Answer 1

OK、問題がありますconditionはです。の予約語はhereで入手できます（またはウェブサイトから別のバージョンを入手できます）。

経験的には、org.hibernate.exception.SQLGrammarExceptionを取得した場合は、予約語に問題があることがあります。

もう1つのヒントは、SQLを表示し、データベースで直接SQLを実行しようとすることです、それはSQLの問題を見つけることがより簡単になります。

春の起動時にspring.jpa.show-sql=trueを使用すると、休止状態のSQLを表示できます。

Answer 2

条件はMySQLでは予約語なので、エラーです。

変数をアプリケーションのモデルでshipCondtionに変更します。

は、私はあなたにもフライウェイ・マイグレーション・スクリプトを作成しているだろうと推測：

create table shipwreck(
    `id` int(10) NOT NULL AUTO_INCREMENT, 
    `name` varchar(255), 
    `description` varchar(255), 
    `ship_condition` varchar(255), 
    `depth` int(10), 
    `latitude` double(17,4), 
    `longitude` double(17,4), 
    `year_discovered` int(4), 
    PRIMARY KEY(id) 
); 

これは現在正常に動作する必要があります。

あなたがapplication.propertiesにMySQLDialectを定義する必要はありません：

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
