在需要测试的类上右键--new-JUnitTestCase,将包改为测试包

@Test
    public void test() {
        //1.从spring容器中获取Dao
        ApplicationContext app = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        CustomerDao cd = (CustomerDao) app.getBean("customerDao");
        Customer c = cd.findById(23L);
        System.out.println("*****"+c.getCustName());
        
    }
