java - Multiple SessionAttributes into modelmap -


i pretty new spring, sorry if question may appear rather easy or obvious, trying answer bus wasn't able find it. question how use multiple sessionattributes , them map in 1 method?

i.e. have @controller uses sessionattributes:

@controller @sessionattributes({"name", "lastname", "birthdate"}) public class searchcontroller {      @requestmapping(value = "/your-relatives")     public string findrelatives(modelmap model) {         string name = (string) model.get("name");         string lastname = (string) model.get("lastname");         string birthdate = (string) model.get("birthdate");         if (name.equals("john") && lastname.equals("johnny")) {             return "yes";         }         return "no";     }  }

but when trying return "yes" in case when if true, error - there unexpected error (type=internal server error, status=500). no message available

it works when using 1 of attributes.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
