4. 实现添加产品操作

4.1 编写控制层

@Controller
@RequestMapping("/product")
public class ProductController {
    @Autowired
    private ProductService productService;
    
    /**
     * 添加产品
     * @param product
     * @return
     * @throws Exception
     */
    @RequestMapping("/save.do")
    public String save(Product product) throws Exception {
        productService.save(product);
        return "redirect:findAll.do";
    }

    /**
     * 查询所有产品
     * @return
     * @throws Exception
     */
    @RequestMapping("/findAll.do")
    public ModelAndView findAll() throws Exception {
        ModelAndView modelAndView = new ModelAndView();
        List<Product> products = productService.findAll();
        modelAndView.addObject("productList",products);
        modelAndView.setViewName("product-list");

        return modelAndView;
    }
}

4.2 编写业务层接口和实现类

public interface ProductService {
    /**
     * 查询所有产品
     * @return
     * @throws Exception
     */
    List<Product> findAll() throws Exception;

    /**
     * 添加产品
     * @param product
     * @throws Exception
     */
    void save(Product product) throws Exception;
}


@Transactional
@Service("productService")
public class ProductServiceImpl implements ProductService {
    @Autowired
    private ProductDao productDao;

    /**
     * 查询所有产品
     * @return
     * @throws Exception
     */
    @Override
    public List<Product> findAll() throws Exception {
        return productDao.findAll();
    }

    /**
     * 添加产品
     * @param product
     * @throws Exception
     */
    @Override
    public void save(Product product) throws Exception {
        productDao.save(product);
    }
}

4.3 编写持久层接口

@Repository
public interface ProductDao {
    /**
     * 查询所有产品
     *
     * @return
     * @throws Exception
     */
    @Select("select * from product")
    List<Product> findAll() throws Exception;

    /**
     * 添加产品
     * @param product
     */
    @Insert("insert into product(productNum,productName,cityName,departureTime,productPrice,productDesc,productStatus) values(#{productNum},#{productName},#{cityName},#{departureTime},#{productPrice},#{productDesc},#{productStatus})")
    void save(Product product) throws Exception;
}

4.4 编写实体类

在 departureTime 字段上添加注解 @DateTimeFormat(pattern = “yyyy-MM-dd HH:mm”)，实现 String 类型转换为 Date 类型

/**
 * 产品实体类
 */
public class Product implements Serializable {
    private Integer id; // 主键
    private String productNum; // 产品编号，唯一
    private String productName; // 产品名称
    private String cityName; // 出发城市
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm")
    private Date departureTime; // 出发时间
    private String departureTimeStr; // 出发时间的字符串
    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; // 状态的字符串

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getProductNum() {
        return productNum;
    }

    public void setProductNum(String productNum) {
        this.productNum = productNum;
    }

    public String getProductName() {
        return productName;
    }

    public void setProductName(String productName) {
        this.productName = productName;
    }

    public String getCityName() {
        return cityName;
    }

    public void setCityName(String cityName) {
        this.cityName = cityName;
    }

    public Date getDepartureTime() {
        return departureTime;
    }

    public void setDepartureTime(Date departureTime) {
        this.departureTime = departureTime;
    }

    public String getDepartureTimeStr() {
        if (departureTime != null) {
            departureTimeStr = DateUtils.date2String(departureTime, "yyyy-MM-dd HH:mm:ss");
        }
        return departureTimeStr;
    }

    public void setDepartureTimeStr(String departureTimeStr) {
        this.departureTimeStr = departureTimeStr;
    }

    public double getProductPrice() {
        return productPrice;
    }

    public void setProductPrice(double productPrice) {
        this.productPrice = productPrice;
    }

    public String getProductDesc() {
        return productDesc;
    }

    public void setProductDesc(String productDesc) {
        this.productDesc = productDesc;
    }

    public Integer getProductStatus() {
        return productStatus;
    }

    public void setProductStatus(Integer productStatus) {
        this.productStatus = productStatus;
    }

    public String getProductStatusStr() {
        if (productStatus != null) {
            if (productStatus == 0) {
                productStatusStr = "关闭";
            }
            if (productStatus == 1) {
                productStatusStr = "开启";
            }
        }
        return productStatusStr;
    }

    public void setProductStatusStr(String productStatusStr) {
        this.productStatusStr = productStatusStr;
    }

    @Override
    public String toString() {
        return "Product{" +
                "id='" + id + '\'' +
                ", productNum='" + productNum + '\'' +
                ", productName='" + productName + '\'' +
                ", cityName='" + cityName + '\'' +
                ", departureTime=" + departureTime +
                ", departureTimeStr='" + departureTimeStr + '\'' +
                ", productPrice=" + productPrice +
                ", productDesc='" + productDesc + '\'' +
                ", productStatus=" + productStatus +
                ", productStatusStr='" + productStatusStr + '\'' +
                '}';
    }
}
