SSH+Oracle的整合（SSH与Oracle整合坑巨多）

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;

commit;

Goods.hbm.xml

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。
