Customer Management in Webui

Understanding Customer in Webui​

The Customer class represents a bank customer, including their personal and financial information. This class provides various methods to manage customer data, such as creating, editing, and deleting customer instances.

Customer Attributes​

The Customer class includes several attributes to store customer information. These attributes are:

  • customerNumber
  • sortcode
  • name
  • address
  • dob (date of birth)
  • creditScore
  • creditScoreReviewDate
  • editingCustomer

These attributes are defined in the Customer class to store customer information.

	private String customerNumber;

	private String sortcode;

	private String name;

	private String address;

	private Date dob;

	private String creditScore;

	private Date creditScoreReviewDate;

	private Boolean editingCustomer;

Creating a Customer​

To create a new customer, click on the 'Create customer' button on the landing page. This action will invoke the addToDB method to add the customer to the database.

Viewing Customer Details​

To view customer details, click the 'View customer details' button on the landing page. This will display all stored information about the customer.

Adding a Customer to the Database​

The addToDB method is used to add a new customer to the database. It creates a CustomerJSON object with the customer's details and sends a request to the CustomerResource to create the customer externally. If the response status is 201, it parses the response and updates the customer's details.

The addToDB method adds a customer to the database by creating a CustomerJSON object and sending a request to the CustomerResource.

	public String addToDB()
	{
		CustomerResource myCustomerResource = new CustomerResource();

		CustomerJSON myCustomerJSON = new CustomerJSON();

		myCustomerJSON.setCustomerAddress(this.getAddress());
		myCustomerJSON.setCustomerName(this.getName());
		myCustomerJSON.setDateOfBirth(this.getDob());
		myCustomerJSON.setSortCode(this.getSortcode());
		Response myCustomerResponse = myCustomerResource
				.createCustomerExternal(myCustomerJSON);

		String myCustomerString = null;
		JSONObject myCustomer = null;

		if (myCustomerResponse.getStatus() == 201)
		{
			myCustomerString = myCustomerResponse.getEntity().toString();
			try
			{

Updating Customer Information​

The updateThis method updates an existing customer's information in the database. It creates a CustomerJSON object with the updated details and sends a request to the CustomerResource to update the customer externally. If the response status is 200, it parses the response and updates the customer's details.

Deleting a Customer from the Database​

The deleteFromDB method deletes a customer from the database. It sends a request to the CustomerResource to delete the customer externally. If the response status is 200, it confirms the deletion.

The deleteFromDB method deletes a customer from the database by sending a request to the CustomerResource.

	public boolean deleteFromDB()
	{
		CustomerResource myCustomerResource = new CustomerResource();

		Response myCustomerResponse = myCustomerResource.deleteCustomerExternal(
				Long.parseLong(this.getCustomerNumber()));

		String myCustomerString = null;
		JSONObject myCustomer = null;

		if (myCustomerResponse.getStatus() == 200)
		{
			myCustomerString = myCustomerResponse.getEntity().toString();
			try
			{
				myCustomer = JSONObject.parse(myCustomerString);
			}
			catch (IOException e)
			{
				logger.log(Level.SEVERE, e::toString);

Checking if a Customer Exists in the Database​

The inDB method checks if a customer exists in the database. It sends a request to the CustomerResource to retrieve the customer details. If the response status is 200, it confirms the existence of the customer.

The inDB method checks if a customer exists in the database by sending a request to the CustomerResource.

	/**
	 * inDB
	 * 
	 * Checks if the customer is in the database
	 * 
	 * @return
	 */
	public boolean inDB()
	{
		CustomerResource myCustomerResource = new CustomerResource();

		Response myCustomerResponse = null;
		String myCustomerString = null;
		JSONObject myCustomer = null;

		myCustomerResponse = myCustomerResource
				.getCustomerExternal(Long.parseLong(this.customerNumber));
		if (myCustomerResponse.getStatus() == 200)
		{
			myCustomerString = myCustomerResponse.getEntity().toString();
			try

Displaying Customer Information​

The showInfo method displays all stored information about a customer, including their credit score if the customer is being edited.

The showInfo method displays all stored information about a customer.

	/**
	 * showInfo
	 * 
	 * Displays all the info stored about the customer Will show a credit score
	 * if the customer is being edited
	 * 
	 */
	public void showInfo()
	{

		if (Boolean.FALSE.equals(editingCustomer))
		{
			logger.log(Level.INFO, () -> DASHES + this.customerNumber + ":"
					+ this.sortcode + DASHES);
			logger.log(Level.INFO, () -> "Sortcode - " + this.sortcode);
			logger.log(Level.INFO, () -> "Customer name - " + this.getName());
			logger.log(Level.INFO,
					() -> "Customer address - " + this.getAddress());
