I'm working on a import module, where I'm reading from an excel file, fill the entities and save them.
Now my trouble is that I'm working with many entities and then i split the save on DB in three distinct methods.
This is my import method:
@Transactional(propagation = Propagation.REQUIRES_NEW)
private void readRowFromExcel(Row row){
for(Row row : sheet){
Customer customer = readCustomerFromExcel(row)
CustomerDeatails customerDetails = readCustomerDetailsFromExcel(row)
customerService.save(customer,customerDetails);
MyEntity myEntity = readMyEntityFromExcel(row);
myEntityService.save(myEntity)
}
}
This is the save method in the customer service
@Transactional(propagation = Propagation.REQUIRED)
public void save(Customer customer, CustomerDetails customerDetails){
customerRepository.save(customer);
customerDatailsRepository.save(customer);
}
This is the save method in the myEntity service:
@Transactional(propagation = Propagation.REQUIRED)
public void save(MyEntity myEntity){
myEntityRepository.save(myEntity)
}
Now my trouble is that if i get an exception on the following code line
MyEntity myEntity = readMyEntityFromExcel(row);
the entities customer and customerDetails are already persistent, while i should save only if everything works
My spring-context.xml
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${db.driverClass}" />
