Question

我试图使用Spring Boot和GraalVM Native Image创建一个示例应用程序，但是，由于添加了Springdoc的依赖项，由于以下原因，生成的可执行文件不再起作用：

<?php
echo "<br>1 ".$_SERVER["HTTPS"];
echo "<br>2 ".$_SERVER["SERVER_PORT"];
echo "<br>3 ".$_SERVER["HTTP_X_FORWARDED_PROTO"];
echo "<br>4 ".$_SERVER["HTTP_X_FORWARDED_SSL"];
echo "<br>5 ".$_SERVER["HTTP_HTTPS"];
echo "<br>6 ".$_SERVER["REQUEST_SCHEME"];
?>

<html>
<body>
<br>
Just cruising
</body>
</html>

我当前的依赖项是：

在我添加SpringDoc之前，一切工作正常。已经尝试将一些springdoc软件包添加到--initialize-at-build时，但是没有成功。

我正在使用com.github.ayltai.spring-graalvm-native-plugin处理gradle任务，我的依赖项是：

dependencies {
    implementation ('org.springframework.boot:spring-boot-starter-web') {
        exclude group : 'org.apache.tomcat.embed', module : 'tomcat-embed-websocket'
    }
    implementation("org.springframework.boot:spring-boot-starter-actuator")
    // Lombok
    compileOnly("org.projectlombok:lombok")
    annotationProcessor("org.projectlombok:lombok")

    testCompileOnly("org.projectlombok:lombok")
    testAnnotationProcessor("org.projectlombok:lombok")

    // https://mvnrepository.com/artifact/org.slf4j/jcl-over-slf4j
    implementation('org.slf4j:jcl-over-slf4j:2.0.0-alpha1')
    implementation('org.springdoc:springdoc-openapi-webmvc-core:1.4.4')
}

任何提示将不胜感激。

目前，还没有正式的spring gradle插件，因为spring应用程序与graalVM的集成仍处于实验模式，并且可能会面临很多其他问题。

您遇到的错误是因为您的本机配置映像不完整。

您可以使用spring-graalvm-native，它由Spring团队支持，并且与springdoc-openapi一样具有吸引力：

用法在这里进行了解释：

https://repo.spring.io/milestone/org/springframework/experimental/spring-graalvm-native-docs/0.7.1/spring-graalvm-native-docs-0.7.1.zip!/reference/index.html#_guides

对于您要提及的类，您应该在reflect-config.json中：

{
"name": "org.springdoc.core.CacheOrGroupedOpenApiCondition",
"methods": [
  {
    "name": "<init>",
    "parameterTypes": []
  }
]
}

在resource-config.json上：

{"pattern":"\\Qorg/springdoc/core/CacheOrGroupedOpenApiCondition$OnCacheDisabled.class\\E"}, 
{"pattern":"\\Qorg/springdoc/core/CacheOrGroupedOpenApiCondition$OnMultipleOpenApiSupportCondition.class\\E"}, 
{"pattern":"\\Qorg/springdoc/core/CacheOrGroupedOpenApiCondition.class\\E"}

GraalVM本机映像因Springdoc依赖性而失败
