@Override
public void process(Exchange exchange) throws Exception {
    // 因为很明确消息格式是http的，所以才使用这个类
    // 否则还是建议使用org.apache.camel.Message这个抽象接口
    HttpMessage message = (HttpMessage) exchange.getIn();
    InputStream bodyStream = (InputStream) message.getBody();
    String inputContext = this.analysisMessage(bodyStream);
    bodyStream.close();

    // 存入到 exchange的 out区域
    if (exchange.getPattern() == ExchangePattern.InOut) {
        Message outMessage = exchange.getOut();
        outMessage.setBody(inputContext + " || out");
    }
}
