JSP递增序号

  


<!-- 
     ${vs.count}序号从1开始 

     ${vs.index}序号从0开始 

    ${vs.last}最后一个序号 

    ${vs.first}第一个序号 
-->
            <c:forEach items="${list}" var="books" varStatus="vs">
            <tr>
                <td >
                        ${vs.count}
                </td>
                <td>${books.name}</td>
                <td>${books.bookTypeName}</td>
                <td>${books.price}</td>
                <td>${books.bookNum}</td>
                <td>
                    <a href="/book/update">修改</a>
                </td>
            </tr>
            </tbody>
            </c:forEach>

 

 

JSP遍历List集合

        <table class="table" align="center">
            <thead>
            <tr>
                <th scope="col">序号</th>
                <th scope="col">图书名称</th>
                <th scope="col">图书类型</th>
                <th scope="col">图书价格</th>
                <th scope="col">图书库存</th>
                <th scope="col">操作</th>
            </tr>
            </thead>

            <tbody>

            <c:forEach items="${list}" var="books" varStatus="vs">
            <tr>
                <td >
                        ${vs.count}
                </td>
                <td>${books.name}</td>
                <td>${books.bookTypeName}</td>
                <td>${books.price}</td>
                <td>${books.bookNum}</td>
                <td>
                    <a href="/book/update">修改</a>
                </td>
            </tr>
            </tbody>
            </c:forEach>
        </table>

 

控制器端代码

    /**
     * 查询列表
     */

    @RequestMapping(value ="/list",method = RequestMethod.GET)
    public String  queryBookList(Model model){
        System.out.println("query....");
        List<Book> list = bookService.queryBookList();
        model.addAttribute("list",list);
        //跳转到book-list.jsp页面
        return "book-list";
    }
