篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Camel FTP error:File operation failed: 150 Here comes the directory listing相关的知识,希望对你有一定的参考价值。

问题:写了一个Camel的FTP传输程序,在本地Win7和Ubuntu下运行都正常,但是在Redhat中报“File operation failed: 150 Here comes the directory listing”异常

解决方法:

首先贴出修改前的代码以及错误,如下:

代码:

                &amp;delay={{transport.fixedDelay}}

        </camel:route>
    </camel:camelContext>
</beans>

在RedHat系统下的错误:

解决方法是,在代码中增加参数“passiveMode=true”就可以了,修改后如下:
