Master Microservices with Spring Boot and Spring Cloud - Step 24 – Implementing Static Filtering for RESTful Service

The video tutorial explains the concept of filtering in data responses, focusing on how to exclude certain fields, such as sensitive information, using JSON Ignore annotations. It covers setting up a filtering controller, creating beans, and applying JSON Ignore to both single and list responses. The tutorial concludes with a discussion on static versus dynamic filtering methods.

What is the main purpose of filtering in a REST API?

• To increase the size of the response

• To change the data type of fields

• To exclude certain fields from the response

• To enhance the speed of the API

In the filtering example, what is the first step in setting up the FilteringController?

• Creating a new database

• Defining a REST controller

• Setting up a user interface

• Writing a complex algorithm

What does the JSON Ignore annotation do?

• Changes the data type of a field

• Excludes a specific field from the response

• Includes all fields in the response

• Adds additional fields to the response

How does the JSON Ignore annotation affect a list of beans?

• It excludes the specified field from all beans in the list

• It only affects the first bean in the list

• It duplicates the specified field in all beans

• It changes the order of fields in the list

What is a limitation of using static filtering with JSON Ignore?

• It cannot handle different scenarios for different fields

• It requires dynamic configuration

• It cannot exclude any fields

• It automatically includes all fields

What is the advantage of using JSON Ignore Properties over JSON Ignore?

• It includes all fields by default

• It changes the data type of fields

• It requires less code

• It allows excluding multiple fields at once

Why might one prefer using JSON Ignore over JSON Ignore Properties?

• It is faster to implement

• It is easier to maintain when renaming fields

• It is more dynamic

• It allows for more fields to be included
