// 读取模板内容，模板由liferay-layout-templates.xml文件定义.
String content = LayoutTemplateLocalUtil.getContent(

下面是一个一列的模板:
＜div id="layout-content-outer-decoration"＞
＜div id="layout-content-inner-decoration"＞
＜div id="layout-content-container"＞
$processor.processColumn("column-1")
＜/div＞
＜/div＞
＜/div＞
// 处理模板
portlet.layoutconfiguration.util.RuntimePortletUtil.processTemplate(
application, pageContext, request, response, content);
// 注入模板处理程序
TemplateProcessor processor = new TemplateProcessor(ctx, req, res, portletId);
VelocityContext context = new VelocityContext();
context.put("processor", processor);
// 处理模板
Velocity.evaluate(context, pageContext.getOut(),
RuntimePortletUtil.class.getName(), content);
