哎,查了很久百度,竟然沒有直接的例子... 自己參考其他例子,寫了一個...
其他的忽略,直接上關鍵代碼:
pojo 類:
package com.mymaven.mybatisdemo.po;
public class Department {
private String dp_id;
private String dp_name;
private String cost_center;
public String getDp_id() {
return dp_id;
}
public void setDp_id(String dp_id) {
this.dp_id = dp_id;
}
public String getDp_name() {
return dp_name;
}
public void setDp_name(String dp_name) {
this.dp_name = dp_name;
}
public String getCost_center() {
return cost_center;
}
public void setCost_center(String cost_center) {
this.cost_center = cost_center;
}
public Department() {
super();
}
}
mapper接口:
public interface DepartmentMapper {
//查詢返回一個list
public List<Department> queryAllDepartment();
}
mapper對應的配置文件:
<!-- 此處namespace需要指定dao接口 -->
<mapper namespace="com.mymaven.mybatisdemo.dao.DepartmentMapper">
<!--配置一個resultMap 指定返回的類型 -->
<resultMap id="departMent" type="Department">
<id column="dp_id" property="dp_id" />
<result column="dp_name" property="dp_name" />
<result column="cost_center" property="cost_center" />
</resultMap>
<!-- 返回一個list的寫法 -->
<select id="queryAllDepartment" resultMap="departMent" >
select * from t_department
</select>
</mapper>
