hibernateTemplate保存时提示FlushMode.NEVER/MANUAL错误

Question

错误信息：
[code="java"]javax.servlet.ServletException: 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.
org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:515)
org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:421)
org.apache.struts2.dispatcher.ActionContextCleanUp.doFilter(ActionContextCleanUp.java:99)
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter.doFilterInternal(OpenSessionInViewFilter.java:198)
org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76)[/code]

执行这个方法时报错：
[code="java"] public void save(Article transientInstance) {
try {
System.out.println(getHibernateTemplate().getFlushMode());//此处打印1
getHibernateTemplate().save(transientInstance);
} catch (RuntimeException re) {
throw re;
}
}[/code]
