Hibernate version:3.1
Name and version of the database you are using:SQL SERVER 2000
I have 3 table,
SYS_USER:
Fields:USER_CODE,USER_NAME
SYS_ORGANIZATION:
Fields:ORG_CODE,ORG_NAME
O_ORG_USER:
Fields:OID,ORG_CODE,USER_CODE
The below code is right
Code:
SysUser sysuser = this.getSysUser(new Long(2000000001));
((OOrgUser)sysuser.getOOrgUsers().iterator().next()).getSysOrganization().getOrgName();
The below code is wrong
Code:
SysOrganization sysorg = this.getSysOrganizationDAO().findById(new Long(1000000000));
((OOrgUser)sysorg.getOOrgUsers().iterator().next()).getSysUser().getOrgName()
SysUser.hbm.xml
Code:
<set name="OOrgUsers" inverse="true" lazy="true">
<key>
<column name="USER_CODE" />
</key>
<one-to-many class="cn.net.ecode.bean.OOrgUser" />
</set>
SysOrganization.hbm.xml
Code:
<set name="OOrgUsers" inverse="true" lazy="true">
<key>
<column name="ORG_CODE" />
</key>
<one-to-many class="cn.net.ecode.bean.OOrgUser" />
</set>
OOrgUser.hbm.xml
Code:
<many-to-one name="sysOrganization" class="cn.net.ecode.bean.SysOrganization">
<column name="ORG_CODE" />
</many-to-one>
<many-to-one name="sysUser" class="cn.net.ecode.bean.SysUser">
<column name="USER_CODE" />
</many-to-one>
Code:
