Java Castor:为具有抽象属性的类创建映射文件

Java Castor:为具有抽象属性的类创建映射文件,java,spring,castor,Java,Spring,Castor,我有这门课: public class Source extends Node { protected DistributionSampler delay ; protected DistributionSampler batchsize ; /** * @param name The name of the source node * @param d The {@link DistributionSampler} used to generate the *

我有这门课:

public class Source extends Node {
  protected DistributionSampler delay ;
  protected DistributionSampler batchsize ;


/**
 * @param name The name of the source node
 * @param d The {@link DistributionSampler} used to generate the
 *          inter-arrival times
*/
  public Source( String name, DistributionSampler d ) {
    super( name ) ;
    delay = d ;
    batchsize = new Deterministic( 1 ) ;
    Sim.schedule( new Arrival( Sim.now() + delay.next() ) ) ;
  }

/**
 * @param name The name of the source node
 * @param d The {@link DistributionSampler} used to generate the
 *          inter-arrival times
 * @param b The {@link DistributionSampler} used to generate the
            batch sizes
*/
  public Source( String name, DistributionSampler d, DistributionSampler b ) {
    super( name ) ;
    delay = d ;
    batchsize = b ;
    Sim.schedule( new Arrival( Sim.now() + delay.next() ) ) ;
  }

   ....
}
DistributionSampler是一个抽象类

在将XML转换为Java对象时,我将知道要使用抽象类的哪个具体实现(通过bean名称)

但是,我不完全确定如何编写映射文件来告诉castor如何进行转换

任何帮助都将不胜感激


<class name="network.Source">
        <description xmlns="">
            Default mapping for class network.Source
        </description>

        <map-to xml="Source"/>

        <field name="name" type="java.lang.String" required="true">
            <bind-xml  node="element" />
        </field>

        <field name="delay" type="tools.DistributionSampler" required="true" set-method="initialiseDelay" get-method="getDelay">
            <bind-xml  auto-naming="deriveByClass" node="element" location="delay"/>
        </field>

        <field name="batchSize" type="tools.DistributionSampler">
            <bind-xml  auto-naming="deriveByClass" node="element" location="batchSize"/>
        </field>
    </class>
类网络的默认映射。源
auto naming=“deriveByClass”部分意味着,如果我们发送它,它将把delay中嵌入的元素的节点名绑定到一个它希望扩展distributionSampler的等效类

因此,我们很高兴处理以下xml:

<Source name="asd">
    <delay>
        <Deterministic time="234" />
    </delay>

    <batchSize>
        <Erlang K="234" Theta="234" />
    </batchSize>
</Source>

将使用Deterministic和Erlang的映射文件将其映射到扩展DistributionSampler的类实例。
