Servlet中如何将json对象转化为Java中的自定义对象

前段ajax

$("#form1").submit(function() {var cname = $("input[name=cname]").val();var sup_company = $("select[name=select]").val();var ctype = $("input[name=ctype]").val();if(ctype=='国企'){ctype=1;}else{ctype=0;}var cadress = $("input[name=cadress]").val();var ctel = $("input[name=ctel]").val();var curl = $("input[name=curl]").val();$.ajax({url : "companyServlet?method=addCompany",type : "POST",contentType : "application/json;charset=utf-8",data : JSON.stringify({cname : cname,sup_company : sup_company,ctype : ctype,cadress : cadress,ctel : ctel,curl : curl,status:"1"}),success:function(data){if(data!=null){var datas=JSON.parse(data);if(data>0){alert("添加成功");}}},dataType:"json"});return false;});

后台servlet

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();}

后台需要的jar包有fastjson-1.1.32.jar，gson-2.1.jar

这样就可以将json对象转化自定义对象了
