The document discusses microservices, Spring Boot, UI5, and OData. It describes how microservices are stateless, service-oriented, and loosely coupled. It explains that Spring Boot allows for quick development while including features like metrics and pluggable capabilities. It then discusses how UI5 tiles can each have their own backend microservice with isolated databases and communication through APIs. The document promotes using OData with UI5 for entity definition and CRUD operations and using Spring Boot for entity definition and repository logic without additional code. It introduces an OData/UI5 boilerplate project that applies the microservices pattern and includes plumbing for UI5, OData, and linking to JPA entities to rapidly build prototypes.

1. Jan Penninkhof – PhoQus B.V.
Next-Gen OData/UI5 Microservices with
Spring Boot

2. Hello!

3. What is a
micro-service?
• Stateless
• Service oriented
• Autonomously running
• Continuous Integration
• Loosely coupled
• High level of resilience

4. Spring Boot
Get’s your started really quickly, but still includes features such as:
 Metrics
 Pluggable (Social, twitter, persistency, hystrix etc)
 Run as War in Tomcat or HCP, Runs as Jar on Docker, VM, Azure
 Easy to transport, easy to scale

5. Fiori and Micro-services
 Every tile has it’s own UI5 app and it’s own back-end application
 Runs as isolated micro-services
 Communication with other components through APIs
 Isolated database persistency
What do you think of something like this?

6. UI5 works best on OData
 OLingo is awesome
 Just define your entities and you’re done!
 Customizable: include transient/calculated attributes, adapt metadata based on context, add
custom/smart annotations
 Spring Boot is awesome
 Just define your entities and you’re done!
 Codeless repository logic for CRUD + filter-logic
 Uses Liquibase to take care of schema changes and hibernate to connect to your data
source. Unobtrusively, no code required!

7. OData/UI5 boilerplate
 Applying micro-services pattern
 Deploys on various platforms, including HCP, HANA
 Includes plumping to include UI5 app
 Includes plumbing to provide OData service based on Olingo
 Includes plumbing to link Olingo to JPA data entities
 Includes boilerplate code for custom/smart annotations
 Automatically creates and updates database-schema based on application entities
 Includes simple UI5 app to showcase some of the features

8. What can it be used for
 Rapidly build your own microservice without having to do the basic plumbing
 Quickly setup a prototype application that includes a back-end
 Win an Innojam/Hackathon!
