2.常量

（1）精品页常量类

public class CategoryConstant {public static Map<Integer,String> categorys;static {categorys = new HashMap<>();categorys.put(1100, "东方玄幻");categorys.put(1200, "都市小说");categorys.put(1300, "西方玄幻");categorys.put(1400, "武侠仙侠");categorys.put(1500, "历史穿越");categorys.put(1600, "科幻未来");categorys.put(1700, "网游竞技");categorys.put(1800, "悬疑惊悚");categorys.put(2100, "古代言情");categorys.put(2200, "幻想言情");categorys.put(2300, "都市言情");categorys.put(2400, "总裁豪门");categorys.put(2500, "青春校园");categorys.put(2600, "唯美同人");categorys.put(2700, "历史穿越");categorys.put(2800, "唯美同人");categorys.put(3100, "文学小说");categorys.put(3200, "经典名著");}
}

（2）jwt常量类

public class JwtConstant {/** JWT秘钥 */public final static String SECRET_KEY = "someday";/** 过期时间天数 */public final static int EXPIRE_DAY = 7;}

3.图书相关枚举

（1）图书分类枚举类

public enum BookCategoryEnum {CATEGORY_1(1,"都市小说"),CATEGORY_2(2,"东方玄幻"),CATEGORY_3(3,"武侠仙侠"),CATEGORY_4(4,"悬疑惊悚"),CATEGORY_5(5,"唯美同人"),CATEGORY_6(6,"网游竞技"),CATEGORY_7(7,"科幻未来"),CATEGORY_8(8,"历史穿越");private Integer value;private String name;BookCategoryEnum(Integer value, String name) {this.value = value;this.name = name;}public Integer getValue() {return value;}public String getName() {return name;}
}

（2）书单列表功能枚举类

public enum BooklistMoreTypeEnum {NOTHING(1,"无"),MORE(2,"更多"),EXCHANGE(3,"换一换"),LOADING(4,"加载");private int value;private String name;BooklistMoreTypeEnum(int value, String name) {this.value = value;this.name = name;}public int getValue() {return value;}public String getName() {return name;}
}

（3）图书连载状态枚举类

public enum BookSerialStatusEnum {SERIAL(1,"连载"),SUSPEND(2,"暂更"),END(3,"完结");private Integer value;private String name;BookSerialStatusEnum(Integer value, String name) {this.value = value;this.name = name;}public Integer getValue() {return value;}public String getName() {return name;}
}

4.请求参数封装

public class RequestParams extends HashMap {private static final Logger LOGGER = LoggerFactory.getLogger(RequestParams.class);/*** 获取整型参数值* @param paramName* @return*/public Integer getIntValue(String paramName){Integer value = 0;Object object = this.get(paramName);if (null == object) {return value;}try{value = Integer.parseInt(this.get(paramName).toString());} catch (Exception ex){value = 0;LOGGER.error("获取参数{}转换整型异常！{}", paramName, ex);}return value;}/*** 获取字符串参数值* @param paramName* @return*/public String getStringValue(String paramName){String value = "";Object object = this.get(paramName);if (null == object) {return value;}return object.toString();}
}

