         spring-boot-maven-plugin

application.yml

server:  port: 9000management:  endpoints:    web:      exposure:        include: '*'  server:    port: 12345zuul:  routes:    configserver:   #自定义的名字      path: /myConfig/**      serviceId: config    user:      path: /myUser/**      serviceId: provider  ignored-patterns:      - /config/**      - /gateway/**  sensitive-headers:  #ignore-local-service: true  忽略默认的路由

bootstrap.yml

spring:  application:    name: gateway  cloud:    zookeeper:      discovery:        register: true      connect-string: 192.168.3.201:2182    config:      discovery:        service-id: config        enabled: true

启用@EnableZuulProxy

package com.example.apigateway;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.zuul.EnableZuulProxy;@SpringBootApplication@EnableZuulProxypublic class ApiGatewayApplication {    public static void main(String[] args) {        SpringApplication.run(ApiGatewayApplication.class, args);    }}

可以使用：ip:端口/actuator/routes 这样的地址看到已经注册的路由

自定义过滤器:需要继承ZuulFilter

package com.example.apigateway.filter;import com.example.apigateway.util.CookUtil;import com.netflix.zuul.ZuulFilter;import com.netflix.zuul.context.RequestContext;import com.netflix.zuul.exception.ZuulException;import org.apache.commons.lang.StringUtils;import org.springframework.http.HttpStatus;import org.springframework.stereotype.Component;import javax.servlet.http.HttpServletRequest;import static org.springframework.cloud.netflix.zuul.filters.support.FilterConstants.PRE_DECORATION_FILTER_ORDER;import static org.springframework.cloud.netflix.zuul.filters.support.FilterConstants.PRE_TYPE;@Componentpublic class TokenFilter extends ZuulFilter {    @Override    /**     * pre     * post     * route     * error     */    public String filterType() {        return PRE_TYPE;    }    @Override    public int filterOrder() {        return PRE_DECORATION_FILTER_ORDER - 1;    }    @Override    public boolean shouldFilter() {        return true;    }    @Override    public Object run() throws ZuulException {        // 获取请求对象        RequestContext context = RequestContext.getCurrentContext();        HttpServletRequest request = context.getRequest();        // 获取地址栏传入的参数        String token = CookUtil.getCookieValue("token", request).getValue();        if (StringUtils.isEmpty(token)) {            context.setSendZuulResponse(false);            context.setResponseStatusCode(HttpStatus.UNAUTHORIZED.value());        }        return null;    }}
