如何@autowire 一些 bean 到 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和休眠.

我想在服务器响应的解析阶段从数据库加载一些对象

<块引用>

@Component公共类 DesignSerializer 扩展了 JsonSerializer<Design>{@自动连线IDesignService 设计服务；<-- 为空

}

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.

我确定有一种方法可以在创建 bean 时将其注入该序列化程序，但我不知道如何操作.

你们能帮我或给我指明正确的方向吗.

解决方案

解决方案是 SpringBeanAutowiringSupport 如果您使用的是 Spring Framework 2.5+.

public class DesignSerializer 扩展 JsonSerializer{@自动连线IDesignService 设计服务；}公共 DesignSerializer(){SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);}...}

希望对你有帮助

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

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

}

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

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.

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

解决方案

Solution is SpringBeanAutowiringSupport if you are using Spring Framework 2.5+.

public class DesignSerializer extends JsonSerializer<Design> {

    @Autowired
        IDesignService designService;
    }

    public DesignSerializer(){
        SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);    
    }

...

}

I Hope that help you
