【问题描述】：

我正在尝试使用 spring boot 和 GraalVM Native Image 创建一个示例应用程序，但是一旦我添加了 Springdoc 的依赖项，生成的可执行文件就不再工作了，原因如下：

我目前的依赖是：

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')

在我添加 SpringDoc 之前一切正常。 已经尝试将一些springdoc包添加到--initialize-at-build-time，但没有成功。

我正在使用 com.github.ayltai.spring-graalvm-native-plugin 来处理 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。

【参考方案1】：

由于v1.5.9springdoc-openapi fully supports GraalVM 和 spring-native。

无需额外配置。

【讨论】：

您好，感谢您的意见！我已经在使用 spring-graalvm-native。但是，添加资源配置似乎会破坏本机映像编译：Fatal error:java.util.MissingFormatArgumentException: Format specifier '%5c'

好的，我正在使用的 gradle 插件似乎有问题。我只是将所有内容都切换到 maven，它开始给出一些不同的错误 - 我在编写时向资源配置添加了更多内容，它似乎正在工作（或至少部分修复了一些问题）。您的回复让我更加了解 json 以及何时/如何使用它们。
