Hibernate集合映射Set和Map
Set和Map基本和List一样先看Set?? 只需要将List改为private Set emails = new HashSet(0);然后修改User.hbm.xml文件就可以了
<set name="emails" table="emails"><key column="userid" foreign-key="id" /><element type="string" column="email" /></set>

再看Map? 同样的? private Map emails = new HashMap();<map name="emails" table="email"><key column="userid" foreign-key="id" /><map-key column="sb" type="string" /><element column="email" type="string" /></map>
?
