產品模塊

查詢所有商品

ProductController

@Controller
@RequestMapping("/product")
public class ProductController {
    @Autowired
    ProductService productService;
    /**
     * 查詢全部
     * @return
     */
    @RequestMapping("/findAll")
    public ModelAndView findAll(){
        //準備數據
        List<Product> productList = productService.findAll();
        //創建modelandview
        ModelAndView modelAndView = new ModelAndView();
        //添加數據
        modelAndView.addObject("productList",productList);
        //指定頁面
        modelAndView.setViewName("product-list");
        return modelAndView;

    }
}

ProductService

@Service
public class ProductServiceImpl implements ProductService {
    @Autowired
    ProductDao productDao;
    @Override
    public List<Product> findAll() {
        return productDao.findAll();
    }
}

ProductDao

public interface ProductDao {
    @Select("select * from product")
    List<Product> findAll();
}

前端頁面

<tbody>
	<%--
		循環標籤foreach
		items：要循環的集合對象
		var：循環中的每一個對象
	--%>
	<c:forEach items="${productList}" var="product">
	<tr>
		<td><input name="ids" type="checkbox"></td>
		<td>${product.id}</td>

		<td>${product.productNum}</td>
		<td>${product.productName}</td>
		<td>${product.cityName}</td>
		<td>
			<%--日期格式化--%>
			<fmt:formatDate value="${product.departureTime}" pattern="yyyy-MM-dd HH:mm"></fmt:formatDate>
		</td>
		<td>${product.productPrice}</td>
		<td>${product.productStatus == 1?"開啓":"關閉"}</td>


		<td class="text-center">
			<button type="button" class="btn bg-olive btn-xs"
				onclick='location.href="all-order-manage-edit.html"'>訂單</button>
			<button type="button" class="btn bg-olive btn-xs"
				onclick='location.href="${pageContext.request.contextPath}/product/updateUI?id=${product.id}"'>修改</button>
		</td>
	</tr>
	</c:forEach>


</tbody>

添加產品

ProductController

/**
     * 保存產品
     * @param product
     * @return
     */
    @RequestMapping("/save")
    public String save(Product product){
        //保存操作
        productService.save(product);
        //跳轉查詢全部
        return "redirect:/product/findAll";
    }

ProductService

@Override
    public void save(Product product) {
        productDao.save(product);
    }

ProductDao

//@Insert("insert into product values(product_seq.nextval,#{productNum},#{productName},#{cityName},#{departureTime},#{productPrice},#{productDesc},#{productStatus})")
    //keyProperty 主鍵的屬性名
    //keyColumn 主鍵列名
    //before 在添加之前或之後獲取主鍵
    //resultType主鍵類型
    //statement 獲取主鍵的sql語句
        //mysql:select last_insert_id();
        //oracle:select product_seq.nextval from dual
    @SelectKey(keyProperty = "id", keyColumn = "id",before = true, resultType = Integer.class,
    statement = "select product_seq.nextval from dual" )
    @Insert("insert into product values(#{id},#{productNum},#{productName},#{cityName},#{departureTime},#{productPrice},#{productDesc},#{productStatus})")
    void save(Product product);

自定義類型轉換器StringToDate

類寫完之後，在spring-web.xml中，也需要添加配置

public class StringToDateConverter implements Converter<String,Date> {
    @Override
    public Date convert(String s) {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm");
        try {
            Date date = sdf.parse(s);
            return date;
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return null;
    }
}

<!--開啓註解-->
    <mvc:annotation-driven conversion-service="conversionService"/>

    <!--創建類型轉換器工廠類對象-->
    <bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <bean class="com.itheima.converter.StringToDateConverter"></bean>
            </set>
        </property>
    </bean>

修改產品之數據回顯

ProductController

@RequestMapping("/updateUI")
    public ModelAndView updateUI(Integer id){
        //根據查詢產品對象
        Product product = productService.findById(id);
        //創建ModelAndView對象
        ModelAndView modelAndView = new ModelAndView();
        //添加數據
        modelAndView.addObject("product",product);
        //指定頁面
        modelAndView.setViewName("product-update");
        return modelAndView;
    }

ProductService

@Override
    public Product findById(Integer id) {
        return productDao.findById(id);
    }

ProductDao

在pojo中添加一個屬性爲departureTime，方便回顯String類型的日期

@Select("select p.*,to_char(departureTime,'yyyy-mm-dd hh24:mi') departureTimeStr from product p where id = #{id}")
Product findById(Integer id);

前端

前端顯示略

下拉菜單的正確顯示，id爲productStatus

<script type="text/javascript">
		//更改產品的狀態
		//productStatus option得到select的所有option
		//#productStatus option[value = 1]得到select中value=1的所有option
		//prop：設置標籤選擇性的屬性
		$("#productStatus option[value = ${product.productStatus}]").prop("selected","selected");
	</script>

修改產品

ProductController

@RequestMapping("/update")
    public String update(Product product){
        productService.update(product);
        return "redirect:/product/findAll";
    }

ProductService

/**
     * 更新產品
     * @param product
     */
    @Override
    public void update(Product product) {
        productDao.update(product);
    }

ProductDao

@Update("update product set productNum = #{productNum},productName = #{productName},cityName = #{cityName},departureTime = #{departureTime},productPrice = #{productPrice},productDesc = #{productDesc},productStatus = #{productStatus} where id = #{id}")
    void update(Product product);

刪除產品

ProductController

/**
     * 刪除單個產品
     * @param id
     * @return
     */

前端頁面

<script type="text/javascript">
		function delOne(id) {
			if(confirm("您確定要刪除嗎？")){
				//執行刪除操作
				location.href="${pageContext.request.contextPath}/product/delOne?id="+id;
			}
		}
	</script>

刪除多個產品

前端

首先用form表單，把顯示產品列表的代碼括起來（注意form表單需要放在table標籤外）
使用jQuery，點擊在form表單外的刪除按鈕，執行提交

/刪除多個
		//刪除多個
		function delMany() {
			if(confirm("您確定要刪除選擇的產品嗎？")) {
				//獲取表單
				//document.forms 得到所有表單
				var delForm = $("#delForm");
				//表單提交
				//submit：表單對象執行提交操作
				delForm.submit();
			}
		}

ProductController

 /**
     * 刪除多個
     * @param ids
     * @return
     */
    @RequestMapping("/delMany")
    public String delMany(Integer[] ids){
        //執行刪除操作
        productService.delMany(ids);
        return "redirect:/product/findAll";
    }

ProductService

@Override
    public void delMany(Integer[] ids) {
        //判斷ids是否爲null
        if(ids!=null){
            //遍歷ids，刪除多個產品
            for (Integer id : ids) {
                productDao.delOne(id);
            }
        }
    }

ProductDao

/**
     * 根據id刪除產品
     * @param id
     */
    @Delete("delete from product where id = #{id}")
    void delOne(Integer id);
