这里用SSH+Oracle做一个仓库管理系统，其中包含了查询、条件查询、删除、批量删除、修改、添加的功能。值得注意的是，Oracle与其它数据库存在很多不同之处，所以SSH和Oracle整合的时候小细节处理稍有不慎，就要花费大量时间去排查，亲身体会！
下面进入正文 ↓↓↓↓
Oracle数据库：
goods.sql
注意：创建表的时候，无论表名大写小写，创建完成时都会默认设置成大写。
--创建仓库表
create table goods
(
Gno number not null primary key, --编号
gname varchar2(500) not null, --物质名称
gtype varchar2(20) not null, --物质类型
Gnumber number not null check (Gnumber > 0), --物质数量
Gcompany varchar2(500) not null, --生产商
Gcreatetime date default sysdate, --生产日期
Uintime date default sysdate --入库时间
);
drop table goods;
--创建自增序列
create sequence goods_id
increment by 1 --增量为1
start with 1 --从1开始生成序列
nomaxvalue; --没有最大值
--插入数据
insert into goods(Gno,gname,gtype,gnumber,gcompany) values(goods_id.nextval,‘康师傅方便面‘,‘食品‘,‘150000‘,‘康师傅食品有限公司‘);
insert into goods(Gno,gname,gtype,gnumber,gcompany) values(goods_id.nextval,‘康师傅矿泉水‘,‘饮用水‘,‘150000‘,‘康师傅食品有限公司‘);
insert into goods(Gno,gname,gtype,gnumber,gcompany) values(goods_id.nextval,‘康师傅辣条‘,‘食品‘,‘150000‘,‘康师傅食品有限公司‘);
insert into goods(Gno,gname,gtype,gnumber,gcompany) values(goods_id.nextval,‘康师傅可乐‘,‘食品‘,‘150000‘,‘康师傅食品有限公司‘);
insert into goods(Gno,gname,gtype,gnumber,gcompany) values(goods_id.nextval,‘康师傅面包‘,‘食品‘,‘150000‘,‘康师傅食品有限公司‘);
select * from goods;
select * from goods order by gcreatetime desc;

注意：
1.table需要写全称。
2.dynamic-insert和dynamic-update表示是否启动默认值，如果没有设置true则数据库中默认的字段会为空。
3.主键生成策略为increment，其它无效，不知道为什么。
