# 静态编译需要单独安装musl、zlib
https://www.graalvm.org/jdk21/reference-manual/native-image/guides/build-static-executables/
$ apt update
$ apt install -y build-essential zlib1g-dev maven
分割文件
$ split -b 50M graalvm-community-jdk-21.0.2_linux-x64_bin.tar.gz -d graalvm-community-jdk-21.0.2_linux-x64_bin.tar.gz_
合并文件
$ ls -ltrh
$ cat graalvm-community-jdk-21.0.2_linux-x64_bin.tar.gz_* > graalvm-community-jdk-21.0.2.tar.gz
解压文件
$ tar -zxvf graalvm-community-jdk-21.0.2.tar.gz -C /usr/local/ --transform="s/graalvm-community-openjdk-21.0.2+13.1/graalvm/g"
$ sed -i '$a export PATH=/usr/local/graalvm/bin:$PATH' ~/.bashrc
$ source ~/.bashrc
$ java --version
$ native-image --version
$ mvn --version

Git

$ apt update
$ apt install -y git
$ git --version
$ git config --global user.name "renlm"
$ git config --global user.email "renlm@21cn.com"
$ ssh-keygen -m PEM -t rsa -b 2048 -C "renlm@21cn.com"
$ cat ~/.ssh/id_rsa.pub
$ git clone -b master --single-branch git@gitee.com:renlm/config-server.git
$ cd ./config-server

输出编译配置

$ docker run -it --rm -p 7001:7001 -v /root/.m2:/root/.m2 -v /root/config-server:/build ubuntu:22.04 bash
root@b4da32ed34ce:/# cd /build
root@b4da32ed34ce:/build# source ./graalvm/install.sh

静态编译
root@b4da32ed34ce:/build# mvn clean -Pnative -P dev native:compile
root@b4da32ed34ce:/build# ldd target/config-server
    not a dynamic executable

测试覆盖
root@b4da32ed34ce:/build# mvn clean package -P dev
root@b4da32ed34ce:/build# java -agentlib:native-image-agent=config-output-dir=./output -jar target/config-server.jar

将输出拷贝到resources/META-INF/native-image
新建native-image.properties，设置构建参数
自动加载
