java.lang.IllegalArgumentException: No PersistenceProvider specified in EntityManagerFactory configuration
Solution 1
Change the emf
bean configuration and add a new bean called jpaVendorAdapter
:
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="emf">
<property name="packagesToScan" value="com.medsoft.stadto.entity" />
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter"/>
<property name="persistenceUnitName" value="stadto"/>
<property name="jpaProperties">
<props>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
<bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true"/>
<property name="generateDdl" value="true"/>
<property name="databasePlatform" value="org.hibernate.dialect.PostgreSQLDialect"/>
</bean>
Also make sure you have a persistence.xml
in the META-INF
directory:
<?xml version="1.0"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
version="2.1">
<persistence-unit name="stadto">
//No need to specify the provider as we already have specified JPA vendor in applicationContext.xml
</persistence-unit>
</persistence>
Solution 2
It happens when you don't configure JpaVendorImplementation for JPA. The below Java bean definition for JPA EntityManager works for me:
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
DataSource dataSource) {
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(dataSource);
emf.setPackagesToScan(irdbConfig.getPathForPackagesToScan());
emf.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
emf.setJpaPropertyMap(irdbConfig.getAdditionalHibernateProperties());
return emf;
}
But the below one throws same exception you received:
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
DataSource dataSource) {
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(dataSource);
emf.setPackagesToScan(irdbConfig.getPathForPackagesToScan());
return emf;
}
Please notice the lines which are removed from the second code.

Jess almost 7 yearsIs there a way to do without using perssistence.xml ? Can you explain what his vendor adaptor does ?

mertaksu about 6 yearsThere is a way to do without using persistence.xml. You can create LocalContainerEntityManagerFactoryBean with hibernates jpa vendor adapter; @Bean public LocalContainerEntityManagerFactoryBean directoryManagerFactory() { HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter(); LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); return localContainerEntityManagerFactoryBean;}
