Google Calendar

Since Camel 2.15

Both producer and consumer are supported

The Google Calendar component provides access to Google Calendar via the Google Calendar Web APIs.

Google Calendar 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.

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-calendar</artifactId>
        <!-- use the same version as your Camel core version -->
        <version>x.x.x</version>
</dependency>

Component options

The Google Calendar component supports 14 options, which are listed below.

Name Description Default Type

applicationName (common)

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

String

clientId (common)

Client ID of the calendar application

String

configuration (common)

To use the shared configuration

GoogleCalendarConfiguration

emailAddress (common)

The emailAddress of the Google Service Account.

String

p12FileName (common)

The name of the p12 file which has the private key to use with the Google Service Account.

String

scopes (common)

Specifies the level of permissions you want a calendar application to have to a user account. You can separate multiple scopes by comma. See https://developers.google.com/google-apps/calendar/auth for more info.

https://www.googleapis.com/auth/calendar

String

user (common)

The email address of the user the application is trying to impersonate in the service account flow

String

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. 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

basicPropertyBinding (advanced)

Deprecated Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

clientFactory (advanced)

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

GoogleCalendarClientFactory

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 calendar 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

The Google Calendar endpoint is configured using URI syntax:

google-calendar:apiName/methodName

with the following path and query parameters:

Path Parameters (2 parameters):

String

Query Parameters (32 parameters):

Name Description Default Type

applicationName (common)

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

String

clientId (common)

Client ID of the calendar application

String

emailAddress (common)

The emailAddress of the Google Service Account.

String

inBody (common)

Sets the name of a parameter to be passed in the exchange In Body

String

p12FileName (common)

The name of the p12 file which has the private key to use with the Google Service Account.

https://www.googleapis.com/auth/calendar

String

user (common)

The email address of the user the application is trying to impersonate in the service account flow

String

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. 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

sendEmptyMessageWhenIdle (consumer)

If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.

false

boolean

exceptionHandler (consumer)

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange. There are 3 enums and the value can be one of: InOnly, InOut, InOptionalOut

ExchangePattern

pollStrategy (consumer)

A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.

PollingConsumerPollStrategy

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

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

int

backoffIdleThreshold (scheduler)

The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.

int

backoffMultiplier (scheduler)

To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.

int

delay (scheduler)

Milliseconds before the next poll.

500

long

greedy (scheduler)

If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.

false

boolean

initialDelay (scheduler)

Milliseconds before the first poll starts.

1000

long

repeatCount (scheduler)

Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever.

0

long

runLoggingLevel (scheduler)

The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that. There are 6 enums and the value can be one of: TRACE, DEBUG, INFO, WARN, ERROR, OFF

Spring Boot Auto-Configuration

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