我想在 DB 上插入一个条目,该条目已填充所有字段,并且与另一个表/类具有 @ManyToOne 关系。为此,我正在调用entityManager.merge(c1),其中 myc1是一个Classification实例(根据下面的定义),我可以在日志中看到以下内容:
[DEBUG] ...: c=o.h.SQL, m=logStatement, l=92, msg: insert into plat.classification_system (year, system, id) values (?, ?, ?)
[TRACE] ...: c=o.h.t.d.s.BasicBinder, m=bind, l=65, msg: binding parameter [1] as [VARCHAR] - [2012]
[TRACE] ...: c=o.h.t.d.s.BasicBinder, m=bind, l=65, msg: binding parameter [2] as [BIGINT] - [1000001]
[TRACE] ...: c=o.h.t.d.s.BasicBinder, m=bind, l=65, msg: binding parameter [3] as [VARCHAR] - [main_system]
......实际上我期待看到类似......
[DEBUG] ...: c=o.h.SQL, m=logStatement, l=92, msg: insert into plat.classification_system (year, system, id, classification_type) values (?, ?, ?, ?)
[TRACE] ...: c=o.h.t.d.s.BasicBinder, m=bind, l=65, msg: binding parameter [1] as [VARCHAR] - [2012]
[TRACE] ...: c=o.h.t.d.s.BasicBinder, m=bind, l=65, msg: binding parameter [2] as [BIGINT] - [1000001]
[TRACE] ...: c=o.h.t.d.s.BasicBinder, m=bind, l=65, msg: binding parameter [3] as [VARCHAR] - [main_system]
[TRACE] ...: c=o.h.t.d.s.BasicBinder, m=bind, l=65, msg: binding parameter [4] as [VARCHAR] - [abc]
...代表以下模型:
create table classification_system (
id number(19, 0) not null,
year varchar2(255 char) not null,
class_type_guid(48 char ) not null,
system varchar2(255 char) not null,
primary key (id)
)
create table class_type (
guid (48 char) not null,
code varchar2(255 char) not null,
year varchar2(255 char) not null,
system_type_guid varchar2(48 char) not null,
primary key (guid)
)
create table system_type (
guid (48 char ) not null,
code varchar2(255 char) not null,
year varchar2(255 char) not null,
primary key (guid)
)
我一直在挖掘很多与@ManyToOne映射/关系相关的帖子,但还没有找到任何我可以使用的东西。这是使用 Hibernate 5.0.9 构建的。
有人可以帮我解决这个问题吗?感谢您对此事的任何帮助。
