以嵌套Json格式往kafka写数据，每条消息都多一行空格

[moody1117]

json.txt:
{"name":"[:name]","age":[:age],"school":{"sch_name":"[:enum(file://names.txt)]","sch_address":"[:address]","scores":[{"class":"[:enum(Math,English)]","score":[:decimal(4,2,1)]}]}}

启动命令：
datafaker kafka node06.jstdata.com:9092 caolvtest 100 --metaj json.txt --interval 0.5 --outprint

结果：

{"name":"杨东","age":84,"school":{"sch_name":"旧大院","sch_address":"重庆市武汉县浔阳沈阳街g座 894541","scores":[{"class":"Math","score":36.84}]}}
