我正在创建一个从本地服务器读取文件的camel路由，添加一些标头，然后将内容写入另一个远程sftp服务器上的文件。
我动态设置的标头之一是登录最终服务器所需的用户名。但是，当连接发生时，我可以看到我设置的用户名不用于登录，而是使用文字值＆＃34; $ {in.header.senderTargetUserName}＆＃34;。该物业尚未解决。
这是代码：
@Override
public void configure() throws Exception {
from(fromWorkInDirectoryEndpoint())
.transacted()
.process(new SetCustomFileName())
.process(new SetSenderTargetUsername())
.to(targetProvideFileEndpoint());
private String targetProvideFileEndpoint() {
return "sftp://${in.header.senderTargetUserName}@{{target.sftp-core.server}}/{{target.environment.inDirectory}}?disconnect=true&privateKeyUri=/certificate/private.key&fileName=${in.header.customFileName}";
}
}
public class SetCustomFileName implements Processor {
@Override
public void process(Exchange exchange) throws Exception {
final String userId = exchange.getIn().getHeader(CAMEL_FILE_NAME, String.class).replaceAll("/" + sentFileName, "");
exchange.getIn().setHeader(CUSTOM_FILE_NAME, "a_custom_file_name.txt");
exchange.getIn().setHeader(USER_ID, userId);
}
}
public class SetSenderTargetUsername implements Processor {
@Override
public void process(Exchange exchange) throws Exception {
final String userId = exchange.getIn().getHeader(USER_ID, String.class);
User user = userService.findOne(userId);
exchange.getIn().setHeader("senderTargetUserName", user.getUserNameThatShouldBeUsedOnSftp());
}
}
我得到了这个例外：

当我在抛出异常之前在最终代码上设置断点时，我可以看到登录的用户名设置为$ {in.header.senderTargetUserName}。
正如您所看到的，camel在异常之前显示了其最新的交换。该交换的标题包含我期望的值。
有什么想法吗？
答案 0 :(得分：1)
好的，所以如果我理解你的话，由于注入了标题，你的“from”端点实际上是一个动态端点。
来自http://camel.apache.org/how-to-use-a-dynamic-uri-in-to.html：
This is not valid code
This snippet is not valid code. Read on.
.to("freemarker://templateHome/${body.templateName}.ftl")
除了使用标题和来自端点之外，这与您想要的类似。
文档说如果你使用的是低于2.16的Camel，你应该使用收件人列表。
.recipientList(simple("sftp://${in.header.senderTargetUserName}@{{target.sftp-core.server}}/{{target.environment.inDirectory}}?disconnect=true&privateKeyUri=/certificate/private.key&fileName=${in.header.customFileName}"))
http://camel.apache.org/recipient-list.html 您可以在动态收件人列表下找到示例。
注意，我还没有测试过该端点。
答案 1 :(得分：1)
使用动态而不是 plain to ，路线将开始工作：
from(fromWorkInDirectoryEndpoint())
.transacted()
.process(new SetCustomFileName())
.process(new SetSenderTargetUsername())
.toD(targetProvideFileEndpoint());
自Camel：2.16 https://camel.apache.org/message-endpoint.html起可用。
对于旧版本，按照 Souciance 的建议使用recipientList。
