自定义环境存储库
Spring Cloud Config 通过允许您创建和集成自定义 EnvironmentRepository 实现来支持增强其配置管理。这样就可以向应用程序添加唯一的配置源。通过实现 Ordered 接口并指定 getOrder 方法,您还可以在复合配置设置中设置自定义存储库的优先级。否则,默认情况下,自定义存储库的优先级最低。
以下是如何创建和配置自定义的示例 :EnvironmentRepository
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();
}
}
通过此设置,如果您在 Spring 应用程序的配置中激活配置文件,则您的自定义环境存储库将集成到配置服务器中。例如,在 or 中指定配置文件,如下所示:custom
custom
application.properties
application.yml
spring:
application:
name: configserver
profiles:
active: custom
现在,访问配置服务器:
http://localhost:8080/any-client/dev/latest
将返回自定义仓库中的默认值,如下所示:
{
"name": "any-client",
"profiles": ["dev"],
"label": "latest",
"propertySources": [
{
"name": "customPropertySource",
"source": {
"key1": "value1",
"key2": "value2",
"key3": "value3"
}
}
]
}
