	@Test
	public void addressMapperTest() throws IOException{
		//能够手动载入
		//PropertyConfigurator.configure(UserMapperTest.class.getClassLoader().getResource("log4j.properties"));

		AddressMapper addressMapper=(AddressMapper)BeanFactoryUtil.getInstance().getBean("addressMapper");
		Address address=addressMapper.getAddressByAid(4);
		System.err.println("address======="+address.getAddress());
