QueryDSL Sorting

Pageable의 Sort필드를 그대로 사용하는 방법으로 정렬을 하는게 가장 적합하고, 요청 쿼리 파라미터에는 sort=regDt,asc와 같은 형식으로 주어지면 Pageable의 Sort에서 받아진다.

import com.querydsl.core.types.Order;
import com.querydsl.core.types.OrderSpecifier;
import com.querydsl.core.types.Path;
import com.querydsl.core.types.dsl.Expressions;

public class QueryDslUtil {

    public static OrderSpecifier<?> getSortedColumn(Order order, Path<?> parent, String fieldName) {
        Path<Object> fieldPath = Expressions.path(Object.class, parent, fieldName);
        return new OrderSpecifier(order, fieldPath);
    }
}
