1、Result 工具类
依赖：工具类依赖lombok，HttpStatusEnum 两个类，如果想自定义状态码可以修改HttpStatusEnum.java为自己的状态码和注释
import lombok.Data; /** * @author zhanghuiwen * http返回值 */ @Data public class Result<T> { public Result(boolean success, int code) { this.setSuccess(success); this.setCode(code); } public Result(boolean success, int code, T data) { this.setSuccess(success); this.setCode(code); this.setData(data); } public Result(boolean success, int code, String msg) { this.setSuccess(success); this.setCode(code); this.setData(data); } /** * 请求是否成功 * true:成功 * false：失败 */ private boolean success; /** * 状态码 * 成功：200 * 失败：其他 */ private int code; /** * 失败状态码描述 * 如果成功不返回 * 失败返回状态码对应的msg消息 */ private String msg; /** * 请求数据的结果 */ private T data; public static <T> Result<T> success() { return new Result<T>(true, 200); } public static <T> Result<T> success(T data) { return new Result<T>(true, 200, data); } public static <T> Result<T> fail(HttpStatusEnum httpStatusEnum) { return new Result<T>(false, httpStatusEnum.code(), httpStatusEnum.reasonPhraseUS()); } public static <T> Result<T> fail(HttpStatusEnum httpStatusEnum, String msg) { return new Result<T>(false, httpStatusEnum.code(), msg); } }
2、HttpStatusEnum 枚举了所有http状态码
/** * http所有状态码枚举 */ public enum HttpStatusEnum { /** * http状态码枚举所有状态码注解 */ CONTINUE(100, "Continue", "请继续发送请求的剩余部分"), SWITCHING_PROTOCOLS(101, "Switching Protocols", "协议切换"), PROCESSING(102, "Processing", "请求将继续执行"), CHECKPOINT(103, "Checkpoint", "可以预加载"), OK(200, "OK", "请求已经成功处理"), CREATED(201, "Created", "请求已经成功处理，并创建了资源"), ACCEPTED(202, "Accepted", "请求已经接受，等待执行"), NON_AUTHORITATIVE_INFORMATION(203, "Non-Authoritative Information", "请求已经成功处理，但是信息不是原始的"), NO_CONTENT(204, "No Content", "请求已经成功处理，没有内容需要返回"), RESET_CONTENT(205, "Reset Content", "请求已经成功处理，请重置视图"), PARTIAL_CONTENT(206, "Partial Content", "部分Get请求已经成功处理"), MULTI_STATUS(207, "Multi-Status", "请求已经成功处理，将返回XML消息体"), ALREADY_REPORTED(208, "Already Reported", "请求已经成功处理，一个DAV的绑定成员被前一个请求枚举，并且没有被再一次包括"), IM_USED(226, "IM Used", "请求已经成功处理，将响应一个或者多个实例"), MULTIPLE_CHOICES(300, "Multiple Choices", "提供可供选择的回馈"), MOVED_PERMANENTLY(301, "Moved Permanently", "请求的资源已经永久转移"), FOUND(302, "Found", "请重新发送请求"), // MOVED_TEMPORARILY(302, "Moved Temporarily", "") 已经过时 SEE_OTHER(303, "See Other", "请以Get方式请求另一个URI"), NOT_MODIFIED(304, "Not Modified", "资源未改变"), USE_PROXY(305, "Use Proxy", "请通过Location域中的代理进行访问"), // 306在新版本的规范中被弃用 TEMPORARY_REDIRECT(307, "Temporary Redirect", "请求的资源临时从不同的URI响应请求"), RESUME_INCOMPLETE(308, "Resume Incomplete", "请求的资源已经永久转移"), BAD_REQUEST(400, "Bad Request", "请求错误，请修正请求"), UNAUTHORIZED(401, "Unauthorized", "没有被授权或者授权已经失效"), PAYMENT_REQUIRED(402, "Payment Required", "预留状态"), FORBIDDEN(403, "Forbidden", "请求被理解，但是拒绝执行"), NOT_FOUND(404, "Not Found", "资源未找到"), METHOD_NOT_ALLOWED(405, "Method Not Allowed", "请求方法不允许被执行"), NOT_ACCEPTABLE(406, "Not Acceptable", "请求的资源不满足请求者要求"), PROXY_AUTHENTICATION_REQUIRED(407, "Proxy Authentication Required", "请通过代理进行身份验证"), REQUEST_TIMEOUT(408, "Request Timeout", "请求超时"), CONFLICT(409, "Conflict", "请求冲突"), GONE(410, "Gone", "请求的资源不可用"), LENGTH_REQUIRED(411, "Length