アプリで Infinispan 5.1.5 Final を使用しようとしています。以下の環境を使用しています。
- JBoss AS 7.1.1 最終版
- ハイバネート コア 4.1.5.SP1
- Hibernate Search 4.1.1 最終版
- インフィニスパン 5.1.5 ファイナル
- JBoss Seam 2.3.0 Beta2
アプリケーションの起動時に、管理者ユーザー アカウントが存在するかどうかを確認し、存在しない場合は作成します。次のように：
private void initDefaultUsersAndRoles(){
log.info("Initializing Default Roles And Passwords");
Role adminRole = roleDAO.getByName("administrator");
if (adminRole == null) {
//create new admin role
}
User admin = userDAO.findByUsername("admin ");
if (admin == null) {
//create new admin user
}
}
以下に示す userDAO.findByUsername メソッドで例外が発生します。
public User findByUsername(String username) {
User user;
try{
Query q = getEm().createQuery("SELECT e FROM "
+ entityClass.getName() + " e WHERE username = :username");
q.setParameter("username", username );
q.setHint("org.hibernate.cacheable", "true" );
user = (User) q.getSingleResult();
}
catch( NoResultException e ){
return null;
}
return user;
}
の実行時に
user = (User) q.getSingleResult()
次のエラーが表示されます。
