    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations={"classpath:/applicationContext.xml"})
    public class TestUserService {

    @Autowired
    private UserService userService;
    @Test
    public void hasMatchUser() {
        boolean b1=userService.hasMatchUser("admin", "123456");
        boolean b2=userService.hasMatchUser("admin", "11111");
        assertTrue(b1);
        assertTrue(!b2);
    }

    @Test
    public void findUserByName(){
        User user = userService.findUserByUserName("admin");
        assertEquals(user.getUserName(),"admin");
    }
}

我不知道怎么解决这个问题，谁能帮我？多谢！

看来您必须更改org.apache.commons.dbcp.basicDataSource的jar文件。这会产生问题

UnsupportedClassVersionError: Bad version number in .class file Related cause:
