20.30. 使用 bridgeErrorHandler

// to handle any IOException being thrown
onException(IOException.class)
    .handled(true)
    .log("IOException occurred due: ${exception.message}")
    .transform().simple("Error ${exception.message}")
    .to("mock:error");

// this is the file route that pickup files, notice how we bridge the consumer to use the Camel routing error handler
// the exclusiveReadLockStrategy is only configured because this is from an unit test, so we use that to simulate exceptions
from("file:target/nospace?bridgeErrorHandler=true")
    .convertBodyTo(String.class)
    .to("mock:result");
