-------------------------------------

             Summary: Add a New Method, `copyNonNullProperties`, to the 
BeanUtils Library
                 Key: BEANUTILS-573
                 URL: https://issues.apache.org/jira/browse/BEANUTILS-573
             Project: Commons BeanUtils
          Issue Type: New Feature
          Components: Bean / Property Utils
    Affects Versions: 1.9.4, 2.0.0
            Reporter: dawei xiong
             Fix For: 2.0.0, 1.9.4


When we input an incomplete object (i.e., an object where not all properties 
are assigned values, or said some properties are null) and need to copy its 
properties to another object, we do not always want to overwrite the target 
object's corresponding properties with null values from the input. This feature 
will prevent null values from overwriting existing values in the target object, 
ensuring that only the provided properties are updated.
