lombok插件

@RequiredArgsConstructor(onConstructor_ = @Autowired)
public class V3CauseCustomDaoImpl implements V3CauseCustomDao {

private final BiDao biDao;
private final EntityManager entityManagerCaseCause; 
}

代替
@Autowired
private EntityManager entityManager;

@Autowired

private BiDao biDao;

可省略很多次的@Autowired代码
