Apache Camel支持嵌套路由吗？

Question

    from("file:/tmp/test?include=.*.csv").process(new Processor() {
        public void process(Exchange exchange) throws Exception {
            // set output file name
            exchange.setProperty("outputFile", exchange.getIn().getHeader(Exchange.FILE_NAME, String.class) + ".tmp." + exchange.getExchangeId());
        }
    }).onCompletion().split().tokenize("\n", 100).process(new RequestProcessor()).to("direct:response").end().process(new Processor() {
        public void process(Exchange exchange) throws Exception {
            final String outputFile = exchange.getProperty("outputFile", String.class);

            // add new rout to encrypt
            CamelContext context = new DefaultCamelContext();
            context.addRoutes(new RouteBuilder() {
                public void configure() {

            from("file:/tmp/test/output?fileName=" + outputFile).marshal().pgp(keyFileName, keyUserid).to("file:/tmp/test/output?fileName=" + outputFile + ".pgp");
                }
            });

            context.start();
            Thread.sleep(5000);
            context.stop();
        }
    });

    from("direct:response").to("file:/tmp/test/output?fileName=${header.outputFile}&fileExist=Append");

你能给我建议正确的方法来启动加密路线吗。

通常（或总是）您建议的嵌套路由可能会被绕过。也许这条简单的路线会满足你的要求：

@Override
public void configure() throws Exception {
    from("file:/tmp/test?include=.*.csv")
       .split().tokenize("\n", 100)
       .setProperty("outputFile", simple("${header.CamelFileName}.${exchangeId}.pgp"))
       .log("The splitted body will be PGP encoded & written to file ${property.outputFile}")
       .marshal().pgp("keyFileName", "keyUserid")
       .to("file:/tmp/test/output?fileName=${property.outputFile}");
    }
}

不会写入任何临时文件，但拆分的内容会直接在内存中加密。

编辑：

@Override
public void configure() throws Exception {
    from("file:/tmp/test?include=.*.csv")
       .setProperty("outputFile", simple("${header.CamelFileName}.${exchangeId}.pgp"))
       .log("The body will be PGP encoded & written to file ${property.outputFile}")
       .marshal().pgp("keyFileName", "keyUserid")
       .to("file:/tmp/test/output?fileName=${property.outputFile}");
    }
}
