Ah, looked for a long time Baidu, unexpectedly there is no direct example ... Own reference to other examples, wrote a ...

Other ignores, directly on the key code:

Pojo class:

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 Interface:

Public interface Departmentmapper {//query returns a listpublic list<department> queryalldepartment ();}

Mapper the corresponding configuration file:

<!--here namespace need to specify DAO interface--><mapper namespace= "Com.mymaven.mybatisdemo.dao.DepartmentMapper" >    <!--Configure a resultmap to specify the type returned--    <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>    <!--returns a list of the notation--    <select id=" Queryalldepartment "  resultmap=" departMent ">        select * from T_department    </select>   </ Mapper>

Attention

<select id= "queryalldepartment"  resultmap= "DepartMent" Here the return type is Resultmap, not resulttype. I got it wrong.
