Thymeleaf rendering error when using ampersand in script tag

Question

I want to add google map javascript to a Thymeleaf template, like this:

https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places

It throws the exception:

org.xml.sax.SAXParseException; lineNumber: 209; columnNumber: 93; The reference to entity "key" must end with the ';' delimiter

I tried to change & to & but nothing changed.

Your help will be greatly appreciated. Thanks!

Because Thymeleaf template is XML, you should use `&` instead of `&` in attribute values. — Ken Bekov, Feb 18 '16 at 04:14
You have to encode & into &.Because & is an escaped sequence of & and the XML would find it as a literal. — ShihabSoft, Feb 18 '16 at 04:39

Thymeleaf uses XML parser, and the character & is considered a special character in XML. You have to replace & with its XML equvilant &.Your URL will be:

https://maps.googleapis.com/maps/api/js?v=3.exp&amp;libraries=places

In thymeleaf 3, it won't be a problem since they wrote a new parser for thymeleaf.

@Aboodz , in this case Spring returns 400. Required parameter 'someParam' is not present. – Erlan Sep 18 '17 at 08:26

It was a bug in Thymeleaf but it was fixed since 2.1.4.

Look at this issue. (The trouble described in this question).

Like this : Is there anything wrong ? – Frans Filasta Pratama Feb 18 '16 at 05:15
I think it must looks like that : ` – sanluck Feb 18 '16 at 05:18
Please [see this file](http://www.thymeleaf.org/doc/articles/standardurlsyntax.html) P.S. I posted incorrect URL, it must be ` – sanluck Feb 18 '16 at 05:50
it throws an exception like this `org.thymeleaf.exceptions.TemplateProcessingException: Could not parse as expression: "@{https://maps.googleapis.com/maps/api/js(v=3.exp,key=xxx,libraries=plac‌es‌)}"` – Frans Filasta Pratama Feb 18 '16 at 07:20

You have some options:

1) Don't use the th:src at all.

2) Since the URL is absolute, you can add it server-side using a static method:

<script th:src="${@urlService.getMapsUrl()}">...</script>

3) Use a rewrite filter.

Not sure whether the issue is corrected in Thymeleaf 3, but it could be worth upgrading quickly and taking a look.
