mapsplitter.java

final String stringToSplit = "dave:123, john:314,, matt:989";

final Map<String, String> splitKeyValues = Splitter.on(",")
        .omitEmptyStrings()
        .trimResults()
        .withKeyValueSeparator(":")
        .split(stringToSplit);

// Map Contents: {dave=123, john=314, matt=989}
