Попробуйте этот код:
CsvParser используется для чтения текста.Но ваш текст нуждается в некоторых изменениях перед его анализом.Итак, я сделал text processing для подгонки его в формат csv.
@Grab('com.xlson.groovycsv:groovycsv:0.2')
import com.xlson.groovycsv.CsvParser
def csv = '''col_name,data_type,comment
"brand","string",""
"tactic_name","string",""
"tactic_id","string",""
"content_description","string",""
"id","bigint",""
"me","bigint",""
"npi","bigint",""
"fname","string",""
"lname","string",""
"addr1","string",""
"addr2","string",""
"city","string",""
"state","string",""
"zip","int",""
"event","string",""
"event_date","timestamp",""
"error_flag","string",""
"error_reason","string",""
"vendor","string",""
"year","int",""
"month","int",""
"",,
"# Partition Information",,
"# col_name ","data_type ","comment "
"",,
"vendor","string",""
"year","int",""
"month","int",""**'''
def maptxt = csv.split('"# Partition Information",,')
def map1txt = maptxt[0].trim()
def map2txt = maptxt[1].trim().readLines().collect{
it=it.replace('#','')
it=it.replaceAll("\\s", "")
}.join('\n')
println getAsMap(map1txt)
println getAsMap(map2txt)
Map getAsMap (def txt)
{
Map ret = [:]
def data = new CsvParser().parse(txt)
for (each in data){
if(each.col_name) // empty keys are neglected.
ret[each.col_name]=each.data_type
}
ret
}
ваш текст пуст col_name.Этот код игнорировал эти строки.
