目录
零、项目功能实现
1、总功能
对界面中的表格进行点击可以对其姓名、年龄、性别、所在地区等进行修改，点击添加校友可以对其进行添加，返回到表格界面时，对数据进行更新。
2、代码操作解释
dao：对各自管理的信息进行增删改查的操作，定义函数操作
model：对需要的信息元素进行声明，以及getter和setter的函数，以及构造函数对对象进行设置
util：工具类-》对数据库进行连接、对字符串是否为空进行判断
view：界面设计以及对应代码操作的调用
3、对于界面的操作设置
均可以在eclipse中的插件windowbuilder中进行对应的设置，操作简单，多多操作看看代码就可以实现
4、表格与数据库中的数据进行连接
需要设置专门的fillsalumnus等的函数对其进行连接，将表格进行填充，代码在下
public void fillsalumnus(Alumnus alumnus) {
DefaultTableModel dtm = (DefaultTableModel) table.getModel();
dtm.setRowCount(0);
Connection con = null;
try {
con = dbUtil.getCon();//获取数据库的连接
ResultSet rs = alumnusDao.alumnusList(con, alumnus);
while (rs.next()) {
Vector v = new Vector();
v.add(rs.getInt("aid"));
v.add(rs.getString("aname"));
v.add(rs.getInt("aage"));
v.add(rs.getString("agender"));
v.add(rs.getString("afrom"));
dtm.addRow(v);
}//填充表格
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
dbUtil.closeCon(con);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}5、jtable的一些小小操作代码
获取鼠标点击的表格的行数：
注意：表格中每一行的元素，列是从下标0开始获取，下为得到表格第hang行第0列的元素值等等，注意数据类型的对应
int aid = (int)this.table.getValueAt(hang,0);
String aname = (String) this.table.getValueAt(hang,1);
int aage;
aage = (int)this.table.getValueAt(hang,2);
String agender = (String) this.table.getValueAt(hang,3);
String afrom = (String) this.table.getValueAt(hang,4);
String achieve = this.textField_1.getText();//获取文本框textField_1中的字符串6、界面背景设置
选取jlable等标签（将其大小拉至所需界面大小，可以记住），把文本去掉，设置其icon（可以选取绝对路径，图片大小与jlable的框框大小一致就不用调节大小了，最省力的办法）
一、运行界面展示
二、部分代码展示及个人理解

}
//展示校友信息

1、mysql下载安装：这边建议下载最简单的mysql文件夹
csdn上面搜索下载安装建议就可以直接搜到
2、eclipse的插件window builder下载建议：重新下载最新版的eclipse再进行下载安装
3、idea自带的数据库连接是真的很舒服
四、总结
怎么说捏，实训下来，总的来说，就是没有什么太大的用处，只是给我熬夜多了一个理由。可以借此多多认识身边的大佬吧，看看代码，代课老师应该有对应的代码分享，什么图书管理系统啊，学生信息管理系统啊，代码都有相似的地方，如果想做得出彩，可以多多设计一下界面，毕竟这个windobuilder自带的皮肤包是真的不怎么好看，可以多多搜索看看怎么设置前端，这个小小的项目还有很多可以改善的地方，代码仅供参考，具体设计还是有一个美工很厉害的大佬带着比较好哈。
