我想從「漂亮」的人類可讀的URL到webcenter內部表示的URL重寫，反之亦然。我使用AssetDataManager將資產ID映射到資源描述，我在URL中使用，反之亦然。這就是我與URL組件：與oracle webcenter網站的Url重寫會話問題11gR1
Session ses = SessionFactory.getSession();
AssetDataManager mgr = (AssetDataManager) ses
.getManager(AssetDataManager.class.getName());
List<AssetId> assets = new ArrayList<AssetId>();
assets.add(new AssetId()
{
private long id = assetId;
private String type = "Page";
@Override
public String getType()
{
return type;
}
@Override
public long getId()
{
return id;
}
});
Iterable<AssetData> assetDataItems = mgr.read(assets);
這是URL拆解：
Session ses = SessionFactory.getSession();
AssetDataManager mgr = (AssetDataManager) ses
.getManager(AssetDataManager.class.getName());
final String assetType = "Page";
final String subType = null;
final Condition condition = ConditionFactory.createCondition(
"description", OpTypeEnum.EQUALS, pageName);
final List<String> desiredAttributes = Arrays.asList("id");
Query query = new SimpleQuery(assetType, subType, condition,
desiredAttributes);
query.getProperties().setIsBasicSearch(true);
Iterable<AssetData> assetDataItems = mgr.read(query);
兩者都在我的自定義彙編程序的情況下，延伸QueryAssembler使用。 大會工作正常，重用現有會話，但拆卸失敗：

這似乎很奇怪。由於某些原因，它無法使用現有會話。如果我改變拆卸會議檢索到這一點，它工作正常：
Session ses = SessionFactory.newSession(userName, pass);
不過，我肯定不會想我要解決的網址，每次創建另一個會話。爲什麼我會得到異常？什麼是處理這個問題的好方法？
