可能是你的spring的配置问题，能贴一下详细的错误信息和配置代码吗

Answer 2

在web.xml加这段代码试试
<filter>
<filter-name>openSessionInView</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>openSessionInView</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

是不是 *.hbm.xml 中的哪个 多对一 或者 一对多 的配置上 没有写 lazy="false" 把？
