This exception only throw in the native-image. When running spring-aot-mode without native-image, this exception will not be thrown.

Through adding logs and debugging, found that the root cause is that the JDK proxy object cannot perform the 'getMethod' operation in the native-image, it will threw the NoSuchMethodException, resulting in the method obtained by the 'ClassUtils. getMostSpecificMethod (...)' method is not as expected.

For example: jdkProxy.getClass().getMethod(methodName); will throw NoSuchMethodException in native-image, even if the method exists in the proxied interface.

I also report another issue: https://github.com/oracle/graal/issues/6079

The simplest example:

https://github.com/wangliang181230/example__spring-projects_spring-boot_issue-34388

Classes:

My FeignClient

@FeignClient(name = "openfeign-example", url = "https://httpbin.org", contextId = "openfeign-example")
public interface HttpbinClient {

    @GetMapping("/delay/3")
    String delay();

    @GetMapping("/status/500")
    String status500();


    @GetMapping("/get")
    String get();

}

My Aspect

@Aspect
@Component
public class SentinelResourceAspect extends AbstractSentinelAspectSupport {

    private static final Logger LOGGER = LoggerFactory.getLogger(SentinelResourceAspect.class);


    @Pointcut("@annotation(com.alibaba.csp.sentinel.annotation.SentinelResource)")
    public void sentinelResourceAnnotationPointcut() {
    }

    @Around("sentinelResourceAnnotationPointcut()")
    public Object invokeResourceWithSentinel(ProceedingJoinPoint pjp) throws Throwable {
        LOGGER.info("Start aspect");

        // do something......
    }
}

Modified `AspectJExpressionPointcut` and print error log:

I modified the AspectJExpressionPointcut to catch the exception and print exception log. Otherwise, the application will not start.

The modified `AspectJExpressionPointcut`:

public class AspectJExpressionPointcut extends AbstractExpressionPointcut
        implements ClassFilter, IntroductionAwareMethodMatcher, BeanFactoryAware {

    ......

    private ShadowMatch getTargetShadowMatch(Method method, Class<?> targetClass) {

        if (targetClass.getName().startsWith("jdk.")) {
            // In `native image`,    the value of `targetMethod.getDeclaringClass()` is the FeignClient interface: `HttpbinClient.class`,
            // In 'spring-aot-mode', the value of `targetMethod.getDeclaringClass()` is the proxy type: `jdk.proxy4.$Proxy46`.
            logger.info("\r\n    getTargetShadowMatch:" + " targetClass: " + targetClass.getName() + ", targetMethod: " + targetMethod.toGenericString()

            );
        }

        if (targetMethod.getDeclaringClass().isInterface()) {
            // Try to build the most specific interface possible for inherited methods to be
            // considered for sub-interface matches as well, in particular for proxy classes.
            // Note: AspectJ is only going to take Method.getDeclaringClass() into account.
            Set<Class<?>> ifcs = ClassUtils.getAllInterfacesForClassAsSet(targetClass);
            if (ifcs.size() > 1) {
                Class<?>[] interfaces = ClassUtils.toClassArray(ifcs);
                try {
                    Class<?> compositeInterface = ClassUtils.createCompositeInterface(
                            interfaces, targetClass.getClassLoader());
                    targetMethod = ClassUtils.getMostSpecificMethod(targetMethod, compositeInterface);
                }
                catch (IllegalArgumentException ex) {
                    // Implemented interfaces probably expose conflicting method signatures...
                    // Proceed with original target method.
                }
                catch (Throwable t) {
                    // Catch the exception, and print the log
                    // Otherwise, the application will not start
                    logger.error(Arrays.toString(interfaces) + " for class '"+targetClass.getName()+"' is createCompositeInterface failed", t);
                }
            }
        }
        return getShadowMatch(targetMethod, method);
    }

    ......

Comment From: wilkinsona

I think this should have been fixed by https://github.com/spring-projects/spring-framework/issues/29519. Please test with the latest version of Spring Boot. If the problem still occurs, please open a Spring Framework issue.

Comment From: wangliang181230

Fixed, Thanks.
