在本地主机上工作的 zuul 无法识别到通过 Eureka 连接的其他微服务的路由

如何解决在本地主机上工作的 zuul 无法识别到通过 Eureka 连接的其他微服务的路由

你好开发人员我正在使用微服务架构在这个应用程序中工作，但是由于某种原因，当我通过 zuul API 网关运行应用程序时，服务 id 及其路径无法被 zuul 处理程序识别，从而在我的 Postman 上抛出错误，例如 

endpoint: method GET: http://localhost:9001/micro/service/zuul/product/all/products
{
    "timestamp": "2021-02-28T11:11:45.770+00:00","status": 404,"error": "Not Found","message": "No message available","path": "/micro/service/zuul/product/all/products"
}

当我通过 zuul 微服务检查我的 IDE 控制台时，行为会像

我的zuul应用是这样设计的：

package com.microzuul;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@EnableEurekaClient
@EnableZuulProxy
@SpringBootApplication
public class MicrozuulApplication {

    public static void main(String[] args) {
        SpringApplication.run(MicrozuulApplication.class,args);
    }

}

还有它

参考它的应用程序属性，其中在所有微服务和路径中声明以通过其设计将是这样的：

spring.application.name=micro-zuul
server.port=9001

eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka
eureka.client.fetch-registry=true

management.endpoints.web.exposure.include=*
management.endpoint.routes.enabled=true
management.endpoint.filters.enabled=true

zuul.routes.productsService.service-id=micro-products
zuul.routes.productsService.path=/micro/service/zuul/product/**
zuul.routes.productsService.strip-prefix=false

zuul.routes.oauth2Service.service-id=micro-oauth2
zuul.routes.oauth2Service.path=/micro/service/zuul/security/**
zuul.routes.oauth2Service.sensitive-headers=Cookie,Set-Cookie

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds:60000
ribbon.ConnectTimeout:9000
ribbon.ReadTimeout:30000


spring.sleuth.sampler.probability=1.0


spring.zipkin.base-url=http://localhost:9411
RabitMQ como gestor de trazas de zipkin
#spring.zipkin.sender.type=rabbit

所有的流程都在 Eureka Server 中解决，因此 Eureka 配置了 app 属性和 pom 就这样解决了：


spring.application.name=micro-eureka-server

server.port=8761

eureka.client.register-with-eureka=false
eureka.client.fetch=false

然后最后但并非最不重要的 woukd 是我的微服务之一，用于此示例“微产品” 应用道具会以这种方式结算的地方：

spring.application.name=micro-products
server.port=${PORT:0}
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${random.value}}
spring.datasource.url=jdbc:mysql://localhost:3306/xxxxxxxxxxxxxxxxxxxxxxx?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.datasource.username=xxxxxxxxxxx
spring.datasource.password=xxxxxxxx
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
logging.level.org.hibernate.SQL=debug
eureka.client.service-url.defaultZone=http://localhost:8761/eureka
spring.main.allow-bean-definition-overriding=true
spring.sleuth.sampler.probability=1.0
spring.zipkin.base-url=http://localhost:9411
spring.zipkin.sender.type=rabbit
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds:60000
ribbon.ConnectTimeout:9000
ribbon.ReadTimeout:30000

为了不扩展问题，我确认控制器端点已经被检查并且完全相同，并且在安全配置中引用路由的权限与 permitAll() 相同并通过 permitAll() 保证
