Question

我要外部配置文件使用spring-boot应用程序。我保存在Amazon S3中的配置文件。如何编写代码以在项目中加载配置？谢谢

这里https://github.com/spring-cloud/spring-cloud-config/issues/654处有一个开放的请求，要求将S3用作Spring Cloud Config的后端存储。 https://github.com/mwnorman/spring-cloud-config-server-s3

尝试通过样板代码来实现此目的

在此处复制相关部分

它取决于spring-cloud-config-server和aws-java-sdk-s3并具有 META-INF / spring.factories中的自动配置类： org.springframework.boot.autoconfigure.EnableAutoConfiguration = \ org.springframework.cloud.config.s3.CloudConfigS3AutoConfiguration 看起来像

@Configuration
@ConditionalOnBean(CloudConfigS3Configuration.Marker.class)
@EnableConfigurationProperties(CloudConfigS3Properties.class)
@Import({S3EnvironmentRepositoryConfiguration.class})
public class CloudConfigS3AutoConfiguration {}

S3EnvironmentRepositoryConfiguration类看起来像

@Configuration
public class S3EnvironmentRepositoryConfiguration {
    @Autowired
    protected ConfigurableEnvironment environment;
    @Autowired
    protected CloudConfigS3Properties s3Properties;
    @Bean
    @Primary
    public EnvironmentRepository environmentRepository() {
        return new S3EnvironmentRepository(environment, s3Properties);
    }
    @Bean
    public CloudConfigS3Properties buildCloudConfigS3Properties() {
        return new CloudConfigS3Properties();
    }
}

一个简单的客户端：

@SpringBootApplication(
    //Hmm I think I shouldn't have to do this ... haven't figured it out yet
    exclude = {
        org.springframework.cloud.config.server.config.ConfigServerAutoConfiguration.class
    }
)
@EnableS3CloudConfig
public class Client {

    public static void main(String[] args) {
        ConfigurableApplicationContext applicationContext = new SpringApplicationBuilder(Client.class)
            .web(false)
            .run(args)
        ;
        applicationContext.getEnvironment().getProperty("foo.bar");
    }
}
