SpringBoot getWriter() has already been called for this response

Why can I only use response.getOutputStream() in a project, when I use response.getWriter(), it always throws exception, but I can use response.getWriter() in a old project, and after i used this outputstream, i can not close it, because if i close it, my controller can not response anything, i think this is to terrible
