我正在使用 Java EE、Spring、EclipseLink 和 Glassfish 服务器开发一个 Web 应用程序。
在我尝试更改我的 bean 配置以便用 Spring 注入 entitymanager 并启用更好的事务管理之前，我的应用程序工作得很好......我没有让它工作......（在此之前我拥有所有一样，除了我必须在每个数据库请求之前调用 emf.createEntityManager() ）。
这是我的配置文件：

我不确定持久性配置和安全配置的导入...
为确保您掌握了所有信息，这里是注入实体管理器的 MyDAOFactory 类：
/**
* 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;
}
}
}
以及自定义的 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;
}
}
当我以调试模式启动服务器时，似乎在将 myDAOFactory 注入 MyUserDetailsService 时设置了实体管理器，但是当我尝试登录我的应用程序时，对 loadUserByName 的调用不再发生......（虽然我没有更改这部分配置...）。
任何帮助都将不胜感激！
