    Sakura Boot

    Sakura Boot

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

    ...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-security-jwt-guide

    spring-security-jwt-guide

    Spring Security With JWT

    ...The goal is to show how to migrate from stateful, session-based auth toward stateless, modern REST API authentication using JWTs, roles, and permission checks. The code covers typical flows like user registration, login, logout, refreshing or invalidating tokens, and endpoint authorization with annotations like @PreAuthorize. It’s cleaner and more up-to-date than many older tutorials, reflecting current Spring and Java versions and allowing direct experimentation by developers.

    Framework for application developers to use state machine concepts

    ...It is advised to check the actual state of this project by referring to the latest releases found on the Spring Statemachine Project Page. The git repo default branch may be relatively unstable when new features are added to the source code. Spring Statemachine uses a Gradle-based build system. In the instructions below, ./gradlew is invoked from the root of the source tree and serves as a cross-platform, self-contained bootstrap mechanism for the build.

    Caffeine

    Caffeine

    A high performance caching library for Java

    ...In some cases a LoadingCache or AsyncLoadingCache can be useful even if it doesn't evict entries, due to its automatic cache loading. To improve integration, JSR-107 JCache and Guava adapters are provided in extension modules. JSR-107 standardizes a Java 6 based API to minimize vendor specific code at the cost of features and performance. Guava's Cache is the predecessor library and the adapters provide a simple migration strategy. Automatic loading of entries into the cache, optionally asynchronously and size-based eviction when a maximum is exceeded based on frequency and recency.

    Colorful

    Colorful

    Android dynamic skin resurfacing library

    ...It abstracts away the complexity of Android’s standard theming system and gives developers a higher-level API for tasks such as tinting UI components, generating complementary color palettes, and producing visually consistent themes based on a primary color. With Colorful, you can create adaptable interfaces that respond to user preferences, branding requirements, or content-specific hues without boilerplate code spread throughout your UI layer. The library also includes support for contrast adjustments and accessibility concerns, ensuring generated palettes remain legible and compliant with usability guidelines. Because color theming is central to modern app design, Colorful helps teams implement sophisticated, dynamic visual systems while preserving maintainability.

    Conscrypt

    Conscrypt

    Conscrypt is a Java Security Provider

    Conscrypt is a modern TLS/SSL provider for Java that replaces the default JCE/JCA crypto stack with one backed by BoringSSL for better performance and security posture. It is implemented as a drop-in SecurityProvider, so applications and frameworks can opt in without changing high-level HTTPS or socket code. The provider focuses on contemporary protocol hygiene—up-to-date cipher suite selection, ALPN, session resumption, and hardened defaults—so Java servers and clients negotiate secure connections by construction. Because it builds on BoringSSL’s audited primitives and constant-time implementations, it reduces the risk of subtle side-channel issues while improving handshake and bulk crypto throughput. ...

    Flogger

    Flogger

    A Fluent Logging API for Java

    Flogger is a structured logging API for Java that decouples how you log from where logs ultimately go, making it easy to change backends without rewriting application code. Instead of building messages eagerly, it uses lazy parameter evaluation so expensive string building only happens when a log statement is actually emitted. The API encourages structured key–value context and fine-grained rate limiting, which helps keep logs informative without flooding systems during high-traffic or error storms. ...
