BeanUtils.copyProperties(vechicleInfo, vechicleInfoRes);

`BeanUtils.copyProperties()` 是 Apache Commons BeanUtils 库中的一个方法，用于将一个 Java Bean 对象的属性值复制到另一个 Java Bean 对象中相应的属性。该方法的语法为：

public static void copyProperties(Object dest, Object orig)

其中，`dest` 是目标对象，`orig` 是源对象。该方法会将 `orig` 对象的属性值复制到 `dest` 对象中相应的属性。

这个方法内部使用了 Java 的反射机制，通过获取源对象和目标对象的属性列表，然后逐个对应复制属性值。该方法会自动进行类型转换和属性拷贝，不需要手动处理。

使用该方法需要导入 Apache Commons BeanUtils 库，并在代码中使用 `import org.apache.commons.beanutils.BeanUtils;` 来引入该类。

请注意，`BeanUtils.copyProperties()` 方法的属性复制是按照属性名称进行的，如果属性名称不匹配或类型不兼容，可能会导致属性值复制失败。

BeanUtils.copyProperties

BeanUtils.copyProperties is a method in the Apache Commons BeanUtils library that allows for the copying of properties from one JavaBean object to another. This method is commonly used in Java applications to transfer data between objects, or to create a new object with the same properties as another object.

The method takes two parameters: the source object and the destination object. The source object is the object from which the properties will be copied, and the destination object is the object to which the properties will be copied. The method copies all properties with the same name and type from the source object to the destination object.

BeanUtils.copyProperties is a convenient way to copy properties between JavaBean objects without having to write custom code. However, it is important to note that this method only copies properties that have a getter and a setter method in both the source and destination objects. If a property does not have a corresponding getter or setter method, it will not be copied. Additionally, the method does not handle complex types, such as collections or nested objects, by default.

Overall, BeanUtils.copyProperties is a useful method for quickly copying properties between JavaBean objects in a Java application.
