异步操作集合传值需要把集合封装成Json,然后传到前端,需要用到一个转Json的gson-2.3.1.jar包
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
response.setContentType("application/json");
String id = request.getParameter("zid");
int zid = Integer.parseInt(id);
Type_ser t= new Type_ser();
List<Type> chakan = t.chakantype(zid);
Gson g = new Gson();
String ty = g.toJson(chakan);
PrintWriter out = response.getWriter();
out.write(ty);
out.close();
}
