Build production-ready, standalone Spring Boot microservices with embedded Tomcat, Spring MVC RESTful controllers, Spring Data JPA / Hibernate persistence, JWT Spring Security authentication, and Actuator metrics.
Spring Boot simplifies Spring application development by providing opinionated auto-configuration, embedded web servers, and executable JAR packaging. It is the dominant choice for modern cloud-native microservices.
In this flagship program, you will design RESTful APIs adhering to HTTP standards, map relational database entities with Hibernate/Spring Data JPA, implement stateless JWT authentication with Spring Security, handle global exceptions with @ControllerAdvice, and manage production Actuator endpoints.
Spring Boot Initializer, Starter Dependencies, @SpringBootApplication internals, Auto-configuration mechanism (@EnableAutoConfiguration), application.properties/yml profiles.
@RestController, @GetMapping, @PostMapping, @PutMapping, @DeleteMapping. Request payload validation (@Valid), DTO pattern mapping, Custom Response Entities, and @ControllerAdvice exception handling.
JPA Entity mapping (@Entity, @Table, @Id, @GeneratedValue). Entity Relationships (@OneToMany, @ManyToOne, @ManyToMany). JpaRepository interfaces, Derived Query methods, and JPQL queries.
Spring Security Filter Chain, UserDetailsService, Password Encoding (BCrypt), JWT token authentication, RestTemplate / WebClient inter-service communication, and Actuator metrics.
