String attendanceid = s.split("=")[1]

This line of code is extracting the value of the attendance ID from a string "s" that is in the format "key=value".

The "split" method splits the string into an array of two strings, using the "=" character as the separator. The second element of the array (index 1), which contains the value of the attendance ID, is then assigned to the variable "attendanceid".

');List<Map<String, String>> connectParamMapList = new ArrayList<>();

for (String s : split01) {

String[] split02 = StringUtils.split(s, ',');

Map<String, String> connectParamMap = new HashMap<>();

for (String s1 : split02) {

String[] split03 = StringUtils.split(s1, '=');

connectParamMap.put(split03[0], split03[1]);

}

connectParamMapList.add(connectParamMap);

}

return connectParamMapList;

}

这段代码的作用是什么？
