解决SpringMVC的GET请求中文乱码

进行转码

@RequestMapping("querySupplyToJSON")
	@ResponseBody
	public List<Supply> querySupplyByJson(Supply supply) throws UnsupportedEncodingException{
		String str = new String(supply.getGongyingshangname1().getBytes("ISO-8859-1"), "utf-8");
		System.out.println("====="+supply.getGongyingshangname1()+"===="+str);
		return supplyService.queryAll();
	}

控制台的结果，转码前和转码后的结果
