• 闯关测试心得

    题目概述：1、背景资料： 1、有一个存放商品的仓库，每天都有商品出库和入库。 2、每种商品都有名称、生产厂家、型号、规格等。 3、出入库时必须填写出入库单据，单据包括商品名称、生产厂家、型号、 规格、数量、日期、时间、入库单位（或出库单位）名称、送货（或提货）人 姓名。 2.系统要求与功能设计 2.1 页面要求 （1）能够在 Tomcat 服务器中正确部署，并通过浏览器查看；（1 分） （2）网站页面整体风格统一； 2.2 设计要求 1、设计出入库单据的录入。 2、实现按商品名称、出入库日期的查询。

     首先，需要一个实体类，控制参数。我们需要很多参数，因为这个题目很长，要求很多。商品名称、生产厂家、型号、 规格、数量、日期、时间、入库单位（或出库单位）名称、送货（或提货）人 姓名。茫茫多。

    package bean;

public class bean {
    private String tradename;
    private String manufacturer;
    private String model;
    private String specification;
    private String number;
    private String time;
    private String company;
    private String name;
    public bean() {
    }
    public String getTradename() {
        return tradename;
    }
    public void setTradename(String tradename) {
        this.tradename = tradename;
    }
    public String getManufacturer() {
        return manufacturer;
    }
    public void setManufacturer(String manufacturer) {
        this.manufacturer = manufacturer;
    }
    public String getModel() {
        return model;
    }
    public void setModel(String model) {
        this.model = model;
    }
    public String getSpecification() {
        return specification;
    }
    public void setSpecification(String specification) {
        this.specification = specification;
    }
    public String getNumber() {
        return number;
    }
    public void setNumber(String number) {
        this.number = number;
    }
    public String getTime() {
        return time;
    }
    public void setTime(String time) {
        this.time = time;
    }
    public String getCompany() {
        return company;
    }
    public void setCompany(String company) {
        this.company = company;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    

}

    很好写，只要脑子没什么大问题。不过别忘了给构造函数。

                     psql.executeUpdate();
                     System.out.println("修改成功！！");
                     request.getRequestDispatcher("/firstpage.jsp").forward(request,response);
                }
                else if(rs.isLast()) {
                    request.getRequestDispatcher("/queryfalse.jsp").forward(request,response);
                }
            }
           rs.close();
           con.close();
           psql.close();
        }catch(SQLException e) {
            //数据库连接失败异常处理
            e.printStackTrace();  
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }
    }

}

    这个是改，本来啊，我不应该用这么长时间的，但是确实是很不熟练，而且参数有点多.....有点眼睛疼，中途有两次连不上数据库，最重点的是开头的时候题意没理解清绕了远路。

    录入界面，四个主界面里最好写的

    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

</head>
<body>
<form id="form1" action="/shopping/Bservlet" method="post">
    <tr>
        <td>
            商品名称:<input type="text" id="tradename" name="tradename"/>    
        </td>
    </tr>
    <tr>
        <td>
            <button type="submit" id="sub" value="">提交</button>    
        </td>
    </tr>
</form>
<form action="firstpage.jsp" method="post">
    <tr>
        <td>
            <button type="submit" id="sub" value="">返回首页</button>    
        </td>
    </tr>
</form>
</body>
</html>

    通过商品的名字进行查询。

    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

<body>
<form id="form1" action="/shopping/Dservlet" method="post">

        <tr>
            <td>
                商品名称:<input type="text" id="tradename" name="tradename"/>
            </td>
        </tr>
        <tr>
            <td>
                生产厂家:<input type="text" id="manufacturer" name="manufacturer"/>
            </td>
        </tr>
        <tr>
            <td>
                商品型号:<input type="text" id="model" name="model"/>
            </td>
        </tr>
        <tr>
            <td>
                商品规格:<input type="text" id="specification" name="specification"/>
            </td>
        </tr>
        <tr>
            <td>
                商品数量:<input type="text" id="number" name="number"/>
            </td>
        </tr>    
        <tr>
            <td>
                单据时间:<input type="text" id="time" name="time"/>
            </td>
        </tr>
        <tr>
            <td>
                提货单位:<input type="text" id="company" name="company"/>
            </td>
        </tr>
        <tr>
            <td>
                提货姓名:<input type="text" id="name" name="name"/>
            </td>
        </tr>
        <tr>
            <td>
                <button type="submit" id="sub" value="">提交</button>
            </td>
        </tr>
    </table>
</form>
</body>
</html>

    更改界面

    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>未查询到此种商品...</title>
</head>
<body>
<h2>未查询到此种商品......</h2>
<form action="firstpage.jsp">
    <button type="submit" id="sub" value="">返回首页</button>
</form>
</body>
</html>

    查询失败界面

    <%@ page import="bean.bean" %>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>查询结果</title>
</head>
<body>
<%bean bean=(bean)request.getAttribute("b"); %>
    <%System.out.print(bean.getTradename()); %>
    <h2>商品名称:<%=bean.getTradename()%></h2>
    <h2>生产厂家:<%=bean.getManufacturer() %></h2>
    <h2>商品型号:<%=bean.getModel() %></h2>
    <h2>商品规格:<%=bean.getSpecification() %></h2>
    <h2>商品数量:<%=bean.getNumber() %></h2>
    <h2>单据时间:<%=bean.getTime() %></h2>
    <h2>提货单位:<%=bean.getCompany() %></h2>
    <h2>提货姓名:<%=bean.getName() %></h2>
<form action="Newrevise.jsp" method="post" >
    <button type="submit" id="sub1" value="">修改</button>
</form>
<form action="firstpage.jsp" method="post" >
    <button type="submit" id="sub1" value="">回到首页</button>
</form>
</body>
</html>

    查询显示，可以说是比较麻烦的一个jsp

    <%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>修改</title>
</head>
<body>
<form action="/shopping/Bservlet" method="post" id="form1">
    <tr>
        <td>
            商品名称:<input type="text" id="tradename" name="tradename"/>
        </td>
    </tr>
    <tr>
        <td>
            <button type="submit" id="sub" value="">提交</button>    
        </td>
    </tr>
</form>
<form action="firstpage.jsp" method="post">
    <tr>
        <td>
            <button type="submit" id="sub" value="">返回首页</button>    
        </td>
    </tr>
</form>
</body>
</html>

    修改界面，到此为止就算是都写完了。

    总的来看这道题目，其实还算中规中矩，不过之前学长们的影响还是比较深的，想套人家的模板，结果失败了。所以说还是扎扎实实的，自己写比较好。

    另外一点，我其实最大的短板是jsp语言，不然也用不了这么久的时间去做。还是说功力不够，练习时间太短啦。
