Hibernate 我无法更新我的对象

我正在用hibernate构建一个SpringWeb应用程序。我不知道为什么，但我不能更新我的对象。低于我的配置

<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="luxpolDataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.fixus.luxpol.bean.House</value>
            <value>com.fixus.luxpol.bean.Photo</value>
            <value>com.fixus.luxpol.bean.Service</value>
            <value>com.fixus.luxpol.bean.User</value>
            <value>com.fixus.luxpol.bean.AccountRole</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>                         
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

<mvc:annotation-driven />
<context:component-scan base-package="com.fixus.luxpol" />
<context:component-scan base-package="com.fixus.luxpol.bean" />

<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="luxpolDataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.fixus.luxpol.bean.House</value>
            <value>com.fixus.luxpol.bean.Photo</value>
            <value>com.fixus.luxpol.bean.Service</value>
            <value>com.fixus.luxpol.bean.User</value>
            <value>com.fixus.luxpol.bean.AccountRole</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>                         
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

<mvc:annotation-driven />
<context:component-scan base-package="com.fixus.luxpol" />
<context:component-scan base-package="com.fixus.luxpol.bean" />

我使用update（objectobj）方法使用hibernate模板进行更新

<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="luxpolDataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.fixus.luxpol.bean.House</value>
            <value>com.fixus.luxpol.bean.Photo</value>
            <value>com.fixus.luxpol.bean.Service</value>
            <value>com.fixus.luxpol.bean.User</value>
            <value>com.fixus.luxpol.bean.AccountRole</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>                         
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

<mvc:annotation-driven />
<context:component-scan base-package="com.fixus.luxpol" />
<context:component-scan base-package="com.fixus.luxpol.bean" />

----更新

<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="luxpolDataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.fixus.luxpol.bean.House</value>
            <value>com.fixus.luxpol.bean.Photo</value>
            <value>com.fixus.luxpol.bean.Service</value>
            <value>com.fixus.luxpol.bean.User</value>

            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>

<context:component-scan base-package="com.fixus.luxpol.bean" />

我已经检查了我的问题。我将方法从update更改为saveOrUpdate，它总是在数据库中创建新记录。我应该说我是通过表单发送这个对象的。我的意思是，我有一个带有对象属性的表单，并且我通过POST to方法发送它，在该方法中我调用了update（saveOrUpdate）方法

<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="luxpolDataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.fixus.luxpol.bean.House</value>
            <value>com.fixus.luxpol.bean.Photo</value>
            <value>com.fixus.luxpol.bean.Service</value>
            <value>com.fixus.luxpol.bean.User</value>
            <value>com.fixus.luxpol.bean.AccountRole</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>                         
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

<mvc:annotation-driven />
<context:component-scan base-package="com.fixus.luxpol" />
<context:component-scan base-package="com.fixus.luxpol.bean" />

我在logger中获取标题，因此对象被传递。我应该使用House对象的控制器来创建此对象的实例吗

<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="luxpolDataSource" />
    <property name="annotatedClasses">
        <list>
            <value>com.fixus.luxpol.bean.House</value>
            <value>com.fixus.luxpol.bean.Photo</value>
            <value>com.fixus.luxpol.bean.Service</value>
            <value>com.fixus.luxpol.bean.User</value>
            <value>com.fixus.luxpol.bean.AccountRole</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>                         
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

好的，问题解决了。有时候我真是太笨了。我没有通过表单传递id，因此更新方法无法工作。抱歉占用您的时间

您在更新任何实体时都会收到此消息吗？不会。我刚刚检查了不同的实体，它工作正常。我应该在此处配置事务管理器吗？我找不到问题所在。一个实体起作用，但该实体不希望：(
