如何在不使用AnnotationRegistry的情况下自动加载自定义注释类？

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import java.lang.reflect.Field;
import java.lang.reflect.Method;

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD, ElementType.METHOD})
@interface CustomAnnotation {
    String value();
}

class MyClass {
    @CustomAnnotation("Field Annotation")
    private String myField;

    @CustomAnnotation("Method Annotation")
    public void myMethod() {
        // Method body
    }
}

public class AnnotationLoader {
    public static void main(String[] args) {
        MyClass myObject = new MyClass();

        // 获取类的字段
        Field[] fields = myObject.getClass().getDeclaredFields();
        for (Field field : fields) {
            // 判断字段是否存在自定义注解
            if (field.isAnnotationPresent(CustomAnnotation.class)) {
                CustomAnnotation annotation = field.getAnnotation(CustomAnnotation.class);
                System.out.println("Field Annotation: " + annotation.value());
            }
        }

        // 获取类的方法
        Method[] methods = myObject.getClass().getDeclaredMethods();
        for (Method method : methods) {
            // 判断方法是否存在自定义注解
            if (method.isAnnotationPresent(CustomAnnotation.class)) {
                CustomAnnotation annotation = method.getAnnotation(CustomAnnotation.class);
                System.out.println("Method Annotation: " + annotation.value());
            }
        }
    }
}
