我創建了一個負責通過dao與數據庫聯繫的服務。我使用@Transactional註釋來處理事務。當添加全局方法安全性名稱空間時，Spring看不到@Transactional
@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;
}
@Override
@Transactional
public Acl readAclById(ObjectIdentity object) throws NotFoundException {
final Map<ObjectIdentity, Acl> objects = readAclsById(Arrays.asList(object), null);
return objects.get(object);
}
@Override
@Transactional
public Acl readAclById(ObjectIdentity object, List<Sid> sids)
throws NotFoundException {
Map<ObjectIdentity, Acl> objects = readAclsById(Arrays.asList(object), sids);
return objects.get(object);
}
@Override
@Transactional
public Map<ObjectIdentity, Acl> readAclsById(List<ObjectIdentity> objects)
throws NotFoundException {
return readAclsById(objects, null);
}
@Override
public Map<ObjectIdentity, Acl> readAclsById(List<ObjectIdentity> objects,
List<Sid> sids) throws NotFoundException {
Map<ObjectIdentity, Acl> result = new HashMap<ObjectIdentity, Acl>();
Set<Long> objectsToLoad = new HashSet<Long>();
for (int i = 0; i < objects.size(); i++) {
final ObjectIdentity oid = objects.get(i);
boolean aclFound = false;
if (result.containsKey(oid)) {
aclFound = true;
}
if (!aclFound) {
Acl acl = aclCache.getFromCache(oid);
if (acl != null) {
if (acl.isSidLoaded(sids)) {
result.put(acl.getObjectIdentity(), acl);
aclFound = true;
} else {
throw new IllegalStateException(
"Error: SID-filtered element detected when implementation does not perform SID filtering "
+ "- have you added something to the cache manually?");
}
}
}
if (!aclFound) {
objectsToLoad.add((Long) oid.getIdentifier());
}
}
if (objectsToLoad.size() > 0) {
lookupAcl(result, objectsToLoad);
}
return result;
}
public void lookupAcl(Map<ObjectIdentity, Acl> map, Set<Long> objects){
final List<AclObjectIdentity> aoids = objectIdentityDao.getList(objects);
final Map<Long, Long> parents = new HashMap<Long, Long>();
for(AclObjectIdentity aoid : aoids){
if(aoid.isEntriesInheriting()){
parents.put(aoid.getId(), aoid.getParent().getId());
}
}
if(parents.size() > 0){
lookupAcl(map, (Set<Long>)parents.values());
}
for(AclObjectIdentity aoid : aoids){
if(map.containsKey(aoid.getId()))
continue;
final Acl parentAcl = map.get(parents.get(aoid.getId()));
final Acl acl = new AclImpl(new ObjectIdentityImpl(aoid.getObjectClass().getClazz(), aoid.getId()), aoid.getId(), aclAuthorizationStrategy, grantingStrategy, parentAcl, null, aoid.isEntriesInheriting(), new PrincipalSid(aoid.getOwnerSid().getSid()));
List<AccessControlEntryImpl> aces = new ArrayList<AccessControlEntryImpl>(aoid.getAclEntries().size());
for(AclEntry aclEntry : aoid.getAclEntries()){
final Permission permission = permissionFactory.buildFromMask(aclEntry.getMask());
aces.add(new AccessControlEntryImpl(aclEntry.getId(), acl, new PrincipalSid(aclEntry.getSid().getSid()), permission, aclEntry.isGranting(), aclEntry.isAuditSuccess(), aclEntry.isAuditFailure()));
}
setAces((AclImpl) acl, aces);
aclCache.putInCache((AclImpl) acl);
}
}
private void setAces(AclImpl acl, List<AccessControlEntryImpl> aces) {
try {
fieldAces.set(acl, aces);
} catch (IllegalAccessException e) {
throw new IllegalStateException("Could not set AclImpl entries", e);
}
}
}
這裏是我的 'APP-context.xml中' 的一部分文件
<security:global-method-security pre-post-annotations="enabled">
<security:expression-handler ref="expressionHandler" />
</security:global-method-security>
<bean id="expressionHandler"
class="org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler">
<property name="permissionEvaluator" ref="permissionEvaluator" />
<property name="roleHierarchy" ref="roleHierarchy" />
</bean>
<bean class="org.springframework.security.acls.AclPermissionEvaluator"
id="permissionEvaluator">

現在，當我撥打服務的功能如。從控制器它會拋出一個錯誤org.hibernate.HibernateException: No Session found for current thread。但是，一切都（與交易沒有問題）的偉大工程時，我的評論
<security:global-method-security pre-post-annotations="enabled"> <security:expression-handler ref="expressionHandler" /> </security:global-method-security>
我檢查了一切，我縮小問題的代碼上述作品。有誰知道爲什麼會發生這種情況？
您是否已經正確配置了'？查看[文檔]（http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/transaction.html#transaction-clawial- annotations）瞭解詳細的事務管理器配置。 –
這取決於你的意思是否正確。我已經將其與默認值配置\t '
