问题 I'm using apache camel xml based paho routes for the subscription, publication process. While online, everything works fine. But I'm not able to receive the offline message. I have set the following., Constant Client ID Clean Session is FALSE, Both subscribed & published with QoS 2 With the standalone Program, it's getting all the offline messages. With the camel route it's not happening. 回答1: Finally, I was able to solve this one manually. Camel PAHO Client is not populating the callback

问题 I am trying to take files from different directories. For example I have following directory Structure vendors/dir1/files/heelo.txt vendors/dir2/files/hello2.txt in this there are 3 dirs: 1.vendors 2.dir1 and dir2 3.files since 2. dir1 and dir2 is different, so I have to take it dynamically. I have written following code: <routes xmlns="http://camel.apache.org/schema/spring"> <route id="com.performancebikes.Inventory1" autoStartup="false"> <from uri="b2bmbFileSystem://com.a/vendors/${file

问题 The documentation at Camel HTTP4 is quite clear that you can set the following options for the HTTP4 component: connectionRequestTimeout , connectTimeout , and socketTimeout . However, these are listed as general component options, not query options in the documentation (and are ignored if set as query options -- they just get passed onto the HTTP endpoint when called). So I'm not sure how to set them. The HTTPComponent class does not seem to have any setter methods for these options. The

问题 We have an implementation where messages are being placed on an AWS SQS queue and being consumed by Camel AWS. We are using concurrentConsumers = 1. We are logging the polling of the queue as done by org.apache.camel.component.aws.sqs.SqsConsumer . The test consists of sending a message to SQS (from a remote system) and then logging the time the message is on the queue. On the Camel end, we have trace logging on the SqsConsumer class, and we can see when the queue is polled, and when messages

问题 I am using camel to route messages to a Webservice. The Messages are like XML but without namespaces/prefixes. The problem now is that the Webservice expects the XML but with the appropriate namespaces for each element. So as an example: <a> <b>value_b</b> <c>value_c</c> </a> is what im getting in, but what needs to be sent out should look like this <a xmlns:n1="http://yadda-ns1.com" xmlns:n2="http://yadda-ns2.com"> <ns1:b>value_b</ns1:b> <ns2:c>value_c</ns2:c> </a> if it was the same

问题 I'm looking for a way to conditionally handle messages based on the aggregation of messages. I've looked into a lot of ways to do this, but it seems that Apache Camel doesn't support it. I'll explain the scenario and then the solutions I tried. Scenario: I'm trying to conditionally clean a directory. I poll from the directory every x days and fetch all the files (file://...). I route this into an aggregation, that aggregates the files into a single size (directorySize). I then check if this

问题 We are using Apache Camel Java DSL and the json-validator component to validate json requests against a json schema. The current camel version is 2.22.0, according to the camel documentation this supports JSON schema v4, v6, v7 and v2019-09 using the NetworkNT JSON Schema library. However, when I try a JSON schema draft 07, I get an error when running tests "Caused by: com.networknt.schema.JsonSchemaException: Unknown Metaschema: http://json-schema.org/draft-07/schema#".
