@Override    public String execute() throws Exception {        List
     
       find = echartsService.find();        Gson g = new Gson();        String list = g.toJson(find);        ServletActionContext.getResponse().setCharacterEncoding("UTF-8");        ServletActionContext.getResponse().getWriter().write(list);        System.out.println(list);        return NONE;    }
