Mapper.xml 配置

<resultMap type="emp" id="empMap">

<id property="empno" column="empno"/>

<result property="ename" column="ename"/>

<result property="mgr" column="mgr"/>

<result property="job" column="job"/>

<result property="hiredate" column="hiredate"/>

<result property="sal" column="sal"/>

<result property="comm" column="comm"/>

</resultMap>

<!-- 调用存储过程返回结果集 -->

<select id="getEmps" parameterType="java.util.Map" statementType="CALLABLE">

<![CDATA[

call pro_emp(#{emps,mode=OUT,jdbcType=CURSOR,javaType=java.sql.ResultSet,resultMap=empMap})  ]]>

</select>

存储过程：

create or replace procedure pro_emp(cur_sys out sys_refcursor)

as

begin

open cur_sys for select empno, ename, job, mgr, hiredate, sal, comm, deptno

from tb_emp;

end;

IOperation接口里的方法 ：

public interface IOperation {

void getEmps(Map<String, Object> param);

}

测试类：

public class Mytest {

private SqlSession sqlSession;

private IOperation mapper;

@Before

public void before(){

try {

SqlSessionFactory factory=MyBatisUtil.getSqlSessionFactory();

sqlSession=factory.openSession();

mapper=sqlSession.getMapper(IOperation.class);

System.out.println("start");

} catch (Exception e) {

System.out.println(e.getMessage());

}

}

@Test

public void getEmps(){

try {

Map<String, Object> param = new HashMap<String, Object>();

param.put("emps",OracleTypes.CURSOR);

mapper.getEmps(param);

List<Emp> depts =(List<Emp>)param.get("emps");

for (Emp emp : depts) {

System.out.println(emp.getEmpno()+" "+emp.getEname());

}

} catch (Exception e) {

System.out.println("getEmp: "+e.getMessage());

}

}

@After

public void after(){

System.out.println("close");

sqlSession.close();

}

}

结果：
