Spring + eclipselink事务回滚无法正常工作

Question

在我的服务类中，当抛出异常时，回滚不起作用，出了什么问题？

UserTest类

 @Test
public void checkCreatingAdminUser() throws AppException {

    String name = "Admin 1";
    String username = "admin1";
    String password = "Adminuser1";

    Assert.assertTrue(AppUtils.matchesPasswordMask(password));

    Boolean active = true;
    String email = "admin1@ad.ru";

    try {
        Assert.assertNull(userService.findByUsername(username));

        User user = userService.createAdminUser(name, username, password, active, email);


    } catch (Exception e) {
        // TEST FAILES HERE!
        Assert.assertNull(userService.findByUsername(username));
    }
}

UserService类

public interface UserService {


        User createAdminUser(String name, String username, String password, Boolean active, String email) throws AppException;

        User findByUsername(String username);
    }   

实施服务类

 @Override
public User createAdminUser(String name, String username, String password, Boolean active, String email) throws AppException {
    if (findByUsername(username) != null) {
        throw new AppException(AppError.USER_EXISTS_BY_USERNAME);
    }

    try {
        return createAdminUserTr(name, username, password, active, email);
    } catch (Exception e) {
        logger.error("Error on create admin group", e);
        throw new AppException(AppError.DB_INTERNAL_ERROR);
    }
}

 @Transactional
public User createAdminUserTr(String name, String username, String password, Boolean active, String email) {
    User user = new User();
    user.setName(name);
    user.setUsername(username);
    user.setPassword(hashPassword(password));
    user.setActive(active);
    user.setEmail(email);
    user.setCreateDate(new Date());

    userRepository.save(user);

    throw new RuntimeException("check rollback test");

}

我认为问题出在我的配置中，但我没有找到它
