确实很棘手我能想到两个解决办法：
1.在原始构建器周围创建 Package ：

class BuilderDelegate {

    var field1 : String? = null
    var field2 : String? = null
    ...

    fun build() = AttributeValue.builder().also {
        it.field1 = field1
        it.field2 = field2
        ...
    }.build()
}

@JsonDeserialize(builder = BuilderDelegate::class)
interface AttributeValueMixin {
}

1.如果你是直接调用对象Map器，你可以尝试以下技巧：

val builder = mapper.readerForUpdating(AttributeValue.builder())
val value = builder.readValue<AttributeValue.Builder>(jsonData).build()

所以这感觉完全是垃圾，但它的工作，所以。.. ¯*（）*/¯
在我的例子中，我需要序列化/沙漠化一个Map<String, AttributeValue>，所以我使用了一种技术，将Map的JSON版本填充到一个“map”属性中，反序列化，然后提取“map”值：

import com.fasterxml.jackson.databind.ObjectMapper

// the Jackson mapper
val mapper = ObjectMapper()
    // I don't remember if this was needed, but I assume so...
    .setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY)
    // This is probably just to make the JSON smaller
    .setSerializationInclusion(JsonInclude.Include.NON_EMPTY)

// to JSON
val dynamoAttributes: Map<String, AttributeValue> = ... 
val attributesAsJson = mapper.writeValueAsString(dynamoAttributes)

// read back from JSON
val result: Map<String, AttributeValue> =
    mapper.readValue(
        """{"m":$attributesAsJson}""", // stuff the JSON into a map field
        AttributeValue.serializableBuilderClass())
    .build()
    .m() // extract the "strongly" typed map

摘要

首先是一个helper方法：

static ValueInstantiator createDefaultValueInstantiator(DeserializationConfig config, JavaType valueType, Supplier<?> creator) {
    class Instantiator extends StdValueInstantiator {
        public Instantiator(DeserializationConfig config, JavaType valueType) {
            super(config, valueType);
        }

        @Override
        public boolean canCreateUsingDefault() {
            return true;
        }

        @Override
        public Object createUsingDefault(DeserializationContext ctxt) {
            return creator.get();
        }
    }

    return new Instantiator(config, valueType);
}

然后为你的类添加ValueInstantiator：

var mapper = new ObjectMapper();
var module = new SimpleModule()
        .addValueInstantiator(
                AttributeValue.Builder.class,
                createDefaultValueInstantiator(
                        mapper.getDeserializationConfig(),
                        mapper.getTypeFactory().constructType(AttributeValue.Builder.class),
                        AttributeValue::builder
                )
        );

mapper.registerModule(module);

现在Jackson将能够示例化AttributeValue.Builder。
