body: <p>In a Thymeleaf template, how can I get the value of a system environment variable?</p>
  
  <p>I thought perhaps <code>${@environment.getProperty('VariableName', 'DefaultVariableValue')}</code> would work...however; it seems to always return <code>DefaultVariableValue</code>, even when <code>VariableName</code> is defined in the environment.</p>
