访问http://localhost:9101/brand/findAll.do
出现的问题
运行后报错

分页显示一直是web开发中一大烦琐的难题，传统的网页设计只在一个JSP或者ASP页面中书写所有关于数据库操作的代码，那样做分页可能简单一点，但当把网站分层开发后，分页就比较困难了，下面是我做Spring+Hibernate+Struts2项目时设计的分页代码，与大家分享交流。
1、DAO层接口的设计，在MemberDao接口中定义了如下两个方法：
public in
/*
*使用对象类型
*/
--建立和使用简单对象类型
--对象类型包括对象类型规范和对象类型体两部分。
--建立和使用不包含任何方法的对象类型
CREATE OR REPLACE TYPE person_typ1 as OBJECT(
name varchar2(10),gender varchar2(4),birthdate date
);
drop type p
what 什么
your 你
name 名字
my 我的
am 是
one 一
two 二
three 三
four 四
five 五
class 班级，课
six 六
seven 七
eight 八
nince 九
ten 十
zero 零
how 怎样
old 老的
eleven 十一
twelve 十二
thirteen
spring security 3中推荐使用BCrypt算法加密密码了，以前使用的是md5，
Md5PasswordEncoder 和 ShaPasswordEncoder，现在不推荐了，推荐用bcrpt
Bcrpt中的salt可以是随机的，比如：
int i = 0;
while (i < 10) {
String password = "1234
1.前言。
如题。
2.代码
(1)单表查重复数据,根据a分组
SELECT m.a,m.b, INNER JOIN （select a,b,COUNT(*) AS rank FROM test.`A` A GROUP BY a HAVING rank>1 )k ON m.a=k.a
（2）多表查询 ，
使用改为le
