. Hutool is a "Swiss Army knife" for Java developers, providing a comprehensive set of static methods to simplify common tasks like date manipulation, HTTP requests, and encryption. Key Updates in Version 5.8.26
| Module | Description | | :--- | :--- | | | The heart of Hutool. Includes all essential utilities for Beans, dates, strings, numbers, and collections. This is the minimum required module for most projects. | | hutool-http | The re-engineered HTTP client, supporting a facade pattern for multiple underlying implementations. | | hutool-json | Provides robust JSON parsing and serialization, including JSONObject , JSONArray , and JSONUtil for conversion between beans and JSON. | | hutool-ai | The milestone module for integrating with AI LLMs like OpenAI and DeepSeek. | | hutool-cache | Offers simple caching implementations. | | hutool-crypto | Encapsulates symmetric, asymmetric, and digest encryption algorithms. | | hutool-db | Provides JDBC encapsulation, enabling ActiveRecord-style database operations. | | hutool-cron | A task scheduling module using Cron expressions. |
Hutool is designed to reduce the cost of learning complex Java APIs and to make the code more readable—or "sweet," as the maintainers put it. Low Overhead
Released in early 2024, focused heavily on stability, bug fixes, and refining existing utility modules to meet modern development standards. Key Updates and Fixes: hutool 26
Type conversion in Java usually requires manual casting or parsing classes like Integer.parseInt() . Hutool’s Convert class acts as a universal translator.
One of the biggest headaches for enterprise developers migrating to Spring Boot 3 is the namespace change from javax.servlet to jakarta.servlet . Hutool 26 completely refactors its web utilities ( ServletUtil , HttpUtil ) to support .
Hutool is modular, meaning you can import only what you need: Includes all essential utilities for Beans, dates, strings,
Hutool is a "sweet" Java utility library that encapsulates common boilerplate code into static methods. The was a stable maintenance update within the 5.8.x branch. Key Features and Modular Design
Hutool 2.6 is versatile and can be applied to various development scenarios, including:
File I/O in vanilla Java is notoriously verbose. Hutool 2.6 made it a joy. | | hutool-json | Provides robust JSON parsing
: IdUtil.randomUUID() and performance-optimized IdUtil.fastSimpleUUID() build rapid tracking strings.
Managing key-value pairs often requires boilerplate code to handle missing keys or complex structural mapping.
: Creating codes to activate navigation, maps, or Apple CarPlay.
The most visible change is the . The familiar cn.hutool root was replaced with org.dromara.hutool . This change was made to officially align Hutool under the Dromara open-source community, analogous to how an Apache project would use an org.apache namespace. Additionally, many core utility classes were moved to more specific sub-packages. For example, string utilities moved to org.dromara.hutool.core.text and collection utilities to org.dromara.hutool.core.collection . This makes the code more organized but means a simple version bump will not work; almost every import statement in a codebase would need updating.
