Reading minds:

1  Packageimple;2 3 ImportInter.

Thoughts =thoughts; - System.out.println (thoughts); -SYSTEM.OUT.PRINTLN ("Rear"); the     } -  -      PublicString getthoughts () { -         returnthoughts; +     } -  +}

Volunteers:

1  Package Inter; 2 3  Public Interface Thinker {4     void thinkofsomething (String thoughts); 5 }

1  Packageimple;2 3 ImportInter. Thinker;4 5  Public classVolunteerImplementsthinker{6 7     PrivateString Thoughts;8     9      Public voidthinkofsomething (String thoughts) {Ten          This. Thoughts =thoughts; One     } A  -      PublicString getthoughts () { -         returnthoughts; the     } -}

Test code:

1     @Test 2      Public void test7 () {3         Magician Magician = (Magician) ctx.getbean ("Magician"); 4         Magician.interceptthoughts ("SSSs"); 5     }

Operation Result:
