Question

Oracle存储过程：

create or replace PROCEDURE "TGT_MPD_PLANOGRAM_SEL_SP" (
    POG_NUM_IN IN VARCHAR2,
    PLAN_DATA_SEL_CUR OUT SYS_REFCURSOR,
    SQL_CODE_OUT OUT NUMBER,
    SQL_ERR_MSG_OUT OUT VARCHAR2)
AS
...

Mapper.xml

<select id="getPlanograms" statementType="CALLABLE"
        parameterType="com.tgt.snp.pog.vo.PlanogramSearchVO"
        resultMap="mapResultPlanogram">
    {
        CALL TGT_MPD_PLANOGRAM_SEL_SP(
            #{POG_NUM_IN,javaType=String,jdbcType=VARCHAR,jdbcTypeName=VARCHAR2,mode=IN},
            #{PLAN_DATA_SEL_CUR,jdbcType=CURSOR,resultMap=mapResultPlanogram,mode=OUT},
            #{SQL_CODE_OUT,javaType=Integer,jdbcType=INTEGER,jdbcTypeName=INTEGER,mode=OUT},
            #{SQL_ERR_MSG_OUT,javaType=String,jdbcType=VARCHAR,jdbcTypeName=VARCHAR2,mode=OUT}
        )
    }
</select>

VO对象

public class PlanogramSearchVO {

    public PlanogramSearchVO(){}
public String getPOG_NUM_IN() {
        return POG_NUM_IN;
    }

    public void setPOG_NUM_IN(String POG_NUM_IN) {
        this.POG_NUM_IN = POG_NUM_IN;
    }

    private String POG_NUM_IN;

    public ResultSet getPLAN_DATA_SEL_CUR() {
        return PLAN_DATA_SEL_CUR;
    }

    public void setPLAN_DATA_SEL_CUR(ResultSet PLAN_DATA_SEL_CUR) {
        this.PLAN_DATA_SEL_CUR = PLAN_DATA_SEL_CUR;
    }

    private ResultSet PLAN_DATA_SEL_CUR;

    public Integer getSQL_CODE_OUT() {
        return SQL_CODE_OUT;
    }

    public void setSQL_CODE_OUT(Integer SQL_CODE_OUT) {
        this.SQL_CODE_OUT = SQL_CODE_OUT;
    }

    private Integer SQL_CODE_OUT;

    public String getSQL_ERR_MSG_OUT() {
        return SQL_ERR_MSG_OUT;
    }

    public void setSQL_ERR_MSG_OUT(String SQL_ERR_MSG_OUT) {
        this.SQL_ERR_MSG_OUT = SQL_ERR_MSG_OUT;
    }

    private String SQL_ERR_MSG_OUT;
}

请指出我错了什么？提前谢谢。

<select>元素不需要resultMap属性，因为这里没有使用它：调用带有out参数的过程，即使它们是cursor / resultSet，也不是 SELECT < / em>的

您可能需要在参数定义中将java类型指定为结果集：

#{PLAN_DATA_SEL_CUR, jdbcType=CURSOR, javaType=java.sql.ResultSet, resultMap=mapResultPlanogram, mode=OUT}

类PlanogramSearchVO中的属性PLAN_DATA_SEL_CUR不能是java.sql.ResultSet，而是List<Planogram>，如果结果映射mapResultPlanogram将游标结果映射到Planogram对象

Mybatis正在完成将resultSet / Cursor读取/映射到对象列表的工作;缺点是只有在光标被完全取出时才返回控件：没有自定义结果处理，懒惰/不同加载，......我有answered another question about this。

如何将光标的MyBatis映射器配置为输出参数？
