Apache FreeMarker

package com.jcms.taglib;

import java.io.IOException;
import java.io.Writer;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import freemarker.core.Environment;
import freemarker.template.TemplateDirectiveBody;
import freemarker.template.TemplateDirectiveModel;
import freemarker.template.TemplateException;
import freemarker.template.TemplateModel;

public class SqlDirectiveModel implements TemplateDirectiveModel 
{
	
	public void execute(Environment env, Map map, TemplateModel[] model,
			TemplateDirectiveBody body) throws TemplateException, IOException
	{
			body.render(env.getOut());
	}
}

<@sql return='v'>
你好
<#if v??>
${v}
</#if>
</@sql>
