One Life needs ： In the project “util” A package friendly alternative

Two Solution

1 thought

        Hutool The goal is to use a tool approach instead of a complex piece of code , To calculate MD5 For example ：

  • 【 before 】 Open the search engine -> search “Java MD5 encryption ” -> Open a blog -> Copy and paste -> Make it easy to use
  • 【 Now? 】 introduce Hutool -> SecureUtil.md5()

2 structure

         One Java Basic tools , The file 、 flow 、 Encryption and decryption 、 transcoding 、 Regular 、 Threads 、XML etc. JDK Method to encapsulate , Make up all kinds of Util Tool class , The following components are also provided ：

modular Introduce
hutool-aopJDK Dynamic agent encapsulation , Provide non IOC Next aspect support
hutool-bloomFilter Bloon filtration , Provide some Hash Algorithm's bloom filtering
hutool-cache Simple cache implementation
hutool-core The core , Include Bean operation 、 date 、 Various Util etc.
hutool-cron Timing task module , Provide classes Crontab Expression timing task
hutool-crypto Encryption and decryption module , Provide symmetry 、 Asymmetric and digest algorithm encapsulation
hutool-dbJDBC Data operation after encapsulation , be based on ActiveRecord thought
hutool-dfa be based on DFA Multi keyword search of model
hutool-extra Extension module , Encapsulate... To a third party （ template engine 、 mail 、Servlet、 QR code 、Emoji、FTP、 Participle, etc ）
hutool-http be based on HttpUrlConnection Of Http Client encapsulation
hutool-log Automatic recognition of the log door
hutool-script Script execution encapsulation , for example Javascript
hutool-setting More powerful Setting Configuration files and Properties encapsulation
hutool-system System parameter call encapsulation （JVM Information, etc ）
hutool-jsonJSON Realization
hutool-captcha Picture verification code implementation
hutool-poi in the light of POI in Excel and Word Encapsulation
hutool-socket be based on Java Of NIO and AIO Of Socket encapsulation
hutool-jwtJSON Web Token (JWT) Encapsulation implementation

3 flow 、 primary ：

  1. Java Tool library 、 Static method encapsulation 、 Encapsulation of public classes and utility methods .
  2. Each module can be introduced separately according to the requirements , Or by introducing hutool-all Way to introduce all modules .

4 Use

First step ： In the project pom.xml Of dependencies Add the following :

<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.8.0.M4</version>
</dependency>
