Spring JPA java.lang.IllegalStateException：{classpath *：META-INF/persistence.xml}から解析された永続ユニットがありません

Question

私はSpring JPAの問題に直面しています。私はNO XMLでjava設定を行っています。

私は "java.lang.IllegalStateException：から解析されない永続性ユニット{クラスパス*：META-INF/persistence.xmlの}" 取得しています以下は

は自分のアプリケーションの設定クラスです。

ありがとうございます。

Answer 1

LocalContainerEntityManagerFactoryBeanは、@Entityクラスの場所を知る必要があります。

だから特性の下にそれを修正する必要が追加：http://stackoverflow.com/（[{META-INF/persistence.xmlのクラスパス\ *}から解析なし永続ユニット]の

localContainerEntityManagerFactoryBean.setPackagesToScan("path.to.your.entities"); 
localContainerEntityManagerFactoryBean.setPersistenceUnitName("name");
