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:

please help me!

You have a simple typo. The parent values should actually be "txProxyTemplate", like the parent definition.

The error message is completely correct. Note that it shows a list of defined beans, that includes the correctly spelled version of the parent bean.

thank you for your help!
but i have a new problem:
my daos can not rollback when one of them insert failure.
Is spring can manage daos on service layer?

[wangdongzjk]

my table struct:

create table menu(
  id bigint not null auto_increment,
  parentid bigint not null,
  menuname varchar(50) unique,
  menulink varchar(100),
  primary key(id)
)type=innodb;

my dao method:

public boolean saveMenu(Menu menu) {
    try{
      [b]getHibernateTemplate().save(menu);[/b]
      return true;
    }
    catch {
      return false;
    }
  }

but method getHibernateTemplate().save() can't capture insert exception?
why?
