How to get all the key value pairs in modelMap object , inside spring controller itself , returned by modelAndView.getModel() in java spring framework

Question

Map modelMap = modelAndView.getModel();

I want to retrieve all the keys in the modelMap object , so that i can access each values , these values can be assigned to variables/objects created in the controller class itself

Answer 1

ModelMap subclasses LinkedHashMap which in turns extends HashMap

The generic type of ModelMap is fixed at Map<String, Object>

So you can iterate through the keys of a map as in HashMap, you can use keyset() or entryset()

for (Map.Entry<String, Object> entry : map.entrySet()) {
    System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}
