私は春のデータの例を書いています。これは私のspring.xmlです

そして、これらは私のpom.xmlの依存関係です

persistence.xmlを使用していません。私は次の例外を取得しています

コードの何が問題なのか、依存関係とバージョンが正しいのか、あるいは、Spring 3.2にはpersistance.xmlが必要な場合は、何を含めるべきなのか.
このエラーは、JPA 1 APIが取り込まれたために発生しますが、メソッド getValidationMode はJPA 2以降にのみ存在します。
フォローする代わりに
<dependency>
<groupId>javax.persistence</groupId>
<artifactId>persistence-api</artifactId>
<version>1.0.2</version>
</dependency>
たとえば、Hibernateが提供するものを使用できます。
<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>
