index.jsp
defult.html
defult.htm
defult.jsp
12.完成Controller
13.index.jsp转发到main
14.选择页面，把代码复制到main.jsp
把资源路径(. . /)改成${pageContext.request.contextPath}/，获取webapp目录下的资源
15.创建Maven配置
第二天
昨天把(. . /)替换成${pageContext.request.contextPath}/时忘记写"/",导致页面没有画面
1.修改成首页显示图片
更改导航栏
2.写查询产品全部信息的SQL
3.修改product-list.jsp页面，并将数据回显
4.修改domain下的Product
5.日期转换字符串的工具类
在domain，dao，service的pom.xml配置ssm_utils
6.
报了个错
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: Connections could not be acquired from the underlying database!
修改driver和url
7.回显成功
第三天
1.把页面头部，导航栏，底部抽取出来
2.产品添加
@Service
@Transactional
public class IProductServiceImpl implements IProductService {
@Autowired
private IProductDao productDao;
/**
* 根据productNum查询产品信息
* @param productNum
* @return
* @throws Exception
*/
@Override
public Product findByNum(String productNum) throws Exception {
if (productNum != null){
Product product = productDao.findByNum(productNum);
if (product != null){
return product;
}
}
return null;
}
/**
* 添加产品信息
* @param product
* @throws Exception
*/
@Override
public void addProduct(Product product) throws Exception {
productDao.addProduct(product);
}
3.修改main页面，创建product-add.jsp
product-add.jsp页面，简单写下
第四天
1.修改昨天写的添加页面
<!--label显示的内容-->
<div class="tab-pane active" id="tab-label">
<form action="${pageContext.request.contextPath}/product/addProduct.do" method="post">
<div class="row data-type">

</div>
</div>
</form>
</div>
<!--label显示的内容/-->
id没给值报错了
给它一个随机数
添加完成了
2.列表的分页
@Controller
@RequestMapping("/product")
public class ProductController {
@Autowired
IProductService productService;
/**
* 查询全部产品信息
* @return
* @throws Exception
*/
@RequestMapping("/findAll.do")
public ModelAndView findAll(@RequestParam(value = "page",defaultValue = "1",required = false)Integer page,@RequestParam(value = "size",defaultValue = "4",required = false) Integer size) throws Exception{
ModelAndView mv = new ModelAndView();
List<Product> productList = productService.findAll(page.intValue(),size.intValue());
PageInfo pageInfo = new PageInfo(productList);
mv.addObject("productList",productList);
mv.addObject("pageInfo",pageInfo);
mv.setViewName("product-list");
return mv;
}
}
报错了
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

dialect改成helperDialect
把db的信息又改成原来的，clean和重启后居然也能启动了，那第二天的报错就感觉挺迷的
3.修改页面
<!-- .box-footer-->
<div class="box-footer">
<div class="pull-left">
<div class="form-group form-inline">
总共${pageInfo.pages}页，共${pageInfo.total}条数据。 每页

</li>
</ul>
</div>
</div>
<!-- /.box-footer-->
第五天
1.选中每页显示多少条数据
2.修改商品信息
修改前查询数据，回显到页面上
<!--label显示的内容-->
<div class="tab-pane active" id="tab-label">
<form action="${pageContext.request.contextPath}/product/updateProduct.do" method="post">

<button type="button" class="btn bg-default" onclick="history.back(-1);">返回</button>
</div>
</div>
</form>
</div>
<!--label显示的内容/-->
修改数据
<!--修改产品信息-->
<update id="updateProduct" parameterType="com.itheima.domain.Product">
update product
set productNum=#{productNum},productName=#{productName},cityName=#{cityName},departureTime=#{departureTime},productPrice=#{productPrice},productDesc=#{productDesc},productStatus=#{productStatus}
where id=#{id}
</update>
3.产品删除
4.没删掉，添加单引号
第六天
1.多选删除
2.产品名称模糊查询
修改相关地址参数信息
/**
* 查询全部产品信息，模糊查询
* @param page
* @param size
* @param fuzzyName
* @return
* @throws Exception
*/
@RequestMapping("/findAll.do")
public ModelAndView findAll(@RequestParam(value = "page",defaultValue = "1")Integer page, @RequestParam(value = "size",defaultValue = "4") Integer size, @RequestParam(value = "fuzzyName",defaultValue = "",required = false) String fuzzyName) throws Exception{
ModelAndView mv = new ModelAndView();
//判断是乱码 (GBK包含全部中文字符；UTF-8则包含全世界所有国家需要用到的字符。)
if (!(Charset.forName("GBK").newEncoder().canEncode(fuzzyName))) {
//转码UTF8
fuzzyName = new String(fuzzyName.getBytes("ISO-8859-1"), "utf-8");
}
List<Product> productList = productService.findAll(page,size,fuzzyName);
PageInfo pageInfo = new PageInfo(productList);
mv.addObject("productList",productList);
mv.addObject("fuzzyName",fuzzyName);
mv.addObject("pageInfo",pageInfo);
mv.setViewName("product-list");
return mv;
}
参数前加@Param注解，防止parameterType的值出现错误
3.刷新功能
产品基本完成了，除了模糊查询和批量删除有些问题
第七天
1.订单管理创建相应数据库表
2.创建相应实体类
3.订单列表分页全查询，订单名称模糊查询
@Controller
