hibernate高手请进,exception setting property value with CGLIB 问题

[yangyijieyyj]

表间关系如下:
-- Create table
create table T_TOPIC_APPLIED
(
BOOTHS INTEGER,
SPACE NUMBER(5,1),
TOPICID NUMBER(10) not null,
TOPICAPPLIEDID NUMBER(10) not null,
USERID NUMBER(10) not null,
EXPOID NUMBER(10) not null
)
tablespace EXPO
pctfree 10
initrans 1
maxtrans 255
storage
(
initial 64K
minextents 1
maxextents unlimited
);
-- Create/Recreate primary, unique and foreign key constraints
alter table T_TOPIC_APPLIED
add primary key (TOPICAPPLIEDID)
using index
tablespace EXPO
pctfree 10
initrans 2
maxtrans 255
storage
(
initial 64K
minextents 1
maxextents unlimited
);
alter table T_TOPIC_APPLIED
add constraint FK_TOPIC_APPLIED_1 foreign key (EXPOID)
references T_EXPO (EXPOID) on delete cascade;
alter table T_TOPIC_APPLIED
add foreign key (TOPICID)
references T_EXPO_TOPIC (TOPICID) on delete cascade;
alter table T_TOPIC_APPLIED
add foreign key (USERID)
references T_USER (USERID) on delete cascade;


-- Create table
create table T_TOPIC_ITEM_APPLIED
(
ITEMAPPLIEDID NUMBER(10) not null,
ITEMID NUMBER(10) not null,
TOPICAPPLIEDID NUMBER(10) not null
)
tablespace EXPO
pctfree 10
initrans 1
maxtrans 255
storage
(
initial 64K
minextents 1
maxextents unlimited
);
-- Create/Recreate primary, unique and foreign key constraints
alter table T_TOPIC_ITEM_APPLIED
add primary key (ITEMAPPLIEDID)
using index
tablespace EXPO
pctfree 10
initrans 2
maxtrans 255
storage
(
initial 64K
minextents 1
maxextents unlimited
);
alter table T_TOPIC_ITEM_APPLIED
add foreign key (TOPICAPPLIEDID)
references T_TOPIC_APPLIED (TOPICAPPLIEDID) on delete cascade;
alter table T_TOPIC_ITEM_APPLIED
add foreign key (ITEMID)
references T_TOPIC_ITEM (ITEMID) on delete cascade;

hibernate配置如下:

执行查询语句HQL:
from TTopicApplied as a

当数据库中T_TOPIC_APPLIED有数据时程序出现问题:
javax.servlet.ServletException: [BaseAction->execute] Error, message = exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of org.caexpo.expo.model.TTopicApplied.setTopicItemAppliedSet

但数据库中T_TOPIC_APPLIED的没有数据时正常.

太乱 感觉是foreignkey的配置问题

[SDMRauquin]

的确乱，没有合适的开发框架，所以简单的说明就可以了。
因该是Set错了，改成
<many-to-one name="topicItem" column="ITEMID" class="TTopicItem" not-null="true"/ lazy="false" cascade="all"> 试下。
