Spring2.5 注解的魔力

转此文 特别感谢remote_roamer的专栏
remote_roamer写的很详细，不过我自己配置还是有部分区别，贴出我自己的配置。

贴出一个Dommain

package model.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "userinfo", catalog = "test")
public class Userinfo implements java.io.Serializable {

	// Fields

	private String id;
	private String username;
	private String password;
	private String email;

	// Constructors

	/** default constructor */
	public Userinfo() {
	}

	/** full constructor */
	public Userinfo(String id, String username, String password, String email) {
		this.id = id;
		this.username = username;
		this.password = password;
		this.email = email;
	}

	// Property accessors
	@Id
	@Column(name = "id", unique = true, nullable = false, length = 50)
	public String getId() {
		return this.id;
	}

	public void setId(String id) {
		this.id = id;
	}

	@Column(name = "username", nullable = false, length = 40)
	public String getUsername() {
		return this.username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	@Column(name = "password", nullable = false, length = 20)
	public String getPassword() {
		return this.password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	@Column(name = "email", nullable = false, length = 60)
	public String getEmail() {
		return this.email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

}

贴出个Service

package model.service.impl;

import model.dao.UserInfoDao;
import model.entity.Userinfo;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import model.service.UserInfoService;
@Component
public class UserInfoServiceImpl implements UserInfoService {
	//Spring 2.5 引入了 @Autowired 注释，
	//它可以对类成员变量、方法及构造函数进行标注，完成自动装配的工作。
	@Autowired
	private UserInfoDao userInfoDao;
	
	/* (non-Javadoc)
	 * @see service.impl.UserInfoService#createUserInfo(java.entity.UserInfo)
	 */
	public boolean createUserInfo(Userinfo  user){
		if(user==null) return false;
		try{
		userInfoDao.addUserInfo(user);
		return true;
		}catch(Exception e){
			e.printStackTrace();
			return false;
		}	
		
	}
	/* (non-Javadoc)
	 * @see service.impl.UserInfoService#getUserInfoAll(java.lang.Class)
	 */
	public List getUserInfoAll(Class user){
		List list = null;
		try{
			list= userInfoDao.getUserInfoAll(Userinfo.class);
		}catch(Exception e){
			e.printStackTrace();
			return null;
		}	
		return list;
	}
	
}

以上代码不连贯，只是针对配置文件做示例。过几天有空整理个实际的示例上来。
