宜立方商城----****导入和框架整合
****导入
在服务器上安装MySQL
第一步：使用yum list mysql*
第二步：使用命令安装yum install mysql*
用navicat_mysql软件连接数据库并导入表
在左边空白处右键--新建数据库---设置编码集和数据库名
在建好的数据库上右键----运行sql文件---找到已经准备好的sql文件，执行即可
这样就得到了一个数据库
使用****生成mapper和pojo文件
File--inport--
根据自己的实际情况修改连接数据库的配置文件
执行该文件即可
ssm框架整合
整合思路
Dao层：
Mybatis的配置文件：SqlMapConfig.xml
不需要配置任何内容，需要有文件头。文件必须存在。
applicationContext-dao.xml：
mybatis整合spring，通过由spring创建数据库连接池，spring管理SqlSessionFactory、mapper代理对象。需要mybatis和spring的整合包。
Service层：
applicationContext-service.xml：
所有的service实现类都放到spring容器中管理。并由spring管理事务。
表现层：
Springmvc框架，由springmvc管理controller。
Springmvc的三大组件。
在e3-manager\e3-manager-web\src\main\resources目录下创建三个文件夹conf mybatis spring

e3-manager\e3-manager-web\src\main\resources\mybatis：SqlMapConfig.xml

需求
根据商品id查询商品信息，返回json数据。(ItemService)
Dao层
由于是单表查询可以使用****生成的代码
Service层
参数：商品id
返回值：TbItem
业务逻辑：根据商品id查询商品信息。
编写interface接口
package cn.e3mall.service;
import cn.e3mall.pojo.TbItem;
public interface ItemService {
/**
* 根据id查询商品
* @param id
* @return
*/
public TbItem getItemById(long id);
}
编写实现类
package cn.e3mall.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import cn.e3mall.mapper.TbItemMapper;
import cn.e3mall.pojo.TbItem;
@Service
public class ItemServiceImpl implements ItemService {
@Autowired
private TbItemMapper itemMapper;
@Override
public TbItem getItemById(long id) {
TbItem item = itemMapper.selectByPrimaryKey(id);
return item;
}
}
表现层
package cn.e3mall.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import cn.e3mall.pojo.TbItem;
import cn.e3mall.service.ItemService;
@Controller
public class ItemController {
@Autowired
private ItemService itemService;
@RequestMapping("item/{itemId}")
@ResponseBody
private TbItem getItemById(@PathVariable Long itemId){
TbItem item = itemService.getItemById(itemId);
return item;
}
}
