Employee emp = manager.getEmpl();
System.out.println("Employee found using HQL" + "\n"
+ "\to_id=" + emp.getId());
}
public void createEmp(TestManager manager) {
manager.createEmpl();
}
public static void main(String[] args) {
Test client = new Test();
Session session = client.openSession();
TestManager manager = new TestManager(session);
client.createEmp(manager);
client.testFindByHQL(manager);
session.close();
}
}
The Test.java main class file is created.
Implementing the Business Logic
The business logic for the EmpIoyeeInfo application is implemented in the TestManager.java
class file. To do so, complete the following steps:
1.
Create the TestManager.java class file in the com.hp.imp package, as explained in
“Creating the Employee.java Class File” (page 204) .
2. Add the method to perform an insert operation on the database using Hibernate.
3. Add the method to perform a select operation on the database using the HQL.
The TestManager.java class must appear as:
package com.hp.imp;
import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;
import com.hp.domain.Employee;
public class TestManager {
private Session session = null;
private Transaction tx = null;
public TestManager(Session session) {
if (session == null)
throw new RuntimeException(
"Invalid session object. Cannot instantiate the EmpManager");
this.session = session;
}
public Employee getEmpl() {
System.out.println(System.currentTimeMillis());
List l = session.createQuery("from Employee").list();
java.util.Iterator emps = l.iterator();
