春季启动登录应用程序：用户名或密码错误

Question

我是Spring Boot的新手。尝试与其余服务集成并休眠，然后使用正确的凭据登录，以获取“无效的密码或用户名”

@Configuration
public class AppConfig {
@Bean
public userDao userRepository() {
    System.out.println("repo from bean");
    return new userDaoImpl();
}

@Bean
public userService userService() {
    System.out.println("ser from bean");
    return new userServiceImpl();
}

@SuppressWarnings("deprecation")
@Bean
public HibernateJpaSessionFactoryBean sessionFactory(){
    System.out.println("seesion factory from bean");
    return new HibernateJpaSessionFactoryBean();
}}
@Service
public class userServiceImpl implements userService {
    @Autowired
    private userDao userDao;

    public void setUserDao(userDao userDao) {
        this.userDao = userDao;
    }

    @Transactional
    public Users validateUser(String Username, String password) {
        return userDao.validateUser(Username, password);
    }}

@Repository
    public class userDaoImpl extends SpringBeanAutowiringSupport implements userDao {

    private static final Logger logger = LoggerFactory.getLogger(userDaoImpl.class);
    @Autowired
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

      public Users validateUser(String Username, String password) {

         Criteria criteria = this.sessionFactory.getCurrentSession().createCriteria(Users.class);
        if (!StringUtils.isEmpty(Username)) {
            criteria.add(Restrictions.eq("username", Username));
        }
        if (!StringUtils.isEmpty(password)) {
            criteria.add(Restrictions.eq("password", password));
        }
        @SuppressWarnings("unchecked")
        List<Users> users = (List<Users>) criteria.list();
        if (!users.isEmpty()) {
            return users.get(0);
        }
        return null;
     }}

当我从邮递员（http://localhost:8080/loginProcess?username=abc&password=xyz）呼叫我的休息服务时，其中abc和xyz是用户的有效凭据，将显示“嗨abc”和“用户名或密码错误！”。

Answer 1

在application.properties文件中，定义了db连接规范，例如db.driver，用户名，pwd等。在appConfig.java中为数据源创建bean，例如

 @Bean
 public DataSource dataSource() {
 DriverManagerDataSource dataSource = new DriverManagerDataSource();
 //set values for datasource -username, pwd, driverclass etc.}
