我试图在控制器处理程序方法实际执行之前创建一个方面来覆盖HttpServletRequest参数。但结果是HttpServletRequest始终是RequestFacade示例，即使我在方面方法中将其替换为自定义HttpServletRequestWrapper。
代码如下：

// the annotation:
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface MyAnnotation {
}
// the aspect:
@Component
@Aspect
@Slf4j
public class MyAspect {
    @Pointcut("@annotation(com.example.springtest.annotation.MyAnnotation)")
    public void pointcut() {
    }
    @Around("pointcut()")
    public Object setHeader(ProceedingJoinPoint pjp) throws Throwable {
        var args = pjp.getArgs();
        var signature = (MethodSignature) pjp.getSignature();
        var method = signature.getMethod();
        var annotations = method.getDeclaredAnnotations();
        var need = Arrays.stream(annotations).anyMatch(a -> a.annotationType().equals(MyAnnotation.class));
        if (!need) {
            return pjp.proceed();
        }
        for (var i = 0; i < args.length; i++) {
            var arg = args[i];
            if (arg instanceof HttpServletRequest request) {
                args[i] = new HttpServletRequestWrapper(request) {
                    @Override
                    public String getHeader(String name) {
                        if (name.equalsIgnoreCase("my-header")) {
                            return "my-header";
                        } else {
                            return super.getHeader(name);
                        }
                    }
                };
            }
        }
        return pjp.proceed();
    }
}
// the bootstrap class:
@Configurable
@EnableAspectJAutoProxy
@SpringBootApplication
public class SpringtestApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringtestApplication.class, args);
    }
}
// and the controller
@RestController
public class TestController {
    private static final Logger log = LoggerFactory.getLogger(TestController.class);
    @MyAnnotation
    @GetMapping("/get-my-header")
    public String getMyHeader(HttpServletRequest request) {
        if (Objects.requireNonNull(request) instanceof HttpServletRequestWrapper) {
            log.info("is wrapper");
        } else {
            log.info("request:{}", request.getClass());
        }
        return request.getHeader("my-header");
    }
}

字符串
发生了什么事？在我替换了HttpServletRequest参数之后，是否有其他代理类示例更改了我的参数？
日志显示方面和控制器中的请求参数都是RequestFacade示例。
我还尝试创建一个服务方法，并直接将我的自定义HttpServletRequestWrapper示例发送给它。这一次参数没有改变。
