List＜Map＞使用map中每一个字符拼接字符串

List> list = new ArrayList<>();

Map m = new HashMap();

m.put("name", "樟树街");

Map m1 = new HashMap();

m1.put("name", "樟树街1");

Map m2 = new HashMap();

m2.put("name", "樟树街1");

list.add(m);

list.add(m2);

list.add(m1);

String s= list.stream().map(p->p.get("name")).collect(Collectors.joining(","));

  List<SysInfoItem> sysInfoItems = sysFeignClient.getInfoItemsBySetId('');
// 【启用】状态的字段名称，以读好分隔
String items = sysInfoItems.stream().map(sysInfoItem -> sysInfoItem.getItemId()).collect(Collectors.joining(","));
