ssm-企业权限项目-准备

环境准备：

oracle的导入

配置环境：

创建oracle数据库表：

 CREATE TABLE product( id varchar2(32) default SYS_GUID() PRIMARY KEY,
 productNum VARCHAR2(50) NOT NULL, 
 productName VARCHAR2(50), 
 cityName VARCHAR2(50), 
 DepartureTime timestamp,
 productPrice Number,
 productDesc VARCHAR2(500),
 productStatus INT, 
 CONSTRAINT product UNIQUE (id, productNum) )

插入数据：

insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus) values ('676C5BD1D35E429A8C2E114939C5685A', 'itcast-002', '北京三日游', '北京', to_timestamp('10- 10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1); 
insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus) values ('12B7ABF2A4C544568B0A7C69F36BF8B7', 'itcast-003', '上海五日游', '上海', to_timestamp('25- 04-2018 14:30:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1800, '魔都我来了', 0); 
insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice, productdesc, productstatus) values ('9F71F01CB448476DAFB309AA6DF9497F', 'itcast-001', '北京三日游', '北京', to_timestamp('10- 10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1);

OK！！！开始配置Maven环境
将项目分为多个模块，便于二次操作

pom.xml：
我使用的是oracle的jar包，所以maven里没有oracle的依赖坐标

Controller类：查询测试ssm框架整合是否成功，跳转到product-list页面
因为product-list中有很多的图片，所以需要关闭静态资源拦截器，在spring-mvc里面，
这也耗了好久才发现，我真是头猪

/**

@Controller
public class ControllerClient {
    @Autowired
    private IProductService service ;
    @RequestMapping("/findAll")
    public String findAll(Model model){
        List<Product>  productList =service.findAll();
        System.out.println("得到了List集合："+productList);

        model.addAttribute("productList",productList);
        System.out.println("成功添加了productList");
        return "product-list";
    }
}

导入相关页面： 记得关闭EL表达式忽略：
