• Welcome to NEJUG

    The New England Java Users Group is open to everyone interested in Java and the JVM. Meetings are usually held on the second Thursday of each month. The meetings and membership are free. We do not hold meetings in July and December. The NEJUG was formed in November 1998. We currently have over 6000 members. Meeting space is limited and we must ask members to register in order to attend meetings. It is common for over 300 people to register for a single meeting! What better way to meet new people interested in Java, development, architecture, or just get your technical questions answered.

  • Want to help?

    NEJUG is a volunteer driven organization, we can always use help from our community members, we can use your help with organizing the monthly meetings, adding new features and maintaining the website etc.,

      • Put Your Best Boot (Spring) Forward: Spring Boot Best Practices

        Thursday July, 14, 2022 06:30 PM
        Zoom Meeting
        Anywhere - MA

      Click here for Zoom Meeting

      In this example-driven session, we'll review several tips and tricks to make the most out of your Spring development experience. You'll see how these tips fit into a real (albeit small) Spring application and be able to take them with you as you apply them to your project.

      Spring has been the de facto standard framework for Java development for nearly two decades. Over the years, Spring has continued to evolve and adapt to meet the ever-changing requirements of software development. And for nearly half that time, Spring Boot has carried Spring forward, capturing some of the best Spring patterns as auto-configuration.

      As with any framework or language that has this much history and power, there are just as many ways to get it right as there are to get it wrong. How do you know that you are applying Spring in the best way in your application?

      NOTE: Registration is ONLY via MeetUp:

      MeetUp Registration: Creating Resilient Micro-Services.

      The foundation of Application Resiliency is often found in the application code where Fault Tolerance is baked into the application at the time of designing and coding….

      This presentation starts with building resiliency ground-up by baking the basic crucial patterns into the application. Resiliency4j provides the out of the box integration with Spring Boot, a defacto standard micro-service framework.

      The patterns discussed include:

      • Rate Limiter
      • Retry
      • Bulkhead
      • Circuit Breaker
      • Timeouts
      • Distilling Java Containers

      Three evolutionary ecosystems work well together: Java, Containers, and Kubernetes. Past versions of Java were never designed to be "container aware." This has led some to stray from the JVM to consider other shiny languages for Containers.

      But wait, let’s discover what Java 9, 10, 11, 12, 13 (…) has done to get our applications into efficiently distilled containers that pack nicely into Kubernetes.
