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 >
</ head >
< 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：

<% @page pageEncoding="GBK" contentType="text/html; charset=GBK" import="com.game.commons.Pager;" %>

    value=(String)request.getAttribute("value");
}
%>

< script  language  = "JavaScript" >
function btnQuery() {
    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。
