        @Override
        public void configure() throws Exception {
            from("file://target/enrich?move=.done").process(new Processor() {

                    name = FileUtil.stripExt(name) + ".dat";
                    // use a consumer template to get the data file
                    Exchange data = null;
                    ConsumerTemplate con = exchange.getContext().createConsumerTemplate();

                        data = con.receive("file://target/enrichdata?move=.done&fileName=" + name, 5000);
                    } finally {
                        // stop the consumer as it does not need to poll for files anymore
                        con.stop();
                    }
                    // if we found the data file then process it by sending it to the direct:data endpoint

    template.setMaximumCacheSize(500);
    template.start();
    assertEquals("Size should be 0", 0, template.getCurrentCacheSize());
    // test that we cache at most 500 consumers to avoid it eating to much memory
    for (int i = 0; i < 503; i++) {
        Endpoint e = context.getEndpoint("direct:queue:" + i);
        template.receiveNoWait(e);
    }
    // the eviction is async so force cleanup
    template.cleanUp();
    assertEquals("Size should be 500", 500, template.getCurrentCacheSize());
    template.stop();
    // should be 0
    assertEquals("Size should be 0", 0, template.getCurrentCacheSize());
}

Example 3 with ConsumerTemplate
