Hutool 39 ((better)) Jun 2026

5.8.44 带来的重要新特性包括：

Characterized by its slogan, "A set of tools that keep Java sweet," Hutool simplifies daily development. Whether utilizing its mature standard libraries or leveraging specific sub-builds like version available on the Maven Repository , Hutool encapsulates the complexities of standard Java APIs into elegant, static method calls. What is Hutool?

: Enhanced the XXXToMapCopier for faster object-to-map conversions.

The db module now supports a global FetchSize configuration. This helps developers prevent Out-Of-Memory (OOM) situations during massive table sweeps by chunking result processing at the JDBC boundary. hutool 39

A lightweight JDBC wrapper that simplifies CRUD operations and database interaction without the overhead of Hibernate or MyBatis [5].

: Introduced the RecyclableBatchThreadPoolExecutor , designed specifically to process high-throughput batch sequences while safely recalling threaded workloads without leaks. 3. Enterprise Connectivity ( hutool-http & hutool-db )

To use the modern version (Hutool 5.8+), add the following to your project. A lightweight JDBC wrapper that simplifies CRUD operations

Hutool gives you , one method call , zero checked exceptions (usually).

Provides safe mathematical calculations, precision parsing, and number formatting.

: Introduced global FetchSize settings to optimize data retrieval during large queries. allowing developers to execute symmetric (AES

import cn.hutool.json.JSONUtil; import cn.hutool.json.JSONObject; import cn.hutool.json.JSONArray;

A simplified wrapper for standard cryptography routines, allowing developers to execute symmetric (AES, DES), asymmetric (RSA), and hashing algorithms (MD5, SHA-256) seamlessly.

Securing Personally Identifiable Information (PII) data safely without writing custom regular expressions:

While early iterations like the laid the foundation for the library's fluent API design, the platform has underwent massive architectural upgrades. Organizations running legacy microservices may still see 3.x or 4.x versions specified in older pom.xml files, but modern production environments prioritize newer lifecycles due to security patches and language feature changes.
