Let’s digging to code

• Building cloud native Java application – Use Spring boot cloud components Set up->start.spring.io What you need →Java 8, maven 3.1 or above IDE,might need Spring boot CLI, might need Spring Cloud CLI

Why?

• Why Spring• Why Jar, not war• Why by-name links for searching services

–

Demo

• The Config Server• Service Registration and Discovery• Edge Services: API gateways (circuit

breakers, client-side load balancing)• To the Cloud!• Security• Consumer Driven Contract Testing and

more!
