Root of BeanFactory hierarchy

[wangdongzjk]

I want to use spring to manage DAOs,The spring configuration file:

<?xml version="1.0" encoding="UTF-8"?>

my test class:

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:
