畢設（一）

畢設（一）

校園商鋪
終於要開始做畢設了，太難了
前提是搭建maven,平臺用的是eclipse。
此處可百度看教程。
接下來開始重頭戲！!
o2o就當是這個項目的名字吧。

• 在此之前搞清楚各實體類的聯繫

微信賬號和本地賬號通過用戶信息的i聯繫在一起

商鋪信息和區域信息通過區域id連接
店鋪信息的店鋪id和店鋪類別做關聯

商品信息通過product.id與商品類別相關聯
詳情圖片通過product.id與商品信息相關聯

1.實體類設計

區域設計

區域類代碼
在one這個項目下的Java Resources下的src/main/java創建實體包，名爲com.one.entity,在這個包下面創建Area.java

詳細代碼如下：

package com.one.entity;

import java.util.Date;

public class Area {
   //ID
	private Integer areaId;
   //名稱
    private String areaName;
    //權重(做排序)
    private Integer priority;
    //創建時間
    private Date createTime;
    //更新時間
    private Date lastEditTime;
	public Integer getAreaId() {
		return areaId;
	}
	public void setAreaId(Integer areaId) {
		this.areaId = areaId;
	}
	public String getAreaName() {
		return areaName;
	}
	public void setAreaName(String areaName) {
		this.areaName = areaName;
	}
	public Integer getPriority() {
		return priority;
	}
	public void setPriority(Integer priority) {
		this.priority = priority;
	}
	public Date getCreateTime() {
		return createTime;
	}
	public void setCreateTime(Date createTime) {
		this.createTime = createTime;
	}
	public Date getLastEditTime() {
		return lastEditTime;
	}
	public void setLastEditTime(Date lastEditTime) {
		this.lastEditTime = lastEditTime;
	}
    
}

區域類sql語句（在此之前先創建一個名爲"one”的數據庫）

CREATE TABLE `tb_area` (
`area_id`  int(2) NOT NULL AUTO_INCREMENT ,
`area_name`  varchar(200) NOT NULL ,
`priority`  int(2) NOT NULL DEFAULT '0' ,
`create_time`  datetime  DEFAULT NULL ,
`last_edit_time`  datetime DEFAULT NULL ,
PRIMARY KEY (`area_id`),
unique key `UK_AREA`(`area_name`)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

用戶設計

在one這個項目下的Java Resources下的src/main/java創建實體包，名爲com.one.entity,在這個包下面創建PersonInfo.java

詳細代碼如下：

package com.one.entity;

import java.util.Date;

public class PersonInfo {
 private Long userId;
 private String name;
 private String profileImg;
 private String email;
 private String gender;
 //用戶狀態
 private Integer enableStatus;
 //1.顧客 2.店家 3.超級管理員
 private Integer userType;
 private Date createTime;
 private Date lastEditTime;
public Long getUserId() {
	return userId;
}
public void setUserId(Long userId) {
	this.userId = userId;
}
public String getName() {
	return name;
}
public void setName(String name) {
	this.name = name;
}
public String getProfileImg() {
	return profileImg;
}
public void setProfileImg(String profileImg) {
	this.profileImg = profileImg;
}
public String getEmail() {
	return email;
}
public void setEmail(String email) {
	this.email = email;
}
public String getGender() {
	return gender;
}
public void setGender(String gender) {
	this.gender = gender;
}
public Integer getEnableStatus() {
	return enableStatus;
}
public void setEnableStatus(Integer enableStatus) {
	this.enableStatus = enableStatus;
}
public Integer getUserType() {
	return userType;
}
public void setUserType(Integer userType) {
	this.userType = userType;
}
public Date getCreateTime() {
	return createTime;
}
public void setCreateTime(Date createTime) {
	this.createTime = createTime;
}
public Date getLastEditTime() {
	return lastEditTime;
}
public void setLastEditTime(Date lastEditTime) {
	this.lastEditTime = lastEditTime;
}
 
