问题：

springboot fat jar的graalvm本机映像在运行时抛出NoSuchMethodException xxx.()

窦华晖

2023-03-14

我设法为springboot fat jar构建了本机映像，但当我运行它时，它抛出了异常：“java.lang.NosuchMethodException:com.my.PassGenerator.PassGeneratorApplication. ()”。我尝试添加一个默认构造和一个空的init（）方法，但都失败了。如何克服此异常并使本机映像运行？

以下是完整日志：

在从compile.sh脚本构建方法切换到本so答案中描述的native-image-maven-plugin时，我也遇到了同样的错误。这里的关键错误是no default constructorfound消息，问题发生在Spring特性在native-image-maven-plugin执行中工作时：

Spring严重依赖于运行时的类路径扫描，在运行时可以正常找到@SpringBootApplication或@component注释组件。但是让Spring应用程序使用GraalVM本机映像是一个很大的挑战，因为运行时类路径扫描在这里已经不可能了。

因此，Spring特性spring-graalvm-native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。要解决这个问题，您需要在pom.xml中向spring-context-indexer添加一个显式的依赖项（请参阅此处的一个完全工作的示例）：

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

当前的Spring特性文档也告诉了我们应该使用的这种依赖关系。如果您将spring-context-indexer添加到pom.xml中，它将创建一个文件target/classes/meta_inf/spring.components，其中包含@SpringBootApplication注释类：

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

此外，您的构建输出应该声明，文件已经被处理，并且一个条目已经注册，如下所示：
