spring jpa 针对复合主键如何通过 @Query 查询？

    @Query("select count(id) from UserRecommendedEntity where id.userId = :userId and isLike = :isLike")
    int countByUserIdAndIsLike(Long userId, int isLike);

上面代码ide会提示无法解析的字段 id.userId。我的 UserRecommendedEntity 代码如下：

@Data
@Accessors(chain = true)
@Entity
@Table(name = "user_recommended")
public class UserRecommendedEntity {

    @EmbeddedId
    private UnionId id;

    @Column(name = "is_like")
    private Integer isLike;

    @Column(name = "created_at")
    private String createdAt;

    @Data
    public static class UnionId implements Serializable {
        @Column(name = "user_id")
        private Long userId;

        @Column(name = "recommended_user_id")
        private Long recommendedUserId;
    }
}
