自定义环境仓库

Spring Cloud 配置支持通过创建和集成自定义的环境仓库实现来增强配置管理。这使得您的应用程序能够添加独特的配置源。实现 Ordered 接口并指定 getOrder 方法还能让你在复合配置设置中设置自定义仓库的优先级。没有这个功能，自定义仓库默认会被视为最低优先级。spring-doc.cadn.net.cn

以下是如何创建和配置自定义的示例环境仓库:spring-doc.cadn.net.cn

public class CustomConfigurationRepository implements EnvironmentRepository, Ordered {

    @Override
    public Environment findOne(String application, String profile, String label) {
        // Simulate fetching configuration from a custom source
        final Map<String, String> properties = Map.of(
            "key1", "value1",
            "key2", "value2",
            "key3", "value3"
        );
        Environment environment = new Environment(application, profile);
        environment.add(new PropertySource("customPropertySource", properties));
        return environment;
    }

    @Override
    public int getOrder() {
        return 0;
    }
}

@Configuration
@Profile("custom")
public class AppConfig {
    @Bean
    public CustomConfigurationRepository customConfigurationRepository() {
        return new CustomConfigurationRepository();
    }
}

按照这个设置，如果你激活了习惯配置文件在你的Spring应用配置中，你的自定义环境仓库将集成到配置服务器中。例如，指定习惯你的档案application.properties或application.yml如下：spring-doc.cadn.net.cn

spring:
  application:
    name: configserver
  profiles:
    active: custom

现在，访问配置服务器：spring-doc.cadn.net.cn

http://localhost:8080/any-client/dev/latest

将返回自定义仓库的默认值，如下所示：spring-doc.cadn.net.cn

{
  "name": "any-client",
  "profiles": ["dev"],
  "label": "latest",
  "propertySources": [
    {
      "name": "customPropertySource",
      "source": {
        "key1": "value1",
        "key2": "value2",
        "key3": "value3"
      }
    }
  ]
}
