Spring无法为当前线程获取事务同步的Session

Question

我正在尝试在我的spring应用程序中测试更改密码功能，但我有一个例外。

我在这里读过类似的问题并尝试使用它们，但它们并没有帮助我。当我想运行测试类来测试用于更改密码的方法是否正常工作时，会出现此问题。这是我的测试类：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = UiApplication.class)
@WebAppConfiguration
public class SecurityServiceTest {

    @Autowired
    SecurityService securityService;

    @Test
    public void testLoginSuccess() {
        securityService.login("user1", "pass1");
    }

    @Test(expected = BadCredentialsException.class)
    public void testLoginFail() {
        securityService.login("user1", "pass11");
    }
    @Test
    public void testChangePwd(){

        securityService.changePwd("user1", "pass1", "123", "123");
        securityService.login("user1", "123");
    }
}

我添加最后一个测试testChangePwd()后发生问题，然后再添加它才能正常工作。

UPDATE- SecurityService是一个接口，它的实现是以下类：

@Service
public class SecurityServiceImpl implements SecurityService {

    private static Logger logger = Logger.getLogger(SecurityServiceImpl.class);
    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private UserDetailsService userDetailsService;
    @Autowired
    private UserDaoImpl userDao;
    @Override
    public void login(String username, String password) {

        UserDetails userDetails = userDetailsService.loadUserByUsername(username);
        UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(userDetails, password, userDetails.getAuthorities());

        authenticationManager.authenticate(usernamePasswordAuthenticationToken);

        if (usernamePasswordAuthenticationToken.isAuthenticated()) {
            SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
            logger.info(String.format("Auto login %s successfully!", username));
        }
    }

    @Override
    public void changePwd(String username, String password, String newPwd, String againPwd) {
         UserDetails userDetails = userDetailsService.loadUserByUsername(username);
            UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(userDetails, password, userDetails.getAuthorities());

            authenticationManager.authenticate(usernamePasswordAuthenticationToken);

            if (usernamePasswordAuthenticationToken.isAuthenticated()) {
                if(newPwd.equals(againPwd))
                userDao.findByUserName(username).setPassword(password);
            }

    }

}

以下是例外：
