我正在尝试将以下字符串转换为HashMap，因为它具有键值对：
0,2343:1,ORDER:4,Name:5,:6,:7,London:8,null:9,postcode:10,Field 1:11,Fake Place:13,:14,:15,:16,null:17,postcode:18,0208 1192000:20,Field 1:23,1:24,19700101:25,ORDNO90654:38,Fake Company:50,GB:68,null:69,0:70,1:75,KGS:21,0:79,null null GBR null null:80,GB:1222,null:21-2,0:79-2,null null GBR null null:80-2,GB:1222-2,null:112,0:116,0:119,10200:190,N:99,:
我正在使用Google的Guava库在称为
FlightProcessorTest的单元测试中执行此操作：Map<String, String> messageMap = Splitter.on(",")
.withKeyValueSeparator(":")
.split(keyValueSplit);
但是，出现以下异常：
java.lang.IllegalArgumentException: Chunk [0] is not a valid entry

最佳答案
问题出在解析字符串的开头：
0,2343：1
您使用Splitter.on（“，”）。withKeyValueSeparator（“：”），因此第一个值是未知的。
我将看到更多发生故障的地方，例如：
postcode:18,0208 1192000:20,
