上一篇博客讲了仓库管理系统的货物类别管理功能的实现，这一篇博客我来说说仓库管理系统货物管理功能的实现。其实它和货物类型管理功能相似，只不过比货物类型管理的细节更多一些。但是它们的程序流程是一模一样的。都是先建立数据库表，设置主外键，然后插入值。之后去model包封装数据库货物表字段。在dao包进行控制，在view层进行视图显示。
1：首先在数据库建立数据库表，并插入若干值。
CREATE TABLE t_goods(
id INT PRIMARY KEY AUTO_INCREMENT,
goodsName VARCHAR(20),
goodsSupplier VARCHAR(20),
sex VARCHAR(20),
price DOUBLE,
goodsDesc VARCHAR(200),
goodsTypeId INT,
CONSTRAINT `fk` FOREIGN KEY (`goodsTypeId`) REFERENCES t_goodsType(id)
);
INSERT INTO t_goods VALUES(NULL, 'iphone6+','apple', '男', 6000, '高大上，青年人的喜爱', 3),
(NULL, 'Lige聊Java','Lige', '男', 88.88, '详谈Java开发经验', 2),
(NULL, '发财鱼','广州', '女', 18, '年年发财,年年有余', 4),
(NULL, '红富士','青岛','女', 3, '好吃又可口',1);
2：在model包中进行数据库表字段的封装的代码。
