Spring 3.1.1.RELEASE と Hibernate 4.1.0.Final を使用しています。関連するメソッド呼び出しを @Transactional アノテーションでラップしているにもかかわらず、「プロキシを初期化できませんでした - セッションがありません」という例外が発生します。これが私の方法です…</p>
@Service("teacherImportService")
public class TeacherImportServiceImpl extends AbstractmyprojectService
{
…
@Transactional
@Override
public void saveUserObject(final JsonObject jsonData)
{
…
final myprojectOrganization myprojectOrg = myprojectOrgDao.findBymyprojectOrgId(myprojectSchoolId);
final Organization school = myprojectOrg != null ? myprojectOrg.getOrg() : null;
…
final Address address = new Address();
address.setState(school.getState()); // error occurs here
トランザクションが行われることを保証するために他に何をしなければなりませんか? アプリケーション コンテキストに「<tx:annotation-driven />」を含めました。これを以下に含めます。
