问题 I am using ServiceMix 4.5.3 which includes Camel 2.10.7 and I am able to make XSLT 2.0 transformations with the Saxon library using the option endpoint like this: ... to("xslt:stylesheet.xsl?transformerFactoryClass=net.sf.saxon.TransformerFactoryImpl") ...

问题 Hi, What am I trying to do ? I am currently working on an ESB project (apache-camel + spring boot 2) where i read a MySQL table with more than 100 000 000 rows. I empty this table 1 row at a time, transform the row and send it to another database. How am I doing this ? Currently I use camel-sql to read the data //edited .from(sql:SELECT * FROM mytable?outputType=StreamList&outpuClass=MyClass) .split(body()).streaming() .bean(mybean, "transform") .end() Problem : As I can't make a select * and

问题 What is the exact use of "period" and "fixedRate" together ? does it really make sense because if i specified the "period" value then anyways timer will trigger after that interval. So what is the exact use of "fixedRate" flag ? I am confused please help me out ! 回答1: You can read the javadoc api of the java.util.Timer at: http://docs.oracle.com/javase/7/docs/api/java/util/Timer.html They explain the difference between fixed rate and delayed. 来源： https://stackoverflow.com/questions/17786173

问题 I have several Camel contexts in my project and i would like to document the routes if possible in a reverse engineering fashion since we want to keep the documentation up to date related to the context. what would be the best approach? 回答1: We tend to actually design the routes up front and model them using the iconography from the EIP book. That gives us a guide to then test drive our routes. Are your routes changing really often that reverse engineering is required? We are slowly looking

问题 I am trying to implement the following functionality: Read CSV file line-by-line then for every line: Build request based on the values that the line contains Send the request to the message queue Other component needs to pick up the message, process the request and send the response to another message queue (known to producer, so the producer could pick up the response). I believe that the request-reply pattern fits the bill. I installed ActiveMQ, downloaded camel and tried to use their jms

问题 I have a general question about Apache Camel. I wasn't able to find whether the aggregator is transacted. If it is transacted, how the transactions are implemented and how fast the aggregation is? 回答1: Sending the messages into the aggregator can run in a transaction. You would need a persistent store with the aggregator to let the outgoing messages act as a transaction. See the documentation about persistence http://camel.apache.org/aggregator2 For example there is a JDBC based and HawtDB

问题 I have several bundles (A, B, and C) deployed to an OSGi container, each containing a CamelContext and some routes. I have another bundle (M) with a CamelContext with a route (for collecting monitoring data) and a InterceptStrategy bean. I would like the InterceptStrategy bean from M to automatically apply to all of the other CamelContext s in the container (i.e., those in A, B, and C), without having to modify the other bundles. Ultimately, the goal is to wiretap data from each CamelContext

问题 I'd like to process messages in a queue in parallel using a simple Processor/AsyncProcessor as a destination. The processor takes a little time per message, but each message can be handled seperately, and thus at the same time (within healthy boundaries). I'm having a hard time finding examples, especially about the xml configuration of camel routes. So far, I've defined a threadpool, route and processor: <threadPool id="smallPool" threadName="MyProcessorThread" poolSize="5" maxPoolSize="50"
