MyBatis调用存储过程返回多条数据结果集
需求：执行存储过程返回三条数据结果集返回前端
执行存储过程效果如下所示：
三种数据分别代表盘点盈余，盘点亏损，盘点正常，最终实现结果：
现要求一个接口返回三种数据
Service层
List<List<?>> queryCaleResult(Map map);
Mapper文件
用于调用存储过程返回最终结果
<parameterMap id="pm" type="java.util.Map">
<parameter property="inventoryId" jdbcType="INTEGER" mode="IN"/>
<parameter property="inventoryMode" jdbcType="INTEGER" mode="IN"/>
</parameterMap>
<select id="queryCaleResult" parameterMap="pm" statementType="CALLABLE" resultMap="VAssetInventoryScan,VAssetStock,VAssetInventoryScan"
resultType="java.util.List">
<![CDATA[
{
call dbo.CalcInventoryResult(
#{
inventoryId,mode=IN, jdbcType=INTEGER},
#{
inventoryMode,mode=IN,jdbcType=INTEGER}
)
}
]]>
</select>
解释说明：
parameterMap 为参数列表，调用存储过程需要statementType=“CALLABLE”，resultMap为定义映射返回结果视图，可跟多个用逗号分隔 ，具体如下
<resultMap type="com.example.phonegd.inventory.pojo.VAssetInventoryScan" id="VAssetInventoryScan">

注意：这里需要注意的地方，property不能省略，否则会数据全为null，type为对应的实体类，类似下图
Controller层
@PostMapping("/caleResult")
public BaseResponse queryCaleResult(@RequestBody Map map){
BaseResponse response= null;
try {
response = new BaseResponse(StatusCode.Success);
Map mm=new HashMap();
List<List<?>> result=null;
if(Integer.parseInt(String.valueOf(map.get("inventoryMode")))==1){
result = inventoryService.queryCaleResult(map);
mm.put("VAssetInventoryScan",result.get(0));
mm.put("VAssetStock",result.get(1));
mm.put("VAssetInventoryNormal",result.get(2));
}else if(Integer.parseInt(String.valueOf(map.get("inventoryMode")))==2){
result = inventoryService.queryCaleResult2(map);
mm.put("VAssetInventoryScan",result.get(0));
mm.put("VAssetStock",result.get(1));
mm.put("VAssetInventoryNormal",result.get(2));
}
response.setData(mm);
} catch (NumberFormatException e) {
response=new BaseResponse(StatusCode.SysBusy);
}
return response;
}
