问题描述
我使用将我得到的JSON数据转换为Java对象。它在我所有的测试中都能很好地工作。
问题是，我们的真实对象有一些名为is_online的属性。 GSON只会映射它们，如果它们命名完全相同，那么让GSON将名称转换为Java驼峰案例isOnline会很好。
I'm using GSON to convert JSON data I get to a Java object. It works pretty well in all my tests.The problem is that our real objects have some properties named like is_online. GSON only maps them if they are named totally equal, it would be nice to have GSON convert the names to Java camel case isOnline.
看起来，创建JSON数据，骆驼大小写在JSON中被转换为下划线分隔的单词。但我无法找到一种方法来指定这种方式。
It seems this is possible while creating the JSON data, camel case is converted to underscore separated words in JSON. But I can't find a way to specify this the other way round.
推荐答案
我发现以下设置完美工作阅读带有下划线属性的json，并在我的模型中使用camelcasing。
I have found the following setting works perfect when reading json with underscored attributes and using camelcasing in my models.
Gson gson = new GsonBuilder()
.setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
.create()
