获取json数据 名字一样就获取了
user
@RequestMapping("/addUser")
public String addUser(User user,HttpServletRequest request){
request.setAttribute("userName", user.getUserName());
request.setAttribute("age", user.getAge());
return "/userManager";
}
传递json数据
public void addUserJson(User user,HttpServletRequest request,HttpServletResponse response){
//{"username":"userName","age","age"}
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();
}
}
