How can I unescape HTML escape character from JSP to Java

Question

I am applying fn:escapeXml to a input value (say > ) in JSP to do html escape. When I submit the form, I do need to send the parameter to the controller. In my controller, the request parameter comes as &gt and not > . Because of this, I could not unescape in the controller to get the original value. Could anyone help on this?

Use one of the unescape methods.

一种解决方案是，创建一个自定义方法，并用>替换所有出现的＆gt字符串，并对其他html字符执行类似的操作。
