原因代码：

/**

	 */
@SuppressWarnings("unchecked")
public EmailTypeDto selectValidateEmailTypeNo(EmailTypeDto emailTypeDto) {
	EmailTypeDto emailTypeDto1=null;
	String emailTypeNo=null;
	if(StringUtils.isNotBlank(emailTypeDto.getEmailTypeNo())){
	StringBuilder stringBuilder=new StringBuilder("select * from ft_emailType_t where emailTypeNo="+emailTypeNo);
	 Session session=sessionFactory.getCurrentSession();
	    SQLQuery sqlQuery=session.createSQLQuery(stringBuilder.toString());
	    sqlQuery.setResultTransformer(Transformers.aliasToBean(MerchantDto.class));
		List<EmailTypeDto> list = sqlQuery.list();
		if (list != null && !list.isEmpty()) {
			emailTypeDto1=list.get(0);
		}
	}
	return emailTypeDto1;
}

 没有转换为EmailTypeDto，出现的错误。

原因二：

还要注意在Action中private属性预定要实例化new 类名()，否则拦截器也拦截，未对EmailTypeDto进行实例化。
