Introduction

Hutool is a feature-rich and easy-to-use Java tool library . Through the use of many practical tool classes, it aims to help developers complete various development tasks quickly and conveniently. These encapsulated tools cover a series of operations such as strings, numbers, collections, encodings, dates, files, IO, encryption, database JDBC, JSON, HTTP clients, etc., and can meet various development needs.

?The origin of the name Hutool

Hutool = Hu + tool, which is an open source library stripped of the underlying code of the original company project. "Hu" represents the company name, and tool represents the tool. Hutool is homophonic for "confused". On the one hand, it is concise and easy to understand, and on the other hand, it means "it is rare to be confused".

?Hutool concept

Hutool is both a tool set and a knowledge base. We never boast of original code. Most of the tool classes are ported , so:

You can introduce and use it, or you can copy and modify it for use without marking any information . You just hope that bugs can be reported back in time.
We strive to improve Chinese annotations, provide a good learning environment for source code learners, and strive to be understandable by everyone.

Contains components

A Java basic tool class that encapsulates JDK methods such as files, streams, encryption and decryption, transcoding, regularization, threads, XML, etc., to form various Util tool classes, and also provides the following components:

module	introduce
hutool-aop	JDK dynamic proxy encapsulation provides aspect support under non-IOC
hutool-bloomFilter	Bloom filtering, providing Bloom filtering of some Hash algorithms
hutool-cache	Simple cache implementation
hutool-core	Core, including Bean operations, dates, various Utils, etc.
hutool-cron	Scheduled task module, providing scheduled tasks similar to Crontab expressions
hutool-crypto	Encryption and decryption module, providing symmetric, asymmetric and digest algorithm encapsulation
hutool-db	JDBC encapsulated data operations, based on ActiveRecord ideas
hutool-dfa	Multi-keyword search based on DFA model
hutool-extra	Extension module, encapsulating third parties (template engine, email, Servlet, QR code, Emoji, FTP, word segmentation, etc.)
hutool-http	Http client encapsulation based on HttpUrlConnection
hutool-log	Automatically identify the log facade implemented by logs
hutool-script	Script execution encapsulation, such as Javascript
hutool-setting	More powerful Setting configuration file and Properties encapsulation
hutool-system	System parameter call encapsulation (JVM information, etc.)
hutool-json	JSON implementation
hutool-captcha	Image verification code implementation
hutool-poi	Encapsulation of Excel and Word in POI
hutool-socket	Java-based Socket encapsulation of NIO and AIO
hutool-jwt	JSON Web Token (JWT) encapsulation implementation

Each module can be introduced individually according to requirements, or all modules can be introduced by introducing hutool-all .

?Install

?Maven

Add the following content to the dependencies of the project's pom.xml:

< dependency >
    < groupId >cn.hutool</ groupId >
    < artifactId >hutool-all</ artifactId >
    < version >5.8.34</ version >
</ dependency >

?Gradle

 implementation 'cn.hutool:hutool-all:5.8.34'

?Download jar

Click the following link to download hutool-all-XXXjar :

Maven central repository

?️Note that Hutool 5.x supports JDK8+ and has not been tested on the Android platform. It cannot guarantee that all tool classes or tool methods are available. If your project uses JDK7, please use Hutool 4.x version (no longer updated)

?Compile and install

Visit Hutool's Gitee homepage: https://gitee.com/dromara/hutool Download the entire project source code (either v5-master or v5-dev branch) and then enter the Hutool project directory to execute:

./hutool.sh install

Then you can use Maven to import it.

?Branch description

Hutool's source code is divided into two branches, with the following functions:

branch	effect
v5-master	The main branch, the branch used by the release version, is consistent with the jar submitted by the central library and does not receive any PR or modification.
v5-dev	Development branch, defaults to the SNAPSHOT version of the next version, accepts modifications or pr

?Provide bug feedback or suggestions

When submitting feedback, please indicate the JDK version, Hutool version and related dependent library versions you are using.

Gitee issue
Github issue

?Steps to contribute code

Fork the project to your own repo on Gitee or Github
Clone the forked project, which is your project, to your local computer
Modify the code (remember to modify the v5-dev branch)
After committing, push to your own library (v5-dev branch)
Log in to Gitee or Github and you will see a pull request button on your homepage. Click it, fill in some description information, and then submit.

?Principles followed by PR

Hutool welcomes anyone to contribute to Hutool and contribute code, but the maintainer is an obsessive-compulsive disorder patient. In order to take care of patients, the PR (pull request) that needs to be submitted must comply with some specifications. The specifications are as follows:

The annotations are complete. In particular, each new method should be marked with method description, parameter description, return value description and other information in accordance with Java documentation specifications. Please add unit tests if necessary. If you like, you can also add your name.
Hutool's indentation follows Eclipse's ( ~~Don't tell me how easy it is to use IDEA. The maintainers are too lazy to learn.~~ , IDEA is really good, I feel much more comfortable after changing the Eclipse shortcut keys) The default (tab) indentation, so please abide by it (don’t argue with me about spaces and tabs, this is a patient habit).
Do not use third-party library methods for newly added methods. Hutool follows the no-dependency principle (unless adding method tools in the extra module).
Please pull request to the v5-dev branch. Hutool used a new branch after version 5.x: v5-master is the main branch, which means that the version of the central library has been released. This branch does not allow PR or modification.
Please don't be surprised if we close your issue or PR. This is our way of keeping the issue clean. You can still continue the discussion and we will reopen it when there are results from the discussion.
