Java 根据方法路径获取方法上面注解

public static void main(String[] args) throws Exception {
        // 方法路径
        String methodPath = "x.x.x.x.methodA";
        // 类加载 方法类
        Class<?> clazz = Class.forName(methodPath.substring(0, methodPath.lastIndexOf(".")));
        // 获取该类所有的方法
        Method[] methods = clazz.getDeclaredMethods();
        for (Method method : methods) {
            //所有方法上的注解
            Annotation[] declaredAnnotations = method.getDeclaredAnnotations();
            //获取指定注解
            DataPermission annotation = method.getAnnotation(DataPermission.class);
            System.out.println(Arrays.toString(declaredAnnotations) + ":" + method.getName() + ":" + annotation + ":");
        }
    }
