Spring 启动 JPA 查询返回 null 值，但在普通 PSQL 中工作

Question

在我的JpaRepository<User, Long>我有以下查询

  @Query(
      nativeQuery = true,
      value =
          "SELECT SUM(CAST(u.foo->'foo'->>'points' AS INTEGER)) AS totalActivePoints "
              + "FROM blah.user u "
              + "WHERE u.user_id = :userId "
              + "AND (u.end_date IS NULL OR u.end_date > now()) "
              + "GROUP BY u.user_id ")
  Integer getPointSum(long userId);

我基本上只是想从作为user表的一部分的jsonb类型foo中获取 integer points的总和。 出于某种原因，此方法不断返回 null 值，即使数据确实存在并且我可以看到它在这里工作得很好。

db 表如下所示：

CREATE TABLE IF NOT EXISTS foo
    (
        type                    TEXT            NOT NULL    PRIMARY KEY,
        points                  INTEGER         NOT NULL,
        ...
    );

CREATE TABLE IF NOT EXISTS user
(
    id                  BIGSERIAL       NOT NULL    PRIMARY KEY,
    user_id             BIGINT          NOT NULL,
    start_date          TIMESTAMP       DEFAULT NULL,
    end_date            TIMESTAMP       DEFAULT NULL,

    foo                 JSONB           NOT NULL
);

实体：

@Setter
@Getter
@NoArgsConstructor
@EqualsAndHashCode
@Entity
@Table(name = "user")
@TypeDef(name = "jsonb", typeClass = JsonBinaryType.class)
public class User implements Serializable {

  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  private long id;

  private long userId;
  private Date startDate;
  private Date endDate;

  @Type(type = "jsonb")
  @Column(columnDefinition = "jsonb")
  private Foo foo;
}

@Setter
@Getter
@NoArgsConstructor
@EqualsAndHashCode
@Entity
@Table(name = "foo")
public class Foo implements Serializable {

  @Id
  @Column(name = "type")
  @Enumerated(EnumType.STRING)
  private Type type;

  private int points;
 ...
}

样本表数据，如 json，存在：

{
  "id" : 1,
  "userId" : 1234,
  "startDate" : 1656668960145,
  "endDate" : 1657273760146,
  "foo" : {
    "type" : "BOTS",
    "points" : 23
    }
  }
}

{
  "id" : 2,
  "userId" : 1234,
  "startDate" : 1656668960204,
  "endDate" : 1657878560146,
  "foo" : {
    "type" : "TRIGGERBOT",
    "points" : 14
    }
  }
}

此外，返回List<Object>而不是获取总和 ALSO 还会返回一个包含 null 值的列表......我到底在做什么错？

如果重要，请使用 PSQL 14、Spring Boot 2.4.5 和 JDK 11。

编辑：将 select 更改为：

"select sum( CAST (jsonb_extract_path_text(u.foo, 'foo', 'points') AS INTEGER )) AS totalActivePoints "

也不会改变任何东西。
