spring2 aop 例子

记录下AOP编程常用情况，调整格式，方便阅读

首先建立个被切入的类

package sinlff.aop;

/**
* @author sinlff
*人实体
*/
public class Person{
/**
*年龄
*/
private int age;

/**
*姓名
*/
private Stringname;

public void birthday(Stringname) throws Exception{
throw new Exception( " birthday'sExceptionMessage...... " );
}

/** 返回年龄
* @return theage
*/
public int getAge(){
return age;
}

/** 设置年龄
* @param agetheagetoset
*/
public void setAge( int age){
this .age = age;
}

/** 返回姓名
* @return thename
*/
public StringgetName(){
return name;
}
/** 设置姓名
* @param stringthenametoset
*/
public void setName(Stringstring){
this .name = string;
}

}

要切入Person类的birthday()方法的类

package sinlff.aop;

public class BirthdayExecute{

/** 当Person类里的birthday执行抛出异常,则执行的函数
* @param Exceptionexception类的对象
*/
public void throwExceptionBirthday(Exceptionexception) throws Exception{
System.out.println(exception.getMessage() + " throwExceptionBirthdayexecute...... " );
}

/** 当Person类里的birthday执行之前,则执行的函数
* @param namebirthday函数的字符串参数
*/
public void beforeBirthday(Stringname){
System.out.println(name + " beforeBirthdayexecute...... " );
}

/** 当Person类里的birthday执行之后,则执行的函数
* @param personPerson类的对象
*/
public void afterBirthday(Personperson){
System.out.println(person.getName() + " afterBirthdayexecute...... " );
}
}

测试

package sinlff.test;

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

import sinlff.aop.Person;


import junit.framework.TestCase;

public class TestAOP extends TestCase{

private Personperson;

public void setUp(){
ApplicationContextapplicationContext = new ClassPathXmlApplicationContext( " applicationContext.xml " );
person = (Person)applicationContext.getBean( " person " );
}

public void testSendCardAOP() throws Exception{
person.setName( " sinlff " );
person.setAge( 22 );
person.birthday( " newname " );
}
}

暂时只给出完整例子，因为我查到的资料都很零散，而且格式排版都很难看，内容给的不完整，导致学习障碍
