测试代码

@Test()
    public void testTransaction3(){
        ApplicationContext context =new AnnotationConfigApplicationContext(SpringConfig.class);
        AccountService accountService = context.getBean(AccountService.class);
        int rows = accountService.transMoney(1, 2, 100);
        System.out.println(rows);
    }
