Inject PersistenceContext from persistence.xml

Inject PersistenceContext from persistence.xml - java

I'm trying to use the PersistenceContext annotation to inject an entity manager but I get the following exception.
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'Foo' available
Then I did some research and in every example there's a bean in the configuration class with the same information that I have in my persistence.xml.
Are we supposed to be able to inject the entitymanager with only the persistence-unit name?
Here's my code
#Component
public class UnitOfWork {
#PersistenceContext(unitName="Foo")
private EntityManager entityManager;
}
#Configuration
#ComponentScan("com.foo.package")
public class Config {
}

You still need to define a LocalContainerEntityManagerFactory to have the EntityManagerFactory available in the application context.
Without one that wouldn't work, the LocalContainerEntityManagerFactory will use the persistence.xml (when present) to configure itself.

Based on your information, it need your check on your oracle jdbc connection first, especially for below part:
<!-- declare datasource -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#localhost:1521:orcl21"/>
<property name="username" value="c##gss_pos" />
<property name="password" value="sys" />
</bean>
You need ensure you can connect to your Oracle DB via the localhost:1521:orcl21 with proper user and password.

Can you also use the latest JDBC driver? You are using 11.2.0.4. Try using 21.5.0.0 or 19.14.0.0. Check out OTN page.

Invalid version of spring-jpa

In my project I have three model files- User, Appointment and Notification. There are three repository interfaces each implements CRUDRepository. Service and Controller class are also present. While executing the project i am getting two errors:
1. No spring Webinitializer detected on classpath.
2. exception while creating bean.
here is stack trace:

Many answers on stackoverflow suggested that error is due to invalid version of spring-jpa and spring data. I tried to change the version of spring, but did not help. Which version of spring and spring-jpa should I use? Do I need to add some other dependency?

Spring version - 4.3.8.RELEASE and spring data jpa version - 1.0.2.RELEASE combination worked for me.
If it is version issue then may be you can try this combination.

You have version mismatch problem with BeanUtils.findPropertyForMethod
The below dependency is causing the version problem which is referring to findPropertyForMethod which takes one parameter.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.6.4.RELEASE</version>
</dependency>
Consider changing the version to 2.0.3.RELEASE which would resolve the issue.

Hibernate 5.2.2: No Persistence provider for EntityManager

What has changed between Hibernate 5.1.1 and 5.2.2? If I use 5.2.2 I'll get an error message "No Persistence provider for EntityManager named pu". Exactly the same configuration works with 5.1.1. How should I change my code to get 5.2.2 to work?

The class org.hibernate.ejb.HibernatePersistence does not exist in the hibernate-release-5.2.2.Final.zip bundle file. That's why the provider can't be found, because the class can't (at the project library jars). Instead, I used the class org.hibernate.jpa.HibernatePersistenceProvider, which CAN be found at hibernate-core-5.2.2.Final.jar (that comes with hibernate-release-5.2.2.Final.zip bundle), by changing the provider at persistence.xml to <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>. Doing so, it worked fine! Hope the problem is only this.

I had the same error.
I changed version of
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
</dependency>
from 5.3.1.Final to 5.3.6.Final and error disappeared.

Sometimes simply forgetting to add the persistence.xml file to build path causes this problem. Follow the following steps:
Right click on persistence.xml file.
Click on Build Path
Add to build path
Then it should work.

Error in database connection

I have been working on a project, which is a simple Spring, Hibernate, JSF, MySQL integration; and I run it on Eclipse. The aim of the program is to add a Person(id, first name, last name, gender, age etc.) database on MySQLWorkbench and run it on server. I used Spring4, Hibernate4, Primefaces 5.0.2 and Eclipse Luna as tools.And I constructed the project as maven.
When I run the program on main, I want to see that a new Person is included in my table.
I used "GRANT ALL ON" and "FLUSH PRIVILEGES" commands for the user I have created, on terminal and received "Query OK" message.
Despite specifying username and password on necessary files, I cannot add a new record to my table.My Project structure is as follows:
And other files are:

System.out.println("CFG and hbm files loaded successfully.");//just to test
configuration.configure("hibernate.cfg.xml");
SessionFactory factory = configuration.buildSessionFactory(new StandardServiceRegistryBuilder().configure().build());
Session session = factory.openSession();
Transaction tx = session.getTransaction();
tx.begin();
System.out.println("Transaction began");//just to test
Person newPerson = new Person();
newPerson.setFirstName("aa");
newPerson.setLastName("bbb");
newPerson.setGender("Male");
newPerson.setAge(2);
session.save(newPerson);
session.flush();
tx.commit();
session.close();
System.out.println("Session closed");//just to test
}
}
Is there an extra step to achieve this database connection?
Or what is my mistake here?
Thanks for any help..

Probably your session is not getting flushed; might be a glitch in your configuration. It happens many a time for an instance if you have configured OpenSessionInView Filter it changes the default flush mode of your configuration. In the DAO layer check the flushMode session.getFlushMode()
The flush mode should not be NEVER or MANUAL
If the session is not getting flushed, you db will not be updated. You have to manually flush the session after your transaction by session.flush()
Also in the in configuration file just change the property to true from false & check <property name="connection.autocommit">true</property>

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Inject PersistenceContext from persistence.xml - java

You still need to define a LocalContainerEntityManagerFactory to have the EntityManagerFactory available in the application context. Without one that wouldn't work, the LocalContainerEntityManagerFactory will use the persistence.xml (when present) to configure itself.
