英文:
Spring Boot: GraalVM Native Image Support
问题
Sure, here's the translated content you requested:
我有一个Spring Boot项目，最初使用的是Java 11的2.7.6版本，当前正在添加[GraalVM原生镜像支持][1]，按照[使用Buildpacks构建原生镜像][2]的文档进行操作。我已经将版本更改为Java 17的3.1.0版本，并修改了pom.xml。我还对spring-data-jpa进行了更改，重构了导入语句，现在可以运行该应用程序。
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.1.0</version>
</parent>
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
</plugin>
我对添加GraalVM的理解是它将加快应用程序的启动时间并减小jar文件或应用程序的Docker镜像的构建大小。以下是比较结果。
在GraalVM之前：
应用程序启动时间约为7秒
运行 mvn clean install 的时间约为15秒
Jar文件大小约为61MB
在GraalVM之后：
应用程序启动时间约为2秒
运行 mvn clean install -Pnative 的时间约为12秒
Jar文件大小约为77MB
问题如下：
-
我可以看到应用程序启动时间的性能提升，这很好，但是jar文件的大小已经增加，应该小于约61MB。
-
我是否使用了正确的GraalVM构建命令，即使用
mvn clean install -Pnative？ -
在文档中有如下说明，我是否需要在pom.xml中添加任何内容？
用于镜像的构建器是paketobuildpacks/builder:tiny。它具有小的足迹和减小的攻击面，但如果需要，您也可以使用paketobuildpacks/builder:base或paketobuildpacks/builder:full，以在镜像中获得更多工具。
如果我在spring-boot-maven-plugin的配置中添加以下内容，我会收到共享的错误消息：
<image>
<buildpacks>
<buildpack>paketobuildpacks/builder:full</buildpack>
</buildpacks>
<env>
<BP_NATIVE_IMAGE>true</BP_NATIVE_IMAGE>
</env>
</image>
class org.springframework.boot.maven.Image无法转换为class org.springframework.boot.maven.FilterableDependency（org.springframework.boot.maven.Image和org.springframework.boot.maven.FilterableDependency位于加载器org.codehaus.plexus.classworlds.realm.ClassRealm @6228d0bd的未命名模块中）
更新：
当我运行 mvn -Pnative native:compile 时，我收到以下错误。
错误：应该在运行时初始化的类在图像构建期间被初始化：
在构建时意外初始化了org.apache.commons.logging.LogFactory。要查看为什么初始化了org.apache.commons.logging.LogFactory，请使用--trace-class-initialization=org.apache.commons.logging.LogFactory

I have a Spring Boot project which was initially using version 2.7.6 with Java 11 and currently, I am adding the [GraalVM Native Image Support][1] by following the documentation with [Building a Native Image Using Buildpacks][2] option. I have changed the version to 3.1.0 with Java 17 and modified the pom.xml. I have also done the changes regarding spring-data-jpa and refactored the import statements and now I am able to run the application.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>3.1.0</version>
</parent>
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
</plugin>
My understanding of adding the GraalVM is that it will make the application start-up time faster and reduce the build size of jar file or the docker image of an application. Below is the comparison.
**Before GraalVM:** <br>
Application start in ~7s <br>
Time to run `mvn clean install` ~15s <br>
Jar file size ~61MB
**After GraalVM:** <br>
Application start in : ~2s <br>
Time to run `mvn clean install -Pnative` ~12s <br>
Jar file size ~77MB
**Questions are:**
1. I can see the performance on the application startup time which is good, however jar file size has increased which is supposed to be less than ~61MB
2. Does I am using the correct command for build with GraalVM by using `mvn clean install -Pnative`
3. In the documentation there is note as below, do I need to add anything in the pom.xml?
> The builder used for the images is paketobuildpacks/builder:tiny. It
> has small footprint and reduced attack surface, but you can also use
> paketobuildpacks/builder:base or paketobuildpacks/builder:full to have
> more tools available in the image if required.
If I do add below in the configurations of spring-boot-maven-plugin, I am getting the shared error message
<image>
<buildpacks>
<buildpack>paketobuildpacks/builder:full</buildpack>
</buildpacks>
<env>
<BP_NATIVE_IMAGE>true</BP_NATIVE_IMAGE>

**class org.springframework.boot.maven.Image cannot be cast to class org.springframework.boot.maven.FilterableDependency (org.springframework.boot.maven.Image and org.springframework.boot.maven.FilterableDependency are in unnamed module of loader org.codehaus.plexus.classworlds.realm.ClassRealm @6228d0bd)**
----------
**UPDATE:**
When I do run `mvn -Pnative native:compile` I am getting the below error.
**Error: Classes that should be initialized at run time got initialized during image building:

我可以看到应用程序启动时间的性能很好，但是jar文件大小已经增加，应该小于~61MB。
本地镜像是一个特定平台的二进制文件，可以在没有JVM的情况下执行。jar文件的大小并不重要。
我是否正在使用正确的命令来使用GraalVM构建，使用mvn clean install -Pnative？
如果你想要使用构建包来创建一个包含本地可执行文件的容器镜像，你应该运行 `mvn -Pnative spring-boot:build-image`。
如果你想在你的机器上直接构建本地可执行文件，你应该运行 `mvn -Pnative native:compile`。你还需要添加本地构建工具Maven插件：
```xml
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
</plugin>
如果我在spring-boot-maven-plugin的配置中添加以下内容，我会得到共享的错误消息。
只看到配置片段并没有堆栈跟踪，很难确定，但我怀疑你将配置放在了错误的标签中。它应该类似于这样：
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<image>
<buildpacks>
<buildpack>paketobuildpacks/builder:full</buildpack>
</buildpacks>
<env>
<BP_NATIVE_IMAGE>true</BP_NATIVE_IMAGE>
</env>
</image>
</configuration>
</plugin>
英文:
> I can see the performance on the application startup time which is good, however jar file size has increased which is supposed to be less than ~61MB
A native image is a platform-specific binary that can be executed without a JVM. The size of the jar file isn't relevant.
> Does I am using the correct command for build with GraalVM by using mvn clean install -Pnative
If you want to use buildpacks to create a container image that contains a native executable you should run mvn -Pnative spring-boot:build-image.
If you want to build a native executable directly on your machine, you should run mvn -Pnative native:compile. You also need to add the Native Build Tools Maven plugin:
<plugin>
<groupId>org.graalvm.buildtools</groupId>
<artifactId>native-maven-plugin</artifactId>
</plugin>
> If I do add below in the configurations of spring-boot-maven-plugin, I am getting the shared error message
It's hard to tell with only a snippet of configuration and no stack trace but I suspect you've placed the configuration within the wrong tags. It should look something like this:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<image>
<buildpacks>
<buildpack>paketobuildpacks/builder:full</buildpack>
</buildpacks>
<env>
<BP_NATIVE_IMAGE>true</BP_NATIVE_IMAGE>
</env>
</image>
</configuration>
</plugin>
