我已将路由配置为将邮件重新发送3次到HTTP url，并在所有重新发送尝试均失败的情况下记录该消息。这按预期工作。但是，如您从日志中看到的，HttpOperationFailedException似乎仍会传播到errorHandler(deadLetterChannel("log:com.xcg.routes?level=ERROR&showAll=true&multiline=true").useOriginalMessage());。我不希望将其传播到deadLetterChannel。我只希望它由onException(HttpOperationFailedException.class)记录。这该怎么做？
**路线防御**
@Override
public void configure()
{
onException(HttpOperationFailedException.class).maximumRedeliveries(3).redeliveryDelay(1000).to("log:com.xcg.routes?level=WARN&showAll=true&multiline=true");
errorHandler(deadLetterChannel("log:com.xcg.routes?level=ERROR&showAll=true&multiline=true").useOriginalMessage());
from("file://C:/temp/orders/incoming?move=processed&moveFailed=failed")
.bean(new OrderEdiTocXml(smooksOrder))
.to("file://C:/temp/orders/incoming?move=processed&moveFailed=failed")
.convertBodyTo(String.class).
.convertBodyTo(Document.class).choice()
.when(xpath("/cXML/Response/Status/@text='OK'"))
.to("file://C:/temp/orders/valid" + "?fileName=${header.CamelFileNameOnly}.xml")
.otherwise()
.to("file://C:/temp/error?fileName=${header.CamelFileNameOnly}-failed-validation.xml");
}

最佳答案
如果要抑制该异常，则需要使用handled（true）。
onException(HttpOperationFailedException.class)
.maximumRedeliveries(3).redeliveryDelay(1000)
.handled(true)
.to("log:com.xcg.routes?level=WARN&showAll=true&multiline=true");
