英文:
Set naming strategy to lower camel case for one class
问题
我的项目已经定义了一个ObjectMapper，如下所示：
final ObjectMapper mapper = new ObjectMapper();
// 其他一些设置在这里
mapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
实际上，我的项目中大多数类都使用SNAKE_CASE，一切都很顺利。现在我有一个类，下游以小驼峰命名返回。我尝试在我的类上使用@JsonNaming(PropertyNamingStrategy.LowerCamelCaseStrategy)。如果存在这样的策略，那将会起作用，但似乎在PropertyNamingStrategy内部没有类似的选项。
我发现与小驼峰命名有关的只有常量PropertyNamingStrategy.LOWER_CAMEL_CASE，但似乎只在顶部的代码段中使用，我绝对不想在这里覆盖项目设置，因为几乎所有的类都使用蛇形命名法。
当然，我可以在类中的每个属性上添加@JsonProperty('propertyInLowerCamelCase')，但属性有相当多，这似乎不应该是必需的。
英文:
My project already has an ObjectMapper defined, as follows
final ObjectMapper mapper = new ObjectMapper();
// some other settings here
mapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
Most classes in my project in fact use SNAKE_CASE, and everything's peachy. Now I have a class that the downstream returns in lower camel case. I tried using @JsonNaming(PropertyNamingStrategy.LowerCamelCaseStrategy) on my class. If it existed that'd work, but nothing like that seems to exist inside PropertyNamingStrategy.
All I find referencing lower camel case is the constant PropertyNamingStrategy.LOWER_CAMEL_CASE which is only used like in the top snippet it seems, and I definitely don't want to override the project settings here, since almost all classes use snake case.
Of course, I could slap a @JsonProperty('propertyInLowerCamelCase') on every property in the class, but there's quite a few, and that seems like it shouldn't be necessary.

要强制使用 lowerCamelCase，您可以使用以下注解：
@JsonNaming(PropertyNamingStrategy::class)
这将强制使用默认命名策略（lowerCamelCase），并覆盖全局配置的命名策略。
英文:
To enforce lowerCamelCase, you can use the annotation
@JsonNaming(PropertyNamingStrategy::class)
This enforces the default naming strategy (lowerCamelCase) and overrides a globally configured naming strategy.
