    Project mention: How to Make Java MRZ Detector with Dynamsoft Label Recognizer for Windows and Linux | dev.to | 2022-12-15

    The loadModel() method is special. It needs to dynamically update the model path specified in the JSON-formatted template file according to the extraction path of the Jar package. Gson can be used to load and update the JSON object.

    Project mention: "Shaping JSON" in Jackson without creating an object | reddit.com/r/javahelp | 2023-01-15

    after reading https://github.com/FasterXML/jackson-databind/issues/2239 but setting JsonCreator and adding the JsonFormat didn't work.

  • Apache Log4j 2

    Apache Log4j 2 is an upgrade to Log4j that provides significant improvements over its predecessor, Log4j 1.x, and provides many of the improvements available in Logback while fixing some inherent problems in Logback's architecture.

    Project mention: Log4Shell Still Has Sting in the Tail | news.ycombinator.com | 2022-12-30

    > When it was first revealed in early December 2021, the Log4Shell bug was described as one of the most severe security vulnerabilities ever.

    > The Apache Software Foundation, which maintains the open-source tool, quickly released a patch...

    Apache horribly mismanaged this and did not release a patch until it was already widely known and being exploited in the wild. They also messed up and had to release several subsequent patches to actually fix the vulnerability.

    Remember: this vulnerability was disclosed to them in November.

    https://github.com/apache/logging-log4j2/pull/608#issuecomme...

  • logstash-logback-encoder

    Logback JSON encoder and appenders

    Project mention: How to do JSON logging in Scala? | reddit.com/r/scala | 2022-10-22

    We're using https://github.com/logfellow/logstash-logback-encoder with logback (on Play Framework, but should work fine on Lambda as well).

  • Jackson

    Core part of Jackson that defines Streaming API as well as basic shared abstractions

    Project mention: Streaming Large JSON Response in Spring. | dev.to | 2022-10-07

    To put things simply, this method findAllStreaming() takes an OutputStream to write the whole json response into. To write json into the stream chunk by chunk we are using JsonGenerator. JsonGenerator is provided by Jackson-Core. More detailed about how to write stream event is covered in this blog post by the author of the library.

  • protostuff

    Project mention: Favorite hidden gem library? | reddit.com/r/java | 2022-10-21

    Project mention: Spring Boot — Power of Value Objects | dev.to | 2022-12-04

    Unfortunately, you cannot smoothly wrap the sequence-based IDs with value objects. There are solutions, but they are rather cumbersome. I left the proposal to the Hibernate types project of adding support to this feature. You’ve already seen the benefits of user-defined types. So, you can rate up my issue to make it more popular.

  • manifold

    Project mention: Opened a ticket to jetbrains around tailwind support for JTE | reddit.com/r/java | 2023-01-25

    Project mention: JEP draft: 64 bit object headers | news.ycombinator.com | 2022-10-11
  • jsoniter

  • proteus

    Project mention: Jetpack Compost has always been the future of Android development. This is the daily 2 minute reminder that all crashes are caused by RecyclerView. Creating a performant list has always been difficult. Optimization is overengineering. Logging is debugging. Lag is performance. LazyColumn. LazyColumn. | reddit.com/r/mAndroidDev | 2022-11-04
  • typescript-generator

    Generates TypeScript from Java - JSON declarations, REST service client

    Project mention: Options for high level front-end frameworks for Java developers | reddit.com/r/java | 2022-03-15

    I played with the tutorials and my impression was positive for both Flow and Hilla. The Vaadin Web Components have a high quality API, in particular the Grid is probably the best web component for data tables I have seen. The auto generation of the typescript objects in Hilla is very useful, not sure if there is anything equivalent (maybe this).

  • problem-spring-web

    A library for handling Problems in Spring Web MVC

    Project mention: Interview Question: What are your favorite Spring Boot libraries? | reddit.com/r/java | 2022-09-11

    That's a silly question. Yet, I'd probably answear https://github.com/zalando/problem-spring-web (which is a Spring extension for https://github.com/zalando/problem).

  • DSL-JSON

    High performance JVM JSON library

    Project mention: I benchmarked kotlin rust and go. The results will shock you , or not. | reddit.com/r/Kotlin | 2023-01-15

    Have you tried dsl-json instead of jsoniter? Should be faster.
