To verify the possibility it's HSQLDB problem I migrated to MySQL and I have same problem still. I just replaced dataSource configuration.
<bean>
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/person" />
<property name="username" value="root" />
<property name="password" value="pass" />
</bean>

I changed my configuration completely. The test and the goal is the same. When I wrote I changed my configuration, that means persistence.xml and applicationContext.xml (service, entity and repository are the same).
persistence.xml

Configure SpringDataJpa for java SE

I am wondering is it possible to configure SpringDataJpa to be used in javaSE, without spring boot.
I have seen some examples with xml configurations, for spring framework 4, but sadly i did not manage to make them work with spring framework 5.
And would it be possible to do that with properties configuration instead of .xml configurations.
When i tryed to use what #majid suggested, i get following error
Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [App]; nested exception is java.io.FileNotFoundException: class path resource [org/springframework/web/servlet/config/annotation/WebMvcConfigurer.class] cannot be opened because it does not exist

can you share your code; my hunch is you might be missing EnableJpaRepositories annotation.
Here is a quick sample:
App.java
#Configuration
#ComponentScan
#EnableJpaRepositories
public class App {
public static void main(String[] args) {
ApplicationContext ctx = new AnnotationConfigApplicationContext(App.class);
PersonService service = ctx.getBean(PersonService.class);
Person p = new Person("Raphael");
service.savePerson(p);
}
#Bean
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).build();
}
#Bean
public EntityManagerFactory entityManagerFactory() {
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(adapter);
factory.setPackagesToScan("com.demo.spring");
factory.setDataSource(dataSource());
factory.afterPropertiesSet();
return factory.getObject();
}
#Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory());
return txManager;
}
}
PersonRepo.java

private final PersonRepo personRepo;
public PersonService(PersonRepo personRepo) {
this.personRepo = personRepo;
}
public Person savePerson(Person p){

}
}

Hibernate don't persist in database

I'm new in using spring mvc and this is my first application , so I Followed a tutorial and I have a problem . When I run the server(Tomcat ) , hibernate don't persist or add table in mydatabase , when I drop the schema It cause a warning :
WARN: HHH000342: Could not obtain connection to query metadata : Cannot create PoolableConnectionFactory (Unknown database 'tests')
So I understand that there is no problem with the connection with the database .

You should check your dependencies. One problem is your spring-test dependency: it has an old incompatible version and it is not in scope test!
The ResourceEditorchanged between 2.5 and 4.2, the old constructor ResourceEditor(ResourceLoader) is no longer available but instead ResourceEditor(ResourceLoader,PropertyResolver).
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>4.2.5.RELEASE</version>
<scope>test</scope>
</dependency>
In your current setup I would assume you will have two versions of Spring framework (2.5 and 4.2.5) in your dependencies. Have a look using mvn dependency:tree before and after changing the spring-test dependency above.
If you have a doupt on your dependecies, I recommand to build a web project skeleton from https://start.spring.io/, import it to your workspace and check the Dependency Hiearchy tab of your pom.xml.
See the example: inputs to generate a spring mvc 4.2.5 tomcat 7 project test, hibernate... are included
The configs, even your web.xml are initialized by annotations. you can avoid the spring-servlet by initializing through annotation,
Exmanple Hibernate:
#Configuration
#EnableTransactionManagement
#ComponentScan({ "com.yourpackage.configuration" })
#PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {``
#Autowired
private Environment environment;
#Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(new String[] { "com.yourpackage.model" });
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
return dataSource;
}
private Properties hibernateProperties() {
Properties properties = new Properties();
properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
return properties;
}
#Bean
#Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(s);
return txManager;
}
}
For the viewResolver:
#Configuration
#ComponentScan(basePackages="com.yourpackage")
#EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{
#Bean
public ViewResolver getViewResolver(){
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
}
Use the Dependency Hiearchy as a reference to be sure you're not missing any dependency.
For tomcat you can omit the dependecies since you have your localown server.

Answer to your question
From effective Spring 2.5.x versions, have a concept of stereotyped Annotations you have to mark to your classes with these annotations to make it eligible for component scanning.
In your case you have mark your DAOImpl class with #Repository annotation like this given below.
#Repository
public class StudentHibernateDaoImpl implements StudentDAO {
Change your component scan tag as
<context:component-scan
base-package="edu.java.spring.controller,yourPackage.StudentHibernateDaoImpl"/> >
Here is an example which will resolve your issue.

Autowired JpaRepository is always null

I am configuring my JPA2 + Spring project and trying to use JPARepositories but I seem to be getting Null Pointer Exception on the autowired repository object. Please look at the code and help me identify what I am missing.

I was having trouble due to the entity not having any column "ID" (its SchoolID) and the repository had a method findByID which was throwing error.
While creating entityManagerFactory you need to specify your domain classes.
Add the following property in your configuration :
<property name="packagesToScan" value="com.abc.model"/>
In the stacktrace that you have pasted here, it says its not able to map/recognize the School class. Once you include the above property it should work
