Camel :: FTP is a powerful open source framework in the Java class library that is used to communicate and file transmission with the FTP server in the Java application.It provides rich functions and easy -to -use APIs, making the processing file operation simple and efficient.This article will introduce in detail how to use Camel :: FTP framework to achieve FTP file transmission.
Installation and configuration:
Before starting using Camel :: FTP framework, you need to install and configure it.The following is the installation step:
1. Add Camel to the project dependency management tool :: FTP Maven dependencies:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-ftp</artifactId>
<version>x.x.x</version>
</dependency>

Example:
The following is a simple example. Demonstrate how to use Camel :: FTP framework to download files from the FTP server and save it into the local file system:
import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
public class FtpExample {
public static void main(String[] args) throws Exception {
CamelContext context = new DefaultCamelContext();
// Set FTP connection parameters
String ftpUrl = "ftp://<username>:<password>@<hostname>:<port>/<directory>?passiveMode=true";
// Create routes
context.addRoutes(new RouteBuilder() {
public void configure() {
from(ftpUrl)
.to("file://<outputDirectory>");
}
});
// Start Camel context
context.start();
// After waiting for a while, stop Camel context
Thread.sleep(5000);
context.stop();
}
}
