How to solve Conflicting getter definitions for property in Hymanson
提问by Kre Toni
I have some model classes.
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);
}
Product and Sku implementations cannot be modified. I only extend from Product. After that, I transfer JSON object from spring MVC controller. My controller method is
无法修改产品和 Sku 实现。我只从产品扩展。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;
}
I got following exceptions.
我有以下例外。
<h2>HTTP ERROR 500</h2>
<p>Problem accessing /productDetail. Reason:

So, how can I get my JSON from my controller.
那么，我怎样才能从我的控制器中获取我的 JSON。
回答by Benoit Wickramarachi
You can try to ignore isTaxable()for example to solve the conflict:
您可以尝试忽略isTaxable()例如解决冲突：
@JsonIgnore
public Boolean isTaxable();

My problem is ok by folllowing solution according to the Programmer Bruce's answer.
根据程序员布鲁斯的回答，我的问题可以通过以下解决方案解决。
I wrote MixIn class,
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();
}
In controller,
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);
}
回答by Programmer Bruce
Product and Sku implementations cannot modifie.
产品和 Sku 实现无法修改。

You can also try Gensonlib. To enable it in spring you need to register the message converter and then everything should work.
你也可以试试Gensonlib。要在 spring 中启用它，您需要注册消息转换器，然后一切正常。
<mvc:annotation-driven>
<mvc:message-converters>
<bean class="com.owlike.genson.ext.spring.GensonMessageConverter"/>
</mvc:message-converters>
</mvc:annotation-driven>

For the similar problem I tried with @JsonIgnore it gave error message as com.fasterxml.Hymanson.databind.JsonMappingException: No serializer found for class org.citi.facility.GetterMethodsObject and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) ).
对于我尝试使用 @JsonIgnore 的类似问题，它给出的错误消息为 com.fasterxml.Hymanson.databind.JsonMappingException: No serializer found for class org.citi.facility.GetterMethodsObject 并且没有发现创建 BeanSerializer 的属性（为了避免异常，请禁用 SerializationFeature .FAIL_ON_EMPTY_BEANS))。
my simpel code is
我的简单代码是
class GetterMethodsObject
{
public int getId(){
return 10;
}
@JsonIgnore
public boolean isId(){
return true;
}
}
