within(javaexercise.FigureElement); 6 7 Object around(): move(){ 8 System.out.println("around call Point.setX" 9 ); 10 return proceed(); 11 } 12 }

//ERROR//是什么意思，难道是没有反编译成功？
十二：
1 before():get(* javaexercise.Point.*){ 2 System.out.println("before get"); 3 }
修改为：
1 public int getX() { 2 System.out.println("Point.getX is called..."); 3 MyAspect.aspectOf().ajc$before$aspects_MyAspect$1$54b470a9(); return this.x; 4 }
十三：
1 before():set(* javaexercise.Point.*){ 2 System.out.println("before set"); 3 }
修改后：
1 public void setX(int x) { 2 System.out.println("Point.setX is calling..."); 3 MyAspect.aspectOf().ajc$before$aspects_MyAspect$1$48139b5(); this.x = x; 4 }
