Spring Boot 1.5 Highlights

New in Spring Boot 1.5: Spring for Apache Kafka support

Autoconfiguration

• Add maven dependency

• Configure properties• Done!

Spring for Apache Kafka

Actuators in Spring Boot

About Actuators/health/info/env /metrics /shutdown

Example endpoints

/health/info/env /metrics /trace/auditevents/autoconfig/shutdown…

Built in JMX / HTTP endpoints to help you monitor and manage your application

Potentially sensitive information available

Actuator Security before Spring Boot 1.5 No Spring Security – everything exposed! With Spring Security – login with default user

Actuator Security in Spring Boot 1.5

Boot 1.5 Security

New Actuator: Loggers Get all loggers Get individual logger Change configuration for specific logger

Logging Configuration

Spring Boot <3 Pivotal Cloud Foundry

Spring Boot <3 Pivotal Cloud Foundry?

Actuator integration into Apps Manager• Eye-catcher to indicate it’s a boot

application

• Augmented health information

• Git information

• Runtime configuration of loggers

• Transparent security integration with Pivotal Cloud Foundry UAA

Pivotal Cloud Foundry

Apps Manager

How does it work?

Expose

• Expose via/cloudfoundryapplication

Protect

• UAA Tokens• Cloud Controller roles

Other 1.5 Highlights

Audit events endpoint

• Authentication and Authorization audited by default

• Extensible for your audit events

LDAP Support

• Autoconfiguration for any LDAP-compliant server

• In-memory LDAP from UnboundID for easier testing

Looking ahead

What’s ahead for Spring Boot 2.0? Spring Boot 2.0 will support Spring WebFlux and Spring Framework 5.0 Autoconfiguration for full-stack reactive applications Support for Java 9 Support for Java EE 8 (e.g. Servlet 4 and Bean Validation) Support major generation updates of Spring projects• e.g. Spring Integration 5.0, Spring Session 2.0, etc

Pluggable reactive runtimes - Apache Tomcat, Reactor Netty, Jetty, Undertow*

What’s ahead for Spring Boot & Pivotal Cloud Foundry

Working on the next set of Spring Boot Actuators!

/heapdump/dump/trace

What’s ahead for Spring Boot & Pivotal Cloud Foundry? MOAR Actuators! Like, all of them except /shutdown and /logfile Piping Spring Boot Actuator custom /metrics into PCF Metrics UX Considering reactive Actuator endpoints Considering Microservices Dashboard

What else? If you use Boot & Pivotal Cloud Foundry, we’d like to hear from you!

Spring and Pivotal Cloud Foundry: Spring Cloud Services

What is Spring Cloud Services (SCS)?• 100% PCF managed NetflixOSS Eureka, Hystrix and Pivotal Config server

• Now in public beta on Pivotal Web Services (PWS)

Things we’re considering for SCS 1.3 + • Config Server composite backends (Vault & Git)

• Spring Cloud Data Flow support

• Support PCF surgical routing, C2C networking in SCS Connector client

• Service Registry sharing across more than CF Orgs/Spaces, arbitrary linking

• Evolve config server into a more self-contained config management product

• Service registry dynamic routing (pair Eureka instances with Zuul instances)

PCF Metrics and Spring Cloud Sleuth: Trace Explorer

Detect in logs that Zipkin trace output is present

Examine in PCF Metrics time series user interface• Will find all logs with that trace ID

• Which services did it touch

• Will give span (timing)

• Call hierarchy

Learn More. Stay Connected.
