该项目用javaswing+sqlserver+WindowBuilder插件完成！
本文只展示主界面和病人档案界面代码，另外三个界面的代码思路也是一样的，可以自己尝试敲一下
一.建立数据库
表1：病人档案（Patient）
表2：医生信息（Doctor）
表3：科室信息（Department）
表4：就医档案（Precord）
E-R图
二.连接数据库
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();
}
}
}三.创建主界面
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")){
DoctorPage doctorPage=new DoctorPage();
}
if(e.getActionCommand().equals("就医档案")){
PrecordPage precordPage=new PrecordPage();
}
}
}
public static void main(String[] args) {
new Window();
}
}
四.创建ORM实体类和Dao类（已病人档案为例）
创建Patient类(要有get、set方法)
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 +
", Pname='" + Pname + '\'' +
", Psex='" + Psex + '\'' +
", Pbirthday=" + Pbirthday +
", area='" + area + '\'' +
", condition='" + condition + '\'' +
", prepay=" + prepay +
", respon_doctor='" + respon_doctor + '\'' +
'}';
}
public String getPsex() {
return Psex;
}
}
创建PatientDaolmpl
import sun.security.x509.DNSName;
import javax.xml.crypto.Data;
import java.sql.*;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;

pst.setString(5, patient.getArea());
pst.setString(6, patient.getCondition());
pst.setInt(7, patient.getPrepay());
pst.setString(8, patient.getRespon_doctor());
result = pst.executeUpdate();
} catch (SQLException e) {
e.printStackTrace();
} finally {
DButils.closeAll(con, pst, null);
}return result;
}
//查询档案
public Patient select(int pno) {
Connection con = null;
PreparedStatement pst = null;
ResultSet set = null;
Patient patient=null;
try {

pst = con.prepareStatement("select * from Patient where Pno=?");
pst.setInt(1, pno);

}
} catch (SQLException e) {
e.printStackTrace();
} finally {
DButils.closeAll(con, pst, set);
}
return patient;
}
//修改档案
public int update(Patient patient) {
Connection con = null;
PreparedStatement pst = null;
int result=0;
try {
con = DButils.getconnection();
pst = con.prepareStatement("update Patient set Pname=?,Psex=?,Pbirthday=?,area=?,condition=?,prepay=?,respon_doctor=? where Pno=?");
pst.setString(1, patient.getPname());
pst.setString(2, patient.getPsex());
pst.setString(3, patient.getPbirthday());
pst.setString(4, patient.getArea());
pst.setString(5, patient.getCondition());
pst.setInt(6, patient.getPrepay());
pst.setString(7, patient.getRespon_doctor());
pst.setInt(8, patient.getPno());
result=pst.executeUpdate();
} catch (SQLException e) {
e.printStackTrace();
} finally {
DButils.closeAll(con, pst, null);
}
return result;
}
//删除档案
public int delete(int pno){
Connection con=null;
PreparedStatement pst=null;
int result=0;
try {
con=DButils.getconnection();
pst=con.prepareStatement("delete from Patient where Pno=?");
pst.setInt(1,pno);
result=pst.executeUpdate();
}catch (SQLException e){
e.printStackTrace();
}finally {
DButils.closeAll(con,pst,null);
}
return result;
}
//查询所有
public List<Patient> selectAll() {
List<Patient> lists=new ArrayList<>();
Connection con=null;
PreparedStatement pst=null;
ResultSet set=null;
try{
con=DButils.getconnection();
pst=con.prepareStatement("select * from Patient");
set=pst.executeQuery();
while (set.next()){
int no = set.getInt("Pno");
String pname=set.getString("Pname");
String sex = set.getString("Psex");
String b = set.getString("Pbirthday");
String areas = set.getString("area");
String conditions = set.getString("condition");
int p = set.getInt("prepay");
String rd = set.getString("respon_doctor");
Patient patient=new Patient(no,pname,sex,b,areas,conditions,p,rd);
lists.add(patient);
}
return lists;
}catch (SQLException e){
e.printStackTrace();
}finally {
DButils.closeAll(con,pst,set);
}
return null;
}
