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 as a type safe way of configuring endpoints.

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 Yammer component supports 15 options, which are listed below.

Name	Description	Default	Type
useJson (common)	Set to true if you want to use raw JSON rather than converting to POJOs.	false	boolean
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
delay (consumer)	Delay between polling in millis.	5000	long
limit (consumer)	Return only the specified number of messages. Works for threaded set to true and threaded set to extended.	-1	int
newerThan (consumer)	Returns messages newer than the message ID specified as a numeric string. This should be used when polling for new messages. If you’re looking at messages, and the most recent message returned is 3516, you can make a request with the parameter newerThan equals to 3516 to ensure that you do not get duplicate copies of messages already on your page.	-1	long
olderThan (consumer)	Returns messages older than the message ID specified as a numeric string. This is useful for paginating messages. For example, if you’re currently viewing 20 messages and the oldest is number 2912, you could append olderThan equals to 2912 to your request to get the 20 messages prior to those you’re seeing.	-1	long
threaded (consumer)	threaded equals to true will only return the first message in each thread. This parameter is intended for apps which display message threads collapsed. threaded equals to extended will return the thread starter messages in order of most recently active as well as the two most recent messages, as they are viewed in the default view on the Yammer web interface. Enum values: true extended		String
userId (consumer)	The user id.		String
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
configuration (advanced)	Component configuration.		YammerConfiguration
requestor (advanced)	To use a specific requester to communicate with Yammer.		ApiRequestor
accessToken (security)	Required The access token.		String
consumerKey (security)	Required The consumer key.		String
consumerSecret (security)	Required The consumer secret.		String

Description

Default

Type

useJson (common)

Set to true if you want to use raw JSON rather than converting to POJOs.

false

boolean

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

Delay between polling in millis.

5000

long

limit (consumer)

Return only the specified number of messages. Works for threaded set to true and threaded set to extended.

-1

int

newerThan (consumer)

Returns messages newer than the message ID specified as a numeric string. This should be used when polling for new messages. If you’re looking at messages, and the most recent message returned is 3516, you can make a request with the parameter newerThan equals to 3516 to ensure that you do not get duplicate copies of messages already on your page.

-1

long

olderThan (consumer)

Returns messages older than the message ID specified as a numeric string. This is useful for paginating messages. For example, if you’re currently viewing 20 messages and the oldest is number 2912, you could append olderThan equals to 2912 to your request to get the 20 messages prior to those you’re seeing.

-1

long

threaded (consumer)

threaded equals to true will only return the first message in each thread. This parameter is intended for apps which display message threads collapsed. threaded equals to extended will return the thread starter messages in order of most recently active as well as the two most recent messages, as they are viewed in the default view on the Yammer web interface.

Enum values:

String

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

Consuming messages

The Yammer component provides several endpoints for consuming messages:

URI	Description
yammer:messages?[options]	All public messages in the user’s (whose access token is being used to make the API call) Yammer network. Corresponds to "All" conversations in the Yammer web interface.
yammer:my_feed?[options]	The user’s feed, based on the selection they have made between "Following" and "Top" conversations.
yammer:algo?[options]	The algorithmic feed for the user that corresponds to "Top" conversations, which is what the vast majority of users will see in the Yammer web interface.
yammer:following?[options]	The "Following" feed which is conversations involving people, groups and topics that the user is following.
yammer:sent?[options]	All messages sent by the user.
yammer:private?[options]	Private messages received by the user.
yammer:received?[options]	All messages received by the user

URI

Description

 yammer:messages?[options]

All public messages in the user’s (whose access token is being used to make the API call) Yammer network. Corresponds to "All" conversations in the Yammer web interface.

 yammer:my_feed?[options]

The user’s feed, based on the selection they have made between "Following" and "Top" conversations.

yammer:algo?[options]

The algorithmic feed for the user that corresponds to "Top" conversations, which is what the vast majority of users will see in the Yammer web interface.

yammer:following?[options]

The "Following" feed which is conversations involving people, groups and topics that the user is following.

yammer:sent?[options]

All messages sent by the user.

yammer:private?[options]

Private messages received by the user.

yammer:received?[options]

All messages received by the user

Message format

All messages by default are converted to a POJO model provided in the org.apache.camel.component.yammer.model package. The original message coming from yammer is in JSON. For all message consuming and producing endpoints, a Messages object is returned. Take for example a route like:

from("yammer:messages?consumerKey=aConsumerKey&consumerSecret=aConsumerSecretKey&accessToken=aAccessToken")
    .to("mock:result");

and lets say the yammer server returns:

{

                ]

            }
        }
        ]

    }

Camel will marshal that into a Messages object containing 2 Message objects. As shown below there is a rich object model that makes it easy to get any information you need:

Exchange exchange = mock.getExchanges().get(0);
Messages messages = exchange.getIn().getBody(Messages.class);

assertEquals(2, messages.getMessages().size());
assertEquals("Testing yammer API...", messages.getMessages().get(0).getBody().getPlain());
assertEquals("(Principal Software Engineer) has #joined the redhat.com network. Take a moment to welcome Jonathan.", messages.getMessages().get(1).getBody().getPlain());

That said, marshaling this data into POJOs is not free so if you need you can switch back to using pure JSON by adding the useJson=false option to your URI.