}

用戶類sql語句

CREATE TABLE `tb_person_info` (
`user_id`  int(10) NOT NULL AUTO_INCREMENT ,
`name`  varchar(32) DEFAULT NULL ,
`profile_img` varchar(1024) DEFAULT NULL ,
`email`  varchar(1024) DEFAULT NULL ,
`gender`  varchar(2) DEFAULT NULL ,
`enable_status`  int(2)NOT NULL DEFAULT '0' COMMENT '0:禁止使用本商城,1:允許使用本商城',
`user_type`  int(2) NOT NULL DEFAULT '1' COMMENT '1:顧客,2:店家,3:超級管理員',
`create_time` datetime DEFAULT NULL,
`last_edit_time`  datetime DEFAULT NULL,
primary key(`user_id`)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8

賬號設計

與上邊同樣的道理，建立WechatAuth.java類

詳細代碼如下

package com.one.entity;

import java.util.Date;

public class WechatAuth {
 private Long wechatAuthId;
 private String openId;
 private Date createTime;
 //與個人信息表相連接
 private PersonInfo personInfo;
public Long getWechatAuthId() {
	return wechatAuthId;
}
public void setWechatAuthId(Long wechatAuthId) {
	this.wechatAuthId = wechatAuthId;
}
public String getOpenId() {
	return openId;
}
public void setOpenId(String openId) {
	this.openId = openId;
}
public Date getCreateTime() {
	return createTime;
}
public void setCreateTime(Date createTime) {
	this.createTime = createTime;
}
public PersonInfo getPersonInfo() {
	return personInfo;
}
public void setPersonInfo(PersonInfo personInfo) {
	this.personInfo = personInfo;
}
 
}

對應的sql語句爲

CREATE TABLE `tb_wechat_auth` (
`wechat_auth_id`  int(10) NOT NULL AUTO_INCREMENT ,
`user_id`  int(10) NOT NULL ,
`open_id`  varchar(1024) NOT NULL ,
`create_time` datetime DEFAULT NULL,
primary key(`wechat_auth_id`),
constraint `fk_wechatauth_profile` foreign key(`user_id`) references `tb_person_info`(`user_id`)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

建立LocalAuth.java類

詳細代碼如下

package com.one.entity;

import java.util.Date;

public class LocalAuth {
  private Long localAuthId;
  private String username;
  private String password;
  private Date createTime;
  private Date lastEditTime;
  private PersonInfo personInfo;
public Long getLocalAuthId() {
	return localAuthId;
}
public void setLocalAuthId(Long localAuthId) {
	this.localAuthId = localAuthId;
}
public String getUsername() {
	return username;
}
public void setUsername(String username) {
	this.username = username;
}
public String getPassword() {
	return password;
}
public void setPassword(String password) {
	this.password = password;
}
public Date getCreateTime() {
	return createTime;
}
public void setCreateTime(Date createTime) {
	this.createTime = createTime;
}
public Date getLastEditTime() {
	return lastEditTime;
}
public void setLastEditTime(Date lastEditTime) {
	this.lastEditTime = lastEditTime;
}
public PersonInfo getPersonInfo() {
	return personInfo;
}
public void setPersonInfo(PersonInfo personInfo) {
	this.personInfo = personInfo;
}
  
}

所對應的sql語句如下:

CREATE TABLE `tb_local_auth` (
`local_auth_id`  int(10) NOT NULL AUTO_INCREMENT ,
`user_id`  int(10) NOT NULL ,
`username`  varchar(128) NOT NULL ,
`password`  varchar(128) NOT NULL ,
`create_time` datetime DEFAULT NULL,
`last_edit_time` datetime DEFAULT NULL,
primary key(`local_auth_id`),
UNIQUE KEY `uk_local_profile`(`username`), 
constraint `fk_localauth_profile` foreign key(`user_id`) references `tb_person_info`(`user_id`)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

增加唯一索引sql語句：目的在於提升查詢效能

alter table tb_wechat_auth add unique index(open_id);

