依次添加如下模板

abbreviation: lambdaMapKeyOneInteger
template text:

Map<Integer, $Object$> integer$Object$Map = $list$.stream().collect(Collectors.toMap($Object$::get$field$,Function.identity()));

abbreviation: lambdaMapKeyOneLong
template text:

Map<Long, $Object$> long$Object$Map = $list$.stream().collect(Collectors.toMap($Object$::get$field$,Function.identity()));

abbreviation: lambdaMapKeyOneString
template text:

Map<String, $Object$> str$Object$Map = $list$.stream().collect(Collectors.toMap($Object$::get$field$,Function.identity()));

abbreviation: lambdaMapKeyListInteger
template text:

Map<Integer, List<$Object$>> integer$Object$ListMap = $list$.stream().collect(Collectors.groupingBy($Object$::get$field$));

abbreviation: lambdaMapKeyListLong
template text:

Map<Long, List<$Object$>> long$Object$ListMap = $list$.stream().collect(Collectors.groupingBy($Object$::get$field$));

abbreviation: lambdaMapKeyListString
template text:

Map<String, List<$Object$>> string$Object$ListMap = $list$.stream().collect(Collectors.groupingBy($Object$::get$field$));

abbreviation: lambdaIdsSplit
template text:

List<Integer> ids = Arrays.stream($ids$.split(",")).map(s -> Integer.valueOf(s.trim())).collect(Collectors.toList());

abbreviation: lambdaIdsLong
template text:

List<Long> ids = $list$.stream().map($Object$::get$field$).collect(Collectors.toList());

abbreviation: lambdaIdsInteger
template text:

List<Integer> ids = $list$.stream().map($Object$::get$field$).collect(Collectors.toList());

abbreviation: lambdaIdsString
template text:

List<String> ids = $list$.stream().map($Object$::get$field$).collect(Collectors.toList());

abbreviation: lambdaFilter
template text:

List<$Object$> $list$ = $list$.stream().filter(rs -> "a".equals(rs.get$field$)).collect(Collectors.toList());

当你在idea中输入lambda，然后按Ctrl+j ，神奇的效果出现了，开启lambda表达式编写速度double，有木有！
代码提示

回车

提示后，输入动态参数，done！
