springframework.beans.BeanUtils

BeanUtils is a class in the Spring Framework that provides utility methods for manipulating JavaBeans. These methods can be used to copy properties from one bean to another, to create new instances of beans, and to populate beans with data from other sources. Some of the methods in this class include:

- copyProperties(Object source, Object target): Copies the properties from the source bean to the target bean.
- copyProperties(Object source, Object target, String... ignoreProperties): Copies the properties from the source bean to the target bean, ignoring any properties listed in the ignoreProperties array.
- instantiate(Class<T> clazz): Creates a new instance of the specified class.
- populate(Object bean, Map<?, ?> properties): Populates the properties of the bean with the values from the properties map.

In addition to these methods, BeanUtils also provides several other utility methods for working with JavaBeans. These methods can help simplify the process of working with beans and make it easier to write maintainable, reusable code.
