@RequestMapping(value="/addUserJson")
public String addUserJson(User user,HttpServletRequest request,HttpServletResponse response){
String result = "{\"userName\":\""+ user.getUserName() +"\",\"age\":\" "+ user.getAge()+" \"}";
PrintWriter out = null;
response.setContentType("application/json");
try {
out = response.getWriter();
out.write(result);
} catch (IOException e) {
e.printStackTrace();
}
return "userManager";
}
