原因是导入json中存在Ascii码值为32（十进制）以下的控制字符，如换行、文件分隔符等，需要将其替换掉。
-
如下存在文件控制符FS，其是不可见字符，但是有些软件打开时因为其使用的编码原因会显示成一些奇怪字符。文件控制符Ascill的10进制值为28，16进制值为1C

解决： 通过正则表达式将json中的控制符（ascill编码低于32的zif）替换掉
val inputJsonData ="graph_importer/src/test/resources/proddata.json"
val outJsonData ="graph_importer/src/test/resources/outData.json"
"Content" should " valid" in{
val invalidCharReg ="""[\u0000-\u001F]+"""
val source = Source.fromFile(inputJsonData,"UTF-8");
val lineIterator = source.getLines();
val out = new PrintWriter(outJsonData)
for( line <- lineIterator ){
var old = line.mkString
old = old.replaceAll(invalidCharReg,"")
out.println(old)
}
out.close()
}
