spring自动注入组件方式

    @Configuration
    @ComponentScan("package")
    public class TestConfig {
    }

    @Retention(RetentionPolicy.RUNTIME)
    @Target({ElementType.TYPE})
    @Documented
    @Import({TestConfig.class})
    public @interface EnableTestConfig {
    }

    @EnableLogRecordClient
    @Configuration
    public class Test {
    }

3.spring 主动发现方式：

    resources/META_INF/spring.factories 文件 

    org.springframework.boot.autoconfigure.EnableAutoConfiguration=     package.class
