Java休眠过滤器无法正常工作

我尝试使用Hibernate过滤器获取User实体与子女（Filter->Ad）实体通过insertTime条件。我的目标是获取带有insertTime>（现在为7天）的广告的用户对象。在测试模式下，我使用内存中的HSQLDB。Java休眠过滤器无法正常工作

但测试不是绿色：

getNotOldAds(com.gecars.app.dao.DaoTester) java.lang.AssertionError: expected:<1> but was:<2> ...

测试：

@Before 
public void before() throws ParseException { 
    sessionFactory = HibernateUtilTest.getSessionFactory(); 
    session = sessionFactory.openSession(); 

    dao = new DAOimpl(session); 

    GeUser user = new GeUser(); 
    user.setId(1); 
    Filter filter = new Filter(); 

    Ad ad = new Ad(); 
    Ad old = new Ad(); 

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); 
    Date insertTime = sdf.parse("2015-01-01"); 

    old.setInsertTime(insertTime); 

    filter.addAd(ad); 
    filter.addAd(old); // should filter this old ad !!! 

    user.addFilter(filter); 

    dao.insertUser(user); 
} 

@Test 
public void getNotOldAds() throws Exception{   
    GeUser u = dao.getUser(1); 
    assertEquals(1, u.getFilters().size()); 
    assertEquals(1, u.getFilters().get(0).getAds().size()); // red test !!! 
}

用户：

@Entity 
@Table(name="users") 
public class GeUser { 
    ... 
    @OneToMany(fetch = FetchType.LAZY, cascade=CascadeType.ALL, mappedBy="user") 
    @OrderBy("id") 
    private Set<Filter> filters = new HashSet<Filter>(0); 

    public void addFilter(Filter filter){ 
     this.filters.add(filter); 
    } 
    ...

筛选：

@Entity 
@Table(name="filters") 
@FilterDef(name="time", parameters={ 
    @ParamDef(name="adTime", type="date") 
}) 
public class Filter { 
    ... 
    @ManyToMany(cascade=CascadeType.ALL) 
    @FilterJoinTable(name="time", condition=":adTime >= insertTime") 
    private Set<Ad> ads; 
    ...

也试过@Filter注释：

@Entity 
@Table(name="ads") 
public class Ad { 
    ... 
    private Date insertTime = new Date(); // > no less 7 days 
    ...

负载用户使用的DAO方法：

@Table(name="filters") 
@FilterDef(name="time", parameters={ 
    @ParamDef(name="adTime", type="date") 
}) 
public class Filter { 
     ... 
     @ManyToMany(cascade=CascadeType.ALL) 
     @org.hibernate.annotations.Filter(name="time", condition=":adTime >= insertTime" 
     private Set<Ad> ads; 
     ... 
    )

而且通过source

@Table(name="filters") 
@FilterDef(name="time", parameters={ 
    @ParamDef(name="adTime", type="date") 
}) 
@Filters({ 
    @org.hibernate.annotations.Filter(name="time", condition=":adTime >= insertTime") 
}) 
    public class Filter { 
      ... 
      @ManyToMany(cascade=CascadeType.ALL) 
      private Set<Ad> ads; 
      ... 
     )

广告尝试像类级别的注释使用

public GeUser getUser(int id){ 
    Criteria criteria = session.createCriteria(GeUser.class); 
    DateTime dt = new DateTime(); 

    // set up filter 
    session.enableFilter("time").setParameter("adTime", dt.minusDays(7).toDate()); 

    criteria.add(Restrictions.eq("id",id)); 
    @SuppressWarnings("unchecked") 
    List<GeUser> results = criteria.list(); 
    if(results.size()<1)return null; 
    return results.get(0); 
}

也试过：

public GeUser getUser(int id){ 
    DateTime dt = new DateTime(); 
    // enable filter top of createCriteria method 
    session.enableFilter("time").setParameter("adTime", dt.minusDays(7).toDate()); 

    Criteria criteria = session.createCriteria(GeUser.class); 
    criteria.add(Restrictions.eq("id",id)); 
    @SuppressWarnings("unchecked") 
    List<GeUser> results = criteria.list(); 
    if(results.size()<1)return null; 
    return results.get(0);

}

我也试过明确会议召开之前建立新的查询，但后来我得到assertEquals(1, u.getFilters().size());

java.lang.AssertionError: expected:<1> but was:<0>

有明确的会议DAO方法的底部例外：

public GeUser getUser(int id){ 
    this.session.clear(); 
    DateTime dt = new DateTime(); 
    session.enableFilter("time").setParameter("adTime", dt.minusDays(7).toDate()); 
    Criteria criteria = session.createCriteria(GeUser.class); 
    criteria.add(Restrictions.eq("id",id)); 
    @SuppressWarnings("unchecked") 
    List<GeUser> results = criteria.list(); 
    if(results.size()<1)return null; 
    return results.get(0); 
}

我已经删除了我以前的建议为答案，因为，你是对的，这不是：你必须更新关联的拥有方，反方（含mappedBy一）未与数据库同步不解决你的问题。你有没有尝试过这种方法？ http://www.concretepage.com/hibernate/hibernate-filter-and-filterjointable-annotation-example在这些示例中，过滤器（和filterjointable）在实体中定义，而不是分离的类。 – RubioRic

我试着添加Filter注解到类的级别，不工作。 –

使用@Filter而不是@FilterJoinTable：

@ManyToMany(cascade=CascadeType.ALL) 
@Filter(name="time", condition=":adTime >= insertTime") 
private Set<Ad> ads;

从documentation：

When the collection use an association table as a relational representation, you might want to apply the filter condition to the association table itself or to the target entity table. To apply the constraint on the target entity, use the regular @Filter annotation. However, if you want to target the association table, use the @FilterJoinTable annotation.

其次，你似乎没有在初始设置后关闭会话，所以你的实体实例保持在第一级缓存（意味着具有2个元素的初始集合仍然在缓存中并从那里返回）。

既可以在测试方法一个新的会话，或者在查询执行前清除现有的一个：

session.clear();

第三，看看this answer。

public void addFilter(Filter filter){ 
    this.filters.add(filter); 
    filter.setUser(this); 
}

不工作，看帖子。 –

@EdgarasKarka请参阅编辑答案。 –

@DrganBozanovic我尝试清除会话，但现在获取user.filters设置的大小0。查看编辑过的帖子。 –
