Spring boot SseEmitter 推送数据客户端乱码

• 继承 SseEmitter 重写extendResponse，请求头事件流指定utf-8编码

public class SseEmitterUTF8 extends SseEmitter {public SseEmitterUTF8(Long timeout) {super(timeout);}@Overrideprotected void extendResponse(ServerHttpResponse outputMessage) {super.extendResponse(outputMessage);HttpHeaders headers = outputMessage.getHeaders();headers.setContentType(new MediaType(MediaType.TEXT_EVENT_STREAM, StandardCharsets.UTF_8));}
}
