Hutool | 39 New [new]

New support for SSE (Server-Sent Events) with a custom callback parameter allows you to handle real-time streaming responses from LLMs. This is crucial for building chat interfaces that feel responsive.

. True to its mission, Hutool continues to reduce the cost of learning complex APIs and makes writing Java feel as elegant as a functional programming language.

// Before: manual checks for (String s : list) if (s.startsWith("H")) doSomething(s);

The DateUtil in this version was a favorite among users for its ability to parse almost any date string format automatically and perform complex date arithmetic (e.g., DateUtil.offsetMonth ) in a single line.

// Run every Monday at 9 AM with virtual thread executor CronUtil.schedule("0 0 9 ? * MON", "reportJob", () -> try (var exec = ThreadUtil.newVirtualExecutor()) exec.submit(() -> generateDailyReport()); hutool 39 new

Potential sections:

: Follows a strict "no-dependency" principle (except in the extra module), keeping projects lean.

Enter the newest major generation of the library: . Representing the fresh, redesigned future of the ecosystem, Hutool v6 delivers radical performance optimizations, a brand-new package architecture under the Dromara umbrella, and streamlined functional patterns.

began humming, scheduling background tasks with surgical precision that the old legacy code could never dream of. New support for SSE (Server-Sent Events) with a

If you are looking for specific module updates (e.g., hutool-core , hutool-crypto , or hutool-cache ), these are typically bundled in the hutool-all artifact. hutool/README-EN.md at v5-master - GitHub

The 5.8.39 version is not merely a bug-fix baseline; it introduces foundational features tailored for asynchronous batch performance and deep integration with emerging modern AI providers.

Handling Excel files and complex JSON payloads remains one of the most common tasks for enterprise developers. Hutool 39 brings massive performance lifts here:

// Read lines with filtering and encoding List<String> lines = FileUtil.readLines("example.txt", "UTF-8", line -> line.startsWith("INFO")); System.out.println(lines); // Output: List of lines starting with "INFO" True to its mission, Hutool continues to reduce

No more post‑copy loops.

, bringing major upgrades to the Hutool Java library Ecosystem . This update focuses on expanding Artificial Intelligence platform integrations , refining core security utility methods , and introducing a highly specialized recyclable batch thread pool .

Drastically reduces GC overhead during heavy multi-threaded batch operations. Enhanced DesensitizedUtil with Passport Number masking.

Copying properties is routine. But what if you need to transform a value mid‑copy? Enter BeanUtil.copyProperties(source, target, (srcField, targetField) -> if ("password".equals(targetField)) return "***"; return srcField; ) ;

: Data compliance requires masking Personally Identifiable Information (PII). DesensitizedUtil now features an automatic mechanism to strip and protect international passport strings safely before logging them.
