Question

我有一个jsp，form标签内有以下文本区域，以便我可以将XML提交给servlet：

<tr>
    <td align="center">
        <textarea name="xmlreqdoc" rows="20" cols="50"></textarea>
    </td>
</tr>

文本区域是我提交请求XML的地方，我在servlet类中检索提交的XML，如下所示：

String requestXML = pReq.getParameter("xmlreqdoc");

pReq只是HttpServletRequest。

现在，我遇到的问题是，当我通过JSP文本区域提交XML时，String requestXML会返回所有删除的括号，即>和< XML和我不明白为什么？

                        formomv2.action="<%=request.getContextPath()%>/user/create/OMTestClient.do";                        
                        var $form = $('#formomv2');             
                        $.post($form.attr("action"), $form.serialize());

您提交表单的方式似乎是为了使某些字符不会从XML字符串中转义。在提交之前，请尝试serializing您的表单。

由于你正在使用Jquery，你可以尝试这样的事情：

   function postXMLToOMV2(){

         formomv2.submitaction.value="getClientGuid";
         formomv2.action="<%=request.getContextPath()%>/user/create/OMTestClient.do";

         var $form = $('#formomv2');             
         $.post($form.attr("action"), $form.serialize());

         // im not sure where you have declared 'formomv2' but if you have you could probably also just do the following:
         //  $.post(formomv2.attr("action"), formomv2.serialize());

            }

正在从我的Servlet中删除请求XML括号
