使用双引号的json模式到pojo错误

Question

我正在尝试使用http://www.jsonschema2pojo.org/将JSON响应中提到的部分从预测api转换为POJO。当我尝试将其转换为pojo时，错误显示

There's a problem: Unexpected character ('l' (code 108)): was expecting double-quote to start field name (line 2, column 2)

现在我看到我需要在每个json响应的关键参数上使用双引号。所以我手动输入双引号，然后我得到了pojo类。所以我的问题是每次都必须这样做并对每一个键应用双引号？我还缺少其他任何技巧吗？
