Spring Boot Repository Native Query for DTO in Postgresql Issue
问题
我在使用Spring Boot和PostgreSQL时编写DTO的本地查询时遇到了问题。
以下是DTO的定义：
@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserCommentsResponse {
private String placeName;
private String text;
}
以下是本地查询的定义：
@Query(value="SELECT new com.demo.project.dao.UserCommentsResponse(placeName, text) FROM comment c inner join place p on p.id = c.place_id where customer_id = :id", nativeQuery=true)
List<UserCommentsResponse> getUsersComments(int id);
以下是错误消息：
org.postgresql.util.PSQLException: ERROR: syntax error at or near "."
我该如何修复这个问题？

尝试这个
@Query(value="SELECT UserCommentsResponse(placeName, text) FROM comment c inner join place p on p.id = c.place_id where customer_id = :id", nativeQuery=true)
而不是您原始的查询。
英文:
Try this
@Query(value="SELECT UserCommentsResponse(placeName, text) FROM comment c inner join place p on p.id = c.place_id where customer_id = :id", nativeQuery=true)
instead of your original query
