在Apache Camel Java中通过显式TLS/SSL将FTP路由转为FTPS安全连接

Got it, let's walk through converting your existing FTP route to use FTPS with explicit TLS/SSL. Here's how to adjust your configuration properly:

Key Modifications Needed #

• Switch the endpoint protocol: Replace ftp:// with ftps:// to trigger Camel's FTPS component.
• Add explicit TLS parameters: Define the security protocol and confirm explicit mode (since implicit FTPS uses a different port/handshake flow).
• Retain existing FTP settings: Keep parameters like passiveMode, delete, delay as they're still relevant for secure file transfers.

Modified Code Example #

Here's your updated configure() method with FTPS enabled:

@Override
public void configure() throws Exception {
    DataFormat bindy = new BindyCsvDataFormat("com.fileprocessor");
    
    // FTPS endpoint with explicit TLS/SSL configuration
    from("ftps://" + ftpServer + "/" + ftpDir + "?username=" + ftpUser + "&password=" + ftpPass 
         + "&passiveMode=true&delete=true&delay=10000"
         + "&securityProtocol=TLS&implicit=false")
        .to("file:" + localDir);
    
    from("file:" + localDir + "?move=" + localDirPassed + "&moveFailed=" + localDirError)
        .unmarshal(bindy)
        .process(...); // Keep your existing processing logic here
}

Parameter Breakdown #

Let's break down the new FTPS-specific parameters:

• securityProtocol=TLS: Specifies we're using TLS for secure communication (you can use SSL instead if your server requires it, but TLS is the modern, preferred standard).
• implicit=false: Enables explicit FTPS—this means the server listens on the standard FTP port 21, and the client explicitly initiates a TLS handshake with the AUTH TLS command. Set this to true only if your server uses implicit FTPS (which listens on port 990 by default).

Handling Custom Certificates (Optional) #

If your FTPS server uses a self-signed certificate or one from a private CA, you'll need to configure a custom SslContextParameters to trust it. Here's how to add that:

// Create SSL context parameters for custom truststore
SslContextParameters sslContextParams = new SslContextParameters();
KeyStoreParameters trustStoreParams = new KeyStoreParameters();
trustStoreParams.setResource("classpath:truststore.jks"); // Path to your truststore file
trustStoreParams.setPassword("truststorePassword"); // Password for the truststore
sslContextParams.setTrustStore(trustStoreParams);

// Bind the SSL context to Camel's registry
getContext().getRegistry().bind("sslContext", sslContextParams);

// Update the FTPS endpoint to use the custom SSL context
from("ftps://" + ftpServer + "/" + ftpDir + "?username=" + ftpUser + "&password=" + ftpPass 
     + "&passiveMode=true&delete=true&delay=10000"
     + "&securityProtocol=TLS&implicit=false"
     + "&sslContextParameters=#sslContext")
    .to("file:" + localDir);

This ensures Camel trusts the server's certificate when establishing the secure connection.
