将 dict 的 dict 转换为 json

Question

I am trying to convert a dict of dict to json in order to read it with java (jsonLib java). The problem here is that I have a big Json file (130 mb) and it seems that all the date is in only one line. so I have a java out of memory exception when I try to read the file ( I read it with BufferedReader from java.io)

here is the code for dumping the json file:

    import json
    instance ={}
    instance['key1']= [a,b]
    instance['key2'] = dict of dict of dict
    instance['key3'] = dict
    instance['key4'] = dict of dict of dict 
    instance['key5'] = dict of dict

    json.dump(instance,outputFile)

So how can I organize the json file in order to parse it as simple as possible in java. Thanks for your help

Answer 1

You could break up the JSON payload into multiple files, perhaps one for each dict.

Answer 2

You should look into this http://jackson.codehaus.org/ and this http://outerthought.org/blog/415-ot.html
