区分'<'以及使用 PortletRequest.getParameter() 的编码等效项

我正在为 IBM WebSphere Portal 6.1 编写 JSR 286 portlet。我有以下代码：

@ProcessAction(name="processForm")
public void processForm(ActionRequest request, ActionResponse response) 
    throws PortletException, IOException {    

    String formField1 = request.getParameter("formField1"));
    System.err.println("formField1: " + formField1);
}

如果用户提交 '<'在 HTML 表单上，系统输出：

formField1: '&lt;'

但是，如果用户提交 '<'在 HTML 表单上，系统还会输出：

formField1: '&lt;'

这使得无法确定用户实际在 HTML 表单中输入的值。有办法解决这个问题吗？

我在此处找到了一篇文章，建议执行直接替换，但它没有解决区分表单上两个不同值的问题。

I'm writing a JSR 286 portlet for IBM WebSphere Portal 6.1. I have the following code:

@ProcessAction(name="processForm")
public void processForm(ActionRequest request, ActionResponse response) 
    throws PortletException, IOException {    

    String formField1 = request.getParameter("formField1"));
    System.err.println("formField1: " + formField1);
}

If the user submits '<' on the HTML form, the system outputs:

formField1: '<'

However, if the user submits '<' on the HTML form, the system also outputs:

formField1: '<'

This makes it impossible to determine which value the user actually typed into the HTML form. Is there a way around this?

I found an article here which recommends doing a straight replace, but it doesn't address the issue of distinguishing between the two different values on the form.
