一、数据库环境搭建
1.sql语句
CREATE TABLE product(
id VARCHAR(32) PRIMARY KEY,
productNum VARCHAR(50) NOT NULL,
productName VARCHAR(50),
cityName VARCHAR(50),
DepartureTime TIMESTAMP,
productPrice DOUBLE,
productDesc VARCHAR(500),
productStatus INT,
UNIQUE KEY(id,productNum)
)
INSERT INTO PRODUCT (id, productnum, productname, cityname, departuretime, productprice,
productdesc, productstatus)
VALUES ('676C5BD1D35E429A8C2E114939C5685A', 'xpt-002', '北京三日游', '北京', 20181010101000, 1200, '不错的旅行', 1);
INSERT INTO PRODUCT (id, productnum, productname, cityname, departuretime, productprice,
productdesc, productstatus)
VALUES ('12B7ABF2A4C544568B0A7C69F36BF8B7', 'xpt-003', '上海五日游', '上海', 20180425143000, 1800, '魔都我来了', 0);
INSERT INTO PRODUCT (id, productnum, productname, cityname, departuretime, productprice,
productdesc, productstatus)
VALUES ('9F71F01CB448476DAFB309AA6DF9497F', 'xpt-001', '北京三日游', '北京', 20181010101000, 1200, '不错的旅行', 1);
2.可视化效果
3.字段说明
二、maven工程搭建
1.首先创建父工程
2.创建父工程的子模块
创建方式和上述完全一致，依次命名为
2.1几大子模块
2.2web模块需要用maven模板项目
2.3最后效果
3.父工程pom.xml导入jar包

4domian模块中实体类创建
4.1创建含有如下属性的实体类
只给出属性名和类名，
getter和setter方法自行右键生成即可
public class Product {
private String id; // 主键
private String productNum; // 编号 唯一
private String productName; // 名称
private String cityName; // 出发城市
private Date departureTime; // 出发时间
private String departureTimeStr;
private double productPrice; // 产品价格
private String productDesc; // 产品描述
private Integer productStatus; // 状态 0 关闭 1 开启
private String productStatusStr;
}
4.2目录结构
5.dao模块接口配置
5.1接口代码
public interface IProductDao {
//查询所有的产品信息
public List<Product> findAll() throws Exception;
}
5.2目录结构
6.service模块创建接口和实现类
6.1接口代码
public interface IProductService {
public List<Product> findAll() throws Exception;
}
6.2实现类代码
@Service
@Transactional
public class ProductServiceImpl implements IProductService {
//服务层调用dao层
//等待被注入
@Autowired
private IProductDao productDao;
@Override
public List<Product> findAll() throws Exception {
return productDao.findAll();
}
}
6.3目录结构
7.配置文件
所有的配置都在web子模块中进行，但是web模块是基于maven骨架工程创建的，所以需要先完善它的目录。
7.1完善目录
7.2配置applicationContext.xml
这是spring的核心配置文件

8.web模块新建ProductController类
8.1ProductController
@Controller
@RequestMapping("/product")
public class ProductController {
//控制器应该调用service层
@Autowired
private IProductService productService;
//.do是个人习惯
@RequestMapping("/findAll.do")
public ModelAndView findAll() throws Exception {
ModelAndView mv = new ModelAndView();
List<Product> products = productService.findAll();
mv.addObject("",products);
mv.setViewName("");
return mv;
}
}
8.2目录结构
9.基本功能测试
9.1页面的支持
- 效果：
10.main.jsp（主页）
三、添加产品流程
1.流程分析
2.代码实现
2.1前端代码解释
2.2后端代码实现
3.功能效果
