Box Component
Available as of Camel 2.14
The Box component provides access to all of the Box.com APIs accessible using box-java-sdk-v2. It allows producing messages to upload and download files, create, edit, and manage folders, etc. It also supports APIs that allow polling for updates to user accounts and even changes to enterprise accounts, etc.
Box.com requires the use of OAuth2.0 for all client application authentication. In order to use camel-box with your account, you'll need to create a new application within Box.com at https://app.box.com/developers/services/edit/. The Box application's client id and secret will allow access to Box APIs which require a current user. A user access token is generated and managed by the API for an end user. Alternatively the Camel application can register an implementation of com.box.boxjavalibv2.authorization.IAuthSecureStorage to provide an com.box.boxjavalibv2.dao.IAuthData OAuth token.
Maven users will need to add the following dependency to their pom.xml for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-box</artifactId> <version>${camel-version}</version> </dependency>

BoxComponent
The Box Component can be configured with the options below. These options can be provided using the component's bean property configuration
of type org.apache.camel.component.box.BoxConfiguration
. These options can also be specified in the endpoint URI.
Option | Type | Description |
---|---|---|
authSecureStorage | com.box.boxjavalibv2.authorization.IAuthSecureStorage | OAuth Secure Storage callback, can be used to provide and or save OAuth tokens. The callback may return null on first call to allow the component to login and authorize application and obtain an OAuth token, which can then be saved in the secure storage. For the component to be able to create a token automatically a user password must be provided. |
boxConfig | com.box.boxjavalibv2.IBoxConfig | Custom Box SDK configuration, not required normally |
clientId | String | Box application client ID |
clientSecret | String | Box application client secret |
connectionManagerBuilder | com.box.boxjavalibv2.BoxConnectionManagerBuilder | Custom Box connection manager builder, used to override default settings like max connections for underlying HttpClient. |
httpParams | java.util.Map | Custom HTTP params for settings like proxy host |
loginTimeout | int | amount of time the component will wait for a response from Box.com, default is 30 seconds |
refreshListener | com.box.boxjavalibv2.authorization.OAuthRefreshListener | OAuth listener for token updates, if the Camel application needs to use the access token outside the route |
revokeOnShutdown | boolean | Flag to revoke OAuth refresh token on route shutdown, default false. Will require a fresh refresh token on restart using either a custom IAuthSecureStorage or automatic component login by providing a user password |
sharedLink | String | Box shared link for shared-* endpoints, can be a link for a shared comment, file or folder |
sharedPassword | String | Password associated with the shared link, MUST be provided with sharedLink |
userName | String | Box user name, MUST be provided |
userPassword | String | Box user password, MUST be provided if authSecureStorage is not set, or returns null on first call |
Producer Endpoints:
Producer endpoints can use endpoint prefixes followed by endpoint names and associated options described next. A shorthand alias can be used for some endpoints. The endpoint URI MUST contain a prefix.
Endpoint options that are not mandatory are denoted by []. When there are no mandatory options for an endpoint, one of the set of [] options MUST be provided. Producer endpoints can also use a special option inBody
that in turn should contain the name of the endpoint option whose value will be contained in the Camel Exchange In message.
Any of the endpoint options can be provided in either the endpoint URI, or dynamically in a message header. The message header name must be of the format CamelBox.<option>
. Note that the inBody
option overrides message header, i.e. the endpoint option inBody=option
would override a CamelBox.option
header.
In case of Box API errors the endpoint will throw a RuntimeCamelException with a com.box.restclientv2.exceptions.BoxSDKException cause.
Consumer Endpoints:
Any of the producer endpoints that take a reading#reading parameter can be used as a consumer endpoint. The polling consumer uses the since and until fields to get responses within the polling interval. In addition to other reading fields, an initial since value can be provided in the endpoint for the first poll.
Rather than the endpoints returning a List (or facebook4j.ResponseList) through a single route exchange, camel-facebook creates one route exchange per returned object. As an example, if "facebook://home" results in five posts, the route will be executed five times (once for each Post).

Reading Options
The reading option of type facebook4j.Reading adds support for reading parameters, which allow selecting specific fields, limits the number of results, etc. For more information see Graph API#reading - Facebook Developers.
It is also used by consumer endpoints to poll Facebook data to avoid sending duplicate messages across polls.
The reading option can be a reference or value of type facebook4j.Reading, or can be specified using the following reading options in either the endpoint URI or exchange header with CamelFacebook. prefix.
Option | Description |
---|---|
reading.fields | Field names to retrieve, in the format field1,field2,... |
reading.limit | Limit for number of items to return for list results, e.g. a limit of 10 returns items 1 through 10 |
reading.offset | Starting offset for list results, e.g. a limit of 10, and offset of 10 returns items 11 through 20 |
reading.until | A Unix timestamp or strtotime data value that points to the end of the range of time-based data |
reading.since | A Unix timestamp or strtotime data value that points to the start of the range of time-based data |
reading.locale | Retrieve localized content in a particular locale, specified as a String with the format language[,country][,variant] |
reading.with | Retrieve information about objects that have location information attached, set it to true |
reading.metadata | Use Facebook Graph API Introspection to retrieve object metadata, set it to true |
reading.filter | User's stream filter key. See Facebook stream_filter |
Message header
Any of the URI options#urioptions can be provided in a message header for producer endpoints with CamelFacebook. prefix.
Message body
All result message bodies utilize objects provided by the Facebook4J API. Producer endpoints can specify the option name for incoming message body in the inBody endpoint parameter.
For endpoints that return an array, or facebook4j.ResponseList, or java.util.List, a consumer endpoint will map every elements in the list to distinct messages.
Use cases
To create a post within your Facebook profile, send this producer a facebook4j.PostUpdate body.
from("direct:foo") .to("facebook://postFeed/inBody=postUpdate);
To poll, every 5 sec., all statuses on your home feed:
from("facebook://home?delay=5") .to("bean:blah");
Searching using a producer with dynamic options from header.
In the bar header we have the Facebook search string we want to execute in public posts, so we need to assign this value to the CamelFacebook.query header.
from("direct:foo") .setHeader("CamelFacebook.query", header("bar")) .to("facebook://posts");
