Boost Spring Boot Development with mica-auto: Auto-Generate Starter Configurations

1. Introduction

mica-auto (Spring Boot starter tool) is used to generate Spring Boot starter configuration files. It employs an Annotation Processor to scan @Component at compile time, automatically creating the appropriate configuration and supporting composite annotations. mica-auto is widely used in the mica, mica-mqtt, pig, and SpringBlade ecosystems.

2. Features

Generate spring.factories.

Support Spring Boot 2.7.x new AutoConfiguration annotation, generating entries in the new AutoConfiguration.imports configuration.

Generate spring-devtools.properties.

Generate Java SPI configuration, requiring the @AutoService annotation.

3. Update Log

✨ Support Kotlin meta‑annotation (GitHub #8), thanks to @Sunrise66 for feedback.

Version info:

Version 3.1.2 – Spring Boot 3.x – Java 17

Version 2.3.3 – Spring Boot 1.x ~ 3.x – Java 1.8

Note: mica-auto does not enforce a Spring Boot dependency; it only bundles spring-boot-configuration-processor for convenience.

4. Usage

Note:

If your project uses Lombok, place the mica-auto dependency after Lombok.

Maven

<dependency>
  <groupId>net.dreamlu</groupId>
  <artifactId>mica-auto</artifactId>
  <version>${mica-auto.version}</version>
  <scope>provided</scope>
</dependency>

Gradle >= 5.x

annotationProcessor("net.dreamlu:mica-auto:$micaAutoVersion}")

Gradle < 5.x

compileOnly "net.dreamlu:mica-auto:$micaAutoVersion"

5. Effect

Using mica-auto to automatically generate Spring Boot starter configurations frees your hands and prevents missing or incorrect configurations that could cause service startup failures. Give it a try!
