    PowerMock

    PowerMock

    Java framework that allows you to unit test code normally

    Writing unit tests can be hard and sometimes good design has to be sacrificed for the sole purpose of testability. Often testability corresponds to good design, but this is not always the case. For example final classes and methods cannot be used, private methods sometimes need to be protected or unnecessarily moved to a collaborator, static methods should be avoided completely and so on simply because of the limitations of existing frameworks. PowerMock is a framework that extends other mock libraries such as EasyMock with more powerful capabilities. PowerMock uses a custom classloader and bytecode manipulation to enable mocking of static methods, constructors, final classes and methods, private methods, removal of static initializers and more. By using a custom classloader no changes need to be done to the IDE or continuous integration servers which simplifies adoption. Developers familiar with the supported mock frameworks will find PowerMock easy to use.

    Sakura Boot

    Sakura Boot

    Framework on top of spring-boot that helps create back-ends

    This framework, built on top of Spring Boot, is designed to speed up the development of robust backends. It ensures adherence to best practices while allowing a high degree of customization. The framework is structured using a modular architecture, making it easy to add or remove features based on the project’s specific needs. While Spring Boot speeds up the development process, developers still require extensive knowledge, must ensure adherence to best practices, and often write repetitive code for each project. First, the name Sakura Boot is named to reflect its foundation on Spring Boot, while "Sakura" symbolizing the brief cherry blossoms season in Japan, this highlights the framework’s focus on rapid and efficient backend development.

    Spring Data JPA

    Spring Data JPA

    Simplifies the development of creating a JPA-based data access layer

    Spring Data JPA, part of the larger Spring Data family, makes it easy to easily implement JPA-based repositories. This module deals with enhanced support for JPA-based data access layers. It makes it easier to build Spring-powered applications that use data access technologies. Implementing a data access layer of an application has been cumbersome for quite a while. Too much boilerplate code has to be written to execute simple queries as well as perform pagination, and auditing. Spring Data JPA aims to significantly improve the implementation of data access layers by reducing the effort to the amount that’s actually needed. As a developer, you write your repository interfaces, including custom finder methods, and Spring will provide the implementation automatically. Pagination support, dynamic query execution, ability to integrate custom data access code.

    Spring Data R2DBC

    Provide support to increase developer productivity in Java

    Provide support to increase developer productivity in Java when using Reactive Relational Database Connectivity. Uses familiar Spring concepts such as a DatabaseClient 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. Spring Data JDBC, part of the larger Spring Data family, makes it easy to implement JDBC-based repositories. This module deals with enhanced support for JDBC-based data access layers. It makes it easier to build Spring-powered applications that use data access technologies.It aims at being conceptually easy. In order to achieve this it does NOT offer caching, lazy loading, write-behind or many other features of JPA. This makes Spring Data JDBC a simple, limited, opinionated ORM.

    Sureness

    Sureness

    A simple and efficient security framework

    Sureness allows you to security any server written with jvm modern frameworks such as Spring, Spring Boot, Spring WebFlux, Javalin, Quarkus, Micronaut, Solon, Jfinal or Ktor as well as frameworks for Kotlin. The essence of Sureness is to use an interceptor (like a servlet filter or Spring interceptor) to intercept all rest requests for authenticating and authorizing. So no matter any framework, as long as it has an interceptor, it can integrate with sureness. Sureness uses Exception Handling Process, checkIn() will return SubjectSum(user information) when auth success, or throw different types of auth exceptions when auth error. Sureness has a sensible default configuration, is easy to customize, and is not coupled to any one framework, which enables developers to quickly and safely protect their projects in multiple scenarios.

    A Gateway built on Spring Framework and Spring Boot

    Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems (e.g. configuration management, service discovery, circuit breakers, intelligent routing, micro-proxy, control bus, one-time tokens, global locks, leadership election, distributed sessions, cluster state). Coordination of distributed systems leads to boiler plate patterns, and using Spring Cloud developers can quickly stand up services and applications that implement those patterns. They will work well in any distributed environment, including the developer’s own laptop, bare metal data centres, and managed platforms such as Cloud Foundry. Spring Cloud focuses on providing good out of box experience for typical use cases and extensibility mechanism to cover others.
