解決Hibernate Write operations are not allowed in read-only mode的方法

錯誤信息：

org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.

解決方法：

方法1：在出現異常的方法中加入

getHibernateTemplate().setFlushMode(HibernateTemplate.FLUSH_EAGER);

方法2：重寫OpenSessionInViewFilter 

package cn.com.farben.framework.util;
 
import org.hibernate.FlushMode;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.dao.DataAccessResourceFailureException;
import org.springframework.orm.hibernate3.SessionFactoryUtils;
 
public class OpenSessionInViewFilter extends
        org.springframework.orm.hibernate3.support.OpenSessionInViewFilter {
    protected Session getSession(SessionFactory sessionFactory)
            throws DataAccessResourceFailureException {
        Session session = SessionFactoryUtils.getSession(sessionFactory, true);
        session.setFlushMode(FlushMode.COMMIT);
        return session;
    }
 
    protected void closeSession(Session session, SessionFactory factory) {
        session.flush();
        super.closeSession(session, factory);
    }
}

配置web.xml：

<filter>
    <filter-name>hibernateFilter</filter-name>
    <filter-class>cn.com.farben.framework.util.OpenSessionInViewFilter</filter-class>
    <init-param>
        <param-name>singleSession</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping> 
    <filter-name>hibernateFilter</filter-name>  
    <url-pattern>/*</url-pattern> 
</filter-mapping>
