示例1: MessageReader

public MessageReader(SecorConfig config, OffsetTracker offsetTracker) throws
UnknownHostException {
mConfig = config;
mOffsetTracker = offsetTracker;
mConsumerConnector = Consumer.createJavaConsumerConnector(createConsumerConfig());
if (!mConfig.getKafkaTopicBlacklist().isEmpty() && !mConfig.getKafkaTopicFilter().isEmpty()) {
throw new RuntimeException("Topic filter and blacklist cannot be both specified.");
}

mConsumerConnector.createMessageStreamsByFilter(topicFilter);
