Hibernate laze=true

我的代码

protected Kaoti loadEntity(Serializable id) {
Kaoti obj = (Kaoti) getHibernateTemplate().load(Kaoti.class, id);
return obj;
}

使用get没事，在web.xml 里配置了

<filter>
  <filter-name>OpenSessionInViewFilter</filter-name>
  <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>OpenSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

但还是报下面的错误，
org.hibernate.LazyInitializationException: could not initialize proxy - no Session
