gethibernatetemplate-this.getHibernateTemplate().loadAll(entityClass);

this.getHibernateTemplate().loadAll(entityClass);

這個是我的映射文件
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

我調用List list=this.getHibernateTemplate().loadAll(entityClass);的時候getHibernateTemplate()為空。

頁面提示錯誤：
type Exception report

message

exception

最佳回答：

配置文件有問題！檢查清楚！
