Spring控制的Hibernate的生命周期只針對數(shù)據(jù)層和服務層,表現(xiàn)層就沒這個福分了還有就是只有在session沒有關閉的情況下運行Obj.getXxx()時才會執(zhí)行select語句從數(shù)據(jù)庫加載對象（這就是所謂的延遲加載）session已經(jīng)關閉，此時再運行Obj.getXxx()方法，Hibernate就會拋出"Could not initialize proxy - the owning Session was closeed"的異常。不過可以通過 org.springframework.orm.hibernate3.support.OpenSessionInViewFilter過濾器來彌補這一缺陷。在WEB.XML中加入以下內(nèi)容：
<filter>
  <filter-name>hibernateFilter</filter-name>
  <filter-class>
   org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
  </filter-class>
  <!-- singleSession默認為true,若設為false則等于沒用OpenSessionInView -->
  <init-param>
   <param-name>singleSession</param-name>
   <param-value>true</param-value>
  </init-param>
 </filter>
<filter-mapping>
  <filter-name>hibernateFilter</filter-name>
  <url-pattern>*.do</url-pattern>
 </filter-mapping>

==============如果還是不行則在DAO里加入Hibernate.initialize(Obj.getXxx());
