我尝试使用Jackson序列化/反序列化DynamoDB Record类。
我无法控制这个类，所以我尝试使用Jackson mixins。
我做了以下工作：

@JsonDeserialize( builder = RecordBuilderMixIn.class )
private abstract static class RecordMixIn
{
}

@JsonPOJOBuilder( withPrefix = "" )
private abstract class RecordBuilderMixIn
{
}

var mapper = new ObjectMapper()
                .addMixIn( Record.Builder.class, RecordBuilderMixIn.class )
                .addMixIn( Record.class, RecordMixIn.class );

但是当我执行mapper.readValue(json, Record.class);时，我得到了以下错误：

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Builder class `com.surecloud.jackson.RecordObjectMapper$RecordBuilderMixIn` does not have build method (name: 'build')

有什么解决办法吗？
