Hibernate version:2.1

when i load or query a project or user, hibernate will auto update the project or user which was loaded by select.

why?

User.hbm.xml:

Hibernate: select uservo0_.ID as ID0_, uservo0_.username as username0_, uservo0_.password as password0_, uservo0_.fullname as fullname0_, uservo0_.email as email0_, uservo0_.createDate as createDate0_, uservo0_.modifyDate as modifyDate0_, uservo0_.isLogin as isLogin0_, uservo0_.lastLoginDate as lastLogi9_0_, uservo0_.lastLoginIP as lastLog10_0_ from users uservo0_ where uservo0_.ID=?

2005-08-14 13:43:35,481 [org.springframework.orm.hibernate.HibernateTransactionManager]-[INFO] Initiating transaction commit

Hibernate: update users set username=?, password=?, fullname=?, email=?, createDate=?, modifyDate=?, isLogin=?, lastLoginDate=?, lastLoginIP=? where ID=?

2005-08-14 13:43:35,517 [org.springframework.orm.hibernate.HibernateTransactionManager]-[INFO] Initiating transaction commit

Thanks in advance!

<bean id="baseTransactionProxy"
class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="transactionManager">
<ref bean="transactionManager" />
</property>
<property name="transactionAttributes">
<prop key=".*add.*">PROPAGATION_REQUIRED</prop>
<prop key=".*del.*">PROPAGATION_REQUIRED</prop>
<prop key=".*update.*">PROPAGATION_REQUIRED</prop>
<prop key="*">PROPAGATION_REQUIRED</prop> </property>
</bean>

i changed this to:

<prop key="*add*">PROPAGATION_REQUIRED</prop>
<prop key="*del*">PROPAGATION_REQUIRED</prop>
<prop key="*update*">PROPAGATION_REQUIRED</prop>
<prop key="*">PROPAGATION_REQUIRED,readOnly</prop>

this is ok!

try it!

i used the spring to control transaction.
