Oracle嵌套表作爲Mybatis存儲過程的輸入參數

Question

我需要使用Mybatis調用具有嵌套表類型的輸入參數的Oracle存儲過程。

我找不到有關MyBatis的這種特定用法的任何文檔或示例。

有沒有人做過這個，或看過一個例子？

非常感謝。

讓我們這個例子：

程序PROCEDURERECORD （P_VAL_REC IN Package.RECORD ，P_VAL_NUM IN VARCHAR2 ，P_DAT_VAL過時 ）;

在你的數據庫重新定義SP：

程序PROCEDURERECORD_NEW （P_VAL_REC IN RECORD_TYPE（你的類型創建它） ，P_VAL_NUM IN VARCHAR2 ，P_DAT_VAL過時 ）;

你應該重新配置你SP豆與春天：

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd       http://www.springframework.org/schema/util        http://www.springframework.org/schema/util/spring-util.xsd"> 

<bean id="PROCEDURERECORD_NEW" parent="storedProcedure"> 
    <constructor-arg index="0" value="PROCEDURERECORD" /> 
    <constructor-arg index="1" value="false" /> 
    <property name="params"> 
     <list> 
      <bean parent="sqlRecordParamIn"> 
       <constructor-arg index="0" value="P_VAL_REC" /> 
       <constructor-arg index="2" value="RECORD_TYPE" /> 
      </bean> 
      <bean parent="sqlNumericParamIn"> 
       <constructor-arg value="P_VAL_NUM" /> 
      </bean> 
      <bean parent="sqlDateParamOut"> 
       <constructor-arg value="P_DAT_VAL"/> 
      </bean> 
     </list> 
    </property> 
</bean> 

在您的實現代碼，使用SqlStructValue這樣的：

@Override 
public DateTime getSpReturn(RecordClass record,Long valNum){ 
    Map<String, Object> args = new HashMap<String, Object>(); 
    args.put("P_VAL_REC", new SqlStructValue<RecordClass>(record,new RecordClassMapper())); 
    args.put("P_VAL_NUM", valNum); 


    Map<String, Object> result = procedureRecordNew.execute(args); 
    return (DateTime)result.get("P_DAT_VAL"); 
} 

至於映射器創建它像這樣：

@Component("RecordClassMapper") 
public class RecordClassMapper implements StructMapper<RecordClass> { 

@Override 
public STRUCT toStruct(RecordClass source, Connection conn, String typeName) throws SQLException { 
    Object[] objectProperties = new Object[] { new source.getrecordatr1(), source.getrecordatr2(), source.getrecordatr3() }; 
    return new STRUCT(new StructDescriptor(typeName, conn), conn, objectProperties); 
} 

@Override 
public RecordClass fromStruct(STRUCT struct) throws SQLException { 
    // Auto-generated method stub 
    throw new UnsupportedOperationException("Not implemented"); 
} 

}
