maven添加**archetypeCatalog = internal**，解决maven项目速度慢的问题

另外可以修改默认设置解决maven慢的问题

## 事务 ##

### 1.更新实体 ###

private int executeCUD(T obj, String method) {
            int result = 0;
            Session session = null;
            Transaction transaction = null;
            try {
                session = getSession();
                transaction = session.getTransaction();
                transaction.begin();
                switch (method) {
                    case "C":
                        result = (int) session.save(obj);
                        break;
                    case "U":
                        session.merge(obj);
                        break;
                    case "D":
                        session.delete(obj);
                        break;
                    default:
                        break;
                }
                transaction.commit();
            } catch (Exception e) {
                if (transaction != null) {
                    transaction.rollback();
                }
                throw new RuntimeException(e.getMessage());
            } finally {
                if (session != null && session.isOpen()) {
                    session.close();
                }
            }
            return result;
        }

### 2.更新hql ###

public int executeUpdateHql(String hql, Object... params) {
            Session session = getSession();
            Transaction tx = session.beginTransaction();
            Query query = session.createQuery(hql);
            if (params != null && params.length > 0) {
                for (int i = 0; i < params.length; i++) {
                    query.setParameter(i, params[i]);
                }
            }
            int updatedEntities = query.executeUpdate();
            tx.commit();
            session.close();
            return updatedEntities;
        }

### 3.配置事务 ###

Spring的配置文件会跳过@Controller注解；而Springmvc的配置文件只会扫描@Controller。

Springmvc配置中的use-default-filters="false"是必须要有的！如果不写上，它的默认值是true，而这个default-filters会默认扫描@Service、@Repository等注解，这样就会和Spring的配置发生冲突！
