SpringMVC

SpringMVC+SpringJDBC+SpringTransaction

之前学习使用过Spring2.5以及和Hibernate和Struts2的集成，初步了解了Spring，业界对Spring的评价很高，我对其强大的功能只有蜻蜓点水般的体验，一直想学习接触一下Spring3.x，这会儿开始写了一个入门的SpringMVC+SpringJDBC和SpringTransaction的登陆案例，如同盲人摸象般地开始探索大象了。

至于Spring3的新特性，网上都有很多介绍，我看了，有很多东西没有实践过，所以一知半解，这里就不写了，那么就先找找感觉吧，开始我的编程之旅了...

看看我们的准备环境：
Spring3是基于JDK1.5的，对JDK1.6全面支持，所以编译Spring3.0必须使用JDK1.5以上，我用的是1.7版本的，数据库是MySQL5.0，开发工具是Meclipse8.5,。

1.工程名：spring3_learning，Jar包的准备：

这些jar包我都有上传，已经分类好了，可以直接去我的博客下载:http://download.csdn.net/detail/ysjian_pingcx/5335834

2.包结构的设计：

model包放的是与数据库有对应表的实体，vo包是一些Value Object用于辅助信息封装的，util放的是一些系统用到的工具类，controller放的是前段控制器
当模块多的时候，有必要在controller，dao，service，model前面加上模块名，便于管理和维护，此时可以讲util包加上system，
test是一个同等于src的目录，用于jUnit4测试的。

3.model的建立：
User：
[java] package com.meritit.ysjian.spring3learning.model;

import java.io.Serializable;
import java.util.Date;

public class User implements Serializable{
    private static final long serialVersionUID = -5271584436847697641L;

    private int userId;

    private String userName;

    private String password;

    private int credits;

    private String lastIp;

    private Date lastVisit;

    public String getLastIp() {
        return lastIp;
    }

    public void setLastIp(String lastIp) {
        this.lastIp = lastIp;
    }

    public Date getLastVisit() {
        return lastVisit;
    }

    public void setLastVisit(Date lastVisit) {
        this.lastVisit = lastVisit;
    }

    public int getUserId() {
        return userId;
    }

    public void setUserId(int userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

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

    public int getCredits() {
        return credits;
    }

    public void setCredits(int credits) {
        this.credits = credits;
    }

    @Override
    public String toString() {
        return "User [credits=" + credits + ", lastIp=" + lastIp
                + ", lastVisit=" + lastVisit + ", password=" + password
                + ", userId=" + userId + ", userName=" + userName + "]";
    }
}

package com.meritit.ysjian.spring3learning.model;

import java.io.Serializable;
import java.util.Date;

public class User implements Serializable{
private static final long serialVersionUID = -5271584436847697641L;

private int userId;

private String userName;

private String password;

private int credits;

private String lastIp;

private Date lastVisit;

public String getLastIp() {
return lastIp;
}

public void setLastIp(String lastIp) {
this.lastIp = lastIp;
}

public Date getLastVisit() {
return lastVisit;
}

public void setLastVisit(Date lastVisit) {
this.lastVisit = lastVisit;
}

public int getUserId() {
return userId;
}

public void setUserId(int userId) {
this.userId = userId;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public String getPassword() {
return password;
}

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

public int getCredits() {
return credits;
}

public void setCredits(int credits) {
this.credits = credits;
}

@Override
public String toString() {
  return "User [credits=" + credits + ", lastIp=" + lastIp
    + ", lastVisit=" + lastVisit + ", password=" + password
    + ", userId=" + userId + ", userName=" + userName + "]";
}
}LoginLog：
[java] package com.meritit.ysjian.spring3learning.model;
import java.io.Serializable;
import java.util.Date;

public class LoginLog implements Serializable{

    private static final long serialVersionUID = -1764224611964600980L;

    private int loginLogId;

    private int userId;

    private String ip;

    private Date loginDate;

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public Date getLoginDate() {
