How to serialize this JSON Array String using Jackson Annotations?
[{"ID":"hzQ8ll","CreationDate":"Thu, 24 Feb 2011 12:53:31 GMT","Count":6,"Name":"SOMETAG"}]
The inside is of type Tag
so I just wrote this Java class:
public class Tags {
public List <Tag>tags;
}
But I get com.sun.jersey.api.client.ClientHandlerException
:
org.codehaus.jackson.map.JsonMappingException: Can not deserialize instance of com.test.Tags out of START_ARRAY token
I am using Jersey with the JacksonJsonProvider
like this:
ClientConfig config = new DefaultClientCon开发者_高级运维fig();
config.getClasses().add(JacksonJsonProvider.class);
Then I just do a simple Jersey client call:
ClientResponse response = builder.get(ClientResponse.class);
Tags tags = response.getEntity(Tags.class);
Any ideas? Most of the time my outermost elements had a name associated to it so this is new to me. Thanks for any help
You possibly have to declare a Tag[]
instead of a List<Tag>
.
I had a similar issue with a different JSON library.
It seems to have to do with difficulties introspecting generic containers.
You have a strange usage of get().
http://jersey.java.net/nonav/apidocs/1.5/jersey/com/sun/jersey/api/client/UniformInterface.html#get%28java.lang.Class%29
Return and argument type should be the same.
Either:
ClientResponse resp = builder.get(ClientResponse.class);
or
Tag[] resp = builder.get(Tag[].class);
Anyway, it seems tha the problem is that your JSON data is an array and it is being deserialized into something that is not (Tags).
Try this directly:
Tag[] tags = response.getEntity(Tag[].class);
