spwrap: Stored Procedure call wrapper

spwrap is a Stored Procedure caller; simply execute stored procedure from java code.

Example:

public interface CustomerDAO {

    @StoredProc("create_customer")
    void createCustomer(@Param(VARCHAR) String firstName, @Param(VARCHAR) String lastName);

    @StoredProc("get_customer")
    Customer getCustomer(@Param(INTEGER) Integer id);   

    @StoredProc("list_customers")
    List<Customer> listCustomers();
}

public class Customer implements TypedOutputParamMapper<Customer>, ResultSetMapper<Customer> {

    private Integer id;
    private String firstName, lastName;

    public Customer() {
    }

    public Customer(Integer id, String firstName, String lastName) {
        super();
        this.id = id;
        this.firstName = firstName;
        this.lastName = lastName;
    }

    public Integer id() {
        return id;
    }

    public String firstName() {
        return firstName;
    }

    public String lastName() {
        return lastName;
    }

    @Override
    public Customer map(Result<?> result) {
        if (result.isResultSet()) {// for ResultSetMapper
            return new Customer(result.getInt(1), result.getString(2), result.getString(3));
        } else { // for TypedOutputParamMapper
            return new Customer(null, result.getString(1), result.getString(2));
        }
    }

    // for TypedOutputParamMapper
    @Override
    public List<Integer> getTypes() {
        return Arrays.asList(VARCHAR, VARCHAR);
    }
}

DAO dao = new DAO.Builder(dataSource).build();
CustomerDAO customerDao = dao.create(CustomerDAO.class);

customerDao.createCustomer("Abdullah", "Muhammad");
Customer abdullah = customerDao.getCustomer(0);
