我设法为我的 springboot fat jar 构建了 native-image，但是java.lang.NoSuchMethodException: com.my.passgenerator.PassGeneratorApplication.<init>()当我运行它时它会抛出异常：“”。我试图添加一个默认构造和一个空的 init() 方法，但都失败了。如何克服此异常并运行此本机映像？

以下是完整的日志：

compile.sh从脚本构建方法切换到本答案中描述的 native-image-maven-plugin时，我遇到了同样的错误。这里的关键错误是No default constructor found消息，问题发生在 Spring Feature 在native-image-maven-plugin执行内部工作时：

Found no META-INF/spring.components -> synthesizing one...
    Computed spring.components is 
    vvv
    ^^^
    Registered 0 entries
    Configuring initialization time for specific types and packages:
    #87 buildtime-init-classes   #23 buildtime-init-packages   #33 runtime-init-classes

Spring 严重依赖于运行时的类路径扫描，通常可以在其中找到您的@SpringBootApplication或带注释的组件。@Component但是让 Spring 应用程序与 GraalVM Native Image 一起工作是一个很大的挑战，因为这里不再可能进行运行时类路径扫描。

Spring Feature spring-graalvm-native因此尝试处理META-INF/spring.components文件或在内存中计算。后者现在不能使用native-image-maven-plugin工作。要解决此问题，您需要在 pom.xml 中向spring-context-indexer添加显式依赖项（请参阅此处的完整示例）：

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-indexer</artifactId>
    </dependency>

当前的Spring Feature 文档还告诉我们应该使用的这种依赖关系。如果你添加spring-context-indexer到你的pom.xml，它将创建一个target/classes/META_INF/spring.components包含你的@SpringBootApplication注释类的文件：

com.my.passgenerator.PassGeneratorApplication=org.springframework.stereotype.Component

此外，您的构建输出应说明该文件已被处理，并且已像这样注册了一个条目：

Processing META-INF/spring.components files...
Registered 1 entries
Configuring initialization time for specific types and packages:
#87 buildtime-init-classes   #23 buildtime-init-packages   #33 runtime-init-classes

如果您添加更多@Component带注释的类，该文件也将包含它们，并且还将在native-image构建过程中注册。成功构建 Maven 后，您的 Spring Boot 原生应用程序应按预期启动。有关更多信息，您还可以查看有关使用 native-image-maven-plugin for Spring Boot GraalVM Native Image builds 的博客文章。
