如何使用BeanSerializerModifier的changeProperties添加新属性？

import com.fasterxml.jackson.databind.BeanDescription;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializationConfig;
import com.fasterxml.jackson.databind.ser.BeanPropertyWriter;
import com.fasterxml.jackson.databind.ser.BeanSerializerModifier;

import java.util.List;

public class CustomBeanSerializerModifier extends BeanSerializerModifier {

    @Override
    public List<BeanPropertyWriter> changeProperties(SerializationConfig config, BeanDescription beanDesc, List<BeanPropertyWriter> beanProperties) {
        List<BeanPropertyWriter> newBeanProperties = super.changeProperties(config, beanDesc, beanProperties);

        // 创建新的属性对象
        BeanPropertyWriter newProperty = new BeanPropertyWriter("newProperty", null, null, null, null, null, null, null, false, null);

        // 将新的属性对象添加到新的属性列表中
        newBeanProperties.add(newProperty);

        return newBeanProperties;
    }
}

@Configuration
public class JacksonConfig {

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper objectMapper = new ObjectMapper();
        SimpleModule module = new SimpleModule();
        module.setSerializerModifier(new CustomBeanSerializerModifier());
        objectMapper.registerModule(module);
        return objectMapper;
    }
}
