        @RequestParam(value="checkbookNumber", required=true) String checkbookNumber,
        @RequestParam(value="checkbookName", required=true) String checkbookName,
        @RequestParam(value="startNumber", required=true) long startNumber,

I have two table in one form ! I want to receive first table elements by name by specifying @RequestParam(value="startNumber", required=true) long startNumber; but second table elements in Map i.e Map map

How to receive some parameter with name and all other element in map ?

Answer 1

Create your own objects : 

public class MyMap {
    private String myObject1; // dont forget that these names should be same as @RequestParam values

    private Integer myObject2;

    //setters and getters. they are must!!

}

public class MyMap2 {
    private String my1;

    private Integer my2;

    //setters and getters. they are must!!

}

次に、このオブジェクトをコントローラー メソッドのパラメーターとして配置します。

@RequestMapping(value = "/Fin_AddCheckBook", method = RequestMethod.POST)
public @ResponseBody JsonResponse addCoaCategory(MyMap myMap, MyMap2 myMap2, BindingResult result) {
    if (!result.hasErrors()) {
        // work with myMap myMap2
    }
}
