java - Camel Spring DSL 未按预期工作

Question

尝试使用 Java 和 Spring DSL 创建一个非常简单的路由来从 FTP 位置读取数据。

使用 Java DSL 创建的路由按预期工作。

from("{{ftp.server}}").to("file:target/download").log(
            "Downloaded file ${file:name} complete.");

选项:

ftp://x.x.x.x:21/in?username=kallada&password=kallada&passiveMode=false&localWorkDirectory=/tmp&delay=5s&move=done

但是用Spring DSL创建的路由在登录FTP服务器后就退出了。

<route id="ftpSend">
    <from uri="ftp://kallada@x.x.x.x:21/in?password=kallada&amp;passiveMode=false&amp;binary=true&amp;delay=6000&amp;localWorkDirectory=/tmp"/> 
    <to uri="file://target/download"/> 
</route>

我正在使用本地安装的 FTP 服务器 (FileZilla) 来测试此应用程序。调用使用 Spring DSL 创建的路由后，程序就退出了。请参阅随附的控制台日志。

05:06:04.402 INFO  [main][org.apache.camel.impl.converter.DefaultTypeConverter] Loaded 176 type converters
05:06:04.896 INFO  [main][org.apache.camel.spring.SpringCamelContext] StreamCaching is not in use. If using streams then its recommended to enable stream caching. See more details at http://camel.apache.org/stream-caching.html

05:06:05.174 INFO  [main][org.apache.camel.spring.SpringCamelContext] Apache Camel 2.12.0 (CamelContext: camel-1) started in 1.272 seconds

超过这个点，程序就会退出。

另请参阅 FTP 服务器控制台日志。

任何解决此问题的指示都会有所帮助。

我认为你的 main 在启动 Camel 上下文后就退出了。请查看this用于独立运行 Camel 并保持其运行。
