示例1: getCurrentEnvironment
import freemarker.core.Environment; //導入方法依賴的package包/類
/**
* SCIPIO: Returns the Freemarker environment associated with current thread, or null
* if no rendering.
* <em>All transforms should use this call instead of <code>Environment.getCurrentEnvironment</code> directly!</em>
* <p>
* <strong>IMPORTANT</strong>: This exists as a workaround for quirks in Freemarker/Ofbiz rendering.
* Normally calling <code>Environment.getCurrentEnvironment</code> should be enough,
* but Ofbiz macro renderer uses <code>Environment.include</code> to render macros as opposed to
* <code>Environment.process</code>, and in those cases the calls return null and inevitable crash.
* So a patch to the renderer is required so the environment is accessible from macros, and
* all transforms must use this method. This method uses a second local source for Environment.
* <p>
* <em>2015-12-15</em>: we now give our local source environment priority over the Freemarker source
* because of problems rendering nested screens (otherwise may inadvertently return the wrong env).
* Really the Freemarker one should have priority, but this order prevents more problems in practice
* at current time (there is rarely/never a subscreen call done from the templates included
* by #includeTemplate method below).
* <p>
* On top, an extra fix is added to {@link #renderTemplate(Template, Map, Appendable)} to
* try to make it so - as much as possible - at most one of threadEnv OR the Freemarker-saved env
* is non-null at any given time. We cannot guarantee this but this should cover most cases in Ofbiz.
*
* @see #includeTemplate
* @see #renderTemplate(Template, Map, Appendable)
