    EnvFile

    EnvFile

    EnvFile 3.x is a plugin for JetBrains IDEs

    Env File is a plugin for JetBrains IDEs that allows you to set environment variables for your run configurations from one or multiple files. Not all run configurations available in IDEA-based IDEs are implemented similarly. Some of them differ significantly. In certain cases (so far, only Gradle has been confirmed) the implementation exposes interfaces to integrate the EnvFile UI but doesn't provide interfaces for it to actually make its work. Luckily, it was possible to make few assumptions about IDEA's internal implementation and make it work. Such integration is very fragile and it's not immediately clear if it will affect any existing integrations and when it will break. For that reason there is a special option to Enable Experimental Integrations that can be enabled when desired and should prevent other integrations from breaking.

    Spring Data Redis

    Spring Data Redis

    Provides support to increase developer productivity in Java

    Provides support to increase developer productivity in Java when using Redis, a key-value store. Uses familiar Spring concepts such as a template class for core API usage and lightweight repository-style data access. The primary goal of the Spring Data project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud-based data services. Connection package as low-level abstraction across multiple Redis drivers (Lettuce and Jedis). Exception translation to Spring’s portable Data Access exception hierarchy for Redis driver exceptions. RedisTemplate that provides a high level abstraction for performing various Redis operations, exception translation and serialization support. Pubsub support (such as a MessageListenerContainer for message-driven POJOs). Redis Sentinel and Redis Cluster support. Reactive API using the Lettuce driver. JDK, String, JSON and Spring Object/X.

    JSON Schema Validator

    JSON Schema Validator

    A fast Java JSON schema validator that supports draft V4, V6, V7, V201

    This is a Java implementation of the JSON Schema Core Draft v4, v6, v7, v2019-09 and v2020-12(partial) specification for JSON schema validation. In addition, it also works for OpenAPI 3.0 request/response validation with some configuration flags. For users who want to collect information from a JSON node based on the schema, the walkers can help. The default JSON parser is the Jackson which is the most popular one. As it is a key component in our light-4j microservices framework to validate request/response against OpenAPI specification for light-rest-4j and RPC schema for light-hybrid-4j at runtime, performance is the most important aspect in the design.

    Ason

    Ason

    This library intends to make JSON very easy to interact with in Java

    This library intends to make JSON very easy to interact with in Java; it also makes (de)serialization painless. It wraps around the well-known org.json classes (JSONObject, JSONArray, etc.) which also happen to be included in the Android SDK. As we all know, those stock classes tend to be a pain. They feel bulky, and make you try/catch way too many exceptions.

    keycloak-config-cli

    keycloak-config-cli

    Import YAML/JSON-formatted configuration files into Keycloak

    keycloak-config-cli is a Keycloak utility to ensure the desired configuration state for a realm based on a JSON/YAML file. The format of the JSON/YAML file is based on the export realm format. Store and handle the configuration files inside git just like normal code. A Keycloak restart isn't required to apply the configuration. The config files are based on the keycloak export files. You can use them to re-import your settings. But keep your files as small as possible. Remove all UUIDs and all stuff that is default set by keycloak.

    Problems for Spring MVC

    Problems for Spring MVC

    A library for handling Problems in Spring Web MVC

    Problem Spring Web is a set of libraries that makes it easy to produce application/problem+json responses from a Spring application. It fills a niche, in that it connects the Problem library and either Spring Web MVC's exception handling or Spring WebFlux's exception handling so that they work seamlessly together, while requiring minimal additional developer effort. In doing so, it aims to perform a small but repetitive task — once and for all.

    jsonschema2pojo

    jsonschema2pojo

    Generate Java types from JSON or JSON Schema for data-binding

    Generate plain old Java objects from JSON or JSON-Schema. For each property present in the 'properties' definition, we add a property to a given Java class according to the JavaBeans spec. A private field is added to the parent class, along with accompanying accessor methods (getter and setter). If additionalProperties is specified and set to the boolean value false, then the generated Java type does not support additional properties. If the additionalProperties node is undefined (not present), null or empty, then a new bean property named "additionalProperties", of type Map<String,Object> is added to the generated type (with appropriate accessors). The accessors are annotated to allow Jackson to marshal/unmarshal unrecognised (additional) properties found in JSON data from/to this map.

    xsd2pgschema

    Relational database replication tool based on XML Schema

    xsd2pgschema is a Java application suite, which converts XML Schema 1.1 (hierarchical data model) to PostgreSQL DDL (relational data model) and supports XML data migration into PostgreSQL based on the XML Schema without defects on information content. It also supports full-text indexing via either Apache Lucene or Sphinx Search utilizing the relational data model. File conversion from XML to CSV, TSV, or JSON is possible as well as mapping XML Schema to JSON Schema. Obtained PostgreSQL database can be optimized at user's discretion. Moreover, differential update, and XPath query evaluation over PostgreSQL are possible. PgSchema server, serialized relational data model server, can be used to speed up the analysis of complex XML Schema. Large XML file can be split through xmlsplitter, a flexible XML splitter based on XPath and StAX.

    Jigy Generator Windows

    Jigy Generator Windows

    The best way to generate a Spring Java Web Application. It just works!

    The Jigy Generator is the simplest way to build and code a Java web application with a Spring Framework by using a project creation wizard and now it's been made even simpler by downloading a very small HTML file (337 bytes) and filling out a few form fields and let it construct your project with ease! The resulting project will be a Java web application with a Spring Framework configured to run in Eclipse or Netbeans. The project is annotation-based and provides dependency injection of project resources and simple annotation-based transaction management. Your created project will be already configured to connect to your project's database and to return JSON responses when required. Also the login and file upload modules will be fully functional immediately upon project creation. We promise once you've Jigy Generated a project, you will never want to start from scratch again! http://getjigy.com

    Artemis

    Cassandra "ORM" with hooks for Jersey integration if desired

    Using the new CQL3 driver by Datastax Artemis provides extremely easy to use "ORM" like functionality for Cassandra. It also contains hooks for integration into Jersey2 to enable rapid development of RESTful services, or even websites, if you enable JSP functionality for Jersey. If there is a demand, I could add a plugin to render views using things like Velocity, etc. See https://sourceforge.net/p/wicca/wiki/Home/ for more documentation
