如何@autowire一些bean进入JsonSerializer？ [英] How to @autowire some bean into JsonSerializer?

问题描述

我在我的网络应用程序中使用延迟加载hibernate。

I am using lazy loading with hibernate in my web app.

我想在服务器响应的解析阶段从数据库加载一些对象

I would like to load some objects from the database at the parsing stage of the server response

@Component
public class DesignSerializer extends JsonSerializer<Design> {
@Autowired
IDesignService designService; <-- is null

}

这是完全可以理解的，因为 DesignSerializer 正在使用每个对象的new运算符进行实例化。

Which is totally understandable because DesignSerializer is being instantiated with the "new" operator for each object.

我确信有一种方法可以在创建时将bean注入该序列化程序，我只是不知道如何。

I am sure there is a way to inject my bean into that serializer when ever it is created, I just don't know how.

可以你们帮助我或者指出我正确的方向。

Can you guys help me or point me in the right direction.
