     工作目标:实现卖家dao层的商品的增删改查(只能对自己发布的进行增删改查)。

     工作进程追踪:

                    ①创建了Shop类(卖家类)

                   ②创建了ShopDao的接口里面编写了 查看所有商品，根据商品货名查看商品，增加商品，删除商品和修改商品。

                   ③创建ShopDaoMapper的xml文件，在里面编写了查询所有商品，根据商品名,称查询商品，根据商品pid删除商品，根据商品pid修改商品的代码。

 

Shop.java

public class Shop {
 private Integer sid;  //卖家id
 private String s_code; //卖家账户
 private String s_password; //卖家密码
 private String s_name; //卖家姓名
 private String s_admin; //卖家管理员
 private String s_telephone; //卖家电话
 private String s_mail; //卖家邮箱
 private String s_address; //卖家地址
 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 {

   public Product getAllProduct(Product product);
   //根据货名查看商品
   public Product getProductById(String name);
   //增加商品
   public int createProduct(Product product);
   //删除商品
   public int deleteProduct(Integer pid);
   //修改商品
   public int updateProduct(Product product);
}
