public class BindingResultSerializer
extends com.fasterxml.jackson.databind.JsonSerializer<org.springframework.validation.BindingResult>

Jackson Serializer which generates a tree with binding and validation property errors stored on a BindingResult object.

Error messages will be DefaultMessageSourceResolvable.getDefaultMessage() so, it is already translated to (current request) language (or supposed to).

JSON generated for List binding errors:

   { 
     OBJECT_INDEX : { FIELD1_NAME : FIELD_ERROR_MSG, FIELD2_NAME : FIELD_ERROR_MSG, ...}, 
     OBJECT_INDEX2 : { FIELD1_NAME : FIELD_ERROR_MSG, 
         FIELD_OBJECT_NAME : { SUBOBJECT_FIELD: FIELD_ERROR_MSG, ... }
         FIELD_LIST_NAME: {
              OBJECT_FIELD_ITEM_INDEX : {ITEM_LIST_FIELD: FIELD_ERROR_MSG, ... },
              OBJECT_FIELD_ITEM_INDEX2 : {ITEM_LIST_FIELD: FIELD_ERROR_MSG, ... },
         },
         ...
     },
     ... 
   }
 

JSON for object binding errors:

 { FIELD1_NAME : FIELD_ERROR_MSG, 
      FIELD_OBJECT_NAME : { SUBOBJECT_FIELD: FIELD_ERROR_MSG, ... }
      FIELD_LIST_NAME: {
              OBJECT_FIELD_ITEM_INDEX : {ITEM_LIST_FIELD: FIELD_ERROR_MSG, ... },
              OBJECT_FIELD_ITEM_INDEX2 : {ITEM_LIST_FIELD: FIELD_ERROR_MSG, ... },
      },
      ...
 }
