[英]Configure objectmapper inside Custom serializer jackson?
I have a CustomSerializer for a particular field written. 我有一个CustomSerializer用于编写特定字段。 I call the custom serializer on an ObjectMapper
with certain configurations like WRAP_ROOT_VALUE
, PropertyNameStrategy
, Inclusion.NON_NULL
. 我在ObjectMapper
使用WRAP_ROOT_VALUE
, PropertyNameStrategy
, Inclusion.NON_NULL
等特定配置调用自定义序列化程序。
Now inside my custom serializer I want all these properties while serializing my custom class except one ( WRAP_ROOT_VALUE
). 现在在我的自定义序列化程序中,我希望在序列化我的自定义类时除了一个( WRAP_ROOT_VALUE
)之外所有这些属性。
public class CustomSerializer extends JsonSerializer<Object>{
@Override
public void serialize(Object obj, JsonGenerator jgen,
SerializerProvider arg2) throws IOException,
JsonProcessingException {
//.......
jgen.writeObject(obj);
//...
}
So my obj
here gets serialized with root value wrapped which I don't want. 所以我的obj
在这里被序列化了root值包装,这是我不想要的。
I cannot edit my POJO for some reason. 我出于某种原因无法编辑我的POJO。
How can I disable only a single (or some) property of Objectmapper
inside a CustomSerializer ??? 如何在CustomSerializer中Objectmapper
的单个(或某些)属性?
ObjectMapper
获取ObjectMapper
From within a custom JsonSerializer
, you can get the ObjectMapper
using: 在自定义JsonSerializer
,您可以使用以下命令获取ObjectMapper
:
ObjectMapper mapper = ((ObjectMapper) jgen.getCodec());
ObjectMapper
设置ObjectMapper
You also can define a new ObjectMapper
within your custom JsonSerializer
using: 您还可以使用以下命令在自定义JsonSerializer
定义新的ObjectMapper
:
ObjectMapper mapper = new ObjectMapper();
jgen.setCodec(mapper);
