java将字符串转换为映射列表

Question

我有一个字符串。我想把它转换成下面的地图列表

String esConnectionPropertiesStr = "ID1, 701, REST, 0, $PROJECT_ID),\n" +
               "ID2, 702, ES_USERNAME, 0, $PROJECT_ID),\n" +
               "ID3, 703, ES_PASSWORD, 0, $PROJECT_ID),\n" +
               "ID4, 704, ES_HOST, 0, $PROJECT_ID";

输出：

[ 
    {1=ID1, 2=701, 3= ES_USERNAME, 4= 0, 5= $PROJECT_ID}, 
    {1=ID2, 2=702, 3= ES_PASSWORD, 4= 0, 5= $PROJECT_ID},
    {1=ID3, 2=703, 3=ES_HOST, 4= 0, 5= $PROJECT_ID},
    {1=ID4, 2=704, 3= ES_PORT, 4= 0, 5=$PROJECT_ID} 
]

它是通过),然后通过逗号拆分来获得映射元素。我试着跟着哪个有用

AtomicInteger index = new AtomicInteger(0);
Arrays.stream(esConnectionPropertiesStr.split("\\),"))
        .map(e -> Arrays.stream(e.split(","))
                .collect(Collectors.toMap(n1 -> index.incrementAndGet(), s -> s)))
        .peek(i -> index.set(0))
        .collect(Collectors.toList());

有更好的方法吗
