Struts+Hibernate+Sprint结合完美实现

实现接口类：

import org.springframework.orm.hibernate3.support.*;

  * @see com.wu.dao.IEmailDAO#deleteE(int)
  * deleteE方法删除数据 按编号删除
  */
public  boolean deleteE(int emailId){
  try{
   /*
    * load方法加载类。 通过这个对象找到这个编号
    * 调用模版的delete方法 （删除的是个对象）
    */
   EmailInfo obj=(EmailInfo)this.getHibernateTemplate().load(EmailInfo.class, new Integer(emailId));
   this.getHibernateTemplate().delete(obj);
   return true;
  }catch(Exception ex){
   System.out.println(ex.getMessage());
   return false;
  }
}
/*
  * (non-Javadoc)
  * @see com.wu.dao.IEmailDAO#readAllEmail()
  * 读取方法 用模版的find方法
  */

  try{
   String  strSql="from hib.EmailInfo";

  }catch(Exception ex){
   System.out.println(ex.getMessage());
   return null;
  }
}
/*
  * (non-Javadoc)
  * @see com.wu.dao.IEmailDAO#addEmail(java.lang.String, java.lang.String, java.lang.String, java.lang.String)
  *  添加方法  调用用对象来添加
  *  添加的模版用Save方法来保存
  */
public boolean addEmail(String emailfrom, String emailto,
   String emailtitle, String emailcontent) {
  try{
   EmailInfo  email = new EmailInfo();
   email.setEmailfrom(emailfrom);
   email.setEmailto(emailto);

没有层次感，写的太乱！
注释的不专业！有待提高！
