Question

大家好我想从json输出中删除方括号。

[
  {
    "author": "Mark Twain",
    "book": "The Adventures of Tom Sawyer",
    "cost": "$68",
    "id": "1"
  },
  {
    "author": "Arthur Conan Doyle",
    "book": "The Adventures of Sherlock Holmes",
    "cost": "$97",
    "id": "2"
  }
]

我使用下面的一个删除括号，如果我是正确的话得到输出

List<Book> list = new ArrayList<Book>();
list=(List<Book>)JSONArray.toList(
    JSONArray.fromObject(books.values()),
    new Object(),
    new JsonConfig()
);
return list;

添加了所需的罐子。但是我收到错误（控制台输出）
