Spring Data Neo4J 4.0.0 : What is the right sequence of calls to lookup by property? -


i doing simple camel case lookup on node in neo4j 4.0.0.m1:

e.g. 

userrepository.findbyuserid(string userid);

i can see in log file correct cypher query generated:

match (u:user) u.userid = {0} return u

and can run code in neo4j browser expected result of 1 node being returned. can see correct json getting generated

e.g.

21:53:39.819 [tomcat-http--37] info  o.n.o.session.request.defaultrequest - post http://localhost:7474/db/data/transaction/commit, request: {"statements":[{"statement":"match (u:user) u.userid = {0} return u","parameters":{"0":"145"},"resultdatacontents":["graph"]}]}

and can run postmaster , expected result of 1 node being returned.

however, running through code named query in graphrepository returns every node currently, believe, in neo4jsession.

here userrepository:

@repository public interface usernoderepository extends graphrepository<user> {      @query ("match (u:user) u.userid = {0} return u")     public list<user> findbyuserid(string userid);  }

running code returns ever user have ever created in neo4j.

note have changed return type list because expected behavior of 1 node being returned not happening , getting mapping exception. note there named query here because wasn't sure if problem might camel case lookup vs. named query.

this working correctly in neo4j 3.3.x

also, have traced problem neo4jsession.query() call being made neo4jsession.query in turn following:

return getresponsehandler().loadall(type, response);

this returning nodes in mappingcontext given class type. should, believe, calling neo4jsession.loadbyproperty lookup on node.

is there setting missing?

@query returning undesired results has been fixed post m1 release. use snapshot build try again?

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
