window下使用GreaalVM编译springboot存在很多坑，主要是配置MSVC

可以参考spring官网：https://docs.spring.io/spring-native/docs/0.12.1/reference/htmlsingle/#_build_the_native_application_2

下载GreaalVM

下载GreaalVM地址：https://github.com/graalvm/graalvm-ce-builds/releases
2022年11月20日最新版22.3.0，所属的openjdk版本是17.0.5
解压到C:\Program Files\graalvm-ce-java17-22.3.0
配置它到环境变量：（替换原jdk环境变量）

创建springboot项目

springboot项目是2.7.5，使用IDEA创建springboot项目，删除测试文件。注意某些依赖无法打包源生
Maven如下：

    </profiles>

</project>

编写一个controller

package top.lingkang.graalvmdemo.controller;

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

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @author lingkang
 * Created by 2022/11/20
 */
@RestController
public class WebController {
    private SimpleDateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    @GetMapping("/")
    public Object index(){
        return "hi, "+format.format(new Date());
    }
}

运行项目无任何报错

GreaalVM打包

在window下，打包钱需要配置MSVC。
我电脑中已经下载了 Visual Studio 2022 并且已经安装了最新的MSVC

接下来配置MSVC

配置MSVC

找到MSVC的安装目录，我的被VS安装到了 C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.31.31103

配置LIB环境变量

C:\Users\Administrator>echo %LIB%
C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\um\x64;C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\ucrt\x64;C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.31.31103\bin\Hostx64\x64;C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.31.31103\lib\x64;

你可以复制替换系统版本和MSVC位置

其中10.0.19041.0为你的window版本，可以去到对应路径C:\Program Files (x86)\Windows Kits\10中查找

配置INCLUDE环境变量

C:\Users\Administrator>echo %INCLUDE%
C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\ucrt;C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\um;C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\shared;C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.31.31103\include

你可以复制替换系统版本和MSVC位置
