Chapter 15. Box

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.
To configure a camel-box component to use Transport Layer Security (TLS), see chapter "Configuring Transport Security for Camel Components" in "Security Guide".
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>

    box://endpoint-prefix/endpoint?[options]
Endpoint prefix can be one of:
  • collaborations
  • comments
  • events
  • files
  • folders
  • groups
  • poll-events
  • search
  • shared-comments
  • shared-files
  • shared-folders
  • shared-items
  • users

Box Component

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.
If a value is not provided for the option defaultRequest either in the endpoint URI or in a message header, it will be assumed to be null. Note that the null value will only be used if other options do not satisfy matching endpoints.
In case of Box API errors the endpoint will throw a RuntimeCamelException with a com.box.restclientv2.exceptions.BoxSDKException derived exception cause.

Consumer Endpoints:

For more information on Box events see https://developers.box.com/docs/#events and for long polling see https://developers.box.com/docs/#events-long-polling. Consumer endpoints can only use the endpoint prefix poll-events as shown in the example next. By default the consumer will split the com.box.boxjavalibv2.dao.BoxEventCollection from every long poll and create an exchange for every com.box.boxjavalibv2.dao.BoxEvent. To make the consumer return the entire collection in a single exchange, use the URI option consumer.splitResult=false.

Result Body Type

splitResult
boolean

Message header

Any of the options can be provided in a message header for producer endpoints with CamelBox. prefix.

Message body

All result message bodies utilize objects provided by the Box Java SDK. Producer endpoints can specify the option name for incoming message body in the inBody endpoint parameter.

Type Converter

The Box component also provides a Camel type converter to convert GenericFile objects from File component to a com.box.restclientv2.requestsbase.BoxFileUploadRequestObject to upload files to Box.com. The target folderId for the upload can be specified in the exchange property CamelBox.folderId. If the exchange property is not specified the value defaults to "0" for the root folder ID.

Use cases

The following route uploads new files to the user's root folder:
	from("file:...")
		.to("box://files/upload/inBody=fileUploadRequest");
The following route polls user's account for updates:
	from("box://poll-events/poll?streamPosition=-1&streamType=all&limit=100")
		.to("bean:blah");
The following route uses a producer with dynamic header options. The fileId property has the Box file id , so its assigned to the CamelBox.fileId header as follows:
	from("direct:foo")
		.setHeader("CamelBox.fileId", header("fileId"))
		.to("box://files/download")
		.to("file://...");
