无需使用注释即可自定义序列化策略spring-data-mongodb

Question

I want to customize / configure the serialization policy of spring-data-mongodb (version 1.1.1.RELEASE) without using annotations (like @Id, @Document, @Field) because I do not have access to the domain classes.

Is this possible? If yes, what is the most efficient way to do this?

Answer 1

据我所知，为了自定义类序列化，你唯一能做的就是为每个类定义自定义转换器，这在参考文献中有描述。

Answer 2

Keep in mind to have a Read- and a WriteConverter for each of your domain classes. Missing the WriteConverter might lead to unexpected content in MongoDB which is not readable by your custom ReadConverter.

ReadConverter should be annotated with @ReadingConverter and WriteConverter should be annotated with @WritingConverter .
