一、緒論

? ?JAVA接口返回信息ServerHttpResponse response

等登錄接口token過(guò)期時(shí)需要給前端返回相關(guān)狀態(tài)碼和狀態(tài)信息

二、Mono<Void>向前端返回沒(méi)有登陸或登錄超時(shí) 暫無(wú)權(quán)限訪(fǎng)問(wèn)信息組裝

返回Mono對(duì)象

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

	/*** 無(wú)權(quán)限* * @param response* @return*/private Mono<Void> noLogin(ServerHttpResponse response) {log.info("沒(méi)有登陸或登錄超時(shí) 暫無(wú)權(quán)限訪(fǎng)問(wèn)===========");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));}

信息組裝。

1、返回ResponseData對(duì)象，輸出狀態(tài)碼和狀態(tài)信息：The Token has expired

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

轉(zhuǎn)換成json信息

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

轉(zhuǎn)換成字節(jié)流

輸出：

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

公共返回體封裝：ResponseData
