在项目中使用ssH的时候,会开启OpenSessionInViewFilter来阻止延迟加载的错误,但是在我们开启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如下错误
rg.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.NEVER) - turn your Session into FlushMode.AUTO or remove 'readOnly' marker from transaction definition;
解决办法:直接修改OpenSessionInViewFilter过滤器的配置,配置过滤器的时候配置时候直接指定flushMode。采用下面的方式即可:代码如下: 在web.xml文件中添加如下代码:即可解决延迟加载与上面的错误信息
<!-- hibernate由于设置了延迟加载,在action中并没有真正地查询数据 当跳到jsp页面上要显示数据时,hibernate中的session却已经关闭,导致数据无法显示 该过滤器的作用就是可以避免这种情况 --> <filter> <filter-name>OpenSessionInViewFilter</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> </filter> <filter-mapping> <filter-name>OpenSessionInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
