Spring boot stater development tool mica-auto 2.0.3 released

1. Introduction

mica-auto (Spring boot stater development tool) is a basic component in Spring cloud microservice framework Mica, used to generate some basic configurations of Spring boot starter.

2. Function

1. Generate spring.factories.
2. Generate spring-devtools.properties
3. Generate FeignClient into spring.factories for Feign automatic configuration in mica-cloud.
4. To generate java Spi configuration, you need to add @AutoService annotation.

annotation	spring.factories 或 Spi key
@AutoContextInitializer	ApplicationContextInitializer
@AutoListener	ApplicationListener
@AutoRunListener	SpringApplicationRunListener
@AutoEnvPostProcessor	EnvironmentPostProcessor
@AutoFailureAnalyzer	FailureAnalyzer
@AutoConfigImportFilter	AutoConfigurationImportFilter
@AutoTemplateProvider	TemplateAvailabilityProvider
@AutoEnableCircuitBreaker	EnableCircuitBreaker
@AutoConfigDataLocationResolver	ConfigDataLocationResolver
@AutoConfigDataLoader	ConfigDataLoader
@Component	EnableAutoConfiguration
@AutoIgnore	Ignore, do not generate to spring.factories
@AutoService	java Spi generation configuration

Three, change records

Add AutoConfigDataLocationResolver.
Add AutoConfigDataLoader

Four, use

Note: If you use Lombok in your project, please place the dependency of mica-auto behind Lombok.

4.1 maven

<dependency>
  <groupId>net.dreamlu</groupId>
  <artifactId>mica-auto</artifactId>
  <version>2.0.3</version>
  <scope>provided</scope>
</dependency>

4.2 gradle >= 5.x

annotationProcessor("net.dreamlu:mica-auto:2.0.3")

4.3 gradle < 5.x

compileOnly "net.dreamlu:mica-auto:2.0.3"

4.4 java spi example:

Add the annotation @AutoService to specify the Processor.class of the spi interface.

package foo.bar;

import javax.annotation.processing.Processor;

@AutoService(Processor.class)  
public class MyProcessor implements Processor {
// …
}

AutoService will automatically generate spi configuration file META-INF/services/javax.annotation.processing.Processor. content:

foo . bar . MyProcessor

Five, usage scenarios

Spring boot starter is a powerful tool for development, which automatically generates spring.factories and spring-devtools.properties configuration.
The sub-projects in the multi-module project are automatically configured when the package names are different (the main project is not recommended to add).
The java spi extension automatically generates the configuration.

It is recommended to pay attention to Rumeng Technology Code Cloud: https://gitee.com/596392912 , more microservice core components are worth having.
