Typed List Injection
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 typed list injection.
package com.bethecoder.tutorials.spring3.basic; public class ComplexTypedBean { private java.util.Properties simpleProps; private java.util.List<Double> simpleList; private java.util.Map<String, Float> simpleMap; private java.util.Set<Long> simpleSet; public java.util.Properties getSimpleProps () { return simpleProps; } public void setSimpleProps ( java.util.Properties simpleProps ) { this .simpleProps = simpleProps; } public java.util.List<Double> getSimpleList () { return simpleList; } public void setSimpleList ( java.util.List<Double> simpleList ) { this .simpleList = simpleList; } public java.util.Map<String, Float> getSimpleMap () { return simpleMap; } public void setSimpleMap ( java.util.Map<String, Float> simpleMap ) { this .simpleMap = simpleMap; } public java.util.Set<Long> getSimpleSet () { return simpleSet; } public void setSimpleSet ( java.util.Set<Long> simpleSet ) { this .simpleSet = simpleSet; } }
package com.bethecoder.tutorials.spring3.tests.typed_collections; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.ClassPathResource; import com.bethecoder.tutorials.spring3.basic.ComplexTypedBean; public class TypedListInjection { /** * @param args */ public static void main ( String [] args ) { XmlBeanFactory factory = new XmlBeanFactory ( new ClassPathResource ( "typed_list_inj.xml" )) ; ComplexTypedBean complexBean = ( ComplexTypedBean ) factory.getBean ( "complexBean" ) ; System.out.println ( complexBean.getSimpleList ()) ; } }
