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

1 getHibernateTemplate().setFlushMode(HibernateTemplate.FLUSH_EAGER);

方法2：重写OpenSessionInViewFilter 

 1 package cn.com.farben.framework.util;
 2  
 3 import org.hibernate.FlushMode;
 4 import org.hibernate.Session;
 5 import org.hibernate.SessionFactory;
 6 import org.springframework.dao.DataAccessResourceFailureException;
 7 import org.springframework.orm.hibernate3.SessionFactoryUtils;
 8  
 9 public class OpenSessionInViewFilter extends
10         org.springframework.orm.hibernate3.support.OpenSessionInViewFilter {
11     protected Session getSession(SessionFactory sessionFactory)
12             throws DataAccessResourceFailureException {
13         Session session = SessionFactoryUtils.getSession(sessionFactory, true);
14         session.setFlushMode(FlushMode.COMMIT);
15         return session;
16     }
17  
18     protected void closeSession(Session session, SessionFactory factory) {
19         session.flush();
20         super.closeSession(session, factory);
21     }
22 }

配置web.xml：

 1 <filter>
 2     <filter-name>hibernateFilter</filter-name>
 3     <filter-class>cn.com.farben.framework.util.OpenSessionInViewFilter</filter-class>
 4     <init-param>
 5         <param-name>singleSession</param-name>
 6         <param-value>true</param-value>
 7     </init-param>
 8 </filter>
 9 <filter-mapping> 
10     <filter-name>hibernateFilter</filter-name>  
11     <url-pattern>/*</url-pattern> 
12 </filter-mapping>
