一、绪论

   JAVA接口返回信息ServerHttpResponse response

等登录接口token过期时需要给前端返回相关状态码和状态信息

二、Mono<Void>向前端返回没有登陆或登录超时 暂无权限访问信息组装

返回Mono对象

public abstract class Mono<T> implements CorePublisher<T>

	/*** 无权限* * @param response* @return*/private Mono<Void> noLogin(ServerHttpResponse response) {log.info("没有登陆或登录超时 暂无权限访问===========");String responseDataStr = JSON.toJSON(ResponseData.error(HttpStatus.UNAUTHORIZED.value(), "The Token has expired")).toString();byte[] bytes = responseDataStr.getBytes(StandardCharsets.UTF_8);DataBuffer buffer = response.bufferFactory().wrap(bytes);response.setStatusCode(HttpStatus.UNAUTHORIZED);return response.writeWith(Mono.just(buffer));}

信息组装。

1、返回ResponseData对象，输出状态码和状态信息：The Token has expired

ResponseData.error(HttpStatus.UNAUTHORIZED.value(), "The Token has expired")

转换成json信息

byte[] bytes = responseDataStr.getBytes(StandardCharsets.UTF_8);

转换成字节流

输出：

response.writeWith(Mono.just(buffer));

公共返回体封装：ResponseData

public class ResponseData<T> implements Serializable {/*** */private static final long serialVersionUID = 7098362967623367826L;/*** 响应状态码*/private Integer code;/*** 响应信息*/private String message;/*** 响应对象*/private T data;/** 是否加密返回参数*/private boolean encrypt;public Integer getCode() {return code;}public void setCode(Integer code) {this.code = code;}public String getMessage() {return message;}public void setMessage(String message) {this.message = message;}public T getData() {return data;}public void setData(T data) {this.data = data;}public static <T> ResponseData<T> success() {return success(ResponseCode.SUCCESS);}public static <T> ResponseData<T> success(ResponseCode code) {return success(code, null);}public static <T> ResponseData<T> success(T object) {return success(ResponseCode.SUCCESS, object);}public static <T> ResponseData<T> success(ResponseCode code, T object) {return success(code.getCode(), code.getMessage(), object);}public static <T> ResponseData<T> success(Integer code, String message, T data) {ResponseData<T> response = new ResponseData<>();response.setCode(code);response.setMessage(message);response.setData(data);return response;}public static <T> ResponseData<T> error() {return error(ResponseCode.FAILED);}public static <T> ResponseData<T> error(ResponseCode code) {return error(code, null);}public static <T> ResponseData<T> error(String message) {return error(ResponseCode.FAILED.getCode(), message, null);}public static <T> ResponseData<T> error(Integer code, String message) {return error(code, message, null);}public static <T> ResponseData<T> error(ResponseCode code, T data) {return error(code.getCode(), code.getMessage(), data);}public static <T> ResponseData<T> error(Integer code, String message, T data) {ResponseData<T> response = new ResponseData<>();response.setCode(code);response.setMessage(message);response.setData(data);return response;}public boolean isEncrypt() {return encrypt;}public void setEncrypt(boolean encrypt) {this.encrypt = encrypt;}
