我正在开发一个在Tomcat上运行的Spring-MVC项目，其中我拥有用于身份验证和授权的Spring-security。由于我们的项目目前正在开发中，我们有比平常更多的部署。通常，部署之后发生的情况是所有客户端都在服务器重新启动时注销。Spring-security：即使在JVM重启后也维护活动会话
有什么办法，我可以把会话数据的数据库或其他地方，所以即使之后的Tomcat/JVM崩溃/重新启动，已登录的用户不会有问题。
有没有解决这个问题的策略？任何想法如何？
安全的applicationContext.xml：
<!-- Global Security settings -->
<security:http pattern="/resources/template/demo/clients" security="none"/>
<security:http create-session="ifRequired" use-expressions="true" auto-config="false" disable-url-rewriting="true">

LoginServiceImpl：
@Transactional
@Service("userDetailsService")
public class LoginServiceImpl implements UserDetailsService {
@Autowired
private PersonDAO personDAO;
@Autowired
private Assembler assembler;
public LoginServiceImpl() {
}
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException {
Person person = personDAO.findPersonByUsername(username.toLowerCase());
if (person == null) {
throw new UsernameNotFoundException("Wrong username or password");
}
return assembler.buildUserFromUserEntity(person);
}
}
汇编：
@Service("assembler")
public class Assembler {
@Transactional(readOnly = true)
User buildUserFromUserEntity(Person userEntity) {
String username = userEntity.getUsername().toLowerCase();
String password = userEntity.getPassword();
boolean enabled = userEntity.isEnabled();
boolean accountNonExpired = userEntity.isAccountNonExpired();
boolean credentialsNonExpired = userEntity.isCredentialsNonExpired();
boolean accountNonLocked = userEntity.isAccountNonLocked();
Collection<GrantedAuthority> authorities = new ArrayList<>();
authorities.add(new SimpleGrantedAuthority("ROLE_USER"));
return new User(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
}
}
如果有任何需要了解更多信息，请让我知道。谢谢。:-)
为什么这个问题被低估？任何解释？ –
看看这个问题和答案的想法：http://stackoverflow.com/questions/13211615/how-to-store-spring-security-session-information-in-redis – Fortunato
@Fortunato：Redis的选项执行的声音好。我已经具备了记忆功能，正如链接所言，与Redis的Spring会话已经开箱即用。任何想法，我必须改变这个项目的正确整合？ –
