How do I disable escaping of a URL (particularly the &) in a Thymeleaf template?

Question

I'm passing a bean QuoteOption into the model that has a method called getCachedImageUrl(url, width, height) that returns a URL for the image.

My Thymeleaf template:

<img th:src="${quoteOption.getCachedImageUrl(baseUrl,300,200)}" />

Generates

<img src="http://nitro:8080/image/nitro-resources-development/28f08e67-96c9-4bb4-8012-9e34040cc976.jpeg?width=300&amp;height=200" />

Notice the & in the url parameters! Aaaargh! How do I instruct Thymeleaf to not escape the ampersand?

Answer 1

Bean with name someBean:

public class SomeBean {

       public String testMethod() {
            return "http://nitro:8080/image/nitro-resources-development/28f08e67-96c9-4bb4-8012-9e34040cc976.jpeg?width=300&height=200";
        }
}

In Thymeleaf :

  <img th:src="${@applicationCache.testMethod()}" id="_Bhuwan"/>
  <button onclick="alert($('#_Bhuwan').attr('src'))">See</button>

Two Case :

1. In alert Show message as :

   http://nitro:8080/image/nitro-resources-development/28f08e67-96c9-4bb4-8012-9e34040cc976.jpeg?width=300&height=200

2. In View Page Source or Edit HTML in Browser. Generate :

   <img src="http://nitro:8080/image/nitro-resources-development/28f08e67-96c9-4bb4-8012-9e34040cc976.jpeg?width=300&amp;height=200">

So that actual value in src attribute of img tag is http://nitro:8080/image/nitro-resources-development/28f08e67-96c9-4bb4-8012-9e34040cc976.jpeg?width=300&height=200 in this case. But when we try see value using View Page source or edit html through browser then Browser may escape & char to &.

Tested On Themeleaf version is 2.1.4.RELEASE in Spring 4.
