Java Bean属性“bagBisDomainService”不可写或具有无效的setter方法

我有一个Bean属性“bagBisDomainService”不可写，或者在执行SpringWeb应用程序时出现无效的setter方法错误。下面是我的代码：

public class StatusSynthesisFlightsAction extends WDispatchAction {

protected FlightListeCritereForm criteriaForm = null;

/**
 * Reference sur le domain service
 */
private BagDS bagBisDomainService;

/**
 * Reference sur le domain service
 */
 private FlightDS flightBisDomainService;

 /**
  * @return the bagBisDomainService
  */
 public BagDS getBagBisDomainService() {
     return bagBisDomainService;
 }


 /**
  * @param bagBisDomainService the bagBisDomainService to set
  */
 public void setBagBisDomainService(BagDS bagBisDomainService) {
     this.bagBisDomainService = bagBisDomainService;
 }


 /**
  * @return the flightDomainService
  */
 public FlightDS getFlightBisDomainService() {
     return flightBisDomainService;
 }

}

有什么想法吗

提前感谢

1清洁后重新构建并尝试。

2公共类StatusSynthesisFlightsAction扩展了WDispatchAction，如果1失败，则实现可序列化

是否有setFlightBisDomainService方法？@indybee是的，有setFlightBisDomainService方法。但我明白了，问题来自我的struts-config.xml。下面是解释。

<bean name="/statusSynthesisFlights" class="com.afklm.srbview.applicationlayer.action.flight.StatusSynthesisFlightsAction" scope="singleton">
    <property name="bagBisDomainService" ref="bagDSImpl"/>
    <property name="flightBisDomainService" ref="flightDSImpl"/>
</bean>
