spring2 aop 例子

記錄下AOP編程常用情況，調整格式，方便閱讀

首先建立個被切入的類

package sinlff.aop;

/**
 * @author sinlff
 * 人實體
 */
public class Person {
    /**
     * 年齡
     */
    private int age;
    
    /**
     * 姓名
     */
    private String name;

    public void birthday(String name) throws Exception {
        throw new Exception("birthday's Exception Message......");
    }
    
    /**返回年齡
     * @return the age
     */
    public int getAge() {
        return age;
    }

    /**設置年齡
     * @param age the age to set
     */
    public void setAge(int age) {
        this.age = age;
    }

    /**返回姓名
     * @return the name
     */
    public String getName() {
        return name;
    }
    /**設置姓名
     * @param string the name to set
     */
    public void setName(String string) {
        this.name = string;
    }

}

 

要切入Person類的 birthday()方法的類

 

package sinlff.aop;

public class BirthdayExecute {

    /**當Person類裏的birthday執行拋出異常,則執行的函數
     * @param Exception exception類的對象
     */
    public void throwExceptionBirthday(Exception exception) throws Exception{  
        System.out.println( exception.getMessage() + "  throwExceptionBirthday execute......");
    }
    
    /**當Person類裏的birthday執行之前,則執行的函數
     * @param name birthday函數的字符串參數
     */
     public void beforeBirthday(String name) { 
         System.out.println(name+" beforeBirthday execute......");
     }
     
    /**當Person類裏的birthday執行之後,則執行的函數
     * @param person Person類的對象
     */
    public void afterBirthday(Person person) {   
        System.out.println(person.getName() +"  afterBirthday execute......");
    }
}

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import sinlff.aop.Person; 
 

import junit.framework.TestCase;
