I am not sure if this is a Clojure question or a Java question. I don't
know Java, so I could use whatever help folks can offer.
"primitive string" here means what I can write when I am at the terminal.
We have 2 apps, one in Clojure, one in Java. They talk to each other via
Redis. I know the Java app can read stuff out of Redis, using our
"transaction-id", if I use the terminal and open up "redis-clj" and write a
string directly from the terminal. But I have this Clojure code, which
depends on Peter Taoussanis's Carmine library:
(defn worker [document]
{:pre [(string? (:transaction-id document))]}
(let [transaction-id (:transaction-id document)
document-as-string (str "{'transaction-id' : '" transaction-id "',
'debrief' : '" (:debrief document) "'}" )
redis-connection {:pool {} :spec {:host "127.0.0.1" :port 6379 }}]
(timbre/log :trace " message we will send to NLP " document-as-string)
(carmine/wcar redis-connection (carmine/set transaction-id document))
(loop [document-in-redis (carmine/wcar redis-connection (carmine/get
transaction-id))]
(if-not (.contains (first document-in-redis) "processed")
(recur (carmine/wcar redis-connection (carmine/get transaction-id)))
(do
(carmine/wcar redis-connection (carmine/del transaction-id))
document-in-redis)))))
This line in particular, I have tried doing this several ways:
document-as-string (str "{'transaction-id' : '" transaction-id "',
'debrief' : '" (:debrief document) "'}" )
In Redis, I expect to see:
{'transaction-id' : '42e574e7-3b80-424a-b9ff-01072f1e0358', 'debrief' :
'Smeek Hallie of Withers, Smeg, Harrington and Norvig responded to our
proposal and said his company is read to move forward. The rate of $400 per
ton of shredded paper was acceptable to them, and they shred about 2 tons
of documents every month. $96,000 in potential revenue annually. I will
meet with him tomorrow and we will sign the contract.'}
But if I then launch redis-cli, I see:
127.0.0.1:6379> keys *
1) "42e574e7-3b80-424a-b9ff-01072f1e0358"
127.0.0.1:6379> get "42e574e7-3b80-424a-b9ff-01072f1e0358"

$96,000 in potential revenue annually. I will meet with him
tomorrow{\x00\"we#\x00@sign\x92\x00\xa0 contract."
I don't know what all of those extra characters are. The Java app is not
picking this item up, so I assume the Java app is not seeing this as a
string. I expected this to look the same as if I had written this at the
terminal:
{'transaction-id' : '42e574e7-3b80-424a-b9ff-01072f1e0358', 'debrief' :
'Smeek Hallie of Withers, Smeg, Harrington and Norvig responded to our
proposal and said his company is read to move forward. The rate of $400 per
ton of shredded paper was acceptable to them, and they shred about 2 tons
of documents every month. $96,000 in potential revenue annually. I will
meet with him tomorrow and we will sign the contract.'}
I assume it is easy to get a string into a format that can be understood by
both a Clojure app and a Java app. I don't care what format that is, but it
needs to be consistent.
Can anyone make suggestions about what I can do to make sure the Clojure
app and the Java app both write to Redis using a format that the other will
understand? In particular, both apps need to see the "'transaction-id".
