protected void service(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		ServletInputStream inputStream = request.getInputStream();
		String json=IOUtils.toString(request.getInputStream());
		json=URLDecoder.decode(json,"utf-8");
		Gson gson=new Gson();
		Company company=gson.fromJson(json, Company.class);
		int re=companyService.addCompany(company);
		String data=JSON.toJSONString(re);
		response.getWriter().print(data);
		response.getWriter().flush();
	}
 

後臺需要的jar包有fastjson-1.1.32.jar，gson-2.1.jar

這樣就可以將json物件轉化自定義物件了
