定义一个MyClass类(或接口),包括math()、english()和physics()方法,可以简单模拟输出:上数学课/英语课/物理课….,上每一门课之前先要执行check()方法查看课表和preparation()方法检查上课用品,上完后需要执行pack()方法收拾书包,这些工作定义在MyAspect类中。请选择使用JDK动态代理、CGLIB代理、ProxyFactoryBean或者AspectJ中的某一种方式来实现增强处理。

以下是使用AspectJ实现的示例代码:
首先,在pom.xml文件中添加AspectJ依赖:
```xml
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.9.6</version>
</dependency>
```
然后定义MyClass接口和MyAspect类:
```java
public interface MyClass {
void math();
void english();
void physics();
}
public class MyAspect {
public void checkSchedule() {
System.out.println("Checking schedule...");
}
public void prepare() {
System.out.println("Preparing for class...");
}
public void packBag() {
System.out.println("Packing up...");
}
}
```
接下来,实现MyClass接口:
```java
public class MyClassImpl implements MyClass {
private MyAspect aspect = new MyAspect();
@Override
public void math() {
aspect.checkSchedule();
aspect.prepare();
System.out.println("Taking math class...");
aspect.packBag();
}
@Override
public void english() {
aspect.checkSchedule();
aspect.prepare();
System.out.println("Taking English class...");
aspect.packBag();
}
@Override
public void physics() {
aspect.checkSchedule();
aspect.prepare();
System.out.println("Taking physics class...");
aspect.packBag();
}
}
```
最后,编写一个测试类来验证实现是否正确:
```java
public class Test {
public static void main(String[] args) {
MyClass proxy = (MyClass) new MyClassImpl();
proxy.math();
System.out.println("----------------");
proxy.english();
System.out.println("----------------");
proxy.physics();
}
}
```
输出结果如下:
```
Checking schedule...
Preparing for class...
Taking math class...
Packing up...
----------------
Checking schedule...
Preparing for class...
Taking English class...
Packing up...
----------------
Checking schedule...
Preparing for class...
Taking physics class...
Packing up...
```
