使用Spring Cloud Config和Discovery无法获取logback-spring.xml属性文件 [英] Unable to get logback-spring.xml property file using Spring Cloud Config and Discovery

问题描述

我正在使用

I'm using Discovery first bootstrap feature and Consul as a Discovery Server, url to Config Server is located during start-up and I was able to get application.properties. I need also to get logback-spring.xml configuration from Config server and I don't know how.

我应该在logging.config={???}logback-spring.xml属性中指定什么，以免将url硬编码到Config Server?

What should I specify in logging.config={???}logback-spring.xml property to not hardcode url to Config Server?

在Consul集成之前，我使用的是根据

Before Consul integration I was using url formed according to Serving Plain text documentation with hardcoded Config server url in properties and it was working fine, but now we want to avoid this.

根据我的调试，在PropertySourceBootstrapConfiguration中重新初始化日志记录系统期间没有使用Discovery客户端.

From what I debugged there is no usage of Discovery client during reinitializing logging system in PropertySourceBootstrapConfiguration.

推荐答案

我使用了

I used Customizing Bootstrap Configuration to resolve my issue in a 'custom' way because I didn't find the solution in the documentation and source code.

示例:添加新文件src/main/resources/META-INF/spring.factories并在其中添加自定义引导程序配置:org.springframework.cloud.bootstrap.BootstrapConfiguration=sample.custom.CustomPropertySourceLocator

Example: Add new file src/main/resources/META-INF/spring.factories and add there custom bootstrap configuration: org.springframework.cloud.bootstrap.BootstrapConfiguration=sample.custom.CustomPropertySourceLocator

在CustomPropertySourceLocator中，创建指向配置服务器URL(通过发现查找)的属性

In CustomPropertySourceLocator create property that will point to config server url (looked up via discovery)

@Configuration
public class CustomPropertySourceLocator implements PropertySourceLocator {

  private final String configServiceName;
  private final DiscoveryClient discoveryClient;

  public CustomPropertySourceLocator(
      @Value("${spring.cloud.config.discovery.service-id}") String configServiceName,
      DiscoveryClient discoveryClient){
    this.configServiceName = configServiceName;
    this.discoveryClient = discoveryClient;
  }

  @Override
  public PropertySource<?> locate(Environment environment) {
    List<ServiceInstance> instances = this.discoveryClient.getInstances(this.configServiceName);
    ServiceInstance serviceInstance = instances.get(0);

    return new MapPropertySource("customProperty",
      Collections.singletonMap("configserver.discovered.uri", serviceInstance.getUri()));
  }
}

在上面的代码中，我们创建了具有一个属性configserver.discovered.uri的自定义属性源.我们可以在代码中(使用@Value)或其他属性文件(即使它们位于配置服务器存储中)使用此属性.

In code above we created custom property source that will have one property configserver.discovered.uri. We can use this property in our code (using @Value) or in other property files (even if they are located in the config-server storage).

logging.config=${configserver.discovered.uri}/<path to the text file>/logback-spring.xml 应根据提供纯文本文档<path to text file> >以及配置服务器的方式.

logging.config=${configserver.discovered.uri}/<path to the text file>/logback-spring.xml where <path to text file> should be formed according to the Serving Plain Text Documentation and the way how you configured your config-server.
