1.GraalVM

GraalVM (https://www.graalvm.org/) 是一个高性能的JDK，旨在加速用Java和其他JVM语言编写的应用程序的执行，同时还提供JavaScript，python和许多其他流行语言的运行时。

GraalVM提供了两种运行Java应用程序的方式：

在hotspot jvm上使用graal即时编译器(JIT)
作为预先编译的本机可执行文件运行

GraalVM的多语言能力使得在单个应用程序中混合多种编程语言成为可能，同时消除了外部语言的调用成本。

2.Windows平台安装和配置GraalVM

Windows平台环境安装和配置比较复杂

2.1 安装Visual Studio

Visual Studio（特别是其中的 Visual C++ 工具）在 Windows 系统上提供了 C/C++ 编译器和相关工具链，它们是用来编译和链接本地代码的。当使用 GraalVM 在 Windows 上构建本地可执行文件时，需要依赖 Visual Studio 提供的这些编译工具来完成编译和链接的过程。

安装界面，勾选使用C++的桌面开发

等待安装完成后，测试x64 Native Tools Command Prompt for VS 2022

以管理员身份测试打开x64 Native Tools Command Prompt for VS 2022

2.2 Windows安装GraalVM并配置

打开社区版GraalVM下载的GitHub页面
https://github.com/graalvm/graalvm-ce-builds/releases

以22.3.3版Java17为例，找到22.3.3版本，分别下载Windows平台的GraalVM graalvm-ce-java17-windows-amd64-22.3.3.zip和调用底层工具的原生镜像支持工具native-image-installable-svm-java17-windows-amd64-22.3.3.jar

下载地址:

graalvm-ce-java17-windows-amd64-22.3.3.zip

https://github.com/graalvm/graalvm-ce-builds/releases/download/vm-22.3.3/graalvm-ce-java17-windows-amd64-22.3.3.zip

native-image-installable-svm-java17-windows-amd64-22.3.3.jar

https://github.com/graalvm/graalvm-ce-builds/releases/download/vm-22.3.3/native-image-installable-svm-java17-windows-amd64-22.3.3.jar

设置环境变量

将GraalVM压缩包解压到F:\graalvm-ce-java17-22.3.3，然后设置环境变量JAVA_HOME为F:\graalvm-ce-java17-22.3.3，设置环境变量PATH新增%JAVA_HOME%/bin

检查环境变量生效

java -version

安装native-image

在jar包目录打开cmd窗口，输入命令，完成安装

gu install --file ./native-image-installable-svm-java17-windows-amd64-22.3.3.jar

输入命令，测试是否安装成功

native-image

至此，Windows平台GraalVM和支持将应用打包成本地镜像的工具安装配置完成。

2.3 新建简单项目测试编译打包

打开IDEA，新建项目springboot3，JDK选择安装的graalvm-ce-java17，然后先编写一段非常简单的Java代码，然后将其编译为原生.exe可执行文件

public class Main {
    public static void main(String[] args) {
        System.out.printf("hello graalvm!");
    }
}

用Maven将项目打包为jar包

打开x64 Native Tools Command Prompt for VS 2022工具，使用底层能力运行native-image工具，将class编译为.exe。

以管理员身份打开x64 Native Tools Command Prompt for VS 2022，并CD切换到jar包所在target目录，然后执行命令

-cp 编译
-o 目标.exe文件名称

native-image -cp ./springboot3-1.0-SNAPSHOT.jar org.example.Main -o springboot3

编译完成，生成Windows平台的.exe可执行文件

打开CMD，执行exe文件，输出代码运行结果，和Java虚拟机解释执行结果相同

2.4 新建SpringBoot3项目测试编译打包

首先要在Windows下配置三个环境变量，每个人环境和位置不同，需要自己按照自己的实际情况新增或修改。

1.path

path环境变量新增以下路径

F:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.41.34120\bin\Hostx64\x64

2.lib

新建lib环境变量，并将以下路径配置进去，之间用英文分号;间隔，以下位置目录均为VS创建

F:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.41.34120\lib\x64
F:\Windows Kits\10\Lib\10.0.22621.0\ucrt\x64
F:\Windows Kits\10\Lib\10.0.22621.0\um\x64

3.INCLUDE(大写)

新建INCLUDE环境变量，并将以下路径配置进去，之间用英文分号;间隔，以下位置目录均为VS创建

F:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.41.34120\include
F:\Windows Kits\10\Include\10.0.22621.0\shared
F:\Windows Kits\10\Include\10.0.22621.0\ucrt
F:\Windows Kits\10\Include\10.0.22621.0\um
F:\Windows Kits\10\Include\10.0.22621.0\winrt

