为什么不打印 666

@Report("pppp")
public class Person {

@Report(type = 1, level = "000")
public String name;

public int age;

@Report
public Person() {
}

@Report
public void run() {
}

public void skip() {
}

public void hello(@NotNull @Report2 @Report(type = 5) String name, @NotNull String prefix) {
}

}

System.out.println("_________________________________________");
Method hello = Person.class.getMethod("hello", String.class, String.class);
Annotation[][] annotation = hello.getParameterAnnotations();
for (Annotation annotation1 : annotation[0]) {
if (annotation1 instanceof NotNull) { // @NotNull注解
NotNull n = (NotNull) annotation1;
System.out.println(666);
}
if (annotation1 instanceof Report) { // @Report注解
Report r = (Report) annotation1;
System.out.println(r);
}

if (annotation1 instanceof Report2) { // @Report注解
Report2 r2 = (Report2) annotation1;
System.out.println(r2);
}
}

打印结果
