Root of BeanFactory hierarchy
I want to use spring to manage DAOs,The spring configuration file:
Code:
<?xml version="1.0" encoding="UTF-8"?>

</beans>
my test class:
Code:
package test.sales.service.impl;
import junit.framework.*;
import com.sales.service.*;
import com.sales.service.impl.*;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.beans.factory.BeanFactory;
public class _TestMenuManagerImpl
extends TestCase {
private MenuManager menuService = null;
private ApplicationContext ctx = null;
private BeanFactory app;
protected void setUp() throws Exception {
super.setUp();
String[] paths = {
"/ApplicationContext-hibernate.xml", "/ApplicationContext-service.xml"};
ctx = new ClassPathXmlApplicationContext(paths);
app = (BeanFactory)ctx;
menuService = (MenuManager)app.getBean("menuManager");
}
protected void tearDown() throws Exception {
menuService = null;
super.tearDown();
}
public void testSaveMenu() {
long parentid = 0;
String menuName = "menu2";
String menuLink = "http://localhost:8080";
boolean flag = menuService.saveMenu(parentid, menuName,
menuLink);
if(flag)
System.out.println("save success");
else
System.out.println("save failure");
}
}
Running this demo will output to the console profing the expected result:
Code:
