JBOSS---ESB 序列之四 helloworld_ftp_action详细介绍

[color=red][b]helloworld_ftp_action 展示了如何利用 FtpGateway 来 循环 监听 远程ftp服务器上特定目录下 指定后缀的文件的处理过程[/b][/color]
这对一些以在远程ftp服务器上以文件为接口方式的集成，特别有用

[b]1. Esb 配置文件[/b]

[b]2. 需要定义三个providers[/b]
1. ftp-provider 提供ftp功能
2. jms-provider 提供jms消息队列
3. schedule-provider 指定调度频率

[b]3. 需要定义两个listeners[/b]
1. ftp 网关监听器
2. jms-bus 监听器

[b]4. action 只是打印文件的内容[/b]
