如何在特定异常时停止在camel splitter上循环？“stopOnException（）”会停止每个异常的循环，但我只想停止某些特定异常的循环。如果异常是“HttpOperationFailedException”，我想停止基于响应代码的循环。例如，如果响应代码为“500”，则停止执行，如果响应代码为404，则继续执行。
这可能吗？
原始问题

from("timer:categoryRouter?delay=0")
                    .process(new Processor() {
                        @Override
                        public void process(Exchange exchange) throws Exception {
                            exchange.getIn().setBody("A,F,B,D,C");
                        }
                    })
                // tell Splitter to use the aggregation strategy which handles and ignores exceptions
                .split(body(), new MyIgnoreFailureAggregationStrategy())
                    .stopOnException()
                    // log each splitted message
                    .log("Split line ${body}")
                    // and have them translated into a quote
                    .bean(WordTranslateBean.class)
                    // and send it to a mock
                    .to("mock:split")
                .end()
                // log the outgoing aggregated message
                .log("Aggregated ${body}")
                // and send it to a mock as well
                .to("mock:result");

抛出异常的Bean：

public class WordTranslateBean {

private Map<String, String> words = new HashMap<String, String>();

public WordTranslateBean() {
    words.put("A", "Camel rocks");
    words.put("B", "Hi mom");
    words.put("C", "Yes it works");
}

public String translate(String key) throws HttpOperationFailedException {
    if (!words.containsKey(key)) {
        HttpOperationFailedException httpOperationFailedException = null;
        if(key.equals("F")) {
            httpOperationFailedException = new HttpOperationFailedException("uri",500,"Internal Server Error","location",null,"Key not a known word " + key);
        }
        else {
            httpOperationFailedException = new HttpOperationFailedException("uri",404,"Resource Not Found","location",null,"Operation not supported on word " + key);
        }
        throw httpOperationFailedException;
    }
    return words.get(key);
}

}

                        }
                    })

                .split(body(), new MyIgnoreFailureAggregationStrategy())
                    .stopOnException()
                    // log each splitted message
                    .log("Split line ${body}")
                    // and have them translated into a quote
                    .doTry()
                        .bean(WordTranslateBean.class)
                        // and send it to a mock