頭條類創建

同理創建HeadLine.java

詳細代碼如下:

package com.one.entity;

import java.util.Date;

public class HeadLine {
  private Long lineId;
  private String lineName;
  private String lineLink;
  private String lineImg;
  private Integer priority;
  //0.不可用1.可用
  private Integer enableStatus;
  private Date createTime;
  private Date lastEditTime;
public Long getLineId() {
	return lineId;
}
public void setLineId(Long lineId) {
	this.lineId = lineId;
}
public String getLineName() {
	return lineName;
}
public void setLineName(String lineName) {
	this.lineName = lineName;
}
public String getLineLink() {
	return lineLink;
}
public void setLineLink(String lineLink) {
	this.lineLink = lineLink;
}
public String getLineImg() {
	return lineImg;
}
public void setLineImg(String lineImg) {
	this.lineImg = lineImg;
}
public Integer getPriority() {
	return priority;
}
public void setPriority(Integer priority) {
	this.priority = priority;
}
public Integer getEnableStatus() {
	return enableStatus;
}
public void setEnableStatus(Integer enableStatus) {
	this.enableStatus = enableStatus;
}
public Date getCreateTime() {
	return createTime;
}
public void setCreateTime(Date createTime) {
	this.createTime = createTime;
}
public Date getLastEditTime() {
	return lastEditTime;
}
public void setLastEditTime(Date lastEditTime) {
	this.lastEditTime = lastEditTime;
}
  
}

對應sql語句

CREATE TABLE `tb_head_line` (
`line_id`  int(100) NOT NULL AUTO_INCREMENT ,
`line_name`  varchar(100) DEFAULT NULL ,
`line_link`  varchar(2000) NOT NULL ,
`line_img` varchar(2000) NOT NULL,
`priority` int(2) DEFAULT NULL,
`enable_status`int(2) NOT NULL DEFAULT '0',
`create_time` datetime DEFAULT NULL,
`last_edit_time` datetime DEFAULT NULL,
primary key(`line_id`)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8

店鋪類別

同理，建立ShopCategory.java

詳細代碼如下：

package com.one.entity;

import java.util.Date;

public class ShopCategory {
  private Long shopCategoryId;
  private String shopcategoryName;
  private String shopcategoryDesc;
  private String shopCategoryImg;
  private Integer priority;
  private Date createTime;
  private Date lastEditTime;
  private ShopCategory parent;
public Long getShopCategoryId() {
	return shopCategoryId;
}
public void setShopCategoryId(Long shopCategoryId) {
	this.shopCategoryId = shopCategoryId;
}
public String getShopcategoryName() {
	return shopcategoryName;
}
public void setShopcategoryName(String shopcategoryName) {
	this.shopcategoryName = shopcategoryName;
}
public String getShopcategoryDesc() {
	return shopcategoryDesc;
}
public void setShopcategoryDesc(String shopcategoryDesc) {
	this.shopcategoryDesc = shopcategoryDesc;
}
public String getShopCategoryImg() {
	return shopCategoryImg;
}
public void setShopCategoryImg(String shopCategoryImg) {
	this.shopCategoryImg = shopCategoryImg;
}
public Integer getPriority() {
	return priority;
}
public void setPriority(Integer priority) {
	this.priority = priority;
}
public Date getCreateTime() {
	return createTime;
}
public void setCreateTime(Date createTime) {
	this.createTime = createTime;
}
public Date getLastEditTime() {
	return lastEditTime;
}
public void setLastEditTime(Date lastEditTime) {
	this.lastEditTime = lastEditTime;
}
public ShopCategory getParent() {
	return parent;
}
public void setParent(ShopCategory parent) {
	this.parent = parent;
}
  
}

對應sql語句

CREATE TABLE `tb_shop_category` (
`shop_category_id`  int(11) NOT NULL AUTO_INCREMENT ,
`shop_category_name`  varchar(100)NOT NULL DEFAULT '' ,
`shop_category_desc`  varchar(1000) DEFAULT '',
`shop_category_img` varchar(2000) DEFAULT NULL,
`priority` int(2) NOT NULL DEFAULT '0',
`create_time` datetime DEFAULT NULL,
`last_edit_time` datetime DEFAULT NULL,
`parent_id`int(11)  DEFAULT NULL,
primary key(`shop_category_id`),
constraint `fk_shop_category_self` foreign key(`parent_id`) references `tb_shop_category`(`shop_category_id`)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

店鋪

創建Shop.java

package com.one.entity;

import java.util.Date;

public class Shop {
   private Long shopId;
   private String shopName;
   private String shopDesc;
   private String shopAddr;
