The purpose of this article is to share with you about the common tools of the java toolkit Hutool. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Brief introduction

Hutool is a small and complete Java tool class library, which is encapsulated by static methods to reduce the learning cost of related API and improve work efficiency. It covers all aspects of the underlying code of Java development. It is not only a sharp tool to solve small problems in large-scale project development, but also an efficiency responsibility in small-scale projects.

Components included in Hutool

A Java basic tool class that encapsulates JDK methods such as file, stream, encryption and decryption, transcoding, regularization, threading, XML, etc., to form various Util tool classes, and provides the following components: the module introduces hutool-aopJDK dynamic proxy encapsulation, provides aspects under non-IOC to support hutool-bloomFilter Bloom filtering, and provides some Bloom filtering hutool-cache simple cache of some Hash algorithms to implement hutool-core core. Including Bean operation, date, various Util and other hutool-cron timing task modules, providing timing task hutool-crypto encryption and decryption module similar to Crontab expression, providing symmetrical, asymmetric and abstract algorithms encapsulating hutool-dbJDBC encapsulated data operation, hutool-dfa based on ActiveRecord idea hutool-dfa multi-keyword search hutool-extra expansion module based on DFA model Third-party encapsulation (template engine, mail, Servlet, QR code, Emoji, FTP, word segmentation, etc.) hutool-http Http client encapsulation based on HttpUrlConnection hutool-log automatic log recognition implementation of log facade hutool-script script encapsulation For example, Javascripthutool-setting 's more powerful Setting configuration file and Properties encapsulation hutool-system system parameter call encapsulation (JVM information, etc.) hutool-jsonJSON implementation of hutool-captcha picture verification code implementation of hutool-poi encapsulation for Excel in POI hutool-socket Java-based NIO and AIO Socket encapsulation
