struts+spring+hibernate的web应用<四> Web层代码编写(2)

接着就是写资源文件了。
在com.game.resources包中添加ApplicationResourcesProducts.properties文件。如果你的eclipse中有Properties Editor这个插件，就可以用Properties Editor打开资源文件进行编写，省去了用命令行转换格式的麻烦。配置内容如下：


errors.required={0}不能为空.


errors.minlength={0}不能小于 {1} 个字符.


errors.maxlength={0}不能大于 {1} 个字符.


errors.invalid={0}输入格式不对.


errors.byte={0}必须为字节.


errors.short={0}必须为短整型.


errors.integer={0}必须为整型.


errors.long={0}必须为长整型.


errors.float={0}必须为浮点型.


errors.double={0}必须为双精度型.


errors.date={0}不是一个正确的日期或格式不对.


errors.range={0} is not in the range {1} through {2}.


errors.creditcard={0} is not a valid credit card number.


errors.email={0}不是一个有效的email地址.




errors.gameNameCn=游戏中文名称


errors.gameNameEn=游戏英文名称


errors.gameCapacity=碟数


errors.gamePrice=价格

需要注意的是



这一节是不能省去的。

接下来就是写页面文件了。在products文件夹中添加如下页面。

index.jsp页面代码：




<%

@ page contentType="text/html;charset=GBK" language="java" %>




<html>


<head>


<meta http-equiv="Content-Type" content="text/html; charset=GBK"/>


<title>游戏软件管理系统</title>

<body>




<a href="/game/getProducts.do?method=doGetProducts&&flag=1">进入游戏软件管理单元</a>


</body>


</html>



products.jsp页面代码：

String value="";

}


%>


<html>


<head>


<meta http-equiv="Content-Type" content="text/html; charset=GBK"/>


<title></title>




<script language = "JavaScript">

{


if(myfm.value.value=="")






{


alert("请输入查询关键字!");




}else

{


window.location.href="/game/queryProducts.do?method=doQueryProduct&&flag=2&&fieldname="+myfm.fieldname.value+"&&value="+myfm.value.value;


}


}

最后在tld文件夹中添加下列tld文件。



至此，整个项目基本编写完了，运行tomcat，看看我们的项目的效果吧！
在地址栏输入http://localhost:8088/game/products/index.jsp

然后点击“进入游戏软件管理单元”链接，主界面出现了。
