Bean Tutorial 1 - Hello World Bean
This Tutorial show you how to call a hello world bean using Spring IoC.
Step 1: Create a Hellobean.java in SRC
ORG / JARCHITECT / SPRING / TUTORIAL1 / HELLOBEAN.JAVA
Package org.jarchitect.spring.tutorial1; public class hellobean {public string Sayhelloworld () {return world;}}
Step 2: Specify The Hellobean Class in The Bean.xml
Bean.xml
Version = "1.0" Encoding = "UTF-8"?> beans public "- // Spring // DTD bean // en" http://www.springframework.org/dtd/spring-beans.dtd ">
Jarchitect
Spring
TUTORIAL
1
ID =
"Hellobean"
Class =
"Org.jarchitect.Spring.Tutorial1.Hellobean"
/>
Step 3: Create a main.java in SRC
ORG / JARCHITECT / SPRING / TUTORIAL1 / Main.java
package org.jarchitect.spring.tutorial1; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.InputStream; import org.springframework.beans.factory.xml.XmlBeanFactory; public class Main {public static void main (String [] args) {try {// Read the configuration file InputStream is = new FileInputStream ( "bean.xml"); XmlBeanFactory factory = new XmlBeanFactory (is); // Instantiate an object helloBean helloBean = (helloBean) factory .getBean ("Hellobean"); // Execute the public method of the hellobean system.out.println (hellobean.sayhelloworld ());} catch (filenotfoundexcection e) {E.PrintStackTrace ();}}}
Step 4: Use an ant script to build and execute the main class. Just Run Ant from The Command Prompt Will Do The Trick.
BELOW is The Output from Ant.
