JPA activity. Activity의 Property는 다음과 같습니다.
- store : @Repository가 붙은 컴포넌트
- repository : org.springframework.data.repository.Repository 를 extends 한 컴포넌트
- method : store나 repository에 해당하는 컴포넌트의 method 이름
- param-count : method의 parameter 수
- param# : key::type 형태. type 누락시 java.lang.String 으로 함.
- result-key : Activity의 수행 결과에 대한 key 값
