1.DAO层之新增店铺
首先在dao层添加ShopDao接口
public interface ShopDao {
/**
* 新增店铺
* @param shop
* @return
*/
int insertShop(Shop shop);
}
在src/main/resources/mapper下添加ShopDao.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.yorisk.o2o.dao.ShopDao">
<insert id="insertShop" useGeneratedKeys="true"
keyColumn="shop_id" keyProperty="shopId">
INSERT INTO
tb_shop(owner_id,area_id,shop_category_id,shop_name,shop_desc,shop_addr,
phone,shop_img,priority,create_time,last_edit_time,enable_status,advice)
VALUES
(#{owner.userId},#{area.areaId},#{shopCategory.shopCategoryId},#{shopName},
#{shopDesc},#{shopAddr},#{phone},#{shopImg},#{priority},#{createTime},
#{lastEditTime},#{enableStatus},#{advice})
</insert>
</mapper>在src/test/java下的dao包中添加ShopDaoTest
public class ShopDaoTest extends BaseTest{
@Autowired
private ShopDao shopDao;
@Test
public void testInsertShop() {
Shop shop = new Shop();
PersonInfo owner = new PersonInfo();
Area area = new Area();
ShopCategory shopCategory = new ShopCategory();
owner.setUserId(1L);
area.setAreaId(2);
shopCategory.setShopCategoryId(1L);
shop.setOwner(owner);
shop.setArea(area);
shop.setShopCategory(shopCategory);
shop.setShopName("测试店铺");
shop.setShopDesc("test");
shop.setShopAddr("test");
shop.setPhone("test");
shop.setShopImg("test");
shop.setCreateTime(new Date());
shop.setEnableStatus(1);
shop.setAdvice("审核中");
int effectedNum = shopDao.insertShop(shop);
assertEquals(1,effectedNum);
}
}运行junit，会发现下图
添加成功。
2.DAO层之更新店铺
首先在dao层的ShopDao接口里添加更新店铺的方法
/**
* 更新店铺
* @param shop
* @return
*/
int updateShop(Shop shop);在对应的mapper文件ShopDap.xml添加
<update id="updateShop" parameterType="com.yorisk.o2o.dao.ShopDao">
update tb_shop
<set>
<if test="shopName!=null">shop_name=#{shopName},</if>
<if test="shopDesc!=null">shop_desc=#{shopDesc},</if>
<if test="shopAddr!=null">shop_addr=#{shopAddr},</if>
<if test="phone!=null">phone=#{phone},</if>
<if test="shopImg!=null">shop_img=#{shopImg},</if>
<if test="priority!=null">priority=#{priority},</if>
<if test="lastEditTime!=null">last_edit_time=#{lastEditTime},</if>
<if test="enableStatus!=null">enable_status=#{enableStatus},</if>
<if test="advice!=null">advice=#{advice},</if>
<if test="area!=null">area_id=#{area.areaId},</if>
<if test="shopCategory!=null">shop_category_id=#{shopCategory.shopCategoryId}</if>
</set>
where shop_id=#{shopId}
</update>其中使用了动态更新。
在ShopDaoTest中添加测试更新的方法
@Test
public void testUpdateShop() {
Shop shop = new Shop();
shop.setShopId(1L);
shop.setShopDesc("测试描述");
shop.setShopAddr("测试地址");
shop.setLastEditTime(new Date());
int effectedNum = shopDao.updateShop(shop);
assertEquals(1,effectedNum);
}为了不执行前面的添加店铺方法，可以在前面加上@Ignore注解
更新成功。
3.Thumbnailator图片处理封装Util
导入依赖
<dependency>
<groupId>net.coobird</groupId>
<artifactId>thumbnailator</artifactId>
<version>0.4.8</version>
</dependency>如果之前导过了就不需要再导了。
创建util包，创建ImageUtil
public class ImageUtil {
private static String basePath = Thread.currentThread().getContextClassLoader().getResource("").getPath();
public static void main(String[] args) throws IOException {
Thumbnails.of(new File("E:/o2o/littleYellowbaby.jpg")).size(200, 200)
.watermark(Positions.BOTTOM_RIGHT, ImageIO.read(new File(basePath + "/watermark.jpg")), 0.5f)
.outputQuality(0.8f).toFile("E:/o2o/littleYellowbabynew.jpg");
}
}
创建PathUtil类
public class PathUtil {
private static String seperator = System.getProperty("file.separator");
public static String getImgBasePath() {
String os = System.getProperty("os.name");
String basePath = "";
if(os.toLowerCase().startsWith("win")) {
basePath = "E:/o2o/image/";
}else {
basePath = "/home/xiangzai/image/";
}
basePath = basePath.replace("/", seperator);
return basePath;
}
public static String getShopImagePath(long shopId) {
String imagePath = "/upload/item/shop/"+shopId+"/";
return imagePath.replace("/", seperator);
}
}运行imageUtil，可以发现在E:/o2o/下多了加了水印的图片
4.DTO之ShopExecution的实现
在DTO下创建ShopExecution，需要自己添加对应的set，get方法
public class ShopExecution {
// 结果状态
private int state;
// 状态标识
private String stateInfo;
// 店铺数量
private int count;
// 操作的shop(增删改店铺的时候用到)
private Shop shop;
// shop列表(查询店铺列表的时候使用)
private List<Shop> shopList;
public ShopExecution() {
}
// 店铺操作失败的时候使用的构造器
public ShopExecution(ShopStateEnum stateEnum) {
this.state = stateEnum.getState();
this.stateInfo = stateEnum.getStateInfo();
}
// 店铺操作成功的时候使用的构造器
public ShopExecution(ShopStateEnum stateEnum, Shop shop) {
this.state = stateEnum.getState();
this.stateInfo = stateEnum.getStateInfo();
this.shop = shop;
}
// 店铺操作成功的时候使用的构造器
public ShopExecution(ShopStateEnum stateEnum, List<Shop> shopList) {
this.state = stateEnum.getState();
this.stateInfo = stateEnum.getStateInfo();
this.shopList = shopList;
}在enums包下创建ShopStateEnum
public enum ShopStateEnum {
CHECK(0, "审核中"), OFFLINE(-1, "非法店铺"), SUCCESS(1, "操作成功"), PASS(2, "通过认证"), INNER_ERROR(-1001, "内部系统错误"),
NULL_SHOPID(-1002, "ShopId为空");
private int state;
private String stateInfo;
private ShopStateEnum(int state, String stateInfo) {
this.state = state;
this.stateInfo = stateInfo;
}
public int getState() {
return state;
}
public String getStateInfo() {
return stateInfo;
}
/**
* 依据传入的state返回响应的enum值
* @param state
* @return
*/
public static ShopStateEnum stateOf(int state) {
for(ShopStateEnum stateEnum : values()) {
if(stateEnum.getState() == state) {
return stateEnum;
}
}
return null;
}
}
由于我们不希望别人来修改我们的状态码和内容，所以对我们的构造函数进行私有化，并且不提供set方法
