步骤 2：为新的相反证据转换实现添加绑定

使用 Guice 绑定注册实现。

  
public class SampleModule extends AbstractModule {

  public void configure() {      

    MapBinder<CASEEVIDENCEEntry, ReciprocalEvidenceConversion> recEvidenceConversionMapBinder = 
      MapBinder.newMapBinder(binder(), CASEEVIDENCEEntry.class, ReciprocalEvidenceConversion.class);
 
    reciprocalEvidenceConversionMapBinder.addBinding(
	  CASEEVIDENCEEntry.get("WORKINGRELATIONSHIP")).to(
      SampleWorkingRelationshipReciprocalConversion.class);
  }
}
