Accidental complexity

Wrong level of abstraction

Can we solve them with models?

Demo

@SuppressWarnings("serial")@Entity@Table(name = "CUSTOMER_INFO")public class CustomerInfo implements Serializable {

@Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "idSeq") @SequenceGenerator(name = "idSeq", sequenceName = "CUST_SEQ", allocationSize = 1) @Column(name = "CUST_ID", nullable = false) private String customerId;

public void setCustomerId(String customerId) { this.customerId = customerId; }

public String getCustomerId() { return customerId; }

@Column(name = "EMAIL", nullable = false, length = 128) private String emailAddress;

public String getEmailAddress() { return emailAddress; }

public void setEmailAddress(String emailAddress) { String oldValue = emailAddress; this.emailAddress = emailAddress; firePropertyChangedEvent("emailAddress", oldValue, this.emailAddress); }

entity CustomerInfo (id=CUST_ID, sequenceName=CUST_SEQ) { String emailAddress (notNull, length = 128)}
