问题 I have a document with an order and a number of lines. I need to break the order into lines so I have a camel splitter set to xpath with the order line as it's value. This works fine. However, what I get going forward is an element for the order line, which is what I want, but when converting it I need information from the order element - but if I try to get the parent element via xpath following the split, this doesn't work. Does Camel create copies of the nodes returned by the xpath

问题 I am successfully using ZipSplitter() to process files inside a zip file. I would like to use parallel processing if possible, but calling parallelProcessing() results in the stream being closed prematurely. This results results in an IOException when the stream is being cached by DefaultStreamCachingStrategy . I note that when parallel processing is enabled, ZipIterator#checkNullAnswer(Message) is called which closes the ZipInputStream . Curiously, everything is dandy if I loiter on this

问题 I need to make onException, to be global over the whole route builders I have in order not to rewrite the same line for every route builder I create . The current scope for my exception handler is a camel context for specific route builder . I need to make route builder classes ,r1 and r2, to use the same onException().process. The current working onException I use : def configure { onException(classOf[CustomException]).process(exceptionProcessor). process(doExtraProcess) from(address).

问题 Iam trying to implement replay mechanisam with camel ie., i will have to retrieve all the messages already persisted and forward to appropriate camel route to reprocess.This will be triggred by quartz scheduler. I achieved the same by using below. 1) once the quartz scheduler is triggered, fwd to processor which will query db and have the message as list and set the same in camel exchange properties as list. 2) Use the camel in which LoopProcessor will set appropriate xml in the iteration in

问题 I'm running a SQL consumer to read changes from a table, which is all well and good. However, there are occasions where changes happen on mass, and then my query breaks with out of memory error, as you might expect. Unfortunately, I'm stuck on Camel 2.17.6, so the StreamList option for the SQL component isn't available. (Although according to Camel-SQL Why using StreamList seems to load all ResultSet? this doesn't work as a stream list due to Spring JDBC limitations.) So I've re-written my

问题 I am getting the exception Cannot find any routes with this RouteBuilder reference: RouteBuilderRef[routebuilderOne] when I am trying to wire the route builder based on configuration. Class file of Route Builder 1 import org.apache.camel.spring.SpringRouteBuilder; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; @Component public class RoutebuilderOne extends

问题 How Apache Camel Seda Component works? 回答1: I did not find any question in your input. Therefore I guess you ask the ultimate question about Life, the Universe and Everything. So, the answer is: 42 ;-) 回答2: Let me explain you with the below code snippet a. from("direct:startProcess") b. .process(new TestProcessor()) c. .split(method(new BaseSplitter<Integer>())) d. .parallelProcessing() e. .to("seda:checkforCorrect"); f. from("seda:checkforCorrect?concurrentConsumers=25") g. …...processing

问题 I have the following route in Camel: <route> <from uri="servlet:///user?matchOnUriPrefix=true"/> <setHeader headerName="cachename"> <simple>${header.CamelHttpPath.split("/")[1]}</simple> </setHeader> <setHeader headerName="key1"> <simple>${header.CamelHttpPath.split("/")[2]}</simple> </setHeader> <to uri="direct:put"/> </route> <route> <from uri="direct:put" /> <!-- If using version 2.8 and above set headerName to "CamelHazelcastOperationType" --> <setHeader headerName=

问题 I've got a camel route reading from a file and it's not deleting the .CamelLock file after the route finishes so I wanted to turn lock off. The documentation for Camel-File says that the attribute is "lock" yet when I do <from uri="file:///data/in/?lock=false" /> I get: Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: file:///data/in/?lock=false due to: Failed to resolve endpoint: file:///data/in/?lock=false due to: There are 1 parameters that couldn't

问题 I'm trying to create en REST endpoint with Apache Camel. I already have a REST service that return me JSON content and I want this endpoint to get it. My problem is that I don't know what's happening when my Camel route is built.. For the moment, it doesn't do anything. Here is my code : restConfiguration().component("servlet") .bindingMode(RestBindingMode.json) .dataFormatProperty("prettyPrint", "true").host("localhost") .port(9080); rest("/ContextServices/rest/contextServices/document")
