相比于@where，filter可以在runtime的时候customized条件
public enum AccountType {
DEBIT,
CREDIT
}
@Entity(name = "Client")
public static class Client {
@Id
private Long id;
private String name;
@OneToMany(mappedBy = "client")
@Filter(name="activeAccount", condition="active = :active")
private List<Account> accounts = new ArrayList<>( );
//Getters and setters omitted for brevity
}
@Entity(name = "Account")
@FilterDef(name="activeAccount", parameters=@ParamDef( name="active", type="boolean" ) )
@Filter(name="activeAccount", condition="active = :active")
public static class Account {
@Id
private Long id;
@ManyToOne
private Client client;
@Column(name = "account_type")
@Enumerated(EnumType.STRING)
private AccountType type;
private Double amount;
private Double rate;
private boolean active;
//Getters and setters omitted for brevity
}
