复制代码到src 然后直接运行，大家都喜欢这样。哎

package faicm.model;

public class Person {

	private int age;
	private String name;

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

package faicm.aop;

import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect//意思是这个类为切面类
public class AopPerson {

	@Pointcut("execution(* faicm.server.*.find*(..))")//切点，符合切点表达式的连接点，也就是真正被切入的地方；
	public void checkUser() {
		System.out.println("point___aop___checkUser");
	}

	@Pointcut("execution(* faicm.server.*.add*(..))")
	public void checkAdd() {
		System.out.println("point___aop___checkAdd");
	}

	@Before("checkUser()")
	public void beforeCheck() {
		System.out.println("aop___beforeCheck");
	}

	@After("checkUser()")
	public void afterCheck() {
		System.out.println("aop___afterCheck");
	}

	@Before("checkAdd()")
	public void beforeAdd() {
		System.out.println("aop___beforeAdd");
	}

	@After("checkAdd()")
	public void afterAdd() {
		System.out.println("aop___afterAdd");
	}
}

package faicm.server;

public interface PersonDo {

	public void findUser(String username);

	public void addUser(String username);

	public void findAll();
}

package faicm.server;

public class PersonDoImpl implements PersonDo {

	public void addUser(String username) {
		System.out.println("add    " + username);
	}

	public void findAll() {
		System.out.println("---- findall-----");
	}

	public void findUser(String username) {
		System.out.println("---- -findPerson:" + username + "------");

	}

}

完了，复制即可运行。。。。。。
