private Long id;<br /> private String username;<br /> private String password;<br /> private Map<String,String> phone = new HashMap<String,String>() ;

一个用户有多个电话，需要以map形式存取

<map name="phone" table="userphone" order-by="phone_number"><br /> <key column="userid" foreign-key="id"></key><br /> <map-key type="java.lang.String" column="phone_type"></map-key><br /> <element type="java.lang.String" column="phone_number"></element><br /> </map>

在配置文件里面map需要配置key和value 对应hibernate里面的 <map-key>和<element>
