graalvm把springboot 3.0应用编译为原生应用_graalvm native support >= 3.0.0-m1

之前的文章《Graalvm 安装和静态编译（https://blog.csdn.net/penngo/article/details/128006244）》介绍了graalvm的安装和环境配置，普通java应用、swing应用、javafx应用编译为原生的方法。
本文介绍springboot应用编译为原生的方法，graalvm的安装配置参考前文。

1、GraalVM Native Support依赖

GraalVM Native Support版本要求Spring Boot >= 3.0.0-M1。
https://docs.spring.io/spring-boot/docs/current/reference/html/native-image.html#native-image

native-build-toolsMaven插件：https://graalvm.github.io/native-build-tools/latest/index.html

可以在https://start.spring.io/快速生成项目：

创建一个简单的springboot例子应用。
Main.java

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, args);
    }
}

import java.util.Date;

@Controller
public class IndexController {

    @RequestMapping("/index")
    @ResponseBody
    public Result index() {

        return Result.create("测试");
    }

2、编译为原生应用

GraalVM Native Support支持两种方式编译：编译为docker镜像或原生应用文件。

2.1、编译为docker镜像

需要安装docker服务，可以参考文章《docker、docker-compose安装和常用命令https://blog.csdn.net/penngo/article/details/128164507》。
编译为镜像文命令：

mvn -Pnative spring-boot:build-image
1

启动服务：

docker run --rm -p 8080:8080 docker.io/library/springboot_graalvm_test:1.0.0
1

2.2、编译为原生应用文件

需要在本地系统中配置graalvm，可以参考《Graalvm 安装和静态编译（https://blog.csdn.net/penngo/article/details/128006244）》。本文是在win10上编译。
编译命令：

mvn -Pnative clean native:compile
1

启动服务：

双击springboot_graalvm_test.exe运行
