Question

我想将csv文件转换为xml，我想将转换后的xml文件发送到activemq中的队列..是否有任何示例代码或任何参考网站或博客请帮助查找此程序的示例代码.. < / p>

Answer 1

使用Bindy和Xstream组件。从http://workingwithqueues.blogspot.ch/2012/07/converting-csv-to-xml-with-camel-bindy.html（使用JMS端点而不是文件端点）：

DataFormat bindy = new BindyCsvDataFormat("com.package.dto");
from("file://TEST?fileName=Employee.csv")
    .unmarshal(bindy)
    .marshal()
    .xstream()
    .to("jms:queue:FOO.BAR");

要连接到JMS，请查看JMS和ActiveMQ组件。
