1.团队课程设计博客链接
2.个人负责模块说明
查询和修改功能
3.个人代码提交记录
4.自己负责模块或任务详细说明
代码结构为：
，DB包为数据库操作，sims包为操作界面以及各个功能。
本人负责的主要功能展示：
一．查询功能
查询界面：
按姓名查询：
运行结果：
按学号查询：
运行结果与按姓名查询一样。
当数据库中没有所要查询人的信息的时候：
主要代码：
查询：
private void SearchButActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_LoginActionPerformed
String[][] strs = Search.serach(Searchname.getText(),Searchstuno.getText());
if(strs[0][0]==null){
JOptionPane.showMessageDialog(null, "查无此人");
Searchname.setText("");
Searchstuno.setText("");
}
else{
new SInfor(strs).setVisible(true);
this.setVisible(false);
}
用二维数组显示数据库信息：
public SInfor(String[][] strs) {
this.strs = strs;
initComponents();
Vector<String> columnNames = new Vector<>();
columnNames.add("学号");
columnNames.add("姓名");
columnNames.add("性别");
columnNames.add("生日");
columnNames.add("政治面貌");
columnNames.add("地址");
columnNames.add("电话");
columnNames.add("宿舍号");
Vector<Vector<String>> rowData = new Vector<Vector<String>>();
for (int i = 0; i < 100; i++) {
Vector<String> rowStrings = new Vector<>();
for (int j = 0; j < 8; j++) {
rowStrings.add(strs[i][j]);
}
rowData.add(rowStrings);
}
jTable2 = new JTable(rowData, columnNames);
jScrollPane2.setViewportView(jTable2);//滚动面板
}
查询语句：
public static String[][] serach(String name,String stuno){
if(name.length()!=0){
String str = "select * from sims where name= \'"+name+"\';";
String[][] strs = new String[100][8];
try{
ResultSet resultSet = DBUtil.query(str);//str->数据库
int cnt = 0;
while (resultSet.next()) {
for (int i = 0; i < 8; i++) {
strs[cnt][i] = resultSet.getString(i + 1);
}
cnt++;
}
}catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return strs;
}
操作数据库，返回结果集：
public static ResultSet query(String sql) throws SQLException, ClassNotFoundException {
Class.forName("com.mysql.jdbc.Driver");
// 1.获得数据库的连接
Connection conn = DriverManager.getConnection(URL, NAME, PASSWORD);
// 2.通过数据库的连接操作数据库，实现增删改查
Statement stmt = conn.createStatement();
try {
return stmt.executeQuery(sql);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
}
二．修改功能
修改界面：
性别输入错误时：
生日输入错误时：
确认修改：
修改成功：
修改后：
主要代码：
查询：
private void okActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_okActionPerformed
String str = "select * from sims where stuno = \'"+getstuno.getText().trim()+"\';";
String[][] strs = Strsselect.select(str);
if(strs[0][0]!=null){
AModifystu adm = new AModifystu(strs);
adm.setVisible(true);
this.setVisible(false);
}else{
JOptionPane.showMessageDialog(null, "查无此人!");
getstuno.setText("");
}
数据库修改：
public class Modify {
public static void modify(String stuno, String name, String gender, String birthdate, String poutlook,
String address, String phone, String dormitory){
String str = "update sims set stuno = \'" + stuno + "\',name = \'"+name+"\',gender=\'" + gender + "\'," + "birthdate=\'" + birthdate
+ "\'," + "poutlook=\'" + poutlook + "\'," + "address=\'" + address + "\'," + "phone=\'" + phone
+ "\'," + "dormitory=\'" + dormitory + "\' " + "where\'" + name + "\';";
try {
DBUtil.exec(str);
JOptionPane.showMessageDialog(null, "修改成功！");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
// e.printStackTrace();
JOptionPane.showMessageDialog(null, "修改成功！");
}
}
}
判断修改输入格式：
private void modifyActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_modifyActionPerformed
String[] str = bir.getText().split("-");
String birthday = "" ;
for (int i = 0; i < str.length; i++) {
birthday += str[i];
}
if(stuno.getText().length()==0)
JOptionPane.showMessageDialog(null, "学号不能为空!");
else if(Search.isNumer(stuno.getText())==false)
JOptionPane.showMessageDialog(null, "学号格式有误，请重新输入");
else if(name.getText().length()==0)
JOptionPane.showMessageDialog(null, "姓名不能为空!");
else if(gender.getText().length()==0)
JOptionPane.showMessageDialog(null, "性别不能为空!");
else if(gender.getText().length()>1){
JOptionPane.showMessageDialog(null, "性别格式有误，请输入m/f");
gender.setText("");
}
else if (bir.getText().length()==0){
JOptionPane.showMessageDialog(null, "生日不能为空!");
}
else if((bir.getText().length()!=0&&Search.isNumer(birthday)==false)||bir.getText().length()!=10){
JOptionPane.showMessageDialog(null, "生日格式有误，请输xxxx-xx-xx格式");
bir.setText("");
}else if(Integer.parseInt(str[1])>12){
JOptionPane.showMessageDialog(null, "月份输入有误");
bir.setText("");
}
else if(Integer.parseInt(str[2])>31){
JOptionPane.showMessageDialog(null, "日期输入有误");
bir.setText("");
}
else if(Search.isNumer(phone.getText())==false){
JOptionPane.showMessageDialog(null, "电话号码格式有误!");
phone.setText("");
} else{
int yes =JOptionPane.showConfirmDialog(this, "确认修改？", "提示",JOptionPane.YES_NO_OPTION);
if(yes==JOptionPane.YES_OPTION){
Modify.modify(stuno.getText(), name.getText(), gender.getText(),birthday,
poutlook.getText(), address.getText(), phone.getText(), dormitory.getText());
}
else{
}
}
