Hi Spring fans! Welcome to another installment of This Week in Spring! This week I was in Beijing, China for the fabulous Spring Summit event which saw technologists from all around China descend on the capitol for a discussion of all things cloud native and Spring. Then I'm off to Shenzhen, China and Hong Kong for customer visits and the epic YOW! Hong Kong show!

• Pivotal have released a commercial version of the Concourse CI pipeline tool for Cloud Foundry. Check it, and Spring Cloud Pipelines, out!
• I liked Bruno Leite's post on error handling in a Spring Boot-based REST API.
• You might like Baeldung's post on using GraphQL with Spring Boot
• This project seems interesting, though I haven't used it yet. It lets you use ModelMapper with Spring Boot applications.
• This is a great find by community legend Tommy Ludwig who noticed that Bitbucket is now running on Spring Boot!
• This post is an oldie but a goodie since my JavaScript-fu is not the strongest. It looks at how to use Angular (2 or better) with websockets powered by a Spring Boot application.
• IntelliJ advocate and superstar Trisha Gee looks at the new features in IntelliJ IDEA 2017.2 designed to support Spring Boot applications.
• Distributed tracing guru Adrian Cole looks at how to properly blame things for latency in this epic microXchg talk.
• This article is a recap of a talk by David Dawson. It has little to do with Spring itself, directly, and everything to do with event-driven architectures. It's a nice discussion and you'll find supporting tools in technologies like Spring Cloud Stream, Spring Cloud Data Flow and the Axon framework.
• I liked this look at the new support for regular expressions in Java 9.
• The branch of the US gov't charged with digital transformation - started many years ago - is looking for some cloud natives familiar with Cloud Foundry to help them.
