读心术：

1 package inter;
2
3 public interface MindReader {
4
5     void interceptThoughts(String thoughts);
6
7     String getThoughts();
8
9 }

 1 package imple;
 2
 3 import inter.MindReader;
 4
 5 public class Magician implements MindReader{
 6
 7     private String thoughts;
 8
 9     public void interceptThoughts(String thoughts) {
10
11         System.out.println("前置Intercepting volunter‘s thoughts");
12         this.thoughts = thoughts;
13         System.out.println(thoughts);
14         System.out.println("后置");
15     }
16
17     public String getThoughts() {
18         return thoughts;
19     }
20
21 }

志愿者：

1 package inter;
2
3 public interface Thinker {
4     void thinkOfSomething(String thoughts);
5 }

 1 package imple;
 2
 3 import inter.Thinker;
 4
 5 public class Volunteer implements Thinker{
 6
 7     private String thoughts;
 8
 9     public void thinkOfSomething(String thoughts) {
10         this.thoughts = thoughts;
11     }
12
13     public String getThoughts(){
14         return thoughts;
15     }
16 }

测试代码：

1     @Test
2     public void test7(){
3         Magician magician = (Magician) ctx.getBean("magician");
4         magician.interceptThoughts("ssss");
5     }

运行结果：

前置Intercepting volunter‘s thoughts
ssss
后置
