一、問題

當(dāng)在gateway的全局過濾器GlobalFilter中注入OpenFeign接口的時(shí)候會(huì)一直卡在路由中，但是不會(huì)進(jìn)一步，導(dǎo)致啟動(dòng)未成功也未報(bào)錯(cuò)失敗

二、原因

在gateway網(wǎng)關(guān)中不能使用openfeign同步調(diào)用

三、解決方法

1、修改配置

	由于配置了spring.cloud.gateway.discovery.locator.enabled = true導(dǎo)致，改為false或者去掉該配置，因?yàn)槟J(rèn)為false，但是該方案會(huì)導(dǎo)致動(dòng)態(tài)路由不能加載，影響微服務(wù)調(diào)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
    @Autowired
    private AuthClient authClient;

全部代碼：?

@Component
@Slf4j
public class GatewayGlobalFilter implements GlobalFilter, Ordered {
    @Autowired
    private AuthProperties authProperties;

    @Lazy
    @Autowired
    private AuthClient authClient;

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        //獲取請(qǐng)求頭的request

        List<String> excludePaths = authProperties.getExcludePaths();
        log.info(excludePaths.toString());
        //判斷是否需要攔截
        ServerHttpRequest request = exchange.getRequest();
        RequestPath path = request.getPath();
        //如果不需要攔截則放行
        if(excludePaths.contains(path.toString())){
            return chain.filter(exchange);
        }
        //獲取token
        String authorization = request.getHeaders()
                .getFirst("authorization");
        String token= authorization.replace("Bearer ","");

        // 驗(yàn)證token
        String userId = authClient.getUserId(token);
        if(userId==null){
            //設(shè)置響應(yīng)碼為401
            ServerHttpResponse response = exchange.getResponse();
            response.setStatusCode(HttpStatus.UNAUTHORIZED);
            return response.setComplete();
        }

        //放行
        return chain.filter(exchange);
    }

    @Override
    public int getOrder() {
        return 0;
    }
}

?3、啟動(dòng)成功
