- Understand the core principles of Spring, and of Dependency Injection (DI) / Inversion of Control
- Use the Spring Core module and DI to configure and wire application objects (beans) together
- Know the different types of metadata (XML, annotations/@Component, and Java Configuration/@Configuration), and how and when to use them
- Understand and use the complete capabilities of the Core module, such as lifecycle events, bean scopes, and the Spring API
- Use Spring Boot to simplify dependency management and configuration
- Understand and use Boot’s auto-configuration
- Customize Boot’s behavior with properties and in other ways
- Work with the ORM (Object-Relational Mapping) module to integrate Spring with technologies such as JPA
- Use Spring Data to automatically generate JPA-based repository classes
