JBOSS---ESB 序列之三 helloworld_file_action详细介绍

[color=red][b]helloworld_file_action 展示了如何利用 FileGateway 来 循环 监听 特定目录下 指定后缀的文件的处理过程[/b][/color]
这对一些以文件为接口方式的集成，特别有用

[b]2. Provider:[/b]
fs-provider 文件provider，主要用来在本地指定目录、指定后缀的文件，将文件的内容作为消息发送到 Service 的 esb bus(该例子是 quickstartEsbChannel )上去。
jms-provider 用来定义 Service 的 esb bus 的消息队列

[b]3. 配置了 FileGateway listener 和 bus listener 监听器 分别 监听 文件 和 消息队列[/b]

[b]4. 自定义Action只是打印文件的内容[/b]
