异常积累：org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode （转载）

转载:文章来源：http://lucky16.iteye.com/blog/673903此异常是由于Spring提供的Open Session In View而引起的。 
       
       开启OpenSessionInViewFilter这个过滤器的时候FlushMode就已经被默认设置为了MANUAL，如果FlushMode是MANUAL或NEVEL,在操作过程中 hibernate会将事务设置为readonly，所以在增加、删除或修改操作过程中会出现该错误  
      <filter>
       <filter-name>hibernateFilter</filter-name>
       <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
          <init-param>
               <param-name>flushMode</param-name>
               <param-value>AUTO</param-value>
           </init-param>
       <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>
