Try with Spring
@Value("myValue")
String customerName;
And without spring, just assign value in declaration itself,
private String customerName="myValue";

I am using a CustomerDTO:
public class CustomerDTO {
private int customerId;
private String customerName;
private String customerAddress;
public int getCustomerId() {
return customerId;
}
public void setCustomerId(int customerId) {
this.customerId = customerId;
}
public String getCustomerName() {
return customerName;
}
public void setCustomerName(String customerName) {
this.customerName = customerName;
}
public String getCustomerAddress() {
return customerAddress;
}
public void setCustomerAddress(String customerAddress) {
this.customerAddress = customerAddress;
}
}
Then I am using CustomerDAO where I am fetching customer based on the customerId
public class CustomerDAO {
private CustomerDTO customer;
public void setCustomer(CustomerDTO customer) {
this.customer = customer;
}
public CustomerDTO getCustomer(int customerId){
try{
if("you get customer based on customer id") then "return the customer";
}catch(Exception ex){
return new CustomerDTO();
//some other work
}
}
}
Now this code new CustomerDTO();
in CustomerDAO is giving null
when I am trying to access new CustomerDTO().getCustomerName()
. I am thinking about initializing the field with default values.
How can I achieve this with/without Spring framework?
