How to pass parameter(s) via constructor to another object dynamically with spring annotation

Let say we have a simple class like below. We could use it within/without default constructor. I am really curious about is it possible to pass argument/parameter to another object via constructor in Spring framework. To explain what I want to do, please see the code sample below.

public class Class{
    String text = null;
    String text2 = null;

    Class( text, text2 ){
        this.text = text;
        this.text2 = text2;

    public void toString(){
        System.out.printf( "Text" + text + ", " + "Text2" + text2);

    /** Methods and Setter/Getter etc. **/


After defining class and Spring annotations, I would like to call this object via Spring.

public class Usage{
    Class classExample;

    public void method(){
        String text = "text";
        String text2 = "text2";

        /** One way can be using setters **/
        System.out.println( classExample.toString() );

        /** Another way can be using a method **/
        classExample.set(text, text2);
        System.out.println( classExample.toString() );

        /**What I wanted is calling it via constructor injection dynamically**/

        /** Normal way we could call this **/
        //classExample = new Class(text, text2);
        //System.out.println( classExample.toString() );


Is it possible to inject parameter(s) dynamically to another object.


If you use spring xml configuration you can use the constructor-arg parameter.

<bean id="exampleBean" class="examples.ExampleBean">
   <constructor-arg type="int" value="7500000"/>
   <constructor-arg type="java.lang.String" value="42"/>

But remember, the default scope of your bean is singleton!

Is it possible to inject parameter(s) dynamically to another object.

Lets create a "dynamic" bean, so lets set the scope of the bean to prototype to get a fresh instance evrytime it gets called.

<bean id="exampleBean" class="examples.ExampleBean" scope="prototype">
   <constructor-arg type="int" value="#{getRandomNumber}"/>

In this case, every time a new bean will be created with a new random number.

You should take a look at FactoryBean

Page_Load(object sender, EventArgs e)---Why is "object" not capitalised?

c# .net

"object" here should refer to the "Object" class. As with all class identifiers in the .NET framework, it is supposed to be capitalised although not case sensitive. But I realise in c# it is not
