java字符串转二维数组，二维数组转List＜List＜String＞＞,List＜List＜String＞＞转二维数组

有不对的地方欢迎提出来
使用的fastjson
废话不多说

  		String str1 = "[["1","2","3"],["12","3","4"]]";
        String str2 = "[[1,2,3],[12,3,4]]";
        String[][] parse1 = JSON.parseObject(str1, String[][].class);
        String[][] parse2 = JSON.parseObject(str2, String[][].class);

        List> lists1 = JSON.parseObject(JSON.toJSONString(parse1),
                new TypeReference>>() {
                });
        List> lists2 = JSON.parseObject(JSON.toJSONString(parse1),
                new TypeReference>>() {
                });
        String[][] parse3 = JSON.parseObject(JSON.toJSONString(lists1), String[][].class);
        String[][] parse4 = JSON.parseObject(JSON.toJSONString(lists2), String[][].class);

        System.out.println(JSON.toJSONString(parse1));
        System.out.println(JSON.toJSONString(parse2));
        System.out.println(JSON.toJSONString(lists1));
        System.out.println(JSON.toJSONString(lists2));
        System.out.println(JSON.toJSONString(parse3));
        System.out.println(JSON.toJSONString(parse4));
