**一 代码位置**

**二 开发语言字符编码**

1 HTML字符编码（index.html）

2 freemark字符编码（index.htl）

3 HttpResponse字符编码（com/imooc/controller/interceptor/OneInterceptor.java）

public void returnErrorResponse(HttpServletResponse response, IMoocJSONResult result)
          throws IOException, UnsupportedEncodingException {
       OutputStream out=null;
       try{
           response.setCharacterEncoding("utf-8");
           response.setContentType("text/json");
           out = response.getOutputStream();
           out.write(JsonUtils.objectToJson(result).getBytes("utf-8"));
           out.flush();
       } finally{
           if(out!=null){
               out.close();
           }
       }
    }

4 返回内容字符编码设定方法（com/imooc/controller/interceptor/TwoInterceptor.java）

public void returnErrorResponse(HttpServletResponse response, IMoocJSONResult result) throws IOException, UnsupportedEncodingException {
       OutputStream out=null;
       try{
           response.setCharacterEncoding("utf-8");
           response.setContentType("text/json");
           out = response.getOutputStream();
           out.write(JsonUtils.objectToJson(result).getBytes("utf-8"));
           out.flush();
       } finally{
           if(out!=null){
               out.close();
           }
       }
    }

**三 开发环境字符编码**
