问题 I have a custom Spring XD source module that uses Spring Social for Twitter and outputs Tweet objects. This is working just fine. I can log the output of the source and see the Tweet objects listed. I can change the output type of the source for that stream to application/json to see the output at JSON. This works as expected. I then created a processor module that will create a new object from that Tweet and output it. The transform message expects a GenericMessage containing a Tweet object

问题 The goal is to read data emitted over the network. On the data generation side I have an app which spews to stdout. The content of this data is a JSON string. Here's what I'm doing (on Linux Mint 17, using an BSD flavored netcat): data generation: my_app_which_outputs_json | netcat localhost 9999 In SpringXD: (with xd-singlenode ) xd:>stream create --name tcptest --definition "tcp --decoder=LF --port=9999 | file " --deploy Created and deployed new stream 'tcptest' Output: /tmp/xd/output$ cat

问题 I am trying to hit a rest api from my http-client processor module. I would like to know how can I send request header to the url I am trying to hit. Without the request header I get 500 Internal Server Error. Will mappedRequestHeaders option be useful to pass headers, can someone give an example please. Below is how my stream looks like : jms --destination= | http-client --url='''https://hostname:11210/cards/accounts?eName=John%20Smith&caFSix=426600&caLF=1234''' --httpMethod=GET | log 回答1:

问题 I am struggling this for days now. I am using SI adaptor for kafka under Spring-boot container. I have configured zookeeper and kafka on my machine. I also created console producer and consumer tested it and everything works fine(I manage to produce vis the console messages and have the console consumer to consume them).

问题 I'm looking for some advice on setting up a Spring Data Flow stream for a specific use case. My use case: I have 2 RDBMS and I need to compare the results of queries run against each. The queries should be run roughly simultaneously. Based on the result of the comparison, I should be able to send an email through a custom email sink app which I have created. I envision the stream diagram to look something like this (sorry for the paint): The problem is that SDF does not, to my knowledge,

问题 I want to filter out payload if it contains following error codes 202048 202049 200003 filter --expression=payload.contains('202048')||payload.contains('202049')||payload.contains('200003') Can i put or condition in my expression || is my or 回答1: See the SpEL language reference. Use OR (or or ). You need spaces around the or so you need to quote the whole expression; since the module is likely within a string, you will need to escape the literal quotes. For example: xd:>stream create foo -

问题 I extended AbstractByteArraySerializer and now I want to use this serializer like the rest of the available TCP serializers (LF, NULL, L1, ...). I found the profiles in tcp-encdec.xml and registered my own profile: ... <beans profile="use-custom"> <bean id="CUSTOM" class="custom.tcp.serializer.ByteArrayCustomSerializer"> <property name="maxMessageSize" value="${bufferSize}" /> </bean> </beans> ... Spring uses EncoderDecoderMixins.Encoding to convert Encoding to a specific profile.

问题 I had a terrible night trying to figure out what is going on with RabbitMQ and SpringXD, unfortunately without a success. The problem: SpringXD closes RabbitMQ connections repeatedly, or reports warnings related to the channel cache size. Fragment from the SpringXD log (during stream initialization/autowiring): 2016-05-03T07:42:43+0200 1.3.0.RELEASE WARN DeploymentsPathChildrenCache-0 listener.SimpleMessageListenerContainer - CachingConnectionFactory's channelCacheSize can not be less than
