?? ?2.在test目錄下創(chuàng)建測(cè)試包
?? ??? ?包名：cn.jbit.spring101310.service
?? ?3.在測(cè)試包下創(chuàng)建測(cè)試類
?? ??? ?測(cè)試類名：AccountServiceTest.java

?? ??? ?public class AccountServiceTest {
?? ??? ??? ?@Test
?? ??? ??? ?public void testTranser(){
?? ??? ??? ??? ?ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");

?? ??? ??? ??? ?Account outAccount = new Account();
?? ??? ??? ??? ?outAccount.setId(1);
?? ??? ??? ??? ?outAccount.setMoney(500D);
?? ??? ??? ??? ?Account inAccount = new Account();
