UnsupportedOperationException: приложение должно предоставить JDBC соединения JPA Hibernate Spring JDBC

Question

Когда я пытаюсь начать транзакцию

entityManager.getTransaction().begin(); 

в AbstractDao, я получаю

java.lang.UnsupportedOperationException: The application must supply JDBC connections 

Мой persistence.xml

<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" 
     version="2.0"> 
<persistence-unit name="pu" transaction-type="RESOURCE_LOCAL"> 
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
    <properties> 
     <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> 
     <property name="hibernate.hbm2ddl.auto" value = "create-drop"/> 
    </properties> 
</persistence-unit> 
</persistence> 

My hibernate.properties

jdbc.driverClassName=com.mysql.jdbc.Driver 
jdbc.url=jdbc:mysql://localhost:3306/ewp?createIfNotExist=true 
jdbc.username=root 
jdbc.password=root 
hibernate.dialect=org.hibernate.dialect.MySQLDialect 
hibernate.show_sql=true 
hibernate.format_sql=false 
hibernate.hbm2ddl.auto=create-drop 

EntityManagerFactory боб:

@Bean 
public EntityManagerFactory entityManagerFactory(){ 
    EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("pu"); 
    return entityManagerFactory; 
} 

EntityManager боб:

@Bean 
public EntityManager entityManager(){ 
    return entityManagerFactory.createEntityManager(); 
}

Из спящего режима site, ваши свойства называют взгляд неверным. Должно быть,

"hibernate.connection.driver_class" for JDBC driver class 
"hibernate.connection.url" for JDBC URL 
"hibernate.connection.username" for database user 
"hibernate.connection.password" for database user password
