假設(shè)UserDao或者叫UserRepository中定義了一個(gè)函數(shù)

List<User> findByxxxx(xxx)

在Service或者Controller里，
首先注入EntityManager

@PersistenceContext 
private EntityManager entityManager;

然后調(diào)用Filter

Filter filter = entityManager.unwrap(Session.class).enableFilter("fromTime");
filter.setParameter("type", "create_content");
filter.setParameter("followerId", 1l);
List<User> list= dao.findByxxxx(xxx);
entityManager.unwrap(Session.class).disableFilter("fromTime");
return list;
