How to @autowire some bean into JsonSerializer?

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
