Effortlessly Manage Spring Boot Config Files with mica-auto

After Spring Boot 2.7 stopped recommending the use of spring.factories, many developers find maintaining multiple configuration files cumbersome.

Open source project: mica-auto

mica-auto is an annotation‑processor‑based library that automatically generates Spring Boot configuration files such as spring.factories, spring-devtools.properties, and, from version 2.3 onward,

org.springframework.boot.autoconfigure.AutoConfiguration.imports

.

How to use mica-auto

Step 1: Add the dependency to pom.xml (use provided scope and place it after Lombok if Lombok is present).

<dependency>
  <groupId>net.dreamlu</groupId>
  <artifactId>mica-auto</artifactId>
  <version>2.3.0</version>
  <scope>provided</scope>
</dependency>

Step 2: Replace old configuration annotations with the newer ones, e.g., use @AutoConfiguration instead of @Configuration, so that the processor generates AutoConfiguration.imports rather than the legacy spring.factories.

@AutoConfiguration
@EnableConfigurationProperties(SwaggerProperties.class)
@ConditionalOnProperty(value = "springfox.documentation.enabled", havingValue = "true", matchIfMissing = true)
@Import({SwaggerUiConfiguration.class, SwaggerAuthorizationConfiguration.class, DocketConfiguration.class})
public class SwaggerAutoConfiguration {
    @Bean
    public DocketBeanFactoryPostProcessor docketBeanFactoryPostProcessor() {
        return new DocketBeanFactoryPostProcessor();
    }
}

After recompiling the project, the appropriate configuration files are generated automatically.
