Java8之list<entity>获取实体的某一字段

Java8之list获取实体的某一字段
示例

List titles = titleList.stream().map(e -> e.get(ConstantUtil.TITLE)).collect(Collectors.toList());

优化:
List fieldList = mountTableVoList.stream().map(ResMountTable::getFieldName).collect(Collectors.toList());

map获取某一字符串 并转成string字符串
List fieldList = apiList.stream().map(aa->"’"+aa.get(“id”)+"’").collect(Collectors.toList());
String aaa=String.join(",", fieldList);
