Das Projekt wird mit dem Plugin javaswing+sqlserver+WindowBuilder abgeschlossen!
Dieser Artikel zeigt nur die Codes der Hauptschnittstelle und der Patientendateischnittstelle. Die Codeideen der anderen drei Schnittstellen sind dieselben. Sie können versuchen, sie selbst einzugeben
1. Erstellen Sie eine Datenbank
Tabelle 1: Patientenakte (Patient)
Tabelle 2: Arztinformationen (Arzt)
Tabelle 3: Abteilungsinformationen (Abteilung)
Tabelle 4: Krankenakten (Precord)
ER-Diagramm
2. Stellen Sie eine Verbindung zur Datenbank her
import java.io.IOError;
import java.io.IOException;
import java.sql.*;
import java.util.*;
public class DButils {
public static Connection getconnection() {
Connection con=null;
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection("jdbc:sqlserver://127.0.0.1:1433;DatabaseName=医院管理系统", "sa", "123456");
}
catch (ClassNotFoundException e) {
e.printStackTrace();
}catch (SQLException d){
d.printStackTrace();
}
return con;
}
public static void closeAll(Connection con, Statement st, ResultSet set){
try{
if(set!=null)
set.close();
if(st!=null)
st.close();
if(con!=null)
con.close();
}
catch (SQLException e){
e.printStackTrace();
}
}
}3. Erstellen Sie die Hauptschnittstelle
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class Window extends JFrame {
JButton button1;
JButton button2;
JButton button3;
JButton button4;
public Window(){
super("医院管理系统");
setBounds(300,300,600,400);
ImageIcon img=new ImageIcon("img/beijing.jpg");
JLabel jLabel=new JLabel(img);
this.getLayeredPane().add(jLabel,new Integer(Integer.MIN_VALUE));
jLabel.setBounds(0,0,img.getIconWidth(),img.getIconHeight());
JPanel panel=new JPanel();
button1=new JButton("病人档案");
button2=new JButton("科室信息");
button3=new JButton("医生信息");
button4=new JButton("就医档案");
button1.setBounds(250,40,100,50);
button2.setBounds(250,110,100,50);
button3.setBounds(250,180,100,50);
button4.setBounds(250,250,100,50);
button1.addActionListener(new MyActionListener());
button2.addActionListener(new MyActionListener());
button3.addActionListener(new MyActionListener());
button4.addActionListener(new MyActionListener());
panel.setLayout(null);
panel.add(jLabel);
panel.add(button1);
panel.add(button2);
panel.add(button3);
panel.add(button4);
setContentPane(panel);
setVisible(true);
}
//内部类对按钮事件进行处理
class MyActionListener implements ActionListener{
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand().equals("病人档案")){
PatientDangan frame = new PatientDangan();
}
if(e.getActionCommand().equals("科室信息")){
DepartmentPage departmentPage=new DepartmentPage();
}
if(e.getActionCommand().equals("医生信息")){

}
if(e.getActionCommand().equals("就医档案")){
PrecordPage precordPage=new PrecordPage();
}
}
}
public static void main(String[] args) {
new Window();
}
}
4. Erstellen Sie eine ORM-Entitätsklasse und eine Dao-Klasse (am Beispiel von Patientenakten).
Erstellen Sie eine Patient-Klasse (mit get- und set-Methoden)
import javax.xml.crypto.Data;
import java.sql.Date;
public class Patient {
int Pno;
String Pname;
String Psex;
String Pbirthday;
String area;
String condition;
int prepay;
String respon_doctor;
public Patient(){
}
public Patient(int pno, String pname,String psex, String pbirthday, String area, String condition, int prepay, String respon_doctor) {
Pno = pno;
Pname=pname;
Psex = psex;
this.Pbirthday = pbirthday;
this.area = area;
this.condition = condition;
this.prepay = prepay;
this.respon_doctor = respon_doctor;
}
public int getPno() {
return Pno;
}
public void setPno(int pno) {
Pno = pno;
}
public void setPname(String pname) {
Pname=pname;
}
public void setPsex(String psex) {
Psex = psex;
}
public String getPbirthday() {
return Pbirthday;
}
public void setPbirthday(String pbirthday) {
Pbirthday = pbirthday;
}
public String getArea() {
return area;
}
public String getPname() {
return Pname;
}
public void setArea(String area) {
this.area = area;
}
public String getCondition() {
return condition;
}
public void setCondition(String condition) {
this.condition = condition;
}
public int getPrepay() {
return prepay;
}
public void setPrepay(int prepay) {
this.prepay = prepay;
}
public String getRespon_doctor() {
return respon_doctor;
}
public void setRespon_doctor(String respon_doctor) {
this.respon_doctor = respon_doctor;
}
@Override
public String toString() {
return "Patient{" +
"Pno=" + Pno +
