引言
筆者最近剛學完java程式設計的基礎，是以嘗試做了一個簡單的學生管理系統，主要實作了學生資訊表的增删改查，如有不足之處，敬請各位讀者批評指正。如下是效果圖：
大緻思路如下：1、建立一個學生類 2、編寫學生類的是實作接口 3、編寫接口實作類 4、連接配接資料庫 5、使用SWI制作界面
一、定義學生類
public class Student {
private int Sno;//學号
private String Sname;//姓名
private int age;//年齡
private String gender;//性别
private String department;//系别
private String courseSelected;//選課情況
public Student() {
super();
}
public Student(int sno, String sname, int age, String gender, String department, String courseSelected) {
super();
this.Sno = sno;
this.Sname = sname;
this.age = age;
this.gender = gender;
this.department = department;
this.courseSelected = courseSelected;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public int getSno() {
return Sno;
}
public void setSno(int sno) {
this.Sno = sno;
}
public String getSname() {
return Sname;
}
public void setSname(String sname) {
this.Sname = sname;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
public String getCourseSelected() {
return courseSelected;
}
public void setCourseSelected(String courseSelected) {
this.courseSelected = courseSelected;
}
@Override
public String toString() {
return "Student [Sno=" + Sno + ", Sname=" + Sname + ", age=" + age + ", gender=" + gender + ", department="
+ department + ", courseSelected=" + courseSelected + "]";
}
}
二、編寫學生接口
public interface IStudentDao {
//查詢所有學生的資訊
public ArrayList<Student> selectStudentAll();
//查詢單個學生的資訊
public Student selectStudent(int sno);
//插入一條學生記錄
public boolean insertStudent(Student s);
//删除一條學生記錄
public boolean deleteStudent(int sno);
//修改某條學生記錄的資訊
public boolean updateStudent(Student s);
}
三、連接配接資料庫，編寫JDBC的工具類
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;
public class DBUtil {
private static Properties proper=new Properties();
/**
* 靜态代碼塊
*/
static {
try {
//加載properties檔案
proper.load(new FileInputStream("config/db.properties"));
//1 加載外部JDBC驅動程式
Class.forName(proper.getProperty("driverClassName"));
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
/**
* 擷取連接配接
* @return
*/
public static Connection getConnection() {
try {
//建立連接配接
Connection con=DriverManager.getConnection(proper.getProperty("url")
,proper.getProperty("username"),proper.getProperty("password"));
return con;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
/**
*擷取Statement對象
*/
public static Statement getStatement(Connection con) {
try {
return con.createStatement();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
/**
* 擷取PreparedStatement對象
*/
public static PreparedStatement getPreparedStatement(Connection con,String sql) {
try {
return con.prepareStatement(sql);
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
/**
* 關閉資源
*/
public static void close(Connection con,Statement stat,ResultSet rs) {
if(rs!=null) {
try {
rs.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(stat!=null) {
try {
stat.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(con!=null) {
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void close(Connection con,Statement stat) {
if(stat!=null) {
try {
stat.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(con!=null) {
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void close(Connection con) {
if(con!=null) {
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void close(Connection con,PreparedStatement stat,ResultSet rs) {
if(rs!=null) {
try {
rs.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(stat!=null) {
try {
stat.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(con!=null) {
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void close(Connection con,PreparedStatement stat) {
if(stat!=null) {
try {
stat.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(con!=null) {
try {
con.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
三、編寫接口實作類
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;

Statement stat = null;
ResultSet rs = null;
try {
//1、擷取連接配接
con = DBUtil.getConnection();
//2、建立Statement對象
stat = DBUtil.getStatement(con);
//3、定義SQL語句
String sql = "select * from Student order by Sno";
//傳回查詢到的結果集
rs = stat.executeQuery(sql);
ArrayList<Student> stuList = new ArrayList<Student>();
while(rs.next()) {
Student stu = new Student();

stu.setCourseSelected(rs.getString("courseSelected"));
stuList.add(stu);
}
return stuList;
} catch (SQLException e) {
e.printStackTrace();
} finally {
//關閉資源
DBUtil.close(con, stat, rs);
}
return null;
}
@Override
public Student selectStudent(int sno) {

PreparedStatement stat = null;
ResultSet rs = null;
try {

stu.setGender(rs.getString("gender"));

stu.setCourseSelected(rs.getString("courseSelected"));
}
return stu;
} catch (SQLException e) {
e.printStackTrace();
} finally {
DBUtil.close(con, stat, rs);
}
return null;
}
@Override
public boolean insertStudent(Student s) {
Connection con = null;

try {

if(stat.executeUpdate()>0) {
return true;
}
} catch (SQLException e) {

}
return false;
}
@Override

}
}
四、下載下傳WindowBuilder插件并安裝，建立一個JFram檔案，命名為StudentInformationFrame,在design界面中設定如下布局：
設定好布局之後，點選Source就會自動生成如下代碼：
