mybatis调用oracle存储过程

存储过程：

create or replace procedure JDGL_PRO_GET_DFLZJSBB3(p_date1 in varchar2, res OUT sys_refcursor) is

  begin
    
  open res for
    SELECT COUNT(1)            AS COL1,
           COUNT(null)         AS COL2
      FROM XFAJ09 A
     WHERE A.DELETEFLAG = '0'
       AND A.XFAJ0907 BETWEEN TO_DATE('2017-11-01', 'yyyy-mm-dd')
                          AND TO_DATE('2017-11-30', 'yyyy-mm-dd')
       AND EXISTS (
                    SELECT DMCOD
                      FROM G099_HIBER GH
                     WHERE (GH.DMPARENTCOD = 'b8652adc-e096-47e1-88fe-d14dbf7b3f9e'
                            OR GH.DMCOD = 'b8652adc-e096-47e1-88fe-d14dbf7b3f9e')
                       AND GH.DMCOD = A.CREATEUSERDEPT
                  );
                  
end JDGL_PRO_GET_DFLZJSBB3;

xml文件：

    <select id="countDFLZAN" parameterType="string" resultType="java.util.LinkedHashMap" statementType="CALLABLE">
                  {call JDGL_PRO_GET_DFLZJSBB3(#{date1,mode=IN,jdbcType=VARCHAR},#{result,mode=OUT,jdbcType=CURSOR})}
    </select>

Java代码：

    @Action
    public String selectBB3(){
        HttpServletRequest request = ActionContext.getActionContext()
                .getHttpServletRequest();
        Map<String, Object> map = new HashMap<String, Object>();

        Map<String, Object> params = new HashMap<String, Object>();
        params.put("date1", "2017-11-01");
        params.put("result", null);
        bdsoftMybatisUtils.selectList("jdgl.dflzjsbb.countDFLZAN", params);
        ResultSet set = (ResultSet)params.get("result");
        try {
            while (set.next()) {
                System.out.println(set.getString("COL1"));
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        
        return Json.encode(map);
    }
