A Java class library that is useful for day-2-day development

The RS Library project was established to support my daily Java development. It is a collection of interfaces, classes and static Utils that are part of each of my projects. That’s why I decided to publish them the same way so everyone can benefit of the work. And of course, it will be easier for myself to fulfill common development tasks.

RS Library is divided into four areas, each of them published as a Maven module to RS Library:

• Base Library – provides non-specific code such as Java language tasks, IO tasks, bean handling, Configuration helpers and many more.
• Templating – provides an easy Typo3-like way of processing text templates within Java.
• Jackson – provides Jackson-based serialization/deserialization with JSON and YAML
• TOTP – provides TOTP generation and verification library

Most of this code was created when I faced specific problems in my professional work. I usually work out solutions in private projects, test them there and then apply them to my professional work. That’s why few of my employers will find the same code in their products. However, the code was created outside of professional environments and therefore is my own intellectual property.

RS Library modules are maintained in the same Maven project and, hence, follow the same release cycle. That means that each modules will have the same version numbers and are published at the same time.

Latest version is 5.2.2. Please note that Java 21 is required since 5.1.0.

V5 is a major release that removes several deprecated date and calendar classes. This includes the RsDate class and its descendants as well as some bean helper classes. They can be easily replaced nowadays with other standard libraries such as the Java Time API or commons-beans or alike.

V4 is a major release that marks several classes as deprecated. This includes the RsDate class and its descendants as well as some bean helper classes. They can be easily replaced nowadays with other standard libraries such as the Java Time API or commons-beans or alike.

V3 is a major release that removes the Data APIs. They will not be maintained any longer - in favour of Spring Data Framework. Do not upgrade to this version when you need the Data API.

V2 which has some minor compatibility breaks that result from upgrading commons-configuration dependency:

• Replace references to org.apache.commons.configuration.Configuration by org.apache.commons.configuration2.Configuration
• SubnodeConfiguration was removed in favour of HierarchicalConfiguration
• New utility methods for the ease of creating configurations from properties and XML files were added in ConfigurationUtils:
  • getXmlConfiguration() - will create a XMLConfiguration object from a given file or URL
  • getPropertiesConfiguration() - will create a PropertiesConfiguration object from a given file or URL
