You can use below approach for naming strategy :
您可以使用以下方法命名策略：
class MyBean {
private String inReply;
public void setInReplyToUserId(String s) {
inReply = s;
}
public String getInReplyToUserId() {
return inReply;
}
}
class MyNaming extends PropertyNamingStrategy {
@Override
public String nameForGetterMethod(MapperConfig<?> config,
AnnotatedMethod method, String defaultName)
{
// Replace underscore+letter with upper-case(letter)
// (left as exercise to reader!)
return convertName(defaultName);
}
}
objectMapper.setPropertyNamingStrategy(new MyNaming());
