Telegram Spring Boot Starter

This is a starter pom for a spring boot application with the TelegramBots Java API.

The starter is available at maven central. Just add the following dependency to your pom:

<dependency>
	<groupId>com.github.xabgesagtx</groupId>
	<artifactId>telegram-spring-boot-starter</artifactId>
	<version>0.26</version>
</dependency>

For gradle users just add this to your dependencies:

compile('com.github.xabgesagtx:telegram-spring-boot-starter:0.26')

The only thing you need to do after adding the dependency is to create a bean for a bot. E.g.:

@Component
public class Bot extends TelegramLongPollingBot {
...
} 

or for a webhook bot:

@Component
public class Bot extends TelegramWebhookBot {
... 
}

if you want to overwrite a webhook for a specific bot:

@Component
public class Bot extends CustomizableTelegramWebhookBot {
... 
}

The bot will then be registered for you automatically on startup.

Configuration

The following properties can be configured (none are mandatory):

property	description	available since
telegram.external-url	external base url for the webhook	0.15
telegram.internal-url	internal base url for the webhook	0.15
telegram.key-store	keystore for the server	0.15
telegram.key-store-password	keystore password for the server	0.15
telegram.path-to-certificate	full path for .pem public certificate keys	0.15
telegram.proxy.type	type of proxy (NO_PROXY, HTTP, SOCKS4, SOCKS5)	0.22
telegram.proxy.host	host of the proxy	0.22
telegram.proxy.port	port of the proxy	0.22
telegram.proxy.user	username for proxy authentication	0.22
telegram.proxy.password	password for proxy authentication	0.22

Webhook support

You need to configure at least telegram.external-url and telegram.internal-url for webhook support. This configuration leaves the HTTPS handling to a proxy.

If you configure telegram.key-store for your HTTPS webhook bot, you need to configure telegram.key-store-password as well.

Also, telegram.path-to-certificate will only be used, if you configure the keystore.

Proxy support

For proxy support you need to set all of the following properties:

• telegram.proxy.type
• telegram.proxy.host
• telegram.proxy.port

To enable authentication for a proxy you need to set telegram.proxy.user and telegram.proxy.password.

General

In a regular spring boot setting these properties can be set in your application.properties or application.yml.

For more information on how these configuration options work, please refer to the TelegramBots Java API.

Example

An implementation example is available too.
