【学习笔记】【JAVA】Map.toString()后的字符串转换回Map类型

【参考地址】：Map.toString()后字符串转换回Map

	public static void main(String[] args) {
		String str = "{src_text=小牛上传,tgt_text=Ewota eswi,from=zh,to=izz,username=1109}";
		Map<String, String> map = mapStringToMap(str);
		System.out.println(map);
		System.out.println(map.get("file_url"));
		System.out.println(map.get("src_text"));
		System.out.println(map.get("tgt_text"));
		System.out.println(map.get("from"));
		System.out.println(map.get("to"));
		System.out.println(map.get("username"));
	}

	public static Map<String, String> mapStringToMap(String str) {
		str = str.substring(1, str.length() - 1);
		String[] strs = str.split(",");
		Map<String, String> map = new HashMap<String, String>();
		for (String string : strs) {
			String key = string.split("=")[0];
			String value = string.split("=")[1];
			map.put(key, value);
		}
		return map;
	}
