    zuul启动项

    @SpringBootApplication
    @EnableZuulProxy
    @EnableEurekaClient
    public class ServerZuulApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ServerZuulApplication.class, args);
        }
    }
    
    

    参数配置

    
    eureka.client.serviceUrl.defaultZone=http://localhost:8888/eureka/
    
    server.port=8763
    
    spring.application.name=service-zuul
    
    zuul.routes.api-a.path=/member/**
    
    zuul.routes.api-a.service-id=service-order
    
    zuul.routes.api-b.path=/provide/**
    
    zuul.routes.api-b.service-id=service-provide
    
    zuul.routes.api-c.path=/client/**
    
    zuul.routes.api-c.service-id=config-client
    
    
    

    ps:api-c 这个是自己写的 service-id = 值 千万别写错!!!

    filter

    
    package com.boolib.cloud.server_zuul.filter;

    import javax.servlet.http.HttpServletRequest;
    import java.io.IOException;
    
    @Component
    @Slf4j
    public class MyFilter extends ZuulFilter {
    
    
    
        @Override
        public String filterType() {
            return "pre";
        }
    
        @Override
        public int filterOrder() {
            return 0;
        }
    
        @Override

            return true;
        }
    
        @Override
        public Object run() throws ZuulException {
    
            RequestContext ctx = RequestContext.getCurrentContext();
    
            HttpServletRequest request = ctx.getRequest();
    
            Object token = request.getParameter("token");
    
            if(token!=null)
            {
                return null;
            }
    
            ctx.setSendZuulResponse(false);
            ctx.setResponseStatusCode(401);
    
            try {
                ctx.getResponse().getWriter().write("token is empty");
            }
            catch(IOException ex)
            {
    
            }
            return null;
        }
    }
