处理懒加载问题后出现的问题：Write operations are not allowed in read-only mode (FlushMode.NEVE
进行懒加载处理后增加数据出现的问题：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。
Web.xml配置如下：
<filter>?
??? <filter-name>hibernateFilter</filter-name>?
??? <filter-class>?
??????? org.springframework.orm.hibernate3.support.OpenSessionInViewFilter?
??? </filter-class>?
???? <init-param>?
??????? <param-name>singleSession</param-name>?
??????? <param-value>false</param-value>?
??? </init-param>?
</filter>?
<filter-mapping>?
??? <filter-name>hibernateFilter</filter-name>?
??? <url-pattern>/*</url-pattern>?
</filter-mapping>?
?
出现上面的情况是因为之前Web.xml中没有这个
<init-param>?
??????? <param-name>singleSession</param-name>?
??????? <param-value>false</param-value>?
?</init-param>
?
?
或者是把false设置为true：
<init-param>?
??????? <param-name>singleSession</param-name>?
??????? <param-value>true</param-value>?
?</init-param>
