关于使用JSONArray.fromObject()方法和引入net.sf.json包所需要的jar包支持

/**
	 * 跳转到全市总体概览
	 * @return
	 */
	@GetMapping("all")
	public String all (Model model) {
		Calendar cal = Calendar.getInstance();
		//当前年的前一年
		int year = cal.get(Calendar.YEAR) - 1;
		model.addAttribute("maxYear",year);
		model.addAttribute("minYear",minYear);
		model.addAttribute("title","全市"+year+"年主要经济指标运行情况");
		model.addAttribute("thisObj","all_id");
		List<Economicdatayear> list = eyService.GethistoricalTrendallTimeLine("合肥");
		JSONArray yearlist = JSONArray.fromObject(list);
		model.addAttribute("yearlist",yearlist);
		return "page/report6";
	}

Spring Boot用Model传list值到页面，需要先转换一下

前端js接收直接用var yearlist=[[${yearlist}]];
