小编use*_*146的帖子

我创建了一个负责通过dao与数据库联系的服务.我使用@Transactional注释来处理事务.

@Service("aclService")
public class HibernateAclServiceImpl implements HibernateAclService{

private final Log logger = LogFactory.getLog(HibernateAclServiceImpl.class);
@Autowired
private AclObjectIdentityDao objectIdentityDao ;
private PermissionFactory permissionFactory = new DefaultPermissionFactory();
@Autowired
private AclCache aclCache;
@Autowired
private PermissionGrantingStrategy grantingStrategy;
@Autowired
private AclAuthorizationStrategy aclAuthorizationStrategy;

private final Field fieldAces = FieldUtils.getField(AclImpl.class, "aces");

@Override
@Transactional
public List<ObjectIdentity> findChildren(ObjectIdentity parentIdentity) {
    AclObjectIdentity aclObjectIdentity = objectIdentityDao
            .get((Long) parentIdentity.getIdentifier());
    List<ObjectIdentity> list = new ArrayList<ObjectIdentity>(
            aclObjectIdentity.getChildren().size());
    for (AclObjectIdentity aoid : aclObjectIdentity.getChildren()) {
        final ObjectIdentity oid = new ObjectIdentityImpl(aoid.getObjectClass().getClazz());
        list.add(oid);
    }
    return list; …
