JavaSwing實(shí)現(xiàn)小型學(xué)生管理系統(tǒng)
更新時(shí)間：2022年02月24日 16:21:41 作者：一夜星塵
這篇文章主要為大家詳細(xì)介紹了JavaSwing實(shí)現(xiàn)小型學(xué)生管理系統(tǒng)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
本文實(shí)例為大家分享了JavaSwing實(shí)現(xiàn)小型學(xué)生管理系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下
在項(xiàng)目中建立四個(gè)包，分別是com.wu.JavaBean、com.wuJavaDao、com.wu.JavaService、com.wu.JavaView
數(shù)據(jù)庫表結(jié)構(gòu)
學(xué)生表只有四個(gè)屬性：學(xué)生姓名、學(xué)生性別、學(xué)生學(xué)號(主鍵)、學(xué)生班級
管理員表只有兩個(gè)屬性：管理員用戶名(主鍵)、管理員密碼
這里筆者為了簡單，學(xué)生表只寫了四個(gè)屬性，管理員表只寫了兩個(gè)屬性。
在JavaBean新建Student和Root類，如下：
Student.java:
package com.wu.JavaBean;
/**
?*?
* @date 2020年12月15日下午9:49:51
* @author 一夜星塵
?*/
public class Student {
?? ?private String name;
?? ?private String gender;
?? ?private String id;
?? ?private String team;
?? ?public Student() {}
?? ?public Student(String name,String gender,String id,String team) {
?? ??? ?this.name = name;
?? ??? ?this.id = id;
?? ??? ?this.team = team;
?? ??? ?this.gender = gender;
?? ?}
?? ?public String getName() {
?? ??? ?return name;
?? ?}
?? ?public void setName(String name) {
?? ??? ?this.name = name;
?? ?}
?? ?public String getGender() {
?? ??? ?return gender;
?? ?}
?? ?public void setGender(String gender) {
?? ??? ?this.gender = gender;
?? ?}
?? ?public String getId() {
?? ??? ?return id;
?? ?}
?? ?public void setId(String id) {
?? ??? ?this.id = id;
?? ?}
?? ?public String getTeam() {
?? ??? ?return team;
?? ?}
?? ?public void setTeam(String team) {
?? ??? ?this.team = team;
?? ?}
}Root.java:
package com.wu.JavaBean;
/**
?*?
* @date 2020年12月15日下午9:50:30
* @author 一夜星塵
?*/
public class Root {
?? ?private String username; // 賬號
?? ?private String password; // 密碼
?? ?private String ?superroot ; // 超級管理員身份 唯一一個(gè)
?? ?public Root(String username) {
?? ??? ?this.username = username;
?? ?}
?? ?public Root(String username,String password,String superroot) {?? ??? ?
?? ??? ?this.username = username;
?? ??? ?this.password = password;
?? ??? ?this.superroot = superroot;
?? ?}
?? ?public String getUsername() {
?? ??? ?return username;
?? ?}
?? ?public void setUsername(String username) {
?? ??? ?this.username = username;
?? ?}
?? ?public String getPassword() {
?? ??? ?return password;
?? ?}
?? ?public void setPassword(String password) {
?? ??? ?this.password = password;
?? ?}
?? ?public boolean isSuperRoot() {
?? ??? ?return superroot.equals("1"); // 1代表超級管理員
?? ?}
}建立數(shù)據(jù)庫連接DAO層，即在JavaDao包下建立JDBC.java，該程序只是控制數(shù)據(jù)庫的連接：
package com.wu.JavaDao;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
/**
* @date 2020年12月15日下午9:58:11
* @author 一夜星塵
*/
public class JDBC {
?? ?private Connection sqllink = null;
?? ?/**
?? ? * 獲取數(shù)據(jù)庫連接對象
?? ? * @return
?? ? * @throws Exception
?? ? */
?? ?public ?Connection ?getConnection() ?throws Exception{
?? ??? ?String DATABASE_DRIVER = "com.mysql.cj.jdbc.Driver";?
?? ??? ?String DATABASE_URL = "jdbc:mysql://127.0.0.1:3306/jdbc_db"+
?? ??? ?"?charcterEncoding=utf-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true";?
?? ??? ?String DATABASE_USER = "root";
?? ??? ?String DATABASE_PASSWORD = "root";
?? ??? ?
?? ??? ?try {
?? ??? ??? ?Class.forName(DATABASE_DRIVER); // 注冊驅(qū)動
?? ??? ??? ?sqllink = DriverManager.getConnection(DATABASE_URL,DATABASE_USER,DATABASE_PASSWORD); // 連接數(shù)據(jù)庫
?? ??? ??? ?return this.sqllink;
?? ??? ?}catch(SQLException e) {
?? ??? ??? ?e.printStackTrace();
?? ??? ??? ?System.out.println("連接數(shù)據(jù)庫異常"); // 錯(cuò)誤信息顯示到控制臺
?? ??? ??? ?return this.sqllink;
?? ??? ?}
?? ?}
?? ?/**
?? ? * 關(guān)閉數(shù)據(jù)庫連接對象
?? ? * @throws Exception
?? ? */
?? ?public void closeConnection() throws Exception{
?? ??? ?try {
?? ??? ??? ?if(this.sqllink != null) {
?? ??? ??? ??? ?this.sqllink.close();
?? ??? ??? ?}
?? ??? ?}catch(SQLException e) {
?? ??? ??? ?System.out.println("關(guān)閉數(shù)據(jù)庫連接異常");
?? ??? ?}
?? ?}
}com.wu.JavaBean和com.wu.JavaDao已經(jīng)全部完成了，接下來就是完成業(yè)務(wù)邏輯JavaService包下的實(shí)現(xiàn)

支持模糊查詢，即通過 屬性1=內(nèi)容1&屬性2=內(nèi)容2 可以配合%_兩個(gè)符號查詢
這里筆者為了簡單，沒有精雕細(xì)琢，讀者可以根據(jù)自己的需要修改即可。
以上就是本文的全部內(nèi)容，希望對大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
