Spring model attribute silently url-encoded between the controller and the view

[Stephane Eybert]

Hello,

I have a controller building up a url.

The & is not encoded and that is how this url should be.

However, when this url is passed to a model attribute, it ends up being encoded in the JSP view.

Here is the source code of the controller:

	@RequestMapping(value = "/demo", method = RequestMethod.GET)
	public void demo(Model model) throws Exception {
		requestUrl = "1&2";
		logger.debug("=============>>> Controller requestUrl: " + requestUrl);
		model.addAttribute("uploadDocumentLink", requestUrl);
	}

The original value was not url encoded as can be seen in the log:

2012-03-20 13:33:52,290 DEBUG [AnnotateController] =============>>> Controller requestUrl: 1&2

But the JSP page shows it encoded:

http://localhost:8080/annotate-web/1&2

I would like the framework NOT encoded my url, as I want to encode some parts of it only.

I worked around the problem by decoding the variable in the JSP page.

<%@ page import="java.net.URLDecoder"%>
<%
String annotateLink = URLDecoder.decode((String) request.getAttribute("annotateLink"));
String uploadDocumentLink = URLDecoder.decode((String) request.getAttribute("uploadDocumentLink"));
%>
