jpa mysqlテーブルが存在しません。autoGenerateが機能しません。

Question

データベースにEmployeeエンティティを挿入しようとしています。私はJPAを使用しており、データベースはmysqlです。エンティティを挿入しようとすると、テーブルを作成する必要があります。テーブルを作成する必要はありません。 Entityは、注釈付きの名前を持つテーブルを自動的に作成します。以下の例外とコードを見つけてください。

    public Articles() {

    public Articles(Integer id) {

    } 


} 

Answer 1

私はEclipseLinkをして動作しますが、いくつかの例をチェックし、すべてが4つのプロパティそれぞれの下に言及していることが確認できていません時間：

<property name="eclipselink.ddl-generation" value="drop-and-create-tables"/> 
<property name="eclipselink.create-ddl-jdbc-file-name" value="createDDL_ddlGeneration.jdbc"/> 
<property name="eclipselink.drop-ddl-jdbc-file-name" value="dropDDL_ddlGeneration.jdbc"/> 
<property name="eclipselink.ddl-generation.output-mode" value="both"/> 

が原因である可能性がありますか？

問題はJPAでデータベースレベルであったとない私はあなたのデータベースではなく、JPA/EclipseLinkので問題を抱えている別のデータベースTHX
