Stream的去重

public static void main(String[] args) {
        List<Map<String, String>> list = new ArrayList<>();
        Map<String, String> map = new HashMap<>();
        Map<String, String> map1 = new HashMap<>();
        Map<String, String> map2 = new HashMap<>();
        map.put("name", "張三");
        map.put("phone", "17600000001");

        map1.put("name", "李四");
        map1.put("phone", "17600000001");

        map2.put("name", "王五");
        map2.put("phone", "17600000002");

        list.add(map);
        list.add(map1);
        list.add(map2);

        List<Map<String, String>> result = new ArrayList<>();
        for (Map<String, String> mapTemp : list) {
            boolean b = result.stream().anyMatch(p -> p.get("phone").compareTo(mapTemp.get("phone")) == 0);
            if (!b) {
                result.add(mapTemp);
            }
        }
        System.out.println(result.toString());
    }

打印結果：[{phone=17600000001, name=張三}, {phone=17600000002, name=王五}]
