java 根据list对象中的一个属性值是否一致去重的简单做法

        List<ApprovalChainInfoData> temp = new ArrayList<>();
        approvalChainInfoData = approvalChainInfoData1.stream().filter(i -> {
            boolean isSame = temp.stream().anyMatch(j -> j.getNodeKey().equals(i.getNodeKey()) && j.getApprovalId().equals(i.getApprovalId()) && j.getStartTime().equals(i.getStartTime()) && Strings.isBlank(j.getEndTime()) && Strings.isBlank(i.getEndTime()));
            if (isSame) {
                return false;
            } else {
                temp.add(i);
                return true;
            }
        }).collect(Collectors.toList());
