ibatis在編寫sqlmap的查詢時，可以使用多種輸出格式，比如：實體類，hashmap，xml格式。
sqlmap中的hashmap和xml都是內置別名。
1.實體類：
<resultMap id="UserResult"
class="User">
<result property="id" column="T_ID"/>
<result property="name" column="T_NAME"/>
<result property="sex" column="T_SEX"/>
<result property="address" column="T_ADDRESS"/>
</resultMap>
<select id="selectAllUser" resultMap="UserResult"> select * from t_user </select>
List list = userdao.selectAllUser(); for(int
i=0;i<list.size();i++) { System.out.println(list.get(i)); }
注：當作一個對象使用。
2.hashmap:
<select id="selectAllUser"
resultClass="hashmap"> select * from t_user </select>
List list = userdao.selectAllUser();
for(int i=0;i<list.size();i++) {
Map map = (Map)list.get(i);
System.out.print(map.get("id")+" ");
System.out.print(map.get("name")+" ");
System.out.print(map.get("sex")+" ");
System.out.print(map.get("address"));
System.out.println();
}
注：當作一個鍵值對的MAP使用。
3.XML：
<select id="selectXML"
resultClass="xml" xmlResultName="log"> select * from t_user </select>
List list = userdao.selectAllUser();
for(int i=0;i<list.size();i++) {
System.out.println(list.get(i));
}
XML結果：
< xml version="1.0" encoding="UTF-8"
><log><id>1</id><name>hua</name><sex>1</sex><address>1</address></log>
< xml version="1.0" encoding="UTF-8"
><log><id>2</id><name> zhupan
</name><sex>2</sex><address>1</address></log>
< xml version="1.0" encoding="UTF-8"
><log><id>4</id><name> 4
</name><sex>4</sex><address>1</address></log>
< xml version="1.0" encoding="UTF-8"
><log><id>5</id><name> 5
</name><sex>5</sex><address>2</address></log>
