Master Microservices with Spring Boot and Spring Cloud - Step 15 – Implementing Validations for RESTful Services

The video tutorial covers the implementation of validation in user services using the Java Validation API within a Spring Boot application. It begins with an introduction to user services and the need for validation. The tutorial then demonstrates how to add validation annotations to user data, handle validation errors, and customize error messages. It also explores various validation constraints available in the Java Validation API and highlights the ease of integrating these features using Spring Boot.

What is one of the key requirements when dealing with user services?

• Database optimization

• User validation

• User interface design

• Data encryption

Which annotation is used to enable validation on a user in Java?

• @Verify

• @Valid

• @Check

• @Validate

What is the purpose of the @Size annotation in Java Validation API?

• To restrict the size of a string

• To validate a date is in the past

• To ensure a string matches a pattern

• To check if a number is within a range

What HTTP status code is returned when a validation error occurs?

• 200 OK

• 404 Not Found

• 500 Internal Server Error

• 400 Bad Request

Which method is overridden to handle validation errors in a customized response handler?

• handleResponseException

• handleRequestError

• handleMethodArgumentNotValid

• handleValidationError

What does the @Past annotation ensure about a date?

• It is today's date

• It is in the future

• It is a weekend

• It is in the past

Which package contains various constraints for validation in Java?

• com.validation.constraints

• org.hibernate.constraints

• java.util.constraints

• javax.validation.constraints

What is the most popular implementation of the Java Validation API?

• Hibernate Validator

• Spring Validator

• Apache Validator

How does Spring Boot simplify the use of the Java Validation API?

• By offering a command-line tool

• By automatically configuring dependencies

• By integrating with cloud services

• By providing a graphical interface

What is the benefit of using Spring Boot starter web in validation?

• It enhances security features

• It includes necessary validation dependencies

• It simplifies database connections

• It provides a user interface
