spring data实现自定义的repository实现类，实现跟jpa联通

    @PersistenceContext  
    private EntityManager em;     
    public Page<Object[]> getByCondition(UserQueryModel u){  
String hql = "select o.uuid,o.name from UserModel o where 1=1 and o.uuid=:uuid";  
        Query q = em.createQuery(hql);  
        q.setParameter("uuid", u.getUuid());          
        q.setFirstResult(0);  
        q.setMaxResults(1);       
Page<Object[]> page = new PageImpl<Object[]>(q.getResultList(),new PageRequest(0,1),3);   
        return page;  
}}
