Spring Boot에서 Ehcache 사용하기

Spring에서 로컬 캐시가 필요한 경우 Ehcache를 사용하면 편리하다.

 

dependencies {
	implementation('org.springframework.boot:spring-boot-starter-cache')
	
	implementation group: 'javax.cache', name: 'cache-api', version: '1.1.1'
	implementation group: 'org.ehcache', name: 'ehcache', version: '3.8.1'
}

import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableCaching
public class EhcacheConfig {

}

spring:
