SpringBootでtime型の値を受け取ろうとしてBindExceptionが発生する

Question

前提・実現したいこと

SpringBootにて、input type ="time"で入力した値をTime型で受け取ろうとしているのですが、
BindExceptionが発生しています。

StringからTimeに変換できない為に入力が受け付けられていないようですが、
特別な実装などが必要なのでしょうか？

またそれはどのようなものでしょうか？

秒も必要とか
あるかもしれません

Answer 1

java.sql.Time を変換するConverterは用意されていないようです。

https://docs.spring.io/spring-framework/docs/4.2.0.RC2_to_4.2.0.RC3/Spring%20Framework%204.2.0.RC3/index.html?org/springframework/core/convert/support/package-summary.html

Converter I/Fを自分で実装するか、
Time型ではなくString型で受けた後、Time型に自分で直すのが良いでしょう。

回答ありがとうございます。
Converterがないのですね。後者のやりかたでやってみます。
