Course Notes

Spring Web Servers

There are 2 servers:

1. Tomcat (default)
2. Jetty (change pom.xml)

N Tier Architecture

This architecture is structure in layers as follows:

1. Client
2. REST Layer (POST, GET, PUT, DELETE) (Controllers)
3. Service Layer (business logic)
4. DAO (Data Abstracion Object) Layer

Annotations

@Component - Is a singleton (one instance instead of creating multiple instances). Creates one instance that we can then inject @RestController - Is like @Component, but more specific annotation @Service - Is like @Component, but more specific annotation @Repository - Is like @Component, but more specific annotation @GetMapping @PutMapping @PostMapping @Primary @Autowired @Qualifier @Bean - Add configuration steps before a class is initialized @Configuration
