传参 List<ApproveJobContent> contents
Optional<String> value = contents.stream().filter(ctx->"DEMAND_APPLY_EXT_ATTRBUTES".equals(ctx.getContentName()).map(ApproveJobContent::getContentValue).findAny();
value.orElse("default);
findAny() 取匹配到的第一个元素
if（）{
Optional<String> value = content.stream().filter(ctx->"OPERATOR".equal(ctx.getContentIdMapping())).map(ApproveJobContent::getContentValue).filter(val -> !"null".equal(val))
.findAny();
if(value.isPresent()){
List<String> userIds = Arrays.stream(val.orElse("").split(",")).map(String::trim).filter(StringUtils::hasText).collect(Collectors.toList());
if(!userIds.isEmpty()){
//根据List 里面的数据进行查询出来的结果
List<Map<String,String>> userList = userMapper.selectUserNameList(userIds);
Map<String,String> users = userList.stream().collect(Collector.toMap(user -> user.get("code"), user -> user.get("name")));
Map<String,String> userMap = userIds.stream().collect(Collectors.toMap(id -> id, id -> users.getOrDefault(id, id + "(null)")));
String operatorName = userMap.keySet().stream().map(userMap::get).collect(Collectors.joining(","));
sout(operatorName);
}
}
