spring 几个有用的类

public class ApplicationContextUtil implements ApplicationContextAware {
	
	Logger logger = LoggerFactory.getLogger(ApplicationContextUtil.class);

	public static Map<String, CamelContext> map;
	
	@Override
	public void setApplicationContext(ApplicationContext applicationContext)
			throws BeansException {
		map = applicationContext.getBeansOfType(CamelContext.class);
		//getBeansOfType  返回bean的实例匹配给定的对象类型（包括子类），
	}
}

public class ChannelBetListener implements ApplicationListener<ContextRefreshedEvent>{
	private static Logger logger=LoggerFactory.getLogger(ChannelBetListener.class);
	@Resource(name="channelCamelContext")
	CamelContext camelContext;
	@Produce
	private ProducerTemplate drawProducer;
	@Override
	public void onApplicationEvent(ContextRefreshedEvent event) {
		try{
			//加载配置文件后所干的事
		}catch(Exception e){
			e.printStackTrace();
		}

	}
}

@Configuration
public class MinaConfiguration {
 public @Bean IoAcceptor ioAcceptor(){
	 return new NioSocketAcceptor();
 }
 public @Bean LoggingFilter loggingFiler(){
	 return new LoggingFilter();//相当于<bean id="" class=""></bean>
 }
 public @Bean ProtocolCodecFilter protocolCodecFilter(){
	 return  new ProtocolCodecFilter(new TextLineCodecFactory(Charset.forName("UTF-8")));
 }
}
