@RequestMapping("/value1")

@Controller

public Class A {

   @RequestMapping("/value2")

    public String method1() {

    }

}

 

Annotation classAnnotation = A.class.getAnnotation(RequestMapping.class);

if (classAnnotation != null) {

    Class clazz = classAnnotation.annotationType();

 

    try {

        Method path = clazz.getDeclaredMethod("path");

        Method value = clazz.getDeclaredMethod("value");

 

        String[] pathArr = (String[]) path.invoke(classAnnotation);

        String[] valueArr = (String[]) value.inivoke(classAnnotation);

    } catch (Exception e) {

        e.printStackTrace();

    }

}

 

Method method1 = A.class.getMethod("method1");

Annotation method1Annotation = method1.getAnnotation(RequestMapping.class);
