1. Madhura Bhave @madhurabhave23 WHAT’S NEW IN SPRING BOOT 2.0
2. Agenda •What’s New • Infrastructure Upgrades • Spring Framework 5 • Micrometer Support •What’s Changed • Configuration Properties • Actuator Endpoints • Security
3. What’s New •Infrastructure upgrades •Spring Framework 5 •Micrometer Support
4. Infrastructure upgrades 8+ 8+ 5.2 3
5. What’s New •Infrastructure upgrades •Spring Framework 5 •Micrometer Support
6. Reactive Spring •Blocking • Large thread pool required • Each request gets its own thread •Non-Blocking • Small thread pool • Worker threads process events
7. Reactive Spring •Servlet Stack • Servlet Container • Servlet API • Spring MVC •Reactive Stack • Netty, Servlet 3.1 • Reactive HTTP layer • Spring WebFlux
8. DEMO
9. Reactive Spring •Non-blocking •Event loop at the center •More for scalability than speed •You can still use Spring MVC
10. What’s New •Infrastructure upgrades •Spring Framework 5 •Micrometer Support
11. MICROMETER SUPPORT •Auto-configuration for metrics instrumentation library - Micrometer •Hierarchical metrics replaced by dimensional metrics •Facade over multiple monitoring systems
12. DEMO
13. What’s changed •Configuration properties •Actuator Endpoints •Security
14. DEMO
15. Configuration Properties •Relaxed Binding rules stay the same •Uniform format for reading properties from the environment • Elements separated by dots • Must be alpha-numeric • Must be lowercase • Hyphen can be used to separate words my.foo.hello-world my.foo.helloWorld my.foo.hello_world my.foo.helloworld
16. Configuration Properties •Indices in environment variables • my_foo_1 my.foo[1] • my_foo_1_2 my.foo[1][2] •Consistent behavior for Collections •Better types, e.g. Duration “1s” “2m” “5d” •Origin support
17. Properties Migrator <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-properties-migrator</artifactId> <scope>runtime</scope> </dependency>
18. What’s changed •Configuration properties •Actuator Endpoints •Security
19. DEMO
20. Actuator Endpoints •Endpoint annotations • @Endpoint, @WebEndpoint, @JmxEndpoint •Tech independent operations • @ReadOperation, @WriteOperation, @DeleteOperation •Tech specific extensions • @EndpointWebExtension, @EndpointJmxExtension https://2018.springio.net/sessions/mastering-spring-boots-actuator
21. Actuator Endpoints •Works with: • Spring MVC • Spring WebFlux • Jersey •Reactive Health Indicators •Overhaul of the “/actuator/mappings” & “/actuator/trace” endpoints
22. What’s changed •Configuration properties •Actuator Endpoints •Security
23. Security •Simpler security auto-configuration •Auto-configuration backs-off easily •Adding custom security is easy •No ordering issues with `WebSecurityConfigurerAdapter` •RequestMatchers for static resources and actuators •Auto-configuration for reactive security
24. Security •OAuth 2.0 • Moving to Spring Security 5.0 • Support for multiple client registrations • Authorization Server/Resource Server support https://github.com/spring-projects/spring-security-oauth2-boot
