Java Swing大作业--简易员工管理系统

@Java Swing简易员工管理系统

系统功能模块图

系统包括管理员登录页面和主页面设计，在主界面包括员工信息的增删改查功能。

系统实现环境说明

开发环境：eclipse 2022-03
Jdk版本：11
数据库：MySQL

数据库实现代码

1.创建数据库employees。

CREATE DATABASE employees;
USE employees;

2.创建管理员表admin并增加数据。

DROP TABLE IF EXISTS `admin`;
CREATE TABLE `admin`  (
  `ano` int(0) NOT NULL COMMENT '管理员号',
  `aname` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '账号',
  `password` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '密码',
  PRIMARY KEY (`ano`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
INSERT INTO `admin` VALUES (1, 'admin', 'admin');

3.创建员工信息表emp并增加数据。

DROP TABLE IF EXISTS `emp`;
CREATE TABLE `emp`  (
  `yno` int(0) NOT NULL AUTO_INCREMENT COMMENT '员工号',
  `yname` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '员工姓名',
  `sex` varchar(4) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '员工性别',
  `birth` date NULL DEFAULT NULL COMMENT '出生日期',
  `home` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '籍贯',
  `degree` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '学历',
  `salary` double(10, 2) NULL DEFAULT NULL COMMENT '薪水',
  `info` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '备注',
  PRIMARY KEY (`yno`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 9 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci ROW_FORMAT = Dynamic;
INSERT INTO `emp` VALUES (2, '王二', '男', '2000-10-11', '湖南长沙', '初中', 2300.00, '');
INSERT INTO `emp` VALUES (4, '张三', '男', '1996-08-27', '湖北武汉', '初中', 2300.00, '平时兢兢业业');
INSERT INTO `emp` VALUES (5, '麻子', '男', '1994-09-13', '湖南怀化', '专科', 4500.00, '有一技之长');
INSERT INTO `emp` VALUES (6, '李四', '男', '1996-12-21', '湖南怀化', '高中', 3200.00, '');
INSERT INTO `emp` VALUES (7, '林黛玉', '女', '1998-08-12', '湖南株洲', '研究生', 6500.00, '工作认真负责，可堪大用');
INSERT INTO `emp` VALUES (8, '王小二', '男', '1999-02-03', '湖南常德', '高中', 4500.00, '做事认真');
INSERT INTO `emp` VALUES (9, '张晓', '女', '2000-02-13', '湖南岳阳', '高中', 4500.00, '工作认真负责，兢兢业业');
INSERT INTO `emp` VALUES (10, '顾枫熙', '女', '2000-03-16', '湖南株洲', '专科', 4500.00, '');

运行效果图

1.登录界面
此页面使用来实现管理员的登录。管理员通过输入账号和密码进行登录，点击登录会触发登录判断事件，首先判断用户是否填写账号和密码，如果账号或密码为空会弹窗提示不能为空，需要用户重新输入，当输入均不为空时会获取文本框内容来判断是否和数据库中的管理员账号密码一致。当用户输入错误时可以直接点击重置按钮对文本框内容进行清空操作。

2.主界面
管理员登录成功后跳转到系统主界面，管理员可在此进行相应操作。此界面包括以下功能：
1）员工信息添加功能：该功能可以添加新员工信息。其中员工号是自动增加，无需手动添加，员工姓名和籍贯为必填项，性别通过使用JRadioButton和ButtonGroup组件限制用户只能选择性别为男或女，默认性别为男，学历通过使用JComboBox下拉框限制规范填写学历信息，默认学历为文盲，此外出生日期填写应规范为“YYYY-MM-DD”或“YYYY.MM.DD”模式，否则添加失败。
2）员工信息查询功能：该功能可以通过对员工姓名的模糊查询，查询到所需员工的基本信息。若需查询所有员工信息，可在不填写搜索框的情况下点击搜索，即可查看到全部员工的基本信息。
3）员工信息修改功能：该功能可以修改选中员工的基本信息，其中员工号是不可修改信息，员工姓名和籍贯为必填项，此外出生日期填写应规范为“YYYY-MM-DD”或“YYYY.MM.DD”模式，否则修改失败。
4）员工信息删除功能：该功能可以删除选中员工的基本信息。
