Inject Date into Spring Bean Property
July 14, 2022
Date into Spring bean property using Spring CustomDateEditor. The CustomDateEditor is a property editor for java.util.Date, supporting a custom java.text.DateFormat. It is a built-in PropertyEditor to handle Date. When we inject date to a bean in XML configuration, the value is string. With the help of CustomDateEditor, Spring converts string to date object.
Using CustomDateEditor
