我有一個非常奇怪的異常被拋出，這是非常令人沮喪的跟蹤。當我從休眠狀態切換到Eclipselink時，這種行爲開始，以滿足對缺少功能的需求。RollbackException與Spring Web Flow 2.2 +/Spring 3.05和EclipseLink 2.1.2
這似乎是Spring和Eclipselink之間對我的一種溝通小姐，但它也可能是我的配置錯失。你能幫我弄清楚這一點嗎？我把我的頭髮拉過來可能很簡單。
任何幫助將不勝感激！

這裏是有問題的方法：
@Override
@Transactional(readOnly = true)
public List<entityType> listAll() {
String entityName = entityClass.getSimpleName();
if (entityClass.isAnnotationPresent(Entity.class)) {
Entity ea = (Entity) entityClass.getAnnotation(Entity.class);
if (ea.name() != null && ea.name().length() > 0) {
entityName = ea.name();
}
// TODO: If this query exists: entityName + ".list", use it, otherwise:
EntityManager em = getEntityManager();
Query query = null;
try {
// Try and find a query with the name (EntityName).list
query = em.createNamedQuery(entityName + ".list");
} catch (IllegalArgumentException ex) {
try {
// No query with this name, so fill it in with a custom query
if (entityClass.getMethod("deletedDate", Date.class) != null) {
query = em.createQuery("SELECT e FROM " + entityName + " e WHERE deletedDate is null");
} else {
throw new NoSuchMethodException();
}
} catch (NoSuchMethodException ex1) {
query = em.createQuery("SELECT e FROM " + entityName + " e");
}
}
return query.getResultList();
}
return null;
}

工作這是我能拿出來測試在運行時命名查詢的存在，最快捷的方式。回想起來，我確實有一個持久化實體的列表，並且可以像JPA那樣掃描它們以查找類似的@NamedQueries註釋，但是這讓我覺得應該有更好的方法來做到這一點。現在測試這個解決方案。 – SplinterReality 2011-03-02 05:37:24
不知何故，只是做noRollbackFor，無論是在XML配置，還是在@Transactional，都沒有工作。然而，感謝你的指針，我藉此機會重新設計了listAll（）函數來被動地使用預先計算的列表查詢，這是在Dao實例化時計算出來的。這似乎解決了這個問題。 – SplinterReality 2011-03-02 06:15:20
