Master Microservices with Spring Boot and Spring Cloud - Step 25 – Implementing spring Cloud Gateway Logging Filter

The video tutorial explains how to add custom and global filters in API Gateway, focusing on creating a logging filter using Java and Spring Framework. It covers implementing the filter method, logging request paths, and activating the component. The tutorial also provides an overview of Spring Cloud Gateway, highlighting its features like request matching, load balancing, and path rewriting. The architecture involves handler mapping and executing filters before sending requests to services. The video emphasizes the importance of Spring Cloud Gateway in managing cross-cutting concerns such as security and monitoring.

What is the purpose of creating a logging filter in API Gateway?

• To encrypt request data

• To block unauthorized requests

• To enhance the speed of request processing

• To log every request passing through the gateway

Which interface must be implemented to create a global filter in API Gateway?

• ChainFilter

• ResponseFilter

• GlobalFilter

• RequestFilter

What is the role of SLF4J in the logging implementation?

• To handle user authentication

• To provide a logging framework

• To optimize network traffic

• To manage database connections

What must be added to activate the logging component in the API Gateway?

• A stereotype component

• A security certificate

• A new database connection

• A network firewall rule

Which of the following is NOT a feature of Spring Cloud Gateway?

• Load balancing

• Request matching based on attributes

• Integration with Spring Cloud Discovery

• Automatic code generation

What is the purpose of defining predicates in Spring Cloud Gateway?

• To optimize server performance

• To encrypt data

• To specify how requests should be matched

• To manage user sessions

How does Spring Cloud Gateway handle requests after they are matched?

• It encrypts them

• It applies defined filters

• It sends them to a random service

• It discards them
