我已经设置了这个驼峰上下文属性：

<camelContext xmlns="http://camel.apache.org/schema/spring"
    trace="#{config.camelTrace}" useMDCLogging="true" streamCache="true">

这是我的路线定义：

<route>
        <from uri="direct:contactTheMovieDb" />
        <to
            uri="http4://api.themoviedb.org/3/movie/550?api_key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&amp;bridgeEndpoint=true" />

        <log message="contactTheMovieDb -> ${body}" loggingLevel="DEBUG"
            logName="it.umberto" />

        <!-- <setProperty propertyName="messageAsString"> -->
        <!-- <simple>${body}</simple> -->
        <!-- </setProperty> -->

        <!-- <process ref="readBodyExchange" /> -->

        <unmarshal>
            <json library="Jackson" unmarshalTypeName="it.umberto.Bean.MappingBean.Movie" />
        </unmarshal>

        <process ref="printMovie" />


        <!-- <log message="contactTheMovieDb INDENTATO -> ${body}" -->
        <!-- loggingLevel="DEBUG" logName="it.umberto" /> -->
    </route>

    <route>
        <from uri="restlet:/getMovie" />
        <setHeader headerName="CamelHttpMethod">
            <constant>GET</constant>
        </setHeader>
        <to uri="direct:contactTheMovieDb" />
        <!-- <to uri="stream:out" /> -->
        <log message="getMovie --> ${body}" loggingLevel="DEBUG" logName="it.umberto" />
    </route>

如果我删除日志正文填充正文，但如果激活它我有 null 邮件正文

这是我的申请日志：

P.S：抱歉我的英语不好:(

Answer 1

我解决了。

添加到camelContext streamCache = true（在camel 2.0之后默认禁用）：

<camelContext xmlns="http://camel.apache.org/schema/spring"
    trace="#{config.camelTrace}" useMDCLogging="true" streamCache="true">

并在阅读后添加正文：

LOG.info("................Processor ReadBodyExchange ...........START");
    String body = exchange.getIn().getBody(String.class);
    LOG.info(" ExchangeMessage="+body);
    exchange.getIn().setBody(body);
    LOG.info("................Processor ReadBodyExchange ...........END");

此致翁

日志后的Camel消息正文为null
