写完我自己已经吐了
@Service
public class PubManager<T, PK extends Serializable>{
private SessionFactory sessionFactory;
@Autowired
private PubManagerImpl<T, PK> mgr;
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public PubManagerImpl<T, PK> getI(Class<T> c){
if(null == mgr.getDAO()){
mgr.setDao(new HibernateDao<T, PK>(sessionFactory ,c));
}
return mgr;
}
}
@Service
@Transactional
public class PubManagerImpl<T, PK extends Serializable> extends AbsManager<T, PK> implements absMgr<T, PK> {
private HibernateDao<T, PK> dao;
@Override
public HibernateDao<T, PK> getDAO() {
return dao;
}
public void setDao(HibernateDao<T, PK> dao) {
this.dao = dao;
}
}
@Controller
@RequestMapping("/xxx/xxxx")
public class XxxxXxxxXxxController {
@Autowired
private CodeManager codeManager;
@Autowired
private PubManager<XxxxxXxxxXxxx, String> pubManager;
@RequestMapping("allXxx")
public @ResponseBody Page<XxxxxXxxxXxxx> logs(){
return pubManager.getI(XxxxxXxxxXxxx.class).searchByPage();
}
}
需要获得运行时的Class<T> 感觉上是可以做到样子…… 参照泛型DAO的写法 完全不行 人家也不是万用实现 求打通七筋八脉~ 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。

PubManager有错误，不同的泛型居然是单例的，没想到
@Service
public class PubManager<T, PK extends Serializable>{
private SessionFactory sessionFactory;
private PubManagerImpl<T, PK> mgr;
private Map<Class<T>, HibernateDao<T, PK>> daoMap = new HashMap<Class<T>, HibernateDao<T, PK>>();
@Autowired
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@Autowired
public void setPubManagerImpl(PubManagerImpl<T, PK> mgr) {
this.mgr = mgr;
}
public PubManagerImpl<T, PK> getI(Class<T> c){
if(!daoMap.containsKey(c))
daoMap.put(c, new HibernateDao<T, PK>(sessionFactory ,c));
mgr.setDao(daoMap.get(c));
return mgr;
}
}
