Camel-sftp disable host verification globally

问题

I use Camel DSL route definition:

@Component
public class UploadRoutesDefinition extends RouteBuilder {
  ...
  @Override
    public void configure() throws Exception {

    ```
        from(String.format("sftp://%s@%s:%d/%s?password=%s&delete=true&readLock=changed&delay=%s"
        ...

When I put file into sftp folder I see following logs:

20/03/2018 14:02:4420.03.18 14:02:44.193 [Camel (My_Service) thread #3 - seda://parsed_csv] INFO  o.a.c.c.file.remote.SftpOperations - Known host file not configured, using user known host file: /home/gradle/.ssh/known_hosts

20/03/2018 14:02:44Are you sure you want to create it?. Camel will answer no.
```

I want to disable host verification.

Looks like adding &useUserKnownHostsFile=false to the path resolves my error. But I have a lot of route definitions and I don't like to add this suffix to each URL. Can I disable this verification globally?

回答1:

You cannot configure this globally. But as its java code its easy to use Camel's property placeholder to have a global ftp url you can use as base, or in your Camel route its also just Java code, so the string formatter you do, can use a base string that has the option turned on you then use with string concat etc.
