您可以扩展com.fasterxml.jackson.databind.introspect.JacksonAnnotationIntrospector类，并通过重写findSerializationPropertyOrder方法为任何您想要的类提供订单。

import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.introspect.AnnotatedClass;
import com.fasterxml.jackson.databind.introspect.JacksonAnnotationIntrospector;
import com.fasterxml.jackson.databind.json.JsonMapper;
import lombok.Data;

public class JacksonAnnotationIntrospectorApp {
    private final static JsonMapper JSON_MAPPER = JsonMapper.builder()
            .enable(SerializationFeature.INDENT_OUTPUT)
            .annotationIntrospector(new DynamicOrderJacksonAnnotationIntrospector())
            .build();

    public static void main(String[] args) throws Exception {
        var pojo = new DynamicOrderPojo();
        pojo.setA("A");
        pojo.setB(1);
        pojo.setC(3.33);

        JSON_MAPPER.writeValue(System.out, pojo);
    }
}

class DynamicOrderJacksonAnnotationIntrospector extends JacksonAnnotationIntrospector {

    @Override
    public String[] findSerializationPropertyOrder(AnnotatedClass ac) {
        if (ac.getRawType() == DynamicOrderPojo.class) {
            return new String[]{"b", "a", "c"};
        }
        return super.findSerializationPropertyOrder(ac);
    }
}

@Data
class DynamicOrderPojo {

    private String a;
    private Integer b;
    private Double c;
}

以上代码打印：

{
  "b" : 1,
  "a" : "A",
  "c" : 3.33
}