5.统一返回结果

（1）Http状态码封装

/*** * http 状态码* ----------------------------------------------------------------------------* 200 OK - [GET]：服务器成功返回用户请求的数据，该操作是幂等的（Idempotent）。* 400 INVALID REQUEST - [POST/PUT/PATCH]：用户发出的请求有错误，服务器没有进行新建或修改数据的操作，该操作是幂等的。* 401 Unauthorized - [*]：表示用户没有权限（令牌、用户名、密码错误）。* 403 Forbidden - [*] 表示用户得到授权（与401错误相对），但是访问是被禁止的。* 404 NOT FOUND - [*]：用户发出的请求针对的是不存在的记录，服务器没有进行操作，该操作是幂等的。* 406 Not Acceptable - [GET]：用户请求的格式不可得（比如用户请求JSON格式，但是只有XML格式）。* 410 Gone -[GET]：用户请求的资源被永久删除，且不会再得到的。* 422 Unprocesable entity - [POST/PUT/PATCH] 当创建一个对象时，发生一个验证错误。* 500 INTERNAL SERVER ERROR - [*]：服务器发生错误，用户将无法判断发出的请求是否成功。* 600 UN_KNOW_ERROR - 未知错误* ----------------------------------------------------------------------------*/
public enum HttpCodeEnum {OK(200,"操作成功"),INVALID_REQUEST(400,"参数错误"),UNAUTHORIZED(401,"没有权限"),FORBIDDEN(403,"禁止访问"),NOT_FOUND(404,"资源不存在"),NOT_ACCEPTABLE(406,"请求的格式不正确"),GONE(410,"数据被删除"),UNPROCESABLE_ENTITY(422,"参数验证错误"),INTERNAL_SERVER_ERROR(500,"服务器发生错误"),UN_KNOW_ERROR(500,"未知错误"),FAIL(501,"操作失败"),MODEL_NOT_EXIST(1000, "模型不存在"),VERIFICATION_FAILED(1001, "业务逻辑验证未通过"),USERNAME_OR_PASSWORD_ERR(2000,"用户未登录或token已失效"),DELETE_DEFAULT_PHOTO_ERR(2001,"默认头像不可删除"),AUTH_EXPIRED(3000,"认证到期"),TOKEN_ERR(3001, "token无效");private final int code;private final String message;HttpCodeEnum(final int code, final String message){this.code=code;this.message=message;}public String getMessage() {return message;}public int getCode() {return code;}}

（2）操作结果封装

public class Result<T>  implements Serializable {private static final long serialVersionUID = 1L;private int code;private String msg;private T data;public Result(int code, String msg, T data) {this.code = code;this.msg = msg;this.data = data;}public Result(int code, String msg) {this.code = code;this.msg = msg;}public Result() {}/*** 构建消息内容* @param msg* @return*/public Result buildMessage(String msg){this.setMsg(msg);return this;}/*** 构建消息data的值，key默认为data* @param obj data值* @return*/public Result buildData(T obj){this.setData(obj);return this;}public int getCode() {return code;}public void setCode(int code) {this.code = code;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public T getData() {return data;}public void setData(T data) {this.data = data;}
}

