如何解析FeignClient响应json中的snake case字段？

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
</dependency>

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.PropertyNamingStrategy;

// 创建自定义的ObjectMapper实例
ObjectMapper objectMapper = new ObjectMapper();

// 配置ObjectMapper来解析蛇形命名的字段
objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);

import feign.codec.Decoder;
import feign.jackson.JacksonDecoder;
import org.springframework.beans.factory.ObjectFactory;
import org.springframework.boot.autoconfigure.http.HttpMessageConverters;
import org.springframework.cloud.openfeign.support.SpringDecoder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class FeignConfiguration {

    @Bean
    public Decoder feignDecoder() {
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setPropertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE);

        HttpMessageConverters httpMessageConverters = new HttpMessageConverters(
                new JacksonDecoder(objectMapper));
        ObjectFactory<HttpMessageConverters> objectFactory = () -> httpMessageConverters;

        return new SpringDecoder(objectFactory);
    }
}

import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.context.annotation.Import;
import org.springframework.web.bind.annotation.GetMapping;

@FeignClient(name = "example", url = "http://example.com")
@Import(FeignConfiguration.class) // 引入自定义的FeignClient配置
public interface ExampleClient {

    @GetMapping("/api/example")
    ExampleResponse getExample();
}
