Hope that helps Your question is not entirely clear to me but I guess this is what you are looking for
code :
void main() {
  ClassMirror cm = reflectClass(Zoo);
  cm.declarations.forEach((k, v) {
    if(v is VariableMirror) {
      if ((v as VariableMirror).type.typeArguments.where((t) => t.isSubtypeOf(reflectType(Animal))).length > 0) {
        print('$k, $v');
      }
    }
  });
}

help you fix your problem Without the HTML you're making it a lot harder, but after some digging into the inspect output, I think I have a reasonable HTML snippet.
This is how I'd go about getting to the tag:
code :
require 'nokogiri'

doc = Nokogiri::HTML(<<EOT)
<a action-type="8" class="a-n g-s-n-aa g-s-n-aa Gbb EjFvwd VP" target="_top" href="./104882190640970316938/about">
    <div style="height:110px; width:110px;">
        <img style=" height: 110px; width: 110px;" class="mja" src="https://mts0.google.com/vt/data=TSwRVVf0DGlwBQqarpBU3wUz-i2gqbuWEbxTilWKINf30Au9l0oLM_ojk4KI0oPUi8kL5fJaJWte45O3abOXMzE3L7xDBg">
    </div>
</a>
EOT

doc.at('img')['src'] # => "https://mts0.google.com/vt/data=TSwRVVf0DGlwBQqarpBU3wUz-i2gqbuWEbxTilWKINf30Au9l0oLM_ojk4KI0oPUi8kL5fJaJWte45O3abOXMzE3L7xDBg"
doc.search('img').map{ |img| img['src'] } 
doc.search('img').map{ |img| img['src'] }.each do |src|
  # do something with src if any are found.
end
doc.search('img').map{ |img| img['src'] }.compact.each do |src|
  # do something with src if any are found.
end
src = doc.at('img') && doc.at('img')['src']
doc = Nokogiri::HTML(<<EOT)
<html><body><p>foo</p>
<img src="blah">
<p>bar</p></body></html>
EOT
src = doc.at('img') && doc.at('img')['src']
=> "blah"
doc = Nokogiri::HTML(<<EOT)
<html><body><p>foo</p>
<img>
<p>bar</p></body></html>
EOT
src = doc.at('img') && doc.at('img')['src']
=> nil
doc = Nokogiri::HTML(<<EOT)
<html><body><p>foo</p>
<p>bar</p></body></html>
EOT
src = doc.at('img') && doc.at('img')['src']
=> nil
if doc.at('img')
  puts doc.at('img')['src']
end
if not doc.at('img').nil?
  puts doc.at('img')['src']
end
if (img = doc.at('img'))
  puts img['src']
end
img = doc.at('img')
if (img)
  puts img['src']
end

it fixes the issue After throwing the jars through a decompiler, it turns out the android.jar within the SDK is merely an empty shell so that IDEs such as Eclipse and IntelliJ can use a smaller jar to help with auto-complete. The code is fine but I'll need to inspect complete jars. I've found a Github repo that hosts these complete jars: https://github.com/Sable/android-platforms, if anyone is interested.

should help you out Spring can't inject anything in an instance that you create yourself with new or via reflection.
One of the ways to do what you want would be to request the beans from the application context, something along the following lines:
code :

@Autowired 
private ApplicationContext applicationContext;

public void createUser(Class<?> beanClass) {
    ILogic logic = applicationContext.getBean(beanClass);
    logic.saveUser();
}
