EntityRepository 

public interface EntityRepository<T, ID extends Serializable> {
        .       
        .       
        public List<T> findAll(Object query);
        public List<T> findAll(Object query, Sort sort);
        public Page<T> findAll(Object query, Pageable pageable);
        
        public long count(Object query);
}
Note:
EntityRepository 의 count() 및 findAll() 의 인자를 springfield 에서는 Entity Query Object 라고 명명 하고, 이 객체를 통해 검색을 위한 where 조건 및 order 항목이 동적으로 결정된다.

FindByIdAndPasswordAndNameAndAddress ( Entity Query Object )

package example.u2ware.springfield.part1;

import lombok.Getter;
import lombok.Setter;

public class FindByIdAndPasswordAndNameAndAddress {

        public @Getter @Setter Integer id;
        public @Getter @Setter String password;
        public @Getter @Setter String address;
        public @Getter @Setter String name;     
}

SampleQuery ( Entity Query Object )

package example.u2ware.springfield.part1;

import com.u2ware.springfield.repository.QueryMethod;

import lombok.Getter;
import lombok.Setter;

@QueryMethod("findByIdAndPasswordAndNameAndAddress")
public class SampleQuery {

        public @Getter @Setter Integer id;
        public @Getter @Setter String password;
        public @Getter @Setter String address;
        public @Getter @Setter String name;
}

Note:
EntityRepository 는 Entity Query Object 의 Class 이름 이나 선언된 @com.u2ware.springfield.repository.QueryMethod 속성 값에 따라 QueryMethod을 결정한다.

SQLSESSION 전략에서 QueryMethod는 sqlsession.xml 에 미리정의된 mapping query statement 를 의미한다.

JPA 전략에서 QueryMethod는 "findBy~" 로 시작하는 spring-data JPA Query Method 을 따른다.

MONGODB 전략에서 QueryMethod는 "findBy~" 로 시작하는 spring-data mongodb Query Method 을 따른다.
