检索由camece端点中的Producertemplate发送的属性

问题描述 投票：1回答：1

我正在开发我正在使用apche camel的spring boot应用程序我想生成动态文件url。我正在使用sendBodyAndProperty方法从中传递body和property但我面临未知函数Id错误。

producerTemplate.sendBodyAndProperty("direct:firstRout", 
            user.toString(), "Id", 
            user.getId() + ".json");

这里Id是关键，user.getId（）是值

Route Builder代码

@Component
public class CamelComponent extends RouteBuilder{

    public static String fileName;

    @Override
    public void configure() throws Exception {      
        from("direct:firstRoute").convertBodyTo(String.class)
        .to("file:///D:/test/?fileName=${Id}"));
    }   
}

这是堆栈跟踪

org.apache.camel.RuntimeCamelException: org.apache.camel.FailedToCreateRouteException: Failed to create route route1 at: >>> To[file:///D:/test/?fileName=${Id}] <<< in route: Route(route1)[[From[direct:firstRoute]] -> [ConvertBodyTo[ja... because of Failed to resolve endpoint: file:///D:/test/?fileName=%24%7BId%7D due to: Unknown function: Id at location 0
${Id}

这应该工作。

@Component
public class CamelComponent extends RouteBuilder{

    public static String fileName;

    @Override
    public void configure() throws Exception {      
        from("direct:firstRoute").convertBodyTo(String.class)
        .to("file:///D:/test/?fileName=${exchangeProperty.Id}"));
    }   
}

您访问该酒店的方式是使用exchangeProperty。
