一、问题

当在gateway的全局过滤器GlobalFilter中注入OpenFeign接口的时候会一直卡在路由中，但是不会进一步，导致启动未成功也未报错失败

二、原因

在gateway网关中不能使用openfeign同步调用

三、解决方法

1、修改配置

	由于配置了spring.cloud.gateway.discovery.locator.enabled = true导致，改为false或者去掉该配置，因为默认为false，但是该方案会导致动态路由不能加载，影响微服务调用。gateway:discovery:locator:enabled: false 

2、添加@Lazy注解在client上面

在注入的AuthClient上面添加@Lazy注解

    @Lazy@Autowiredprivate AuthClient authClient;

全部代码： 

@Component
@Slf4j
public class GatewayGlobalFilter implements GlobalFilter, Ordered {@Autowiredprivate AuthProperties authProperties;@Lazy@Autowiredprivate AuthClient authClient;@Overridepublic Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {//获取请求头的requestList<String> excludePaths = authProperties.getExcludePaths();log.info(excludePaths.toString());//判断是否需要拦截ServerHttpRequest request = exchange.getRequest();RequestPath path = request.getPath();//如果不需要拦截则放行if(excludePaths.contains(path.toString())){return chain.filter(exchange);}//获取tokenString authorization = request.getHeaders().getFirst("authorization");String token= authorization.replace("Bearer ","");// 验证tokenString userId = authClient.getUserId(token);if(userId==null){//设置响应码为401ServerHttpResponse response = exchange.getResponse();response.setStatusCode(HttpStatus.UNAUTHORIZED);return response.setComplete();}//放行return chain.filter(exchange);}@Overridepublic int getOrder() {return 0;}
}
