public class AppTest {
@Test
public void beanTest(){
ClassPathXmlApplicationContext context = new
ClassPathXmlApplicationContext("applicationContext.xml");
ICustomerService customerService = (ICustomerService)
context.getBean("customerServiceImpl");
customerService.save(new Customer());
context.destroy();
}
}19.在测试类AppTest的beanTest方法上右键运行,输出结果如图所示
