Master Java Web Services and REST API with Spring Boot- 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 from being sent to the end consumer. It demonstrates setting up a filtering controller and using JSON Ignore annotations to exclude fields from responses, both for individual beans and lists of beans. The tutorial also covers the use of JSON Ignore Properties for more dynamic field exclusion, comparing static and dynamic filtering methods.

What is the primary purpose of filtering in a REST API response?

• To increase the size of the response

• To exclude unnecessary or sensitive data from the response

• To add more fields to the response

• To change the data type of fields in the response

In the FilteringController setup, what is the purpose of creating a simple bean?

• To demonstrate filtering by creating a basic data structure

• To store user credentials

• To manage user sessions

• To handle database connections

Which annotation is used to exclude a field from being serialized in the JSON response?

• @JsonFormat

• @JsonInclude

• @JsonProperty

• @JsonIgnore

What happens when you apply the @JsonIgnore annotation to a field?

• The field is included twice in the response

• The field's data type is changed

• The field is excluded from the JSON response

• The field is renamed in the response

What is a limitation of static filtering in REST APIs?

• It increases the response size

• It allows dynamic changes to the fields

• It requires hardcoding fields to be ignored

• It automatically updates field names

How can you exclude multiple fields from a JSON response using annotations?

• By using @JsonFormat

• By using @JsonProperty

• By using @JsonIgnoreProperties

• By using @JsonInclude

Why might you prefer using @JsonIgnore over @JsonIgnoreProperties?

• It requires less code

• It allows for dynamic filtering

• It automatically includes all fields

• It is less prone to errors when renaming fields
