mybatis 调用存储过程返回游标实例

存储过程示例： 
    create or replace procedure Fsp_Plan_CheckPrj(v_grantno  varchar2, v_deptcode number,  v_cursor   out sys_refcursor) is 
    ……………… 
        ---返回统计结果 
        open v_Cursor for 
          select s.plan_code, 
                 s.plan_dept, 
                 s.plan_amount, 
                 s.exec_amount, 
                 p.cname       as plan_name, 
                 d.cname       as dept_name 
            from Snap_plan_checkprj s 
            left join v_plan p 
              on s.plan_code = p.plan_code 
            left join org_office d 
              on s.plan_dept = d.off_org_code 
           group by s.plan_code, 
                    s.plan_dept, 
                    s.plan_amount, 
                    s.exec_amount, 
                    p.cname, 
                    d.cname; 
      end; 
    end Fsp_Plan_CheckPrj;

mybatis:（mybatis doc api：  http://mybatis.github.io/mybatis-3/zh/sqlmap-xml.html\#Result\_Maps）

java层代码

Map<String, Object> params = new HashMap<String, Object>();
    GrantSetting gs = this. grantSettingDao.get(grantCode);
    params.put( "grantNo", StringUtils. substring(gs.getGrantNo(), 0, 2));
    params.put( "offOrgCode", SecurityUtils.getPersonOffOrgCode());
    
    params.put("v_cursor", new ArrayList<Map<String, Object>>());//传入一个jdbc游标，用于接收返回参数
    this. batisDao. getSearchList("call_Fsp_Plan_CheckPrj", params);

mybatis xml配置

<resultMap type ="java.util.HashMap" id= "cursorMap"><！--配置返回游标中别名对应的resultMap -->
         <result column ="plan_code" property="plan_code" />
         <result column ="plan_dept" property="plan_dept"  />
         <result column ="plan_amount" property="plan_amount" />
         <result column ="exec_amount" property="exec_amount"  />
         <result column ="plan_name" property="plan_name" />
         <result column ="dept_name" property="dept_name" />
    </resultMap >
    <select id ="call_Fsp_Plan_CheckPrj" parameterType= "map" statementType="CALLABLE" >
                                                             
         {call Fsp_Plan_CheckPrj(#{grantNo, jdbcType=VARCHAR, mode=IN},
                                       #{offOrgCode, jdbcType=INTEGER, mode=IN},
         #{v_cursor, mode=OUT, jdbcType=CURSOR, resultMap=cursorMap})}
    
    </select >

最后，在jsp页面只需遍历   
params.put( "v\_cursor", OracleTypes. CURSOR);中的v\_cursor。本身就是一个可遍历的list结果集
