Is it a better way to get the inserted id in Hibernate?

Question

I am using Hibernate 3.0 and Struts. I am using @GeneratedValue for the id generation.

I have one customer screen when I save the customer details I want to move to the next screen with the newly inserted customerId because based on that ID only I will save the second page details

for that I am using like

someDAO.save(customer);
customerId = customer.getCustomerId();

I get the customer object value after save and using Struts 2 redirectAction I forward the customerId to second page, it is working fine but I am getting warn on my console

Caught OgnlException while setting property 'applicationId' on type 'org.apache.struts2.dispatcher.ServletActionRedirectResult'.

Answer 1

Best way You can ignore this,

However redirectAction uses the ActionMapper provided by the ActionMapperFactory to redirect the browser to a URL that invokes the specified action and (optional) namespace. The OGNL try to set the map html elements with values specified on source page and push these values in the valuestack. sometimes OGNL attempts to map values with setters which is specified in the action class with the source -page and failed to set the values and resulted in warning.

you can try explicitly assigning the param's to suppress warning :

<result name="showReportResult" type="redirectAction">
     <param name="applicationId">${applicationId}</param>
 </result>

Answer 2

The exception says that

Exception thrown if a property is attempted to be extracted from an object that does not have such a property

This means that you need to the Java bean property applicationId. Putting getters and setters on the field should solve the issue.

About better way to insert the id with hibernate use

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name = "id", nullable = false)
public Long getId() {
    return id;
}
