小编aj1*_*984的帖子

我有以下设置，其中我的 Eureka 服务器正在运行，并且在 Eureka 中创建和注册的服务很少正在运行。所有服务呼叫的服务都在使用已负载平衡的休息模板进行，并且一切正常。

现在，我已经使用以下代码/属性将基于 Zuul 的路由引入到应用程序中 -

@SpringBootApplication
@EnableZuulProxy
public class ApiGatewayApplication {

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

    @Bean
     public CorsFilter corsFilter() {
         final UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource= new UrlBasedCorsConfigurationSource();
         final CorsConfiguration corsConfig = new CorsConfiguration();
         corsConfig.setAllowCredentials(true);
         corsConfig.addAllowedOrigin("*");
         corsConfig.addAllowedHeader("*");
         corsConfig.addAllowedMethod("OPTIONS");
         corsConfig.addAllowedMethod("HEAD");
         corsConfig.addAllowedMethod("GET");
         corsConfig.addAllowedMethod("PUT");
         corsConfig.addAllowedMethod("POST");
         corsConfig.addAllowedMethod("DELETE");
         corsConfig.addAllowedMethod("PATCH");
         urlBasedCorsConfigurationSource.registerCorsConfiguration("/**", corsConfig);
         return new CorsFilter(urlBasedCorsConfigurationSource);
     }
}

有了这个，我的路由工作得非常好，但是现在有一个服务需要接近 12 秒的执行时间，而且我的业务要求禁止打入较小的调用。

这会导致 Zuul 中的超时异常。

下面是我的 .yml 文件 -

ribbon:
  ConnectTimeout: 60000
  ReadTimeout: 600000
zuul:
  host:
    socket-timeout-millis: 60000
hystrix:
    command:
        default:
            execution: …

我对Spring Cloud和Spring外部配置的概念很陌生,实际上是昨天开始的.

我创建了一个Config Server从本地Git存储库中挑选配置,一个微服务也是配置客户端和一个Eureka驱动的服务发现服务器.

以下是我主要从互联网上的各种资源中借用的代码 -

配置服务器 - application.yml:

server:
  port: 8888

spring:
  cloud:
    config:
      server:
        git:
          uri: file:///${user.home}/config-repo

配置服务器 - 主类(引导程序)

@EnableConfigServer
@SpringBootApplication
public class CloudConfigServerApplication {

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

config-repo是我机器上的本地git repo,并且有一个.yml文件,其名称为config client application,即authmanager.yml

eureka:
    client:
        serviceUrl:
            defaultZone: http://127.0.0.1:8761/eureka/
        healthcheck:
            enabled: true
        lease:
            duration: 5
spring:
    application:
        data:   
            mongodb:
                host: localhost
                port: 27017
                database: edc_mc
logging:
    level:
        org.exampledriven.eureka.customer.shared.CustomerServiceFeignClient: FULL

现在运行配置服务器后,下面是端点http:// localhost:8888/authmanager/default的输出 -

{"name":"authmanager","profiles":["default"],"label":"master","version":"0ca6ca7b4502b9bb6ce1bf8efeb25516682cf79a","propertySources":[{"name":"file:///C:\\Users\\username/config-repo/authmanager.yml","source":{"eureka.client.serviceUrl.defaultZone":"http://127.0.0.1:8761/eureka/","eureka.client.healthcheck.enabled":true,"eureka.client.lease.duration":5,"spring.application.data.mongodb.host":"localhost","spring.application.data.mongodb.port":27017,"spring.application.data.mongodb.database":"db_name","logging.level.org.exampledriven.eureka.customer.shared.CustomerServiceFeignClient":"FULL"}}]}

微服务+配置客户端代码 -

bootstrap.yml -

server:
  port: 9097

spring: …

我对 Spring boot 有点陌生，下面是我的应用程序的 POM/Java 文件：
