关于ibatis sqlmapping 关联的写法

1 一对多关联 配置文件如下：
<sqlMap namespace="User">
<typeAlias alias="user" type="com.ibatis.sample.User"/>
<typeAlias alias="address" type="com.ibatis.sample.Address"/><resultMap id="get-user-result" class="user">
<result property="id" column="id"/>
<result property="name" column="name"/>
<result property="sex" column="sex"/>
<result property="addresses" column="id"
select="User.getAddressByUserId"/>
</resultMap><select id="getUsers"  
parameterClass="java.lang.String"
resultMap="get-user-result">
<![CDATA[
select
id, 
name,
sex
from t_user
where id = #id#
]]>
</select><select id="getAddressByUserId"
parameterClass="int"
resultClass="address">
<![CDATA[
select
address,
zipcode
from t_address
where user_id = #userid#
]]>
</select>
</sqlMap>
代码
String resource ="com/ibatis/sample/SqlMapConfig.xml";Reader reader;
reader = Resources.getResourceAsReader(resource);XmlSqlMapClientBuilder xmlBuilder = new XmlSqlMapClientBuilder();
sqlMap = xmlBuilder.buildSqlMap(reader);
//sqlMap系统初始化完毕List userList = sqlMap.queryForList("User.getUsers", "");for (int i = 0; i < userList.size(); i++) {
User user = (User)userList.get(i);
System.out.println("==>" + user.getName());
for (int k = 0; k < user.getAddresses().size(); k++) {
Address addr = (Address) user.getAddresses().get(k);
System.out.println(addr.getAddress());
}
}
