Java EE、Spring、EclipseLink、および Glassfish サーバーを使用して Web アプリケーションに取り組んでいます。
私のアプリケーションは、Spring でエンティティマネージャーを注入し、より良いトランザクション管理を有効にするために、Bean 構成を変更しようとする前に問題なく動作していました...動作しません... (その前に、すべての各データベース要求の前に emf.createEntityManager() を呼び出す必要があることを除いて、同じです)。
ここに私の設定ファイルがあります:

persistence-config と security-config のインポートについてはよくわかりません...
すべての情報が揃っていることを確認するために、entitymanager を注入するクラス MyDAOFactory を次に示します。
/**
* A factory for creating DAO objects.
*/
@Component
public class MyDAOFactory implements IMyDAOFactory{
/** The map dao. */
private Map<Class<?>, IDao<?>> mapDAO;
/** The entity manager. */
@PersistenceContext(unitName="databaseName")
public EntityManager em;
/**
* Instantiates a new my dao factory.
*/
public MyDAOFactory() {
mapDAO = new HashMap<Class<?>, IDao<?>>();
}
/**
* Gets the em.
*
* @return the em
*/
public EntityManager getEm() {
return em;
}
/**
* Sets the em.
*
* @param emf the new em
*/
public void setEm(EntityManager em) {
this.em = em;
}
@Override
public <T extends Serializable> IDao<T> getBasicDAO(Class<T> entity) {
if(mapDAO.containsKey(entity)){
return (IDao<T>) mapDAO.get(entity);
}else{
BasicDAO<T> dao = new BasicDAO<T>(entity);
dao.setEm(em);
mapDAO.put(entity, dao);
return dao;
}
}
}
そして、カスタム UserDetailsService:
@Transactional
public class MyUserDetailsService implements UserDetailsService {
/** The my dao factory. */
IMyDAOFactory myDAOFactory;
/**
* Instantiates a new means user details service.
*
*/
public MyUserDetailsService(IMyDAOFactory myDAOFactory) {
this.myDAOFactory = myDAOFactory;
}
/* (non-Javadoc)
* @see org.springframework.security.core.userdetails.UserDetailsService#loadUserByUsername(java.lang.String)
*/
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException{
IDao<Utilisateur> userDAO = this.myDAOFactory.getBasicDAO(Utilisateur.class);
Map<String, String> map = new HashMap<String, String>();
map.put("loginLdap", username);
Utilisateur user = userDAO.findByAttributes(map).get(0);
IMyUserDetails userDetails = new MyUserDetails(user.getLoginLdap(), user.getPwdLocal(), user.getActif(), user.getDateValidite().getTime()>System.currentTimeMillis(), true, true, AuthorityUtils.createAuthorityList("ROLE_"+user.getProfil().getNomProfil().toUpperCase()));
userDetails.setUser(user);
return userDetails;
}
}
デバッグ モードでサーバーを起動すると、myDAOFactory が MyUserDetailsService に挿入されたときにエンティティ マネージャーがセットアップされたようですが、アプリにログインしようとすると、どういうわけか loadUserByName の呼び出しが行われなくなりました... (ただし、構成のこの部分は変更しませんでした...)。
どんな助けでも大歓迎です！
