Usage

1. Add the JitPack repository to your build file

gradle

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

maven

<positories>
	<repository>
		<id>jitpack.io</id>
		<url>https://jitpack.io</url>
	</repository>
</repositories>

2. Add the dependency

gradle

dependencies {
    implementation 'com.github.Dev-Beom:KWarmUp:Tag'
}

maven

<dependency>
	<groupId>com.github.Dev-Beom</groupId>
	<artifactId>KWarmUp</artifactId>
    <version>Tag</version>
</dependency>

3. Add EnableKWarmUp Annotation to @Component

@EnableKWarmUp
@Configuration
class SomeConfiguration

4. Write KWarmUp annotation on the target (method) to be warmed up.

However, the class of the target method must be @Component. (Annotations that inherit and use this are also possible. @Service, @Repository, @Configuration...)

@Service
class SomeService {
    @KWarmUp(repeatCount = 256)
    fun callMailService() {
    }
}
