Question

我有一条骆驼路线，如下所示。每次运行路由时，如何设置骆驼来创建CodeRunner的新实例？

        public void configure() {
            from("activemq:queue:foo?asyncConsumer=true&concurrentConsumers=10")
                    .bean(new codeRunner(), "runCode")
                    .to("stream:out");
        }

您可以只在bean上使用scope =“ prototype”。这里有一些例子。路线：

from("timer://foo?period=30s")
            .setBody(simple("bean:test?method=getDate"))
            .log(LoggingLevel.INFO, "Body:${body}");

Bean：

<bean id="test" class="my.test.package.Test" scope="prototype"  />

代码：

public class Test {

final Timestamp date;

public Test() {
    this.date = new Timestamp(System.currentTimeMillis());
}

public Timestamp getDate() {
    return date;
}

}

输出：