! ! !环境变量配置好后，一定要重新打开CMD窗口编译打包，使用Intellij IDEA的，一定也要重启IDEA。

接下来，编写一个简单的SpringBoot应用，并编译打包为原生.exe文件

org.example.controller.TestController

package org.example.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("test")
public class TestController {

    @GetMapping("hello")
    public String hello(String s) {
        return "hello " + s;
    }
}

org.example.Main

package org.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Main {
    public static void main(String[] args) {
        SpringApplication.run(Main.class);
    }
}

application.yml

server:
  port: 8081

接下来先用普通的编译命令将代码编译为.class文件。

然后，执行spring-boot的process-aot插件，进行编译前的前置处理。

前置处理完成后，target目录下生成了一些AOT编译相关的文件，用于指定主类的位置等

最后，运行native插件的build启动native-image，调用VS工具链将工程编译为二进制.exe文件

开始编译后等待编译完成

编译完成，得到.exe文件

运行编译成的.exe文件并测试

.exe文件很快启动，并可以正常处理http请求，虽然命令窗口打印存在问题，但是接口是能调通的，文章写到这已经很晚了，故这个问题先留着后续有空解决…

3.linux平台安装和配置GraalVM

Linux平台安装和配置GraalVM，我使用Ubuntu22进行测试

3.1 安装Linux编译工具链

编译native-image，需要安装Linux下的编译环境

sudo apt-get install build-essential libz-dev zlib1g-dev

! tips: 如果是redhat系列linux，可能需要这样安装

sudo yum install -y gcc glibc glibc-devel zlib-devel

3.2 Linux下载安装GraalVM

接下来，和Windows系统一样，下载GraalVM和native-image的Linux x64版本，我在这里还是选择和Windows一样的22.3.3版本。

下载地址仍然是 https://github.com/graalvm/graalvm-ce-builds/releases

graalvm-ce-java17-linux-amd64-22.3.3.tar.gz

https://github.com/graalvm/graalvm-ce-builds/releases/download/vm-22.3.3/graalvm-ce-java17-linux-amd64-22.3.3.tar.gz

native-image-installable-svm-java17-linux-amd64-22.3.3.jar

https://github.com/graalvm/graalvm-ce-builds/releases/download/vm-22.3.3/native-image-installable-svm-java17-linux-amd64-22.3.3.jar

将下载好的两个文件移动到/opt目录下，解压graalvm-ce-java17-linux-amd64-22.3.3.tar.gz到路径/opt并设置环境变量

解压到/opt

tar -zxvf ./graalvm-ce-java17-linux-amd64-22.3.3.tar.gz

打开/etc/profile设置环境变量

vim /etc/profile

将下面两句放在文件最末尾

export JAVA_HOME=/opt/graalvm-ce-java17-22.3.3
export PATH=$PATH:$JAVA_HOME/bin

刷新，使环境变量生效

source /etc/profile

返回/opt目录，安装native-image.jar原生镜像打包工具包，命令和Windows之前安装的命令完全相同

cd /opt

gu install --file ./native-image-installable-svm-java17-linux-amd64-22.3.3.jar

验证JAVA_HOME变量是否生效，native-image.jar是否正确安装

java -version

native-image

3.3 编译打包SpringBoot项目

首先需要安装Linux环境的maven，并设置好环境变量，然后将工程源码拷贝到/opt目录下，然后依次执行maven命令。

先用普通的编译命令将代码编译为.class文件

mvn run compile

然后，执行spring-boot的process-aot插件，进行编译前的前置处理

mvn spring-boot:process-aot

开始编译，运行native插件的build启动native-image，调用Linux底层工具链将工程编译为Linux平台的二进制文件

mvn  native:build

终端输出

编译打包完成

编译完成，得到Linux上的可执行文件

运行可执行文件，并打开浏览器访问测试，功能正常

至此，Linux平台上原生镜像编译就完成了。

4.注意事项

不是所有Java代码都支持原生编译打包，例如代码中含有反射创建对象，反射调用方法等操作会导致AOT损失动态能力，如果编译需要额外处理，需要提前告知GraalVM未来会反射调用哪些方法或构造器，例如springboot就提供了一些注解，保证AOT编译时功能正常，但不是所有框架都像Spring那样适配了AOT。
配置文件不能放进可执行文件，也需要额外处理，可以在程序代码改为相对路径读取配置文件。
