练习点设计:添加、删除、修改
一、语言和环境
- 实现语言:JAVA语言。
- 环境要求:MyEclipse/Eclipse + Tomcat + MySql。
- 使用技术:
Jsp
+Servle
t+JavaBean
或SpringMVC
+Spring
+Mybatis
。
二、实现功能
为了方便学校对图书进行管理,开发一套BS结构的图书信息管理系统,主要功能如下:
- 首页默认显示所有图书信息,并且按添加时间降序排列。
(1)按添加时间降序排列。
(2)底部显示添加书籍按钮。
- 点击“添加书籍”链接,跳转至书籍添加界面。
(1)添加时间默认新增时取当前时间即可。
3. 用户输入完整信息提交以后,要求自动跳转至列表界面,此时列表界面显示新增的书籍信息(按添加时间降序排列,应该在第一条)。
4. 用户点击“列表”界面中的删除超链接,执行删除操作,然后列表进行自动刷新。
5. 用户点击“列表”界面中的修改超链接,跳转到修改页面,并在该页面回显需要修改的书籍信息.
、
三、数据库设计
- 创建数据库(
person_db
)。 - 创建数据表(
tb_person
),结构如下。
字段名 | 说明 | 字段类型 | 长度 | 备注 |
---|---|---|---|---|
id | 编号 | int | 主键,自增,增量为1 | |
BookName | 书籍名称 | varchar | 50 | 不能为空 |
author | 作者 | varchar | 10 | 不能为空 |
pages | 页数 | Int | 不能为空 | |
createTime | 创建时间 | datetime | 不能为空 |
四、推荐实现步骤
- JSP版本的实现步骤如下:
(1)按以上数据库要求建库、建表,并添加测试数据(不少于5条,测试数据不需要和上图一致)。
(2)创建Web工程并创建各个包,导入工程所需的jar文件。
(3)创建Book实体类。
(4)创建Servlet获取用户不同的请求,并将这些请求转发至业务处理层相应的业务方法。
(5)创建业务处理层,在其中定义业务方法,实现系统需求,在这些业务方法中需要执行DAO方法。
(6)创建BaseDAO工具类,使用JDBC完成数据表数据的查询、删除、添加的功能方法代码。
(7)编写JSP页面展示数据的查询结果。
2.SSM版本的实现步骤如下:
(1)创建数据库,创建数据表,添加测试数据(不少于5条,测试数据不需要和上图一致)。
(2)创建Web工程并创建各个包,导入工程所需的jar文件。
(3)添加相关SSM框架支持。
(4)配置项目所需要的各种配置文件(mybatis配置文件、spring配置文件、springMVC配置文件)。
(5)创建实体类。
(6)创建MyBatis操作数据库所需的Mapper接口及其Xml映射数据库操作语句文件。
(7)创建业务逻辑相应的接口及其实现类,实现相应的业务,并在类中加入对DAO/Mapper的引用和注入。
(8)创建Controller控制器类,在Controller中添加对业务逻辑类的引用和注入,并配置springMVC配置文件。
(9)创建相关的操作页面,并使用CSS对页面进行美化。
(10)实现页面的各项操作功能,操作要人性化。
(11)调试运行成功后导出相关的数据库文件并提交。
五、实现代码
1、MySQL数据库
person_db.sql
/* Date: 2021-07-20 12:46:17 */
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for `tb_person`
-- ----------------------------
DROP TABLE IF EXISTS `tb_person`;
CREATE TABLE `tb_person` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`BookName` varchar(50) NOT NULL,
`author` varchar(10) NOT NULL,
`pages` int(11) NOT NULL,
`createTime` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of tb_person
-- ----------------------------
INSERT INTO `tb_person` VALUES ('1', '《红楼梦》', '曹雪芹', '542', '2021-07-20 10:44:26');
INSERT INTO `tb_person` VALUES ('2', '《水浒传》', '施耐庵', '652', '2021-07-20 10:44:57');
INSERT INTO `tb_person` VALUES ('3', '《镜花缘》', '李汝珍', '441', '2021-07-20 10:45:59');
INSERT INTO `tb_person` VALUES ('5', '《西游记》', '吴承恩', '5000', '2021-07-20 12:42:43');
INSERT INTO `tb_person` VALUES ('7', '《三国演义》', '罗贯中', '10000', '2021-07-20 12:42:07');
