ant+Junit的单元测试无法启动spring容器

Question

以下junit的单元测试启动了Spring容器，在eclipse运行正常

@Test
	public void add(){
        System.out.println("Spring begin");
		ApplicationContext ac = new ClassPathXmlApplicationContext(
        "applicationContext.xml");
		final ISpiderService jdtuhu = (ISpiderService) ac.getBean("JdTuhuService");
		System.out.println(jdtuhu.toString());
		jdtuhu.work();
	}

但是用Ant 脚本调用junit时无法加载spring容器，有遇到同样问题的吗？
