public class FreemakerUtil {
    private static FreemakerUtil util;
    private static Configuration cfg;
    private FreemakerUtil(){
    }
    //做成单例模式
    public synchronized static FreemakerUtil getInstance(String pname){
        if(util==null){
            cfg = new Configuration();
            cfg.setClassForTemplateLoading(FreemakerUtil.class,pname);
            cfg.setDefaultEncoding("UTF-8");
            util=new FreemakerUtil();
        }
        return util;
    }
    //获取模版
    public Template getTemplate(String fname){
         try {
             return cfg.getTemplate(fname);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
    //控制台输出
    public void print(Map<String,Object> map,String fname){
        try {
            getTemplate(fname).process(map,new PrintWriter(System.out));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    //输出到指定位置
    public void fprint(Map<String,Object> map,String fname,String outpath){
