私は、pollStrategyが定義され、レジストリに追加されたコンシューマエンドポイントとしてftp uriを持つ標準ルートを持っています。しかし、次のエラーが表示されています：pollStrategyを使用したCamel FTPは失敗します
Caused by: java.lang.IllegalArgumentException: Could not find a suitable setter for property: pollStrategy as there isn't a setter method with same type: java.lang.String nor type conversion possible: No type converter available to convert from type: java.lang.String to the required type: org.apache.camel.spi.PollingConsumerPollStrategy with value #pollingStrategy

私はさまざまな組み合わせを試みましたが、いつもこのエラーで終わります。誰でも私が見逃しているものを見つけることができますか？私のコードは、私が見たCamel単体テストとかなり似ています。ルートは次のようになります。
import org.apache.camel.*;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultPollingConsumerPollStrategy;
import org.apache.camel.spi.PollingConsumerPollStrategy;
import org.apache.camel.util.ServiceHelper;
import org.apache.commons.lang3.StringUtils;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.CountDownLatch;
import static org.apache.camel.builder.ProcessorBuilder.setBody;
public class Test extends RouteBuilder {
final CamelContext camelContext = getContext();
final org.apache.camel.impl.SimpleRegistry registry = new org.apache.camel.impl.SimpleRegistry();
final org.apache.camel.impl.CompositeRegistry compositeRegistry = new org.apache.camel.impl.CompositeRegistry();
private final CountDownLatch latch = new CountDownLatch(1);
@Override
public void configure() throws Exception {
ExceptionBuilder.setup(this);
compositeRegistry.addRegistry(camelContext.getRegistry());
compositeRegistry.addRegistry(registry);
((org.apache.camel.impl.DefaultCamelContext) camelContext).setRegistry(compositeRegistry);
registry.put("pollingStrategy", new MyPollStrategy());
from("ftp://[email protected]/receive/in?password=1234&autoCreate=false&startingDirectoryMustExist=true&pollStrategy=#pollingStrategy&fileName=test.csv&consumer.delay=10m")
.convertBodyTo(String.class)
.log(LoggingLevel.INFO, "TEST", "${body} : ${headers}");
}
private class MyPollStrategy implements PollingConsumerPollStrategy {
int maxPolls=3;
public boolean begin(Consumer consumer, Endpoint endpoint) {
return true;
}
public void commit(Consumer consumer, Endpoint endpoint, int polledMessages) {
if (polledMessages > maxPolls) {
maxPolls = polledMessages;
}
latch.countDown();
}
public boolean rollback(Consumer consumer, Endpoint endpoint, int retryCounter, Exception cause) throws Exception {
return false;
}
}
}
注、私はすべての作品その後、URIにpollStrategy参照を削除する場合。
