配置文件中设置编码格式

            conf = new Configuration();
            try {
                conf.setDirectoryForTemplateLoading(new File(LOCAL_STORAGE_DIR));
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            conf.setObjectWrapper(new DefaultObjectWrapper());
            conf.setDefaultEncoding("utf-8");

同时在输出文件时设置对应格式

out = new OutputStreamWriter(new FileOutputStream(new File()), "utf-8");
template.process(root, out);
out.flush();
