Method Detail

mergeProperties

public static void mergeProperties(Object source,
                                   Object target)
                            throws org.springframework.beans.BeansException

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

Note: Only not-null values are merged into the given 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.

Parameters:

source - the source bean

target - the target bean

Throws:

org.springframework.beans.BeansException - if the copying failed

mergeProperties

public static void mergeProperties(Object source,
                                   Object target,
                                   Class<?> editable)
                            throws org.springframework.beans.BeansException

Merge 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: Only not-null values are merged into the given 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.

Parameters:

source - the source bean

target - the target bean

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

Throws:

org.springframework.beans.BeansException - if the copying failed

mergeProperties

private static void mergeProperties(Object source,
                                    Object target,
                                    Class<?> editable,
                                    String[] ignoreProperties)
                             throws org.springframework.beans.BeansException

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

Note: Only not-null values are merged into the given 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.

Parameters:

source - the source bean

target - the target bean

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

ignoreProperties - array of property names to ignore

Throws:

org.springframework.beans.BeansException - if the copying failed

Find all occurrences of targetClass in targetObject. Be careful. This stuff may be recursive ! Should be improved to prevent endless recursive loops.

Parameters:

targetObject -

targetClass -

nestedPath -

Returns:

Throws:

Exception
