Spring Session MongoDB 2.0.0.M1 released

Dear Spring Community,

Last month, Spring Session lead Rob Winch announced the release of Spring Session 2.0.0.M1 (notice the lack of MongoDB there?) In that post, he pared back Spring Session to officially supporting Redis, JDBC, and Hazelcast. No more MongoDB.

I’m here to announce that I’ve pick up the torch for Spring Session MongoDB. Managing both Spring Session and Spring Security (among other responsibilities), Rob couldn’t maintain high caliber support with too many data stores. Being a member of the Spring Data team, I felt better suited toward providing MongoDB support of Spring Session, so I reinstated it as a separate project.

Spring Cloud Spinnaker 1.0.0.M3

Greetings Spring community,

I am happy to release the second milestone for Spring Cloud Spinnaker. Spring Cloud Spinnaker bundles up the continuous delivery Spinnaker platform, and provides a 1-click installer to let you install it to any certified Cloud Foundry provider.

UPDATE: This blog post originally cited M2, however one of our early adopters spotted a critical bug, so M3 has been built and released with the fix in hand.

Key features included in this release:

  • Much more simplified way to login, select your org and space from dropdowns, etc., shooting for as simple an experience as possible.

  • Ability to manage two CF spaces

  • Support for Jenkins and Travis CI monitoring.

  • Configure email and slack notifications

  • Move to hosted uber JARs, meaning installing the installer is no longer a bugbear

  • Other enhancements regarding to Spinnaker itself include ability to clone server groups, an upgrade to our Reactor-based cf-java-client 2 library, and also enhance UX showing more CF information than ever.

Spring Cloud Spinnaker 1.0.0.M1

Greetings Spring community,

I am happy to release the first milestone for Spring Cloud Spinnaker. Spring Cloud Spinnaker bundles up the continuous delivery Spinnaker platform, and provides a 1-click installer to let you install it to any certified Cloud Foundry provider.

At this year’s SpringOne Platform 2016 conference, there were two talks about Spinnaker. If you have early release access and missed them, you can watch right now. Otherwise you can catch them on the SpringDeveloper YouTube Channel once they are published.

Reactor guides deprecated

Greetings Spring community,

There has been a lot of buzz in the past six months over Spring 5 and Reactive Streams support. I personally witnessed the number of questions Rossen received during his Reactive Spring MVC talk at DevNexus back in March. And his reactive talk at Spring I/O conference more recently was VERY popular to attenders.

Based on the huge leaps and bounds Project Reactor has made in the past two years, we are taking two of our guides down:

  • Creating an Asynchronous, Event-Driven Application with Reactor

  • Uploading pictures with Reactor

Check out our new tutorial -> React.js and Spring Data REST

Greetings Spring Community,

I hope you enjoyed my blog series on React.js + Spring Data REST. In that series, you got to build up a rich web app with hypermedia controls, conditional operations, messaging, and security.

To make things even better, that series has been bundled up and converted into a tutorial: https://spring.io/guides/tutorials/react-and-spring-data-rest/

Some key updates made along the way:

  • require.js has been replaced with webpack as the JavaScript module builder/loader of choice
  • The code is upgraded to ES6. This means that some of JavaScript’s newest features like classes, arrow functions, and more are being used.
  • bower has been replaced by npm as the package manager of choice

React.js and Spring Data REST: Part 5 - Security

To see updates to this code, visit our React.js and Spring Data REST tutorial.

In the previous session, you made the app dynamically response to updates from other users via Spring Data REST’s built in event handlers and the Spring Framework’s WebSocket support. But no application is complete without securing the whole thing so that only proper users have access to the UI and the resources behind it.

Feel free to grab the code from this repository and follow along. This session is based on the previous session’s app with extra things added.

React.js and Spring Data REST: Part 4 - Events

To see updates to this code, visit our React.js and Spring Data REST tutorial.

In the previous session, you introduced conditional updates to avoid collisions with other users when editing the same data. You also learned how to version data on the backend with optimistic locking. You got a tip off if someone edited the same record so you could refresh the page and get the update.

That’s good. But do you know what’s even better? Having the UI dynamically respond when other people update the resources.

In this session you’ll learn how to use Spring Data REST’s built in event system to detect changes in the backend and publish updates to ALL users through Spring’s WebSocket support. Then you’ll be able to dynamically adjust clients as the data updates.

Feel free to grab the code from this repository and follow along. This session is based on the previous session’s app with extra things added.

React.js and Spring Data REST: Part 3 - Conditional Operations

To see updates to this code, visit our React.js and Spring Data REST tutorial.

In the previous session, you found out how to turn on Spring Data REST’s hypermedia controls, have the UI navigate by paging, and dynamically resize based on changing the page size. You added the ability to create and delete employees and have the pages adjust. But no solution is complete with taking into consideration updates made by other users on the same bit of data you are currently editing.

Feel free to grab the code from this repository and follow along. This session is based on the previous session’s app with extra things added.
