Java Development

RESTful API with SPRING BOOT

01 Spring Boot

Goals

Fast quick start experience

• Provide a radically faster and widely accessible getting started experience for all Spring development.

Reference: [1] http://docs.spring.io/spring-boot/docs/1.2.2.BUILD-SNAPSHOT/reference/htmlsingle/#boot-documentation

01

Convention Over Configuration

• Be opinionated out of the box, but get out of the way quickly as requirements start to diverge from the defaults.

Reference: [1] http://docs.spring.io/spring-boot/docs/1.2.2.BUILD-SNAPSHOT/reference/htmlsingle/#boot-documentation

01

Non-functional features

• Provide a range of non-functional features that are common to large classes of projects (e.g. embedded servers, security, metrics, health checks, externalized configuration).

Reference: [1] http://docs.spring.io/spring-boot/docs/1.2.2.BUILD-SNAPSHOT/reference/htmlsingle/#boot-documentation

01

No required XML configuration

• Absolutely no code generation and no requirement for XML configuration.
