I'm learning Spring. I created a spring mvc project. If i write these lines in root-context.xml:
<context:component-scan base-package="com.jaive.test.dao" />
<context:component-scan base-package="com.jaive.test.service" />
<import resource="data.xml" />
then i get HTTP Status 404. If not, everything works fine. I want to know about these lines and why this happenning. I use Apache Tomcat 7.
data.xml:

Presently I have a datasource configured using Hikari in my applicationContext.xml. I want to configure in the same xml file for a master/slave kind of datasource.
Also how do I establish a new entity manager factory in the same ?
My applicationContext.xml which is configured for 1 datasource(read as master) looks like:

How do I configure this xml for adding a slave datasource ?
specify url as described in mysql connector-j documentation
I have an application setup based on a previous configuration - which was 100% functional. Now I am using maven and am encountering an Error in my controller class which says i must configure Beans.xml.
I'm not sure exactly what this means, as I have my dispatcher-servlet.xml configured in the same way as the functional application.

Edit: Screenshot of error. Which occurs when using the #Transactional annotation.
I use Spring with Hibernate. I am using following configurations. When I try to save through Spring transaction, the record never commits.

MyControllerClass
#Transactional
#RequestMapping(...)
public String saveRecords(#ModelAttribute("orderObj") Order order){
for(Item item : order.getItems()){
itemDAO.save(item);
}
return "saveSuccess";
}
MyDAOClass
public void save(Item item){
session = sf.openSession();
session.save(item);
session.close();
}
The above #Transactional configuration not committing the record. But if I remove #Transactional from spring controller and use Hibernate transaction as below, the record commits.
public void save(Item item){
session = sf.openSession();
Transaction tx = session.beginTransaction();
session.persist(item);
tx.commit();
session.close();
}
This class commits the record.
I've gone through some forums and it's mentioned that #Transactional will take care of committing records. What mistake I am doing here? Can someone help?
Thanks in advance.
It worked after I have added <tx:annotation-driven /> annotation to my configuration xml & removed hibernate.current_session_context_class from hibernateSessionFactory bean. Given the changes below.

Then I have included org.springframework.transaction.annotation.Transactional annotation to all my service methods & removed all transactions from my DAO classes.
public void save(Item item){
//session = sf.openSession();
session.save(item);
//session.close();
}
Thanks all for your help.
Below is the EmployeeDaoImpl file which is injecting sessionFactory.
#Repository
public class EmployeeDaoImpl implements EmployeeDao {
#Autowired
private SessionFactory sessionFactory;
#Override
public void addEmployee(TestEmployee employee) {
this.sessionFactory.getCurrentSession().save(employee);
}
#SuppressWarnings("unchecked")
#Override
public List<TestEmployee> getAllEmployees() {
return this.sessionFactory.getCurrentSession().createQuery("from TestEmployee").list();
}
#Override
public void deleteEmployee(Integer employeeId) {
TestEmployee employee = (TestEmployee) sessionFactory.getCurrentSession().load(
TestEmployee.class, employeeId);
if (null != employee) {
this.sessionFactory.getCurrentSession().delete(employee);
}
}
}
Below is my employee-servlet file

I am getting An AnnotationConfiguration instance is required error. I have searched it on net but not able to solve this. I have the run configuration. I am using hibernate 3 and spring 3.1 JARS. Kindly help
daoin
<context:component-scan base-package="com.rights.controller" />
you seems like you forgot the package of your repository you should add it using :
<context:component-scan base-package="com.rights.controller com.rights.dao" />
in the configuration you posted, the class with annotation #Repository may not be post-processed by spring, if it package is not include in the component scan
I hope it may help you
