急~在线等!!!!: this.getHibernateTemplate()为空 的问题~

Question

如题
我第一次使用SPRING管理HIBERNATE
自己写了一个类:
public class IBaseService extends HibernateDaoSupport{ public void addObject(Object obj) {
String a = "1";
System.out.println(a);
Object o = obj;
try {
  System.out.println(this.getHibernateTemplate());//这里输出为null..
  this.getHibernateTemplate().save(o);
} catch (Exception e) {
e.printStackTrace();
}
}}

我的applicationContext.xml文件是这样的:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans>
<bean id="DataSource"

</property>
<property name="username">

</bean>

<bean id="sessionFactory"

</property>
</bean>
    
</beans>

Answer 2

会不会是我注入的有问题? 请有经验的朋友帮忙看看~很急!
<bean id="ibaseService" class="com.surpner.www.base.IBaseService" abstract="false" singleton="true" lazy-init="default" autowire="default" 
dependency-check="default"> 
<property name="sessionFactory"> 
<ref bean="sessionFactory" /> 
</property> 
</bean> 

Answer 3

就是Spring注入问题
autowire="byType"

Answer 4

singleton="true"
这个东东在"<bean>"里可以配置???
去了它,另外 lazy-init="default" autowire="default" 
都写的默认,那还不如去掉,有啥用..
