Question

我在jsp中创建了一个简单的表单

<table class="entry">
    <tr>
        <th width="30%">
            <s:text name="location.label.country"/>
        </th>
        <td width="70%">
            <s:select list="@com.dmainc.commons.stuff.geo.StateUtils@getFormattedCountries()" headerKey="" headerValue="[Please Select]" listKey="abbreviation" listValue="prettyName" name="location.country" id="country_%{tabId}"/>
        </td>
    </tr>
    <tr>
        <th>
            <s:text name="location.label.address1"/>
        </th>
        <td>
            <s:textfield cssStyle="width: 19em" name="location.address1" id="address1_%{tabId}" cssClass="full"/>
        </td>
    </tr>
</table>

我正在使用struts验证器来验证字段。因此，每当我在address1（例如Test＃）文本框中放置带符号＃的内容时，验证器就会在国家/地区字段上抛出NullPointerException。它也会从地址1字段中修剪＃。它适用于其他符号。有没有charset问题？任何帮助/建议都将受到高度赞赏

编辑：验证器：

   @Override
   public void validate()
   {
      if(location.getCountry().equalsIgnoreCase("US"))
      {
         addFieldError("country", "State & Country mismatch!");
         addFieldError("state", "State & Country mismatch!");
      }
   }

在if块

中获取空指针

更新：完成jsp页面

Answer 2

我的问题通过在javascript中用＃23替换＃来解决。

address1 = address1.replace("#","%23");

Special Char＆＃39;＃＆＃39;在struts验证器中创建问题
