定时扫描特定目录的rss文件:

 

轮询特定的路径:

 

 

定期从jms发送rss文件信息,并读取:

 

 

手动生成rss文件:

 

 

package com.easyway.esb.mule.rss;

import org.mule.api.annotations.param.Payload;

import com.sun.syndication.feed.synd.SyndEntry;

import java.util.concurrent.atomic.AtomicInteger;
/**

 * @author longgangbai

 */
public class EntryReceiver
{
    private AtomicInteger count = new AtomicInteger(0);

    public void readEntry(@Payload SyndEntry entry) throws Exception
    {
        count.getAndIncrement();
    }

    public int getCount()
    {
        return count.get();
    }
}

 

 

package com.easyway.esb.mule.rss;

import org.mule.api.annotations.param.Payload;

import com.sun.syndication.feed.synd.SyndFeed;

import java.util.concurrent.atomic.AtomicInteger;
/**
 * 
 * @author longgangbai

 */
public class FeedReceiver
{
    private AtomicInteger count = new AtomicInteger(0);

    public void readFeed(@Payload SyndFeed feed) throws Exception
    {
        count.set(feed.getEntries().size());            
    }

    public int getCount()
    {
        return count.get();
    }
}
