使用 GraalVM 运行 Spring Native 时出现“无法加载可选框架类”错误

问题描述 投票：0回答：1

使用 Spring-native (Spring-boot3.0.5)，我尝试覆盖 

ClassPathBeanDefinitionScanner
类，但在使用 AOT 时出现运行时错误。

我定义了一个扩展的新类

ClassPathBeanDefinitionScanner
:

lang=java

public class RpcComponentScanner extends ClassPathBeanDefinitionScanner {

    public RpcComponentScanner(BeanDefinitionRegistry registry) {
        super(registry);
    }

    public void registerDefaultFilters() {
        this.addIncludeFilter(new AnnotationTypeFilter(MyRPCService.class));
    }

    public Set<BeanDefinitionHolder> doScan(String... basePackages) {
        Set<BeanDefinitionHolder> beanDefinitions = super.doScan(basePackages);
        return beanDefinitions;
    }  

 // ....... other codes
}

并实施

BeanFactoryPostProcessor
；当 Spring 应用程序启动时，该类将调用 
RpcComponentScanner.scan()
。

@Component
public class RpcComponentProcesser implements BeanFactoryPostProcessor, BeanPostProcessor, ApplicationContextAware {

   @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
        String basePackage ="com.demo";// value is "com.demo"
         
        if (!(beanFactory instanceof BeanDefinitionRegistry)){
            return;
        }

        RpcComponentScanner scanner = new RpcComponentScanner((BeanDefinitionRegistry) beanFactory);
        scanner.setResourceLoader(applicationContext);

       scanner.scan(RpcConstants.COMMA_SPLIT_PATTERN.split(basePackage));// This line runs success in JVM,but failed in AOT.The code compile successful with graalvm,but startup with exceptions 
    }

 // ....... other codes

}

我已经在

RpcComponentProcesser
类中注册了
RpcComponentScanner
和
MyRPCService
、
RuntimeHints
，它实现了
RuntimeHintsRegistrar
。

当我删除此行时：

scanner.scan(RpcConstants.COMMA_SPLIT_PATTERN.split(basePackage));

应用程序运行成功。

spring spring-data-jpa graalvm-native-image spring-native

那是因为 

PersistenceAnnotationBeanPostProcessor
需要运行时功能，例如反射和动态代理生成。

首先，我会尝试使用 GraalVM 跟踪代理，如果它没有帮助，您可以尝试将其替换为 Spring Native 中的另一个 

BeanPostProcessor
。
