Question

detached entity passed to persist

Asked by: karanw

I using spring annotation.
I am getting following exception when I want to insert employee into database.
javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist:..Employee.

If we insert one employee it works,
How to insert multiple employees?

//In main method
for(int i=20; i<25;i++){
			 Employee emp= new Employee();
			 emp.setCId(i);
			 emp.setId(i);
			 emp.setSsn("ssn"+i);
			 Company company = new Company();
			 company.setCompanyId(i);
			 company.setCompanyName("companyname "+i);
					
			 emp.setCompany(company);
			 emp.setName("Karan "+i);
			 empDao.insertEmployee(emp);
			 
		 }
In dao.
@Transactional
	public void insertEmployee(Employee emp) {
		em.persist(emp.getCompany());
		em.persist(emp);
		em.clear();
 
	}
