1. 需要jar freemarker-2.3.8.jar

2. demo 如下：

import java.io.File;import java.io.IOException;import java.io.StringWriter;import java.util.HashMap;import java.util.Map;import freemarker.core.Environment;import freemarker.template.Configuration;import freemarker.template.Template;import freemarker.template.TemplateExceptionHandler;public class Test {/**     * <一句话功能简述>     * <功能详细描述>     * @param map map     * @param fileName fileName     * @return 字符串流     * @see [类、类#方法、类#成员]     */    @SuppressWarnings("unchecked")    public static String buil(Map map, String fileName)    {        String url = Test.class.getResource("").getPath().replaceAll("%20", " ");        String path = url;        StringWriter out = new StringWriter();        try        {            Configuration configuration = new Configuration();            configuration.setDirectoryForTemplateLoading(new File(path));            Template template = configuration.getTemplate(fileName);            template.setTemplateExceptionHandler(TemplateExceptionHandler.IGNORE_HANDLER);            template.setEncoding("UTF-8");            template.setOutputEncoding("UTF-8");            Environment env = template.createProcessingEnvironment(map, out);            env.process();            out.flush();        }        catch (Exception e)        {        }        finally        {            try            {                out.close();            }            catch (IOException e)            {                e.printStackTrace();            }        }        return out.toString();    }public static void main(String[]arrgs){Map<String,String> map= new HashMap<String,String>();map.put("id", "test123456");System.out.println(buil(map,"test.ftl"));}}

test.ftl

<xml id ="${id}"></xml>
