背景

须要对spingActuator的监测门路进行拦挡，从而实现弹窗输出登录信息的性能，然而gateway提供的GlobalFilter拦截器不失效，故钻研了一番

解决形式

应用WebFilter进行拦挡，拦截器代码如下：

import org.springframework.core.annotation.Order;import org.springframework.http.HttpHeaders;import org.springframework.http.HttpStatus;import org.springframework.http.server.reactive.ServerHttpRequest;import org.springframework.http.server.reactive.ServerHttpResponse;import org.springframework.stereotype.Component;import org.springframework.web.server.ServerWebExchange;import org.springframework.web.server.WebFilter;import org.springframework.web.server.WebFilterChain;import reactor.core.publisher.Mono;import sun.misc.BASE64Decoder;import java.io.IOException;import java.util.Objects;@Order(2)@Componentpublic class ActuatorFilter implements WebFilter {    @Override    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {        ServerHttpRequest request = exchange.getRequest();        ServerHttpResponse response = exchange.getResponse();        String uriPath = request.getURI().getPath();        if(uriPath.startsWith("/actuator/")) {            String auth = request.getHeaders().getFirst(HttpHeaders.AUTHORIZATION);            if(Objects.isNull(auth)){                System.out.println("校验申请头为空，需进行登录..");                response.getHeaders().add(HttpHeaders.WWW_AUTHENTICATE,"Basic realm="."");                response.setStatusCode(HttpStatus.UNAUTHORIZED);                return response.setComplete();            }else {                System.out.println("auth:" + auth);                BASE64Decoder decoder = new BASE64Decoder();                String[] values = new String[0];                try {                    values = new String(decoder.decodeBuffer(auth.split(" ")[1])).split(":");                } catch (IOException e) {                    throw new RuntimeException(e);                }                if (values.length == 2) {                    String username = values[0];                    String pwd = values[1];                    System.out.println("username:" + username);                    System.out.println("pwd:" + pwd);                    if(Objects.equals("test",username) && Objects.equals("test",pwd)){                        return chain.filter(exchange);                    }else {                        response.getHeaders().add(HttpHeaders.WWW_AUTHENTICATE,"Basic realm="."");                        response.setStatusCode(HttpStatus.UNAUTHORIZED);                        return response.setComplete();                    }                }            }        }        return chain.filter(exchange);    }}
