Question

我正在使用spring boot开发微服务项目。这里，UI页面位于单独的微服务中的独立微服务和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

我的码头撰写文件：

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"

ui服务结构：

我的尤里卡服务页面：

在docker（docker-compose up -d）中运行此项目后，当我尝试访问登录屏幕（uiService内部可用）时，会出现以下异常。怎么解决这个问题？

UIService主要方法：

@SpringBootApplication
@EnableDiscoveryClient
@EnableCircuitBreaker
public class UIApplication {

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

uiService pom.xml：

Answer 1

localhost:8090/login是对UI应用的直接请求，不涉及Zuul。

如果它没有加载/显示页面，则在启动应用程序或/login不存在时可能会出错。

你介意分享日志吗？
