1、简介Leveldbjni提供LevelDB的JAVA接口。本文的最终目标是编译生成leveldbjni-all-1.8.jar包。2、基础环境类别子项版本获取地址(方法)华为云虚拟机KC1（920）--OSCentOS7.5Kernel4.14软件包snappy1.1.5https://github.com/google/snappy/archive/1.1.5.tar.gz leveldbV1.20https://github.com/google/leveldb/archive/v1.20.tar.gzleveldbjnimasterhttps://github.com/fusesource/leveldbjni.git 3、依赖安装Leveldbjni的编译需要maven，因此先设置好OpenJDK及maven。此处我们在centos7的容器中进行。https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/download/jdk8u222-b10/OpenJDK8U-jdk_aarch64_linux_hotspot_8u222b10.tar.gz https://archive.apache.org/dist/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz将如上链接中的两个tar包解压到固定位置，如/opt/，待后续使用。1) 拉起容器将解压位置挂载到/root,可以不用修改maven的配置文件（默认为用户HOME目录的.m2/repository），可将缓存持久化的同时，避免maven写docker读写层。bash-4.2# docker
