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

错误信息：

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.

解决方法：

方法1：在出现异常的方法中加入

 getHibernateTemplate().setFlushMode(HibernateTemplate.FLUSH_EAGER);

方法2：重写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>
