url encoding of java string in freemarker template file

[Wai]

In a freemarker template, I have the following. Of course, it can also come from a java method.
<#assign test=Static["java.lang.String"].format("http://example.com/page?a=1&b=2") >
<p>result1=${test}</p>
<p>result2=${test?url('utf-8')}</p>

The output to the webbrowser shows...
result1=http://example.com/page?a=1&b=2
result2=http%26%23x3a%3B%26%23x2f%3B%26%23x2f%3Bexample.com%26%23x2f%3Bpage%26%23x3f%3Ba%26%23x3d%3B1%26amp%3Bb%26%23x3d%3B2

I'm interesting in the following correct output...
result1=http://example.com/page?a=1&b=2
result2=http%3A%2F%2Fexample.com%2Fpage%3Fa%3D1%26b%3D2


Could someone tell me what is the problem and how to solve it.
Thanks in advance.

I'm not sure there is a problem? FreeMarker is doing exactly what
you're telling it to do by escaping any URL characters. This behavior
is well documented [1]

So I guess the question is, why and in what context are you using the
url() built-in for.

You can refer UtilCodec class

requestUrl = UtilCodec.getDecoder("url").encode(requestUrl);

requestUrl = UtilCodec.getDecoder("url").decode(requestUrl);

The issue was the actual _result2_ is longer then the desired _result2_. Notice that the actual _result2_ contain many more bytes then the desired.  I think the issue is that a java string is using unicode/utf16. That's why there are so many more bytes.

A solution I used was to create a StringWrapper for the _test_ variable and then use the freemarker ?url method. eg...

<#assign test=Static["java.lang.String"].format("http://example.com/page?a=1&b=2") >
<#assign test=StringUtil.wrapString(test)>
<p>result1=${test}</p>
<p>result2=${test?url('utf-8')}</p>

Resulting output to the browser is...
result1=http://example.com/page?a=1&b=2
result2=http%3A%2F%2Fexample.com%2Fpage%3Fa%3D1%26b%3D2
