Spring3.0学习笔记

Spring3.0不但需要Spring的标准jar包,还有些与2.5增加了的一些jar包:aspectjweaver.jar,aspectjrt.jar,log4j-1.2.16.jar,commons-logging-1.1.1.jar,aspectj-1.6.10.jar,asm.jar,cglib-2.1.3.jar,aopalliance.jar,aopalliance-alpha1.jar

package com.fire.dao;

public interface UserDao {


}

package com.fire.dao.impl;

import com.fire.dao.UserDao;

public class UserDaoImpl implements UserDao{

	public UserDaoImpl() {
		System.out.println("***********Create  ****UserDaoImpl()*************");
	}

}

package com.fire.service;

import com.fire.dao.UserDao;


public class UserDaoService {
	
	public UserDaoService() {
		System.out.println("Create ********UserDaoService()**********");
	}

	private UserDao userDAO;

	public UserDao getUserDAO() {
		return userDAO;
	}

	public void setUserDAO(UserDao userDAO) {
		this.userDAO = userDAO;
	}

	



}
