spring map注入的使用

spring-cfg.xml文件配置:

<bean id="iAlarmHandlerInfoMap" class="com.boco.cfg.IAlarmHandlerInfoMap" scope="prototype">
	<property name="mapping">
		<map>
			<entry key="slaPreAlarmHandlerInfo">
				<bean class="com.boco.impl.AlarmHandlerInfoImpl"></bean>
			</entry>
		</map>
	</property>
</bean>

　　映射配置文件的的Map对象:

public class IAlarmHandlerInfoMap {
	
	private Map<String, IAlarmHandlerInfo> mapping;

	public Map<String, IAlarmHandlerInfo> getMapping() {
		return mapping;
	}

	public void setMapping(Map<String, IAlarmHandlerInfo> mapping) {
		this.mapping = mapping;
	}
	
}

　　通过map注入获取对应的类实例:

className============"slaPreAlarmHandlerInfo"
public IAlarmHandlerInfo getIAlarmHandlerInfoByClassName(String className){
	IAlarmHandlerInfo alarmHandler = null;
	if(className != null){
	　　IAlarmHandlerInfoMap iaphMap = (IAlarmHandlerInfoMap)util.getBean("iAlarmHandlerInfoMap");
	　　alarmHandler = iaphMap.getMapping().get(className);
	}else{
	　　log.error("输入的类名称为空！");
	}
	alarmHandler.setSubClassName(className);//返回对象前将实例化子类类名设置好
	return alarmHandler;
}
