Spring Boot - Custom Password Validator Using Passay Library

Many online web platforms require users to enter a strong password during registration. This strategy helps reduce the vulnerability of user data to any hacking.

In this article, we’ll create a simple form with a registration page. Before continuing with this tutorial, you should have a basic understanding of Java with the Spring framework.

What Is Passay ?

Passay is a Java-based password generation and validation library. It builds on the success of vt-password and provides a comprehensive and extensible feature set.

Technology Stack

  • Node.js.
  • Angular 9.
  • Spring Boot 2.
  • Maven 3.6.1.
  • JAVA 8.
  • Git.

Maven Dependency

Use Spring Initializr to generate the spring boot 2 project with the dependencies: web, lombok, spring-boot-starter-validation.

Then add the Passay dependency to manage validation policies.

XML

  <dependency>
      <groupId>org.passay</groupId>
      <artifactId>passay</artifactId>
      <version>1.6.0</version>
  </dependency>

You can find all versions here.

Use the UserData class containing the information to verify.

Java

@PasswordValueMatch.List({
        @PasswordValueMatch(
                field = "password",
                fieldMatch = "confirmPassword",
                message = "Passwords do not match!"
        )
})
@AllArgsConstructor
@NoArgsConstructor
@Getter
@Setter
@ToString
public class UserData {

    @NonNull
    @NotBlank(message = "username is mandatory")
    private String username;

    @NotNull
    @NotEmpty
    @Email
    private String email;

    @ValidPassword
    @NonNull
    @NotBlank(message = "New password is mandatory")
    private String password;

    @ValidPassword
    @NonNull
    @NotBlank(message = "Confirm Password is mandatory")
    private String confirmPassword;
}

Two important annotations:

  • @PasswordValueMatch: Check if the password and confirmation password match.
  • @ValidPassword: Contains the password validation policy.

Spring Custom Validations

While building applications and services it is very important that we maintain data integrity especially if they are data centric. It is crucial to have control over the data that the application interacts with to ensure it behaves as expected. This can be done using validations.

Many times the data received may get corrupted before reaching the application or the user may provide wrong inputs. This will not create a problem if validations are applied as the application can return invalid requests and may ask the user to provide correct fields, but in absence of validations it is surely to cause problems at some instance, as it may process incorrect data and disrupt the flow.

Spring makes our lives easier by providing us with some build-in validations like

  • @NotNull
  • @NotBlank
  • @Size
  • @Min

But sometimes these are not enough. For eg when we need to validate a field which should only expect a 10 digit phone number. In cases like these we need to build our own custom validations.

In this blog we will have a look at how we can add custom validations with the help of an example.
