Apache Camel只读第一行

Question

    from("file:D:\\camel\\input?recursive=true&delete=true")
            .split().tokenize("'",1)
            .process(new CustomProcessor())
            .to("file:D:\\camel\\output\\${header.foldername}");

Answer 1

感谢@Claus和@Souciance的反馈。实际上，我遇到了另一个挑战，我收到的许多文件没有'\n'或'\r'作为分隔符，因此，即使读取单个like也可能像读取整个文件一样。我使用带有分隔符的扫描器实现了解决方案，如下所示。

我的路由器定义如下

@Override
public void configure() throws Exception {
    from("file:D:\\camel\\input?recursive=true&delete=true")
            .process(new CustomProcessor())
            .recipientList(header("foldername"));

}

处理器代码是

    @Override
    public void process(Exchange exchange) throws Exception {
         File data =  exchange.getIn().getBody(File.class);
        Scanner sc = new Scanner(data,"UTF-8");
        sc.useDelimiter("'");
        String folderPath="";
        while (sc.hasNext()){
            String line = (String) sc.next();
         //business logic
           break;

       }
          sc.close();
         String destDir = "file:D:\\camel\\output\\"+folderPath;
        exchange.getIn().setHeader("foldername",destDir);

     }
