Added built-in text-to-image (文生图) endpoint wrappers for ByteDance’s Doubao (豆包) and xAI’s Grok .

While Hutool is powerful, here are a few tips to use it effectively:

| Problem | Without Hutool | With Hutool (Method #) | |---------|----------------|------------------------| | Null-safe string conversion | 3 lines + ternary | 1 line (#1) | | Read file to string | 10 lines (try-with-resources) | 1 line (#11) | | POST JSON to API | 30 lines (HttpURLConnection) | 2 lines (#15, #16) | | Deep copy a bean | manual get/set every field | 1 line (#30) |

This release expanded Hutool's reach into generative AI while continuing to refine its massive collection of "util" packages. Expanded AI Capabilities New HutoolAI Platform

Leveraging the new functional extensions in hutool-ai , developers can stream prompt token emissions directly to consumers:

The 5.8.39 update introduces several modern features and performance optimizations designed to keep pace with evolving developer needs. 1. Enhanced AI Integration

As of its recent stable release, (released June 2025) continues to serve as a comprehensive "Swiss Army Knife" for Java development. By encapsulating complex logic into simple static methods, it reduces the cost of learning APIs and makes Java feel as elegant as a functional language. What’s New in Hutool 5.8.39? Leveraging the new functional extensions in hutool-ai ,

Simplifies encryption and decryption, including AES, DES, RSA, and Digest algorithms [4].

boolean isEmpty = StrUtil.isBlank(myStr); String subString = StrUtil.sub(myStr, 0, 5); Use code with caution. 3. File Operations

The next time you write a for loop to join strings, or a try-catch to parse a date, stop yourself. Ask: “Which of the 39 methods does this?”

boolean isEmpty = StrUtil.isEmpty(" "); // false boolean isBlank = StrUtil.isBlank(" "); // true Can’t copy the link right now

Java is strongly typed, but data comes from external sources (HTTP, files, databases) as strings or objects. Convert removes the try-catch hell of SimpleDateFormat or Integer.parseInt .

: Ensuring that third-party integrations (e.g., Jackson or Netty) are updated to avoid inherited security flaws. hutool-all » 5.8.39 - Maven Repository

Developers can now inject global and granular timeout limits on AI requests, mitigating hang-ups during peak API traffic.
