有输入与输出参数的存储过程

oracle存储过程部分代码：

create or replace procedure PT_copy_Shipment_One_Data(

  oldShipmentId in  varchar ,

  servprovGid in varchar ,

  insertUser in varchar,

  resultShipmentId out varchar

)is

 newShipmentGid varchar2(50 );

 newShipmentXid varchar2(50 );

 newShipmentTypeGid varchar2(50 );

begin

          --执行的PLSQL体

commit;--提交事物

Exception

   When others then

      Rollback;

end  PT_copy_Shipment_One_Data;

mybatis的Xml配置

注意：虽然有返回值，不需要知道设置返回参数类，详情可看下面java代码例子

<select  id= "callCoptShipment" parameterType ="map"  

           statementType="CALLABLE">

{call PT_copy_Shipment_One_Data(

#{oldShipmentId,mode=IN,jdbcType=VARCHAR},

#{servprovGid,mode=IN,jdbcType=VARCHAR},

#{insertUser,mode=IN,jdbcType=VARCHAR},

#{resultShipmentId,mode=OUT,jdbcType=VARCHAR}

)} 

     ]]> 

select >

Dao或者Service代码

Map parasMap = new HashMap();

parasMap.put("oldShipmentId", para.get( "shipmentId"));

parasMap.put( "servprovGid", para.get("skdw"));//attr12

parasMap.put( "insertUser", Users.getCurrent());

parasMap.put( "resultShipmentId", "" );

//调用存储过程

  this.getSqlSessionTemplate().

selectOne("com.otm.app.entity.pojo.ShipmentCost.callCoptShipment",parasMap);

parasMap.put("shipmentId", parasMap.get("resultShipmentId" ));

return parasMap;

如上标红的代码，在mybatis不需要设置返回参数，然后在java当中调用存储过程也不需要接受返回参数，map参数当中会自动有。这是一个奇怪的地方。
