}
}
Controller

I know this question is already posted by someone but that does not solved my problem I'm still getting the following error ,could you please let me know what is wrong with this
Description:
Field shopRepository in com.test.assertmanagementdigital4.service.ShopService required a bean named 'entityManagerFactory' that could not be found.
Action:
Consider defining a bean named 'entityManagerFactory' in your configuration.
If I remove exclude auto configuration, I got following error
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

回答1:
If you dismiss auto configuration, then you should provide it by yourself.
See example:
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws URISyntaxException {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(your_datasource);
entityManagerFactoryBean.setPackagesToScan(package_to_scan);
//additional config of factory
return entityManagerFactoryBean;
}
@Bean(name = "transactionManager")
public PlatformTransactionManager jpaTransactionManager(EntityManagerFactory entityManagerFactory) throws URISyntaxException {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory);
return transactionManager;
}
回答2:
If you have this piece of code, just remove it.
public HibernateJpaSessionFactoryBean sessionFactory() {
return new HibernateJpaSessionFactoryBean();
}
回答3:
This problem is due to tomcat connection pooling. Try to add following dependency in your pom.xml
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-jdbc</artifactId>
</dependency>
It solved my problem.
