spring boot getとpost要求、及びrequest bodyがjsonの時の処理です.

GET、POST方式で提する時、request header Conteen-Typeの値によって判断します.

    appication/x-wn-form-urlencoded、オプション(必須ではないので、この場合のデータ@Request Param、@ModelAttributeも処理できます.もちろん@Request Bodyも処理できます.)

    multiipad/form-dataでは処理できません.

    他のフォーマットは必須です.(他のフォーマットにはaplication/json、appication/xmlなどがあります.これらのフォーマットのデータは@Request Bodyを使って処理しなければなりません.)
