我试着测试camel与kafka的集成，这里已经解释过了
下面是我的代码

public class KafkaTest {

    public static void main(String args[]) throws Exception {
        CamelContext context = new DefaultCamelContext();

        context.addRoutes(new RouteBuilder() {
            public void configure() {
                from("kafka:test?zkConnect=localhost:2181&metadataBrokerList=localhost:9092")
                .process(new Processor() {
                    @Override
                    public void process(Exchange exchange) throws Exception {
                        System.out.println(exchange.getIn().getBody());
                    }
                })
                .end();
            }
        });

        context.start();
        while (true) {

        }
    }
}

但是，我得到以下错误

Exception in thread "main" org.apache.camel.FailedToCreateRouteException: Failed to create route route1: Route(route1)[[From[kafka:test?zkConnect=localhost:2181&... because of Failed to resolve endpoint: kafka://test?amp%3BmetadataBrokerList=localhost%3A9092&zkConnect=localhost%3A2181 due to: Failed to resolve endpoint: kafka://test?amp%3BmetadataBrokerList=localhost%3A9092&zkConnect=localhost%3A2181 due to: There are 2 parameters that couldn't be set on the endpoint. Check the uri if the parameters are spelt correctly and that they are properties of the endpoint. 

Unknown parameters=[{metadataBrokerList=localhost:9092, zkConnect=localhost:2181}]

请提出可能遗漏的内容。