Required", "Content-Length未定义"), PRECONDITION_FAILED(412, "Precondition Failed", "不满足请求的先决条件"), REQUEST_ENTITY_TOO_LARGE(413, "Request Entity Too Large", "请求发送的实体太大"), REQUEST_URI_TOO_LONG(414, "Request-URI Too Long", "请求的URI超长"), UNSUPPORTED_MEDIA_TYPE(415, "Unsupported Media Type", "请求发送的实体类型不受支持"), REQUESTED_RANGE_NOT_SATISFIABLE(416, "Requested range not satisfiable", "Range指定的范围与当前资源可用范围不一致"), EXPECTATION_FAILED(417, "Expectation Failed", "请求头Expect中指定的预期内容无法被服务器满足"), // I_AM_A_TEAPOT(418, "I'm a teapot", ""), 该代码没有被服务器实现 // INSUFFICIENT_SPACE_ON_RESOURCE(419, "Insufficient Space On Resource", ""), 已经过时 // METHOD_FAILURE(420, "Method Failure", ""), 已经过时 // DESTINATION_LOCKED(421, "Destination Locked", ""), 已经过时 UNPROCESSABLE_ENTITY(422, "Unprocessable Entity", "请求格式正确，但是由于含有语义错误，无法响应"), LOCKED(423, "Locked", "当前资源被锁定"), FAILED_DEPENDENCY(424, "Failed Dependency", "由于之前的请求发生错误，导致当前请求失败"), UPGRADE_REQUIRED(426, "Upgrade Required", "客户端需要切换到TLS1.0"), PRECONDITION_REQUIRED(428, "Precondition Required", "请求需要提供前置条件"), TOO_MANY_REQUESTS(429, "Too Many Requests", "请求过多"), REQUEST_HEADER_FIELDS_TOO_LARGE(431, "Request Header Fields Too Large", "请求头超大，拒绝请求"), INTERNAL_SERVER_ERROR(500, "Internal Server Error", "服务器内部错误"), NOT_IMPLEMENTED(501, "Not Implemented", "服务器不支持当前请求的部分功能"), BAD_GATEWAY(502, "Bad Gateway", "响应无效"), SERVICE_UNAVAILABLE(503, "Service Unavailable", "服务器维护或者过载，拒绝服务"), GATEWAY_TIMEOUT(504, "Gateway Timeout", "上游服务器超时"), HTTP_VERSION_NOT_SUPPORTED(505, "HTTP Version not supported", "不支持的HTTP版本"), VARIANT_ALSO_NEGOTIATES(506, "Variant Also Negotiates", "服务器内部配置错误"), INSUFFICIENT_STORAGE(507, "Insufficient Storage", "服务器无法完成存储请求所需的内容"), LOOP_DETECTED(508, "Loop Detected", "服务器处理请求时发现死循环"), BANDWIDTH_LIMIT_EXCEEDED(509, "Bandwidth Limit Exceeded", "服务器达到带宽限制"), NOT_EXTENDED(510, "Not Extended", "获取资源所需的策略没有被满足"), NETWORK_AUTHENTICATION_REQUIRED(511, "Network Authentication Required", "需要进行网络授权"); private final int code; private final String reasonPhraseUS; private final String reasonPhraseCN; private static final int INFORMATIONAL = 1, SUCCESSFUL = 2, REDIRECTION = 3, CLIENT_ERROR = 4, SERVER_ERROR = 5; HttpStatusEnum(int code, String reasonPhraseUS, String reasonPhraseCN) { this.code = code; this.reasonPhraseUS = reasonPhraseUS; this.reasonPhraseCN = reasonPhraseCN; } public int code() { return code; } public String reasonPhraseUS() { return reasonPhraseUS; } public String reasonPhraseCN() { return reasonPhraseCN; } public static HttpStatusEnum valueOf(int code) { for (HttpStatusEnum httpStatus : values()) { if (httpStatus.code() == code) { return httpStatus; } } throw new IllegalArgumentException("No matching constant for [" + code + "]"); } public boolean is1xxInformational() { return type() == INFORMATIONAL; } public boolean is2xxSuccessful() { return type() == SUCCESSFUL; } public boolean is3xxRedirection() { return type() == REDIRECTION; } public boolean is4xxClientError() { return type() == CLIENT_ERROR; } public boolean is5xxServerError() { return type() == SERVER_ERROR; } private int type() { return (int) code / 100; } }
