1、首先把對映關係放在spring-mvc.xml配置檔案

<bean id="dispatcher" class="com.ms.kai.bms.dispatcher.AbstractDispatcherImpl">
		<property name="serviceMap">
			<map>
				<entry key="10001" value-ref="serviceAImpl"/>
				<entry key="10002" value-ref="serviceBImpl"/>
				<entry key="10003" value-ref="serviceCImpl"/>			
			</map>
		</property>
	</bean>
 

2、程式碼實現

@Service("dispatcher")
public class AbstractDispatcherImpl 
{
    private Map<Integer, Iservice> serviceMap = new HashMap<Integer, Iservice>();

    @Override
    public RestoreDto dispatcherDraw(String key)
    {
        Iservice service = getServiceMap.get("10001");
        return service.query();
    }

    public Map<Integer, Iservice> getServiceMap()
    {
        return serviceMap;
    }

    public void setServiceMap(Map<Integer, Iservice> serviceMap)
    {
        this.serviceMap = serviceMap;
    }

}
 

public interface Iservice
{
    public void query();
}

@Component("serviceAImpl")
public class ServiceAImpl implements Iservice
{
@Override
public void query(){
		
}
}

@Component("serviceBImpl")
public class ServiceBImpl implements Iservice
{
@Override
public void query(){
		
}
}
