java反射高级用列（脱敏+aop）

ClassUtils 、FieldUtils、MethodUtils、ReflectionUtils高级

List<String> list = new ArrayList<>();
Class<?> userClass = ClassUtils.getUserClass(list.getClass());
System.out.println(Collection.class.isAssignableFrom(userClass));
Class<?> clazz = Class.forName("com.sd.entity.User");
Object instance = clazz.getDeclaredConstructor().newInstance();
BeanUtils.populate(clazz, map);
instanceofReflectionUtils.doWithFields(MyClass.class, field -> {// 对每个字段执行操作
});ReflectionUtils.doWithMethods(MyClass.class, method -> {// 对每个方法执行操作
});ReflectionUtils.doWithFields(MyClass.class, field -> {// 对每个带有特定注解的字段执行操作
}, field -> field.isAnnotationPresent(MyAnnotation.class));ReflectionUtils.doWithMethods(MyClass.class, method -> {// 对每个带有特定注解的方法执行操作
}, method -> method.isAnnotationPresent(MyAnnotation.class));//获取类的所有带有特定注解的字段
List<Field> fields = FieldUtils.getFieldsListWithAnnotation(MyClass.class, MyAnnotation.class);//获取字段值
Field field = ReflectionUtils.findField(MyClass.class, "myField");
Object fieldValue = ReflectionUtils.getField(field, myClassInstance);//读取字段值（忽略访问修饰符）
Object fieldValue = FieldUtils.readField(field, myClassInstance, true);//readStaticField读取静态值//设置字段值
Field field = ReflectionUtils.findField(MyClass.class, "myField");//字段名称
ReflectionUtils.setField(field, myClassInstance, "newValue");
FieldUtils.writeField(field, myClassInstance, "newValue", true);
