剛剛寫了一個返回Map的方法，後面報了一堆錯誤：

查找了一下；原來是方法寫得有問題，寫成了死循環了，自己put自己進去了。貼上代碼記錄一下

@RequestMapping(value = "/getCompanySelectData",method = RequestMethod.POST)
	@ResponseBody
	public Map<String, Object> getCompanySelectData(HttpServletRequest request, HttpServletResponse response){
		Map<String, Object> result = new HashMap<String, Object>();
		result = companyService.getCompanySelectData();
		result.put("result", result);
		return result

就是這個代碼導致了這個錯誤，改成了直接返回就行了 
return  companyService.getCompanySelectData();
哎，代碼不注意又進了一個坑。。。繼續努力提高代碼質量了。
描述不對的歡迎指正！
