S2SH整合后使用hibernateTemplate的find方法空指针错误
hibernateTemplate的save方法能正常使用，但是当我调用find方法的时候，出现空指针！请问这是为什么？
代码如下：

package com.hotel.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Component;

import com.hotel.dao.MemberDao;
import com.hotel.model.Member;

@Component("memberDao")
public class MemberDaoImpl implements MemberDao{

  private HibernateTemplate hibernateTemplate;
   

public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}

public MemberDaoImpl() {

}
@Resource
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
public void save(Member member) {
hibernateTemplate.save(member);
}

@Override
public List<Member> getMemberList() {
List<Member> members = hibernateTemplate.find("from Member");
System.out.print("=========="+hibernateTemplate);
return members;
}



}


错误信息是：