Creating messages

To create a new message in the account of the current user, you can use the following URI:

yammer:messages?[options]

The current Camel message body is what will be used to set the text of the Yammer message. The response body will include the new message formatted the same way as when you consume messages (i.e. as a Messages object by default).

Take this route for instance:

from("direct:start")
    .to("yammer:messages?consumerKey=aConsumerKey&consumerSecret=aConsumerSecretKey&accessToken=aAccessToken")
    .to("mock:result");

By sending to the direct:start endpoint a "Hi from Camel!" message body:

template.sendBody("direct:start", "Hi from Camel!");

a new message will be created in the current user’s account on the server and also this new message will be returned to Camel and converted into a Messages object. Like when consuming messages you can interrogate the Messages object:

Exchange exchange = mock.getExchanges().get(0);
Messages messages = exchange.getIn().getBody(Messages.class);

assertEquals(1, messages.getMessages().size());
assertEquals("Hi from Camel!", messages.getMessages().get(0).getBody().getPlain());

Retrieving users

The Yammer component provides several endpoints for retrieving users:

URI	Description
yammer:users?[options]	Retrieve users in the current user’s Yammer network.
yammer:current?[options]	View data about the current user.

URI

Description

yammer:users?[options]

Retrieve users in the current user’s Yammer network.

yammer:current?[options]

View data about the current user.

Using an enricher

It is helpful sometimes (or maybe always in the case of users to use an enricher pattern rather than a route initiated with one of the polling consumers in camel-yammer. This is because the consumers will fire repeatedly, however often you set the delay for. If you just want to look up a user’s data, or grab a message at a point in time, it is better to call that consumer once and then get one with your route.

Lets say you have a route that at some point needs to go out and fetch user data for the current user. Rather than polling for this user over and over again, use the pollEnrich DSL method:

from("direct:start")
    .pollEnrich("yammer:current?consumerKey=aConsumerKey&consumerSecret=aConsumerSecretKey&accessToken=aAccessToken")
    .to("mock:result");

This will go out and fetch the current user’s User object and set it as the Camel message body.

Spring Boot Auto-Configuration

When using yammer 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-yammer-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 16 options, which are listed below.

Name	Description	Default	Type
camel.component.yammer.access-token	The access token.		String
camel.component.yammer.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.yammer.bridge-error-handler	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
camel.component.yammer.configuration	Component configuration. The option is a org.apache.camel.component.yammer.YammerConfiguration type.		YammerConfiguration
camel.component.yammer.consumer-key	The consumer key.		String
camel.component.yammer.consumer-secret	The consumer secret.		String
camel.component.yammer.delay	Delay between polling in millis. The option is a long type.	5000	Long
camel.component.yammer.enabled	Whether to enable auto configuration of the yammer component. This is enabled by default.		Boolean
camel.component.yammer.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.yammer.limit	Return only the specified number of messages. Works for threaded set to true and threaded set to extended.	-1	Integer
camel.component.yammer.newer-than	Returns messages newer than the message ID specified as a numeric string. This should be used when polling for new messages. If you’re looking at messages, and the most recent message returned is 3516, you can make a request with the parameter newerThan equals to 3516 to ensure that you do not get duplicate copies of messages already on your page.	-1	Long
camel.component.yammer.older-than	Returns messages older than the message ID specified as a numeric string. This is useful for paginating messages. For example, if you’re currently viewing 20 messages and the oldest is number 2912, you could append olderThan equals to 2912 to your request to get the 20 messages prior to those you’re seeing.	-1	Long
camel.component.yammer.requestor	To use a specific requester to communicate with Yammer. The option is a org.apache.camel.component.yammer.ApiRequestor type.		ApiRequestor
camel.component.yammer.threaded	threaded equals to true will only return the first message in each thread. This parameter is intended for apps which display message threads collapsed. threaded equals to extended will return the thread starter messages in order of most recently active as well as the two most recent messages, as they are viewed in the default view on the Yammer web interface.		String
camel.component.yammer.use-json	Set to true if you want to use raw JSON rather than converting to POJOs.	false	Boolean
camel.component.yammer.user-id	The user id.		String

Default

Type

camel.component.yammer.access-token

The access token.

String

camel.component.yammer.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.
