Google Drive

Since Camel 2.14

Both producer and consumer are supported

The Google Drive component provides access to the Google Drive file storage service via the Google Drive Web APIs.

Google Drive uses the OAuth 2.0 protocol for authenticating a Google account and authorizing access to user data. Before you can use this component, you will need to create an account and generate OAuth credentials. Credentials comprise of a clientId, clientSecret, and a refreshToken. A handy resource for generating a long-lived refreshToken is the OAuth playground.

In the case of a service account, credentials comprise of a JSON-file (serviceAccountKey). You can also use delegation domain-wide authority (delegate) and one, several, or all possible Drive API (V2) Auth Scopes (scopes).

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-google-drive</artifactId>
        <!-- use the same version as your Camel core version -->
        <version>x.x.x</version>
</dependency>

URI Format

The GoogleDrive Component uses the following URI format:

google-drive://endpoint-prefix/endpoint?[options]

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

Configuring components can be done with the Component DSL, in a configuration file (application.properties|yaml), or directly with Java code.

Configuring Endpoint Options

Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders, which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse.

The following two sections lists all the options, firstly for the component followed by the endpoint.

Component Options

The Google Drive component supports 13 options, which are listed below.

Name Description Default Type

applicationName (common)

Google drive application name. Example would be camel-google-drive/1.0.

String

clientId (common)

Client ID of the drive application.

String

configuration (common)

To use the shared configuration.

GoogleDriveConfiguration

delegate (common)

Delegate for wide-domain service account.

String

scopes (common)

Specifies the level of permissions you want a drive application to have to a user account. See https://developers.google.com/drive/web/scopes for more info.

List

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

autowiredEnabled (advanced)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

boolean

clientFactory (advanced)

To use the GoogleCalendarClientFactory as factory for creating the client. Will by default use BatchGoogleDriveClientFactory.

GoogleDriveClientFactory

accessToken (security)

OAuth 2 access token. This typically expires after an hour so refreshToken is recommended for long term usage.

String

clientSecret (security)

Client secret of the drive application.

String

refreshToken (security)

OAuth 2 refresh token. Using this, the Google Calendar component can obtain a new accessToken whenever the current one expires - a necessity if the application is long-lived.

String

serviceAccountKey (security)

Service account key in json format to authenticate an application as a service account. Accept base64 adding the prefix base64:.

String

boolean

bridgeErrorHandler (consumer (advanced))

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible.

Spring Boot Auto-Configuration

When using google-drive with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-google-drive-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 14 options, which are listed below.

Name Description Default Type

camel.component.google-drive.access-token

OAuth 2 access token. This typically expires after an hour so refreshToken is recommended for long term usage.

String

camel.component.google-drive.application-name

Google drive application name. Example would be camel-google-drive/1.0.

String

camel.component.google-drive.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.google-drive.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

Boolean

camel.component.google-drive.client-factory

To use the GoogleCalendarClientFactory as factory for creating the client. Will by default use BatchGoogleDriveClientFactory. The option is a org.apache.camel.component.google.drive.GoogleDriveClientFactory type.

GoogleDriveClientFactory

camel.component.google-drive.client-id

Client ID of the drive application.

String

camel.component.google-drive.client-secret

Client secret of the drive application.

String

camel.component.google-drive.configuration

To use the shared configuration. The option is a org.apache.camel.component.google.drive.GoogleDriveConfiguration type.

GoogleDriveConfiguration

camel.component.google-drive.delegate

Delegate for wide-domain service account.

String

camel.component.google-drive.enabled

Whether to enable auto configuration of the google-drive component. This is enabled by default.

Boolean

camel.component.google-drive.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

camel.component.google-drive.refresh-token

OAuth 2 refresh token. Using this, the Google Calendar component can obtain a new accessToken whenever the current one expires - a necessity if the application is long-lived.

String

camel.component.google-drive.scopes

Specifies the level of permissions you want a drive application to have to a user account. See https://developers.google.com/drive/web/scopes for more info.

List

camel.component.google-drive.service-account-key

Service account key in json format to authenticate an application as a service account. Accept base64 adding the prefix base64:.
