copyProperties

public static void copyProperties(Object source,
                                  Object target)
                           throws BeansException

Copy the property values of the given source bean into the target bean.

Note: The source and target classes do not have to match or even be derived from each other, as long as the properties match. Any bean properties that the source bean exposes but the target bean does not will silently be ignored.

This is just a convenience method. For more complex transfer needs, consider using a full BeanWrapper.

参数:

source - the source bean

target - the target bean

抛出:

BeansException - if the copying failed

copyProperties

public static void copyProperties(Object source,
                                  Object target,
                                  Class<?> editable)
                           throws BeansException

Copy the property values of the given source bean into the given target bean, only setting properties defined in the given "editable" class (or interface).

Note: The source and target classes do not have to match or even be derived from each other, as long as the properties match. Any bean properties that the source bean exposes but the target bean does not will silently be ignored.

This is just a convenience method. For more complex transfer needs, consider using a full BeanWrapper.

参数:

source - the source bean

target - the target bean

editable - the class (or interface) to restrict property setting to

抛出:

BeansException - if the copying failed

copyProperties

public static void copyProperties(Object source,
                                  Object target,
                                  String... ignoreProperties)
                           throws BeansException

Copy the property values of the given source bean into the given target bean, ignoring the given "ignoreProperties".

Note: The source and target classes do not have to match or even be derived from each other, as long as the properties match. Any bean properties that the source bean exposes but the target bean does not will silently be ignored.

This is just a convenience method. For more complex transfer needs, consider using a full BeanWrapper.

参数:

source - the source bean

target - the target bean

ignoreProperties - array of property names to ignore

抛出:

BeansException - if the copying failed

getPropertyDescriptors

public static PropertyDescriptor[] getPropertyDescriptors(Class<?> clazz)
                                                   throws BeansException

Retrieve the JavaBeans PropertyDescriptors of a given class.

参数:

clazz - the Class to retrieve the PropertyDescriptors for

返回:

an array of PropertyDescriptors for the given class

抛出:

BeansException - if PropertyDescriptor look fails

getPropertyDescriptor

@Nullable
public static PropertyDescriptor getPropertyDescriptor(Class<?> clazz,
                                                                  String propertyName)
                                                           throws BeansException

Retrieve the JavaBeans PropertyDescriptors for the given property.

参数:

clazz - the Class to retrieve the PropertyDescriptor for

propertyName - the name of the property

返回:

the corresponding PropertyDescriptor, or null if none

抛出:

BeansException - if PropertyDescriptor lookup fails
