How in Runtime change annotation properties in Custom BeanPostProcessor

ENVIRONMENT:

Java 8
Srping Framework 5

SITUATION: I need to change in Runtime @GetMapping annotation attributes values.

TASK: I have my controller and durring runtime I need to change value attribute from value = {"/**"} to value = {"/method1", "/method2"}

@RestController
@RequestMapping("/api")
public class MyController {
@GetMapping(value = {"/**"}, produces = {"application/json", "text/csv"})
public ResponseEntity<?> query(HttpServletRequest request, @RequestParam Map<String, String> params) {
    ..........
}

ACTION: I added custom bean post processor and via reflection tried to change the value field of @GetMappg annotation.

@Override
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException {
    if (bean instanceof MyController) {
        Method[] methods = bean.getClass().getDeclaredMethods();
        for (int i = 0; i < methods.length; i++) {
            GetMapping currentAnnotation = AnnotationUtils.findAnnotation(methods[i], GetMapping.class);
            if (Objects.nonNull(currentAnnotation)) {
                LOGGER.debug("GetMapping annotation before:" + currentAnnotation);
                try {
                Map<String, Object> annotationAttributes = AnnotationUtils.getAnnotationAttributes(currentAnnotation);
                annotationAttributes.put("value", new String [] {"/method1", "/method2"});

                    AnnotationAttributes attributes = new AnnotationAttributes(annotationAttributes);
                    AnnotationUtils.postProcessAnnotationAttributes(currentAnnotation, attributes, true);

                    LOGGER.debug("GetMapping annotation after:" + currentAnnotation);
                } catch (Exception e) {
                    LOGGER.error("" + e);
                }
            }
        }
    }

QUESTION: I want to see my changes for value attribute in my current annotation.

ADDITIONAL INFORMATION: As a example for Field we can call

ReflectionUtils.setField(Field field, Object target, Object value);

and will saw our changes for that field.
