Apache骆驼在传递Xml作为有效载荷并尝试将其封送给json时出错

Question

我正在使用POSTMan来测试我的API，我试图通过POSTMAN将xml（类型：application / xml）传递给我的其余api端点。我想阅读此xml，然后将相应的信息存储在数据库中。

我试图首先通过骆驼将xml转换为json，然后读取数据并将其插入。我已经正确定义了路由（我认为是这样），但是我总是遇到以下错误：

"{ \"status\": 400, \"message\": \"an error occurred: com.fasterxml.jackson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: java.io.ByteArrayInputStream@18eaa21b; line: 1, column: 2]\" }“

我要发送的xml是：

我已经在线验证了xml，并且xml中没有错误。我还在骆驼中为端点定义了路由：

rest("/readXml")
        .consumes(MediaType.APPLICATION_XML)
        .post()
        //.outType(String.class)
                .to("direct:readxml");

        from("direct:readxml").streamCaching()
                .process(readAndInsertXml)
                 .marshal().xmljson() 

                 .setHeader(Exchange.HTTP_METHOD, constant("POST")) 
                .setHeader(Exchange.CONTENT_TYPE, constant("application/xml"))
                .to("mock:result").end();

这是我的readandInsertXml处理器，目前为空。

@Component
public class ReadAndInsertXml implements Processor{

    @Override
    public void process(Exchange exchange) throws Exception {

        Logger logger = LoggerFactory.getLogger(this.getClass());
    /*  SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();*/
        try {
            logger.info("inside processor method of read xml");
            logger.info(exchange.getIn().getBody().toString());
/*          Document doc = (Document) exchange.getIn().getBody();
            logger.info("after storing in dom document");
            System.out.println(doc.getAttributes())*/;
            exchange.getOut().setBody("sample");

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

我已经在网上进行了多次搜索，但是找不到解决方案。谁能帮忙我在做什么错
