Spring Integration provides support for interacting with Twitter. With the Twitter adapters, you can both receive and send Twitter messages.
Twitter is a social networking and micro-blogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author’s profile page and delivered to the author’s subscribers who are known as followers.

Listing 22-68 below shows configuration of main Spring Integration namespace and twitter related namespace in the Spring configuration file (twitter-integration-context.xml).

For configuring twitter inbound and outbound channel adapter, we need to have TwitterTemplate bean configured as bean in the Spring configuration file as shown in Listing 22-69 below.
Listing 22-69. Configuring twitter template using constructor arguments

1 2 3 4 5 6 7 8 9 10 11 |
<bean id="twitterTemplate" class="org.springframework.social.twitter.api.impl.TwitterTemplate"> <constructor-arg value="4XzBPacJQxyBzzzH"/> <constructor-arg value="AbRxUAvyCtqQtvxFK8w5ZMtMj20KFhB6o"/> <constructor-arg value="21691649-4YZY5iJEOfz2A9qCFd9SjBRGb3HLmIm4HNE"/> <constructor-arg value="AbRxUAvyNCtqQtxFK8w5ZMtMj20KFhB6o"/> </bean> |
TwitterTemplate can also be configured in another way as shown in Listing 22-70 below in which property loader is used to load the various twitter properties from twitter.properties file shown in Listing 22-71 below.

<context:property-placeholder location="classpath:twitter.properties"/> <bean id="twitterTemplate" class="org.springframework.social.twitter.api.impl.TwitterTemplate"> <constructor-arg value="${twitter.oauth.consumerKey}"/> <constructor-arg value="${twitter.oauth.consumerSecret}"/> <constructor-arg value="${twitter.oauth.accessToken}"/> <constructor-arg value="${twitter.oauth.accessTokenSecret}"/> </bean> |

Listing 22-72 below shows configuring twitter outbound channel adapter in Spring configuration file.

Listing 22-73 below shows configuring twitter inbound channel adapter in Spring configuration file.
