org.hibernate.tool.schema.spi.CommandAcceptanceException:JDBCステートメントを介したDDLの実行エラー

私は本当に、stackoverflowで見つけたすべての質問を検索する手助けが必要ですが、何も機能しません。私はこれまでHibernateを使用したことがなく、何が問題なのかわかりません。テーブルを生成しましたが、挿入すると問題が発生します。

私はこのエラーを受け取ります:

方言エンジンの問題をmysql方言に変更すると、次の行に追加されます。

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect

SprintBoot 2.xでこの例外があり、方言を変更することで解決しました。 org.hibernate.tool.schema.spi.CommandAcceptanceException:JDBCステートメントによるDDLの実行エラー

私は同じ問題に直面しており、この例外から私を引き出すものは、以下の手順で説明されています-

  1. かわった <hibernate-configuration name="">タグ<hibernate-configuration> hibernate.cfg.xmlファイル内。
  2. 接続タグは常にlocalhost、port、スキーマ名またはデータベース名とともに-<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/protein_tracker</property>

そして、これらは例外なく実行を行います、それは私にとってはうまくいきます、それがあなたにも少し役立つことを願っています!

正確には、mysqlデータベースに対してスクリプト(DDL)を実行するときに、Hibernate JDBCドライバーに問題があります。

エラーには、適切な説明があります。SQLクエリに「外部キー制約を追加できません」というエラーが発生します。

複数のテーブルがマップされているので、1つずつ移動して、エラーが発生しているテーブル生成を確認することをお勧めします。これにより、発生している制約エラーを理解できます。

指定したエラーログは、dbエンジンの実行に関する他の統計に置き換わる統計テーブルエラーを示しているため、関係ありません。

ありがとう
