4-4 Dto之ShopExecution实现

在添加店铺Service层编写之前，要先编写添加店铺的返回类型

存储在Dto中

记录添加店铺成功或失败的状态

 public class ShopExecution { 	/** 	 * 状态 为枚举类型，在ShopStateEnum.java中定义 	 */ 	//结果状态 	private int state; 	//状态标识(以文字的形式解释state的作用) 	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() { 		 	} 	//在店铺操作失败时使用的构造器--生成ShopExecution对象 	public ShopExecution(ShopStateEnum stateEnum) { 		this.state = stateEnum.getState(); 		this.stateInfo = stateEnum.getStateInfo(); 	} 	//在店铺操作在成功时使用的构造器-返回一个店铺对象 	public ShopExecution(ShopStateEnum stateEnum,Shop shop) { 		this.state = stateEnum.getState(); 		this.stateInfo = stateEnum.getStateInfo(); 	} 	//在店铺操作在成功时使用的构造器-返回一个店铺对象列表 	public ShopExecution(ShopStateEnum stateEnum,List<Shop> shopList) { 		this.state = stateEnum.getState(); 		this.stateInfo = stateEnum.getStateInfo(); 		this.shopList = shopList; 	} 	public int getState() { 		return state; 	} 	public void setState(int state) { 		this.state = state; 	} 	public String getStateInfo() { 		return stateInfo; 	} 	public void setStateInfo(String stateInfo) { 		this.stateInfo = stateInfo; 	} 	public int getCount() { 		return count; 	} 	public void setCount(int count) { 		this.count = count; 	} 	public Shop getShop() { 		return shop; 	} 	public void setShop(Shop shop) { 		this.shop = shop; 	} 	public List<Shop> getShopList() { 		return shopList; 	} 	public void setShopList(List<Shop> shopList) { 		this.shopList = shopList; 	} 	 } 

枚举类型在ShopStateEnum类中定义

 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"),NULL_SHOP(-1003,"shop信息为空"); 	private int state; 	private String stateInfo;  	// 创建构造器，是私有的原因：不希望外部能够改变枚举的值，即把它们当做常量 	private ShopStateEnum(int state, String stateInfo) { 		this.state = state; 		this.stateInfo = stateInfo; 	}  	/** 	 * 依据传入的state返回响应的enum值 	 */ 	public static ShopStateEnum stateOf(int state) { 		for (ShopStateEnum stateEnum : values()) { 			if (stateEnum.getState() == state) { 				return stateEnum; 			} 		} 		return null; 	}  	public int getState() { 		return state; 	}  	public String getStateInfo() { 		return stateInfo; 	} }
