scala – 骆驼日志错误

我使用
scala camel dsl,我需要捕获异常.

我的管道没有记录句柄中的任何内容:

  s"$ftpSource"
    .log("File is received")
    .as(classOf[String])
    .attempt{
      process(failingProcessor)
    }.handle(classOf[Exception]) apply {
      process((exchange: Exchange) => logger.error(s"Error during file reading: ${exchange.in.toString}"))
    }

如何使用scala dsl正确捕获异常?以及如何指定回滚策略?我不希望它在失败的情况下重试.

我发现的唯一一个小的可怜的例子是:
https://svn.apache.org/repos/asf/camel/trunk/components/camel-scala/src/test/scala/org/apache/camel/scala/dsl/TryCatchFinallyTest.scala

最佳答案 意见回答..

恕我直言,你应该尝试使用骆驼作为声明性语言.我总觉得’尝试……捕捉’dsl太迫切了

以下是使用更具声明性的异常处理程序的示例

handle[MyException] {
  log("handling exception")
  process((e : Exchange) => e.in = "an error occured")
}.handled

"jetty:http://localhost:9091/service" ==> {

  id ("some-error-route")
  log("processing request")
  process((e : Exchange) => e.in = e.in[String].reverse)
  process((_: Exchange) => throw new MyException("Something went wrong"))
  log("done")

}

我建议您查看优秀的书籍Camel In action以了解处理错误的不同方法.
