Jackson JSON Views忽略

我想用Spring3.1的Jackson2.0.0，以便我可以使用jackson-Module-Hibernate。我已按照此处所述的步骤操作http://blog.pastelstudios.com/2012/03/12/spring-3-1-hibernate-4-jackson-module-hibernate/。所有这些似乎工作正常，但是当我尝试使用JSON视图，以便JSON只包含在视图中的字段它不起作用。Jackson JSON Views忽略

活动视图始终为空。如何使视图处于活动状态？我已经尝试了一天，没有运气......任何帮助都将不胜感激。提前致谢。

下面是相关的代码。

这里是映射器

import com.fasterxml.jackson.databind.ObjectMapper; 
import com.fasterxml.jackson.datatype.hibernate4.Hibernate4Module; 

public class HibernateAwareObjectMapper extends ObjectMapper { 

public HibernateAwareObjectMapper() { 
    Hibernate4Module hm = new Hibernate4Module(); 
    registerModule(hm); 
    hm.configure(Hibernate4Module.Feature.FORCE_LAZY_LOADING, true); 
}

}

这里是视图类

public class DiffViews { 
public static class Public { }

}

这里就是我使用视图的POJO

@JsonIdentityInfo(generator=ObjectIdGenerators.IntSequenceGenerator.class, property="@id") 
@JsonIgnoreProperties(ignoreUnknown=true) 
@Entity 
public class Premium implements java.io.Serializable { 

@JsonView(DiffViews.Public.class) 
private String sequence; 
@JsonView(DiffViews.Public.class) 

@Column(name = "SEQUENCE", nullable = false, length = 4) 
public String getSequence() { 
    return this.sequence; 
} 

public void setSequence(String sequence) { 
    this.sequence = sequence; 
} 

@Column(name = "NAME", nullable = false) 
public String getName() { 
    return this.name; 
} 

public void setName(String name) { 
    this.name = name; 
}

）

在我的春天控制器

@RequestMapping("/cartonPremium") 
public void listAll(
     @RequestParam("page") int page, @RequestParam("rows") int maxResults, 
     @RequestParam("sidx") String sortKey, @RequestParam("sord") String sortOrder, HttpServletResponse response) { 

    HibernateAwareObjectMapper mapper = new HibernateAwareObjectMapper(); 
    mapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS); 
    mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS); 
    mapper.enable(SerializationFeature.WRITE_CHAR_ARRAYS_AS_JSON_ARRAYS); 
    mapper.disable(MapperFeature.DEFAULT_VIEW_INCLUSION); 

    JqgridResponse<Premium> gridResponse = new JqgridResponse<Premium>(); 
    gridResponse.setRows(premiumList); 
    gridResponse.setRecords(""+premiumList.size()); 
    gridResponse.setTotal(""+premiumList.size()); 
    gridResponse.setPage(""+page);  

    try { 
     ObjectWriter objWriter= mapper.writerWithView(DiffViews.Public.class); 
     Class<?> xxx = mapper.getSerializationConfig().getActiveView(); 
     objWriter.writeValue(response.getOutputStream(), gridResponse); 
     //mapper.writerWithView(DiffViews.Public.class).writeValue(response.getOutputStream(), gridResponse); 
    } catch (JsonGenerationException e) { 
     e.printStackTrace(); 
    } catch (JsonMappingException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
}

我的Spring配置

<mvc:annotation-driven> 
    <mvc:message-converters>  
     <bean class="com.creata.json.MappingJackson2HttpMessageConverter">   
      <property name="objectMapper">    
       <bean class="com.creata.json.HibernateAwareObjectMapper" />   
      </property>  
     </bean> 
    </mvc:message-converters> 
</mvc:annotation-driven>

+1如何使用writerWithView和响应输出流 – oak

我终于找到我的错误...我返回我的域名POJO在一个名为JqgridResponse包装和我没有在这个包装类的字段中添加@JsonView注释。所以一切都很好，json视图不会被忽略。
