     工做目標:實現賣家dao層的商品的增刪改查(只能對本身發佈的進行增刪改查)。

     工做進程追蹤:

                    ①建立了Shop類(賣家類)

                   ②建立了ShopDao的接口裏面編寫了 查看全部商品，根據商品貨名查看商品，增長商品，刪除商品和修改商品。

                   ③建立ShopDaoMapper的xml文件，在裏面編寫了查詢全部商品，根據商品名,稱查詢商品，根據商品pid刪除商品，根據商品pid修改商品的代碼。

 

Shop.java

public class Shop {
 private Integer sid;  //賣家id
 private String s_code; //賣家帳戶
 private String s_password; //賣家密碼
 private String s_name; //賣家姓名
 private String s_admin; //賣家管理員
 private String s_telephone; //賣家電話
 private String s_mail; //賣家郵箱
 private String s_address; //賣家地址
 public Shop()
 {
	 
 }
public Integer getSid() {
	return sid;
}
public void setSid(Integer sid) {
	this.sid = sid;
}
public String getS_code() {
	return s_code;
}
public void setS_code(String s_code) {
	this.s_code = s_code;
}
public String getS_password() {
	return s_password;
}
public void setS_password(String s_password) {
	this.s_password = s_password;
}
public String getS_name() {
	return s_name;
}
public void setS_name(String s_name) {
	this.s_name = s_name;
}
public String getS_admin() {
	return s_admin;
}
public void setS_admin(String s_admin) {
	this.s_admin = s_admin;
}
public String getS_telephone() {
	return s_telephone;
}
public void setS_telephone(String s_telephone) {
	this.s_telephone = s_telephone;
}
public String getS_mail() {
	return s_mail;
}
public void setS_mail(String s_mail) {
	this.s_mail = s_mail;
}
public String getS_address() {
	return s_address;
}
public void setS_address(String s_address) {
	this.s_address = s_address;
}
}

 

ShopDao.java

public interface ShopDao {
   //查看全部商品
   public Product getAllProduct(Product product);
   //根據貨名查看商品
   public Product getProductById(String name);
   //增長商品
   public int createProduct(Product product);
   //刪除商品
   public int deleteProduct(Integer pid);
   //修改商品
   public int updateProduct(Product product);
}
