如何通过zuul代理从一个微服务访问另一个微服务

Question

我正在开发使用spring启动的微服务项目。在这里，UI页面在独立的微服务和独立的微服务中的zuul代理中。我想通过zuul微服务访问UI页面。我在下面添加了我的项目结构。

UiService Application.properties：

server.port=8090 
spring.mvc.view.prefix: /WEB-INF/views/ 
spring.mvc.view.suffix: .jsp 
spring.application.name=ui 
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/ 
eureka.instance.preferIpAddress=true 
eureka.instance.leaseRenewalIntervalInSeconds=5 

zuulService application.yml：

server: 
port: 8080 
eureka: 
instance: 
    leaseRenewalIntervalInSeconds: 10 
    statusPageUrlPath: /info 
    healthCheckUrlPath: /health  

logging: 
level: 
    ROOT: INFO 
    org.springframework.web: DEBUG 
zuul: 
    routes: 
    ui: 
     url: http://localhost:8090 
ribbon: 
    eager-load: 
    enabled: false 

我的搬运工撰写文件：

version: '3' 
services: 
    eureka: 
    build: eurekaService 
    ports: 
     - "8761:8761" 
    zuul: 
    build: zuulService 
    links: 
    - eureka 
    ports: 
     - "8080:8080" 
    turbine: 
    build: turbineService 
    links: 
    - eureka 
    ports: 
    - "8989:8989" 
    ui: 
    build: uiService 
    links: 
    - eureka 
    ports: 
    - "8090:8090" 

uiSer副结构：

我尤里卡服务页面：

运行这个项目在泊坞窗（码头工人，组成了-d）之后，当我试图访问登录屏幕（在uiService中可用）获得以下异常。如何解决这个问题？

UIService主要方法：

@SpringBootApplication 
@EnableDiscoveryClient 
@EnableCircuitBreaker 
public class UIApplication { 

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

uiService的pom.xml：

Answer 1

localhost:8090/login是直接请求到UI应用程序，没有Zuul参与。

如果没有加载/显示页面，则可能是启动应用程序时出错，或者/login不存在。

你介意分享日志吗？
