feilong 的历史

since 2008, 起初应对开发过程中不断重复的代码进行了封装,进而在公司内部推广

:dragon: Maven使用配置

feilong 自从3.0.0开始,发布中央仓库 https://search.maven.org/artifact/com.github.ifeilong/feilong

maven 配置


Gradle 配置



点击 https://repo1.maven.org/maven2/com/github/ifeilong/feilong/ 链接,下载 feilong.jar即可:


  • feilong 3 需要 JDK8+,对Android平台没有测试,不能保证所有工具类或工具方法可用。
  • 如果你的项目使用 JDK7,请使用 feilong-core 2.1.0 版本

How to install?