（3）返回结果工具类

ResultUtil {/*** 请求成功* @return*/public static Result success() {return new Result(HttpCodeEnum.OK.getCode(),HttpCodeEnum.OK.getMessage());}/*** 请求成功（无消息）* @return*/public static Result successAndNoMsg() {return new Result(HttpCodeEnum.OK.getCode(),"");}/*** 成功请求** @param data* @return*/public static Result success(Object data) {return new Result(HttpCodeEnum.OK.getCode(), HttpCodeEnum.OK.getMessage() , data);}/*** 成功请求（无消息）** @param data* @return*/public static Result successAndNoMsg(Object data) {return new Result(HttpCodeEnum.OK.getCode(), "", data);}/*** 操作失败* @return*/public static Result fail() {return new Result(HttpCodeEnum.FAIL.getCode(), HttpCodeEnum.FAIL.getMessage());}/*** 操作失败* @return*/public static Result fail(Object data) {return new Result(HttpCodeEnum.FAIL.getCode(), HttpCodeEnum.FAIL.getMessage() ,data);}/*** 服务器错误* @return*/public static Result error() {return new Result(HttpCodeEnum.INTERNAL_SERVER_ERROR.getCode(),HttpCodeEnum.INTERNAL_SERVER_ERROR.getMessage());}/*** 服务器错误* @param data* @return*/public static Result error(Object data) {return new Result(HttpCodeEnum.INTERNAL_SERVER_ERROR.getCode(),HttpCodeEnum.INTERNAL_SERVER_ERROR.getMessage(), data);}/*** 参数错误* @return*/public static Result paramError() {return new Result(HttpCodeEnum.INVALID_REQUEST.getCode(), HttpCodeEnum.INVALID_REQUEST.getMessage());}/*** 参数错误* @param data* @return*/public static Result paramError(Object data) {return new Result(HttpCodeEnum.INVALID_REQUEST.getCode(), HttpCodeEnum.INVALID_REQUEST.getMessage(), data);}/*** 认证到期* @return*/public static Result authExpired() {return new Result(HttpCodeEnum.AUTH_EXPIRED.getCode(), HttpCodeEnum.AUTH_EXPIRED.getMessage());}/*** 没有权限* @return*/public static Result unAuthorized() {return new Result(HttpCodeEnum.UNAUTHORIZED.getCode(), HttpCodeEnum.UNAUTHORIZED.getMessage());}/*** 没有权限* @param data* @return*/public static Result unAuthorized(Object data) {return new Result(HttpCodeEnum.UNAUTHORIZED.getCode(),HttpCodeEnum.UNAUTHORIZED.getMessage(),data);}/***  禁止访问* @return*/public static Result forbidden() {return new Result(HttpCodeEnum.FORBIDDEN.getCode(),HttpCodeEnum.FORBIDDEN.getMessage());}/*** 禁止访问* @param data* @return*/public static Result forbidden(Object data) {return new Result(HttpCodeEnum.FORBIDDEN.getCode(),HttpCodeEnum.FORBIDDEN.getMessage(), data);}/*** 资源不存在* @return*/public static Result notFound() {return new Result(HttpCodeEnum.NOT_FOUND.getCode(),HttpCodeEnum.NOT_FOUND.getMessage());}/*** 资源不存在* @param data* @return*/public static Result notFound(Object data) {return new Result(HttpCodeEnum.NOT_FOUND.getCode(),HttpCodeEnum.NOT_FOUND.getMessage(), data);}/*** 请求的格式不正确* @return*/public static Result notAcceptable() {return new Result(HttpCodeEnum.NOT_ACCEPTABLE.getCode(),HttpCodeEnum.NOT_ACCEPTABLE.getMessage());}/*** 请求的格式不正确* @param data* @return*/public static Result notAcceptable(Object data) {return new Result(HttpCodeEnum.NOT_ACCEPTABLE.getCode(),HttpCodeEnum.NOT_ACCEPTABLE.getMessage(), data);}/*** 数据已经被删除* @return*/public static Result gone() {return new Result(HttpCodeEnum.GONE.getCode(),HttpCodeEnum.GONE.getMessage());}/*** 数据已经被删除* @param data* @return*/public static Result gone(Object data) {return new Result(HttpCodeEnum.GONE.getCode(),HttpCodeEnum.GONE.getMessage(), data);}/*** 实体参数校验错误* @return*/public static Result unprocesableEntity() {return new Result(HttpCodeEnum.UNPROCESABLE_ENTITY.getCode(),HttpCodeEnum.UNPROCESABLE_ENTITY.getMessage());}/*** 实体参数校验错误* @param data* @return*/public static Result unprocesableEntity(Object data) {return new Result(HttpCodeEnum.UNPROCESABLE_ENTITY.getCode(),HttpCodeEnum.UNPROCESABLE_ENTITY.getMessage(), data);}/*** 未知错误* @return*/public static Result unKnowError() {return new Result(HttpCodeEnum.UN_KNOW_ERROR.getCode(),HttpCodeEnum.UN_KNOW_ERROR.getMessage());}/*** 未知错误* @param data* @return*/public static Result unKnowError(Object data) {return new Result(HttpCodeEnum.UN_KNOW_ERROR.getCode(),HttpCodeEnum.UN_KNOW_ERROR.getMessage(), data);}/*** 业务逻辑验证未通过* @return*/public static Result verificationFailed() {return new Result(HttpCodeEnum.VERIFICATION_FAILED.getCode(),HttpCodeEnum.VERIFICATION_FAILED.getMessage());}/*** 业务逻辑验证未通过* @param data* @return*/public static Result verificationFailed(Object data) {return new Result(HttpCodeEnum.VERIFICATION_FAILED.getCode(),HttpCodeEnum.VERIFICATION_FAILED.getMessage(), data);}/*** 自定义返回* @param e* @return*/public static Result custom(HttpCodeEnum e) {return new Result(e.getCode(),e.getMessage());}/*** 自定义返回* @param error* @return*/public static Result custom(int code,String error) {return new Result(code,error);}/*** 自定义返回* @param error* @param data* @return*/public static Result custom(int code,String error,Object data) {return new Result(code,error,data);}}
