Java 带分隔符的String 转 Map

//注："&"为分隔符，"="为key-value区分
String str1 = "ip=192.168.0.1&deviceKey=3FCD95&time=1586747475338&version=1.3";
Map<String, String> map = new HashMap<String, String>();
String[] text = str1.split("&"); // 转换为数组
for (String str : text) {
    String[] keyText = str.split("="); // 转换key与value的数组
    if (keyText.length < 1) {
        continue;
    }
    String key = keyText[0]; // key
    String value = keyText[1]; // value
    map.put(key, value);
}
return map;
