I cannot understand what is going wrong with my simple Spring MVC project with JPA repositories. Could you please give a hint.
Domain:
package com.test.app;
#Entity
#Table(name = "foo_table")
public class FooDomain {
#Id
#Column(name = "id", unique = true, nullable = false)
private Integer id;
#Column(name = "text", nullable = false)
private String text;
// getters & setters here...
}
Repository
package com.test.app;
#RepositoryDefinition(domainClass=FooDomain.class, idClass=Long.class)
public interface FooRepository extends CrudRepository<FooDomain, Long> {}
Controller
#Controller
public class HomeController {
#Autowired
private FooRepository fooRepository;
#RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
model.addAttribute("rowsNumber", fooRepository.count());
return "home";
}
}

I faced this issue, when I was using Hibernate 4 (SessionFactory for persistence way, instead of EntityManagers) with Spring Boot. Adding this got rid of the error. Perhaps helps someone.

The context is Java Spring MVC and Hibernate, in IntelliJ. For some reason, in the Spring MVC config file, "transaction-manager" is not recognized as a valid reference. See the red text below:
Any tips on how to resolve this?
Here is the full config file:

I am working on project with Spring mvc and i want to use jpa features as well.
I have an 3 entity classes, their corresponding repository interfaces. I have their autowired objects in common service class. However I am facing issues while creating bean for this service class object which is used in controller.
The 3 model class are User, Appointment and Notification.
The repository interface extends CRUDRepository interface.
Service class :
#Service
public class EHealthService
{
#Autowired
UserRepository uRepo;
#Autowired
AppointmentRepository aRepo;
#Autowired
NotificationRepository nRepo;
public void registerUser(User u)
{
uRepo.save(u);
}
public boolean login(User u)
{
if(uRepo.findByemail(u.getEmail())!=null)
return true;
else
return false;
}
public List<User> getDoctorList()
{
return uRepo.findByisdoctor(true);
}
// some more functions
}
Controller class:
#Controller
public class EHealthController
{
#Autowired
EHealthService eservice;
//Some code
}

It says the class is an interface.
What will be the bean for eservice object and to enable jpa in dispacter servel xml file?
Thank you.
If you are using spring xml based configuration then add below bean's to configuration file :
<bean id="entityManagerFactoryBean" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- This makes /META-INF/persistence.xml is no longer necessary -->
<property name="packagesToScan" value="com.howtodoinjava.demo.model" />
<!-- JpaVendorAdapter implementation for Hibernate EntityManager.
Exposes Hibernate's persistence provider and EntityManager extension interface -->
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">validate</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
</props>
</property>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/test" />
<property name="username" value="root" />
<property name="password" value="password" />
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactoryBean" />
Register component scanning by adding this binding annotation in xml file :
<context:component-scan base-package="com.mycompany.projectname.demo" />
If your project is spring mvc the add below binding annotation to xl file
<!-- This allow for dispatching requests to Controllers -->
<mvc:annotation-driven />
For declarative transaction management add below piece in xml file.
<tx:annotation-driven />
Basically you no need to add service bean in xml configuration file if you are enabled component scanning feature in spring.
Add required dependencies to integrate jpa with spring.

Hi I'm having a problem setting up hibernate on spring. I was able to make it work but it creates a lot of session on the database. From What i have notice it creates session for every bean on my spring.xml. Since I have 6 beans declared I also have 6 session on the database on application start Here is my code

You need to use transactionManager to manage session for you.
Add the following lines of code to your spring.xml
....
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="yourSessionFactory" />
</bean>
....
Then you have to annotate your service impl classes #Transactional("transactionManager") to make transactionManager managing transactions through session
#Transactional("transactionManager")
public class PServiceImpl implements PServiceImpl{
....
Just an advice you can replace XML config for the DI by annotations to make it easy
in spring.xml, remove all your beans declarations (xxservice and xxxdao) and replace them by: <context:component-scan base-package="put here the package where your services and daos are lacated" />
your service must look like this :
#Service
#Transactional("transactionManager")
public class XXXServiceImpl implements XXXService{
#Autowired
private XXXDAO xxxDAO;
...
}
And your dao must look like :
#Repository
public class XXXDAOImpl implements XXXDAO {
#Autowired
private SessionFactory sessionFactory;
...
}
One more thing, add the tx schema in your file config header, your spring.xml should look like this :
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

My DAO Call:
#Component
public class SettingsDaoImpl {
#Autowired
#PersistenceContext
public EntityManager em;
public SettingsDaoImpl() {
super();
}
#Transactional
public Long save(Settings sr)
{
em.persist(sr);
return sr.getId();
}
As you can see I added the second database in my application. However, I do not know how to properly call it inside my SettingsDaoImpl?
Any recommendations how to implement this in my current architecture.
You need to create different entity manager for each datasource and in the code you need to define unitName property of #PersistenceContext to inject particular entity manager.
I would like set my Hibernate/JPA FlushMode to COMMIT, but in configuration file (applicationContenxt.xml is one of my files), i have a entityManager in my DAO, but i don't know how to set this in configuration file.
So, this is my applicationContext.xml

<bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect">

SOLUTION:
After a lot of research, i found a solution. I setted the FlushMode in #PersistenceContext in my BasicDAO class. Look:
#PersistenceContext(type = javax.persistence.PersistenceContextType.EXTENDED,
properties = #PersistenceProperty(name="org.hibernate.flushMode", value="COMMIT"))
protected EntityManager entityManager;
This works fine. I removed all #Transactional annotation from my "find" functions, because with #Transactional the "COMMIT" are fired and flush too.
