我在实现 Spring Security 以及 Spring MVC 和 Hibernate 时遇到了麻烦。
当我提供凭据并验证表单时，它会转到以下 URL： http://localhost:8080/test/login_error.htm;jsessionid=9BE14BCXXXXXXXXXXXXXXXX 所以它会将我重定向到我在我的配置中配置的 login_error.htm 页面弹簧安全.xml。看起来已经创建了一个会话，因此之后会出现问题。
我确实尝试调试以了解更多信息，这是交易：
由于在 spring-security.xml 中将 UserDetailsService 配置为我的 authenticationProvider，因此它进入了 UserDetailsServiceImpl 类中的 findByUserName 方法：
public UserDetails loadUserByUsername(String username)
throws UsernameNotFoundException, DataAccessException {
UserEntity userEntity = dao.findByName(username);
if (userEntity == null)
throw new UsernameNotFoundException("user not found");
return (UserDetails)assembler.buildUserFromUserEntity(userEntity);
}
当它返回时，用户已正确加载，因此已建立与数据库的连接并且已找到用户，那一侧没有问题。我无法弄清楚问题出在哪里。
这是我正在使用的 UserEntityDAOImpl 类：
@Repository("userEntityDao")
public class UserEntityDAOImpl implements UserEntityDAO {
private SessionFactory sessionFactory;
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public void addUser(UserEntity user) {
sessionFactory.getCurrentSession().save(user);
}
public UserEntity findByName(String username) {
Session session = sessionFactory.getCurrentSession();
UserEntity user = (UserEntity)session.createQuery("select u from UserEntity u where u.username = '" + username + "'").uniqueResult();
return user;
}
...others methods like activate, listUsers, etc...
编辑：
@Service("assembler")
public class Assembler {
@Transactional(readOnly = true)
User buildUserFromUserEntity(UserEntity userEntity) {
String username = userEntity.getUsername();
String password = userEntity.getPassword();
boolean enabled = userEntity.getActive();
boolean accountNonExpired = userEntity.getActive();
boolean credentialsNonExpired = userEntity.getActive();
boolean accountNonLocked = userEntity.getActive();
Collection<SimpleGrantedAuthority> authorities = new ArrayList<SimpleGrantedAuthority>();
for (SecurityRoleEntity role : userEntity.getSecurityRoleCollection()) {
authorities.add(new SimpleGrantedAuthority(role.getName()));
}
User user = new User(username, password, enabled,
accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
return user;
}
}
它正在从数据库中正确检索角色（在我的情况下为 ROLE_Admin）。
这是我的spring-security.xml：
