如何解决jackson中属性的冲突getter定义

标签： json spring jackson

我有一些模型类。 

public interface Product extends Serializable {
    public Sku getDefaultSku();

   public void setDefaultSku(Sku defaultSku);
}

public interface Sku extends Serializable {
     public Boolean isTaxable();

    public Boolean getTaxable();

    public void setTaxable(Boolean taxable);
}

public interface PremiumProduct extends Product {
   public Long getProductCode();

   public void setProductCode(Long productCode);
}

无法修改产品和Sku实施。我只从产品延伸。之后，我从spring MVC控制器传输JSON对象。 我的控制器方法是

@RequestMapping(value="/productDetail", method=RequestMethod.GET)
    public @ResponseBody Product getCustomerName(@RequestParam String productUrl) throws Exception {

      Product product = catalogService.findProductByURI(productUrl);      

                return product;
    }

我有以下例外情况。

<h2>HTTP ERROR 500</h2>
<p>Problem accessing /productDetail. Reason:
<pre>    Conflicting getter definitions for property "taxable":

org.broadleafcommerce.core.catalog.domain.SkuImpl#getTaxable(0 params) vs org.broadleafcommerce.core.catalog.domain.SkuImpl#isTaxable(0 params)
(through reference chain: com.yoma.product.PremiumProductImpl["defaultSku"])</pre></p>

那么，我怎样才能从我的控制器中获取我的JSON。

5 个答案:

答案 0 :(得分：27)

您可以尝试忽略isTaxable()以解决冲突：

@JsonIgnore
public Boolean isTaxable();

答案 1 :(得分：8)

根据程序员布鲁斯的回答，我可以通过以下解决方案解决问题。

我写了MixIn类，

abstract class IgnoreSetValueMixIn {    
  @JsonIgnore public abstract Boolean getTaxable();
  @JsonIgnore public abstract Boolean isTaxable();
  @JsonManagedReference  public abstract Sku getDefaultSku();
  @JsonBackReference public abstract Product getDefaultProduct();
}

在控制器中，

@RequestMapping(value="/productDetail", method=RequestMethod.GET)
    public @ResponseBody String getCustomerName(@RequestParam String productUrl, HttpServletResponse response) throws Exception {
    ObjectMapper mapper = new ObjectMapper();

            mapper.getSerializationConfig().addMixInAnnotations(Sku.class, IgnoreSetValueMixIn.class);
            mapper.getSerializationConfig().addMixInAnnotations(SkuImpl.class, IgnoreSetValueMixIn.class);

return mapper.writeValueAsString(product);
}

答案 2 :(得分：6)

  

产品和Sku实施无法修改。

Jackson Mix-In Annotations救援！

答案 3 :(得分：1)

您也可以尝试Genson lib。要在春季启用它，您需要注册消息转换器，然后一切都应该工作。

<mvc:annotation-driven>
  <mvc:message-converters>
    <bean class="com.owlike.genson.ext.spring.GensonMessageConverter"/>
  </mvc:message-converters>
</mvc:annotation-driven>

答案 4 :(得分：0)

对于我用@JsonIgnore尝试过的类似问题 它给出了错误信息 com.fasterxml.jackson.databind.JsonMappingException：没有为类org.citi.facility.GetterMethodsObject找到序列化程序，也没有发现创建BeanSerializer的属性（为了避免异常，请禁用SerializationFeature.FAIL_ON_EMPTY_BEANS）。

我的简单代码是

class GetterMethodsObject 
{
    public int getId(){
        return 10;
    }
    @JsonIgnore
    public boolean isId(){
        return true;
    }
}
