Focus Areas

• Building RESTful APIs with Spring MVC
• Dependency injection and inversion of control
• Spring Boot configuration and properties management
• Secure application development with Spring Security
• Data access with Spring Data JPA and JDBC
• Creating microservices with Spring Cloud
• Using Spring Boot Actuator for monitoring and management
• Utilization of Spring Boot starters for rapid application development
• Exception handling with Spring Boot
• Implementing caching mechanisms with Spring Cache

Approach

• Use opinionated defaults provided by Spring Boot to speed development
• Prefer constructor injection for mandatory dependencies
• Use @ConfigurationProperties for type-safe configuration
• Build secure applications by default by leveraging Spring Security
• Simplify data access by using Spring Data JPA and repositories
