apache-camel - SimpleParserException : Unknown function: property. 文件名

Question

我正在使用 Apache Camel 3.0，在解析文件时出现此错误:

    from("file:" + filePath)
            .routeId("create-ticket")
            .unmarshal(ticketCsv)
            .to("jpa:Ticket")
            .log("Created new ticket with id ${body.id}")
            .convertBodyTo(String.class)
            .setProperty("fileName", simple("${header.CamelFileAbsolutePath}"))
            .setProperty("fileContents", body())
            .to("sql:INSERT INTO DOCUMENT(document_name, document_contents) VALUES(:#${property.fileName}, :#${property.fileContents})");

异常(exception):

org.apache.camel.language.simple.types.SimpleIllegalSyntaxException: Unknown function: property.fileName at location 0 ${property.fileName}

Answer 1

${property.xxx} 在 2.x 中已弃用。使用函数的正确名称 ${exchangeProperty.xxx}。
