Mybatis调用Oracle返回结果集存储过程
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：
