相关疑难解决方法(0)

我正在使用Spring Boot(1.2.1),其方式与构建RESTful Web服务教程的方式类似:

@RestController
public class EventController {

    @RequestMapping("/events/all")
    EventList events() {
        return proxyService.getAllEvents();
    }

}

所以上面,Spring MVC暗中使用Jackson将我的EventList对象序列化为JSON.

但我想对JSON格式进行一些简单的自定义,例如:

setSerializationInclusion(JsonInclude.Include.NON_NULL)

问题是,自定义隐式JSON映射器的最简单方法是什么？

我在这篇博客文章中尝试了这种方法,创建了一个CustomObjectMapper等等,但是第3步"在Spring上下文中注册类"失败了:

org.springframework.beans.factory.BeanCreationException: 
  Error creating bean with name 'jacksonFix': Injection of autowired dependencies failed; 
  nested exception is org.springframework.beans.factory.BeanCreationException: 
  Could not autowire method: public void com.acme.project.JacksonFix.setAnnotationMethodHandlerAdapter(org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter); 
  nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
  No qualifying bean of type [org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter]   
  found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. …

请帮忙!我正在尝试使用jackson kotlin模块从JSON生成对象.这是json来源:
