Merge List
Spring Inversion of Control (IoC ) also known as
Dependency Injection (DI ) is a process by which
objects define their dependencies with collaborating objects.
The following example shows list merging. Spring allows us to merge
list elements defined in parent definition with child definition.
package com.bethecoder.tutorials.spring3.basic; public class ComplexBean { private java.util.Properties simpleProps; private java.util.List simpleList; private java.util.Map simpleMap; private java.util.Set simpleSet; public java.util.Properties getSimpleProps () { return simpleProps; } public void setSimpleProps ( java.util.Properties simpleProps ) { this .simpleProps = simpleProps; } public java.util.List getSimpleList () { return simpleList; } public void setSimpleList ( java.util.List simpleList ) { this .simpleList = simpleList; } public java.util.Map getSimpleMap () { return simpleMap; } public void setSimpleMap ( java.util.Map simpleMap ) { this .simpleMap = simpleMap; } public java.util.Set getSimpleSet () { return simpleSet; } public void setSimpleSet ( java.util.Set simpleSet ) { this .simpleSet = simpleSet; } }
