Spring集成:带有snake case的Json转换器

@Bean
public IntegrationFlow testEventFlow(){
    return IntegrationFlows.from(TestEventSink.INPUT)
        .transform(Transformers.fromJson(TestEvent.class))
        .transform(TestEvent::getSomeId)
        .log()
        .channel("nullChannel")
        .get();
}

测试事件类为:

public class TestEvent {

  private String someId;

  public TestEvent(){}

  public TestEvent(String someId){
      this.someId = someId;
  }

  public String getSomeId(){
      return someId;
  }

  public void setSomeId(String someId){
      this.someId = someId;
  }
}

TestEventSink.INPUT 以蛇为例:

{ "some_id" : "1234" }

@JsonNaming(PropertyNamingStrategy.SnakeCaseStrategy.class) 它工作得很好,但是我不能注释类,因为它来自第三方库。

spring.jackson.property-naming-strategy=SNAKE_CASE ,但也不起作用。

@Bean
public ObjectMapper objectMapper(){
    ObjectMapper mapper = new ObjectMapper();
    mapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);
    return mapper;
}

但没用。

提前谢谢!
