Question

我在查找表中有一个数据列表，我正在尝试使用ehcache进行缓存。我注意到缓存正在正确填充数据，但是当我在条件查询中使用.add（Restrictions.like（“name”，“Fritz％”））时，它似乎没有达到二级缓存。有没有办法配置ehcache使用字符串值而不仅仅是Id？

查看缓存

查询示例

List cats = sess.createCriteria(Cat.class)
    .add( Restrictions.like("name", "Fritz%") )
    .setCacheable(true)
    .list();

的hibernate.cfg.xml

    <!-- Enable Second-Level Cache and Query Cache Settings --> 
    <property name="hibernate.cache.use_second_level_cache">true</property>         
    <property name="hibernate.cache.use_query_cache">true</property>
    <property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>         
    <property name="hibernate.generate_statistics">false</property>

实体

@Entity
@org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Cat implements Serializable {

private String name;

ehcache + Hibernate + hibernate Restrictions.like查询
