带有 Panache 的 Quarkus Hibernate 将意外 ID 列添加到 Select 查询
Quarkus Hibernate with Panache adds Unexpected ID column to Select Query
这是我第一次尝试使用带 Panache 的 Hibernate。我正在研究一个无服务器函数来插入和更新数据库中的记录。但在此之前，我需要从 table 获得一个 ID。此 ID 将在每条记录进入数据库时添加到它。
数据库是 DB2 AS/400 table 并且定义如下：
CREATE TABLE PCFPIDS (
IDSCOMP CHAR(2) NOT NULL DEFAULT '' ,
IDSID NUMERIC(11, 0) NOT NULL DEFAULT 0 ,
IDSMAX NUMERIC(11, 0) NOT NULL DEFAULT 0 )
PRIMARY KEY( IDSCOMP ) );
我的实体 class 定义为：
@Entity
public class PCFPIDS extends PanacheEntity {
public String IDSCOMP;
public String IDSID;
public int IDSMAX;
public static PCFPIDS getLatestSession() {
return find("IDSCOMP", "##").firstResult();
}
}
然而，当我 运行 应用程序时，我收到以下错误：

我正在记录休眠 SQL 语句，这是它的输出：
Hibernate:

from
PCFPIDS pcfpids0_
where
pcfpids0_.IDSCOMP=? fetch first 1 rows only
出于某种原因 Hibernate/Panache 正在添加 pcfpids0_.id as id1_0_,。然而，如果我用 @Id 注释字段 IDSCOMP 然后我得到这个错误：

我不确定如何解决这个问题。我无法更改 AS/400 DB2 table 并添加 ID 列。那么如何告诉 Hibernate/Panache 不要将此 Id 列添加到我的 select 查询中？
当我们的实体 extends PanacheEntity 时，我们从 PanacheEntity 继承了 Long id。
如果我们想使用非Long id，我们的实体应该extends PanacheBaseEntity。然后必须用 @Id:
注释主键字段
@Entity
public class PCFPIDS extends PanacheEntityBase {
public String IDSCOMP;
public String IDSID;
@Id
public int IDSMAX;
public static PCFPIDS getLatestSession() {
return find("IDSCOMP", "##").firstResult();
}
}
有关如何使用 hibernate panache 的更多信息，我建议阅读 official quarkus guide on hibernate panache。
代码备注：
在java中，class名称应写在CamelCase，字段名称应写在camelCase中（IDSIP -> idsId).我们可以通过将注释 @Table(name = "<tableNameGoesHere>") 和 @Column(name = "<columnNameGoesHere>") 分别添加到 classes 和字段来使 class- 和字段名称与数据库模式对齐。
这是我第一次尝试使用带 Panache 的 Hibernate。我正在研究一个无服务器函数来插入和更新数据库中的记录。但在此之前，我需要从 table 获得一个 ID。此 ID 将在每条记录进入数据库时添加到它。
数据库是 DB2 AS/400 table 并且定义如下：
CREATE TABLE PCFPIDS (
IDSCOMP CHAR(2) NOT NULL DEFAULT '' ,
IDSID NUMERIC(11, 0) NOT NULL DEFAULT 0 ,
IDSMAX NUMERIC(11, 0) NOT NULL DEFAULT 0 )
PRIMARY KEY( IDSCOMP ) );
我的实体 class 定义为：
@Entity
public class PCFPIDS extends PanacheEntity {
public String IDSCOMP;
public String IDSID;
public int IDSMAX;
public static PCFPIDS getLatestSession() {
return find("IDSCOMP", "##").firstResult();
}
}

我不确定如何解决这个问题。我无法更改 AS/400 DB2 table 并添加 ID 列。那么如何告诉 Hibernate/Panache 不要将此 Id 列添加到我的 select 查询中？
当我们的实体 extends PanacheEntity 时，我们从 PanacheEntity 继承了 Long id。
如果我们想使用非Long id，我们的实体应该extends PanacheBaseEntity。然后必须用 @Id:
@Entity
public class PCFPIDS extends PanacheEntityBase {
public String IDSCOMP;
public String IDSID;
@Id
public int IDSMAX;
public static PCFPIDS getLatestSession() {
return find("IDSCOMP", "##").firstResult();
}
}
有关如何使用 hibernate panache 的更多信息，我建议阅读 official quarkus guide on hibernate panache。
代码备注：
在java中，class名称应写在CamelCase，字段名称应写在camelCase中（IDSIP -> idsId).我们可以通过将注释 @Table(name = "<tableNameGoesHere>") 和 @Column(name = "<columnNameGoesHere>") 分别添加到 classes 和字段来使 class- 和字段名称与数据库模式对齐。
