Udemy – The No Nonsense Guide to Java Spring Boot 2024-9

What you will learn

• Controller, Service, Repository layers: Understanding the basic building blocks of Spring Boot applications, including how to set up RESTful APIs, business logic layers, and data access layers.
• Exception Handling & Reponses: Master error handling best practices, define custom error responses, and return meaningful error messages in production.
• Validation: Implement input validation to ensure data integrity and protect against invalid requests.
• Query String Parameters, @Query, Search: Explore query string parameters, custom query methods with @Query, and interacting with databases using Spring Data JPA.
• JDBC, JPA, Hibernate, Spring Data, ORMs: Learn the differences between JDBC and JPA, understand ORM (Object Relational Mapping) with Hibernate, and when to use each in your applications.
• Unit Testing: Writing unit tests to ensure code is working correctly, covering both service and repository layers using tools like JUnit and Mockito.
• Headers: Learn how to work with request and response headers, implement custom headers, and effectively transfer data through API endpoints.
• Relational Mappings: Understanding how to model real-world relationships between entities in a relational database using JPA annotations.
• Logging: Implement effective logging strategies to track application behavior, debug problems, and monitor performance.
• Cache: Leverage cache strategies to improve application performance and scalability, including setting default cache and custom cache flush policies.
• External API Integration: Learn how to consume external APIs, manage authentication, and integrate third-party services into your Spring Boot application.
• Spring Security (Basic Auth): Explore built-in security mechanisms, set up basic authentication, and secure your applications with JWT (JSON Web Token) for token-based authentication.
• Spring Security (JWTs – JSON Web Tokens): Explore built-in security mechanisms, set up basic authentication, and secure your applications with JWT (JSON Web Tokens) for token-based authentication.
• Dependency Injection: A comprehensive understanding of how Spring Boot manages dependencies and objects, ensuring modular and maintainable code.
• Spring Boot Actuator: Enable real-time monitoring of your application, track performance metrics, and display health and status endpoints using Spring Boot Actuator.
• Transactions & @Transactional: Manage database transactions, understand transaction boundaries, and ensure data integrity using Spring’s @Transactional annotation.
• Dependency Injection, Inversion of Control, Spring Container: Understanding advanced Java concepts often used in Spring Boot applications, such as UUIDs for unique identifiers, event-driven programming, handling different return types, handling JSON data in MySQL, and implementing versioning for APIs you
