如何从producetemplate访问正文

Question

情况如下：

当使用推文作为正文调用对spring boot rout'/ tweet'的发布请求时，将启动一个路由：

@RequestMapping(value="/tweet", method = RequestMethod.POST)
@ResponseBody
public void storeTweet(@RequestBody TwitterBean twitterBean) {
    System.out.println("camel: " + twitterBean.getText());
    producerTemplate.sendBody("direct:storeTweet", twitterBean);
}

这有效，我可以在路线的日志中访问正文：

@Component
public class CamelRoutes extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("direct:firstRoute")
                .log("Camel body: ${body}");

        from("direct:storeTweet")
                .log("Store tweet: $(body)");
    }
}

我真正想做的是将该主体发送到其他API，就像我在此代码段中所做的那样：

public void executePostWithCamel(TwitterBean tweet) throws Exception {
        try {
            camelContext.addRoutes(new RoutesBuilder() {
                @Override
                public void configure() {
                    from("timer://runOnce?repeatCount=1")
                            .id("tweetToDB")
                            .process(exchange -> exchange.getIn().setBody(tweet))
                            .marshal().json(JsonLibrary.Jackson)
                            .setHeader(Exchange.HTTP_METHOD, constant("POST"))
                            .setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
                            .to("http4://localhost:8085/twitterAPI/tweet")
                            .process(exchange -> log.info("The response code is: {}", exchange.getIn().getHeader(Exchange.HTTP_RESPONSE_CODE)));
                }
            });
            camelContext.start();
        } finally {
            //camelContext.stop();
        }
    }

但是这次我似乎无法弄清楚如何访问我的推文。

修改

我用以下路线解决了我的问题：

from("direct:storeTweet")
                .process(exchange -> exchange.getIn().setBody(exchange.getIn().getBody()))
                .marshal().json(JsonLibrary.Jackson)
                .setHeader(Exchange.HTTP_METHOD, constant("POST"))
                .setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
                .to("http4://ptsv2.com/t/5f02k-1519979843/post")
                .log("Store tweet: ${body}");

谢谢！
