FreeMarker中文乱码的问题。

1、在开发环境生产无乱码，打包后在生产环境出现乱码
直接上代码：修改前代码

 TemplateEngine engine = TemplateUtil.createEngine(new TemplateConfig(properties.getPath().getPath(), TemplateConfig.ResourceMode.FILE));
 ...
 private static void genFile(File file, Template template, Map<String, Object> map) throws IOException {
        // 生成目标文件
        Writer writer = null;
        try {
            FileUtil.touch(file);
             writer = new FileWriter(file);
             template.render(map, writer); 

        } catch (TemplateException | IOException e) {
            throw new RuntimeException(e);
        } finally {
            assert writer != null;
            writer.close();
        }
    }

修改后代码：

 Charset charset =  Charset.forName("UTF-8");
                TemplateEngine engine = TemplateUtil.createEngine(new TemplateConfig(charset,properties.getPath().getPath(), TemplateConfig.ResourceMode.FILE));
  ...
               
private static void genFile(File file, Template template, Map<String, Object> map) throws IOException {
        // 生成目标文件
        Writer writer = null;
        try {
            FileUtil.touch(file);
            //  writer = new FileWriter(file);
            // template.render(map, writer);
             writer = new PrintWriter(file,"UTF-8");
             template.render(map, writer);

        } catch (TemplateException | IOException e) {
            throw new RuntimeException(e);
        } finally {
            assert writer != null;
            writer.close();
        }
    }
