kandi X-RAY | gson-ext Summary

gson-ext is a Java library typically used in Utilities, JSON Processing applications. gson-ext has no bugs, it has no vulnerabilities and it has low support. However gson-ext build file is not available. You can download it from GitHub.

gson-ext provides JSON to XML conversion. This is handy for such tasks as leveraging XPATH against a JSON string. Because XML is more verbose than JSON and requires elements to be wrapped in matching tags, gson-ext injects some tags into the generated XML where JSON does not. There are primarily six cases (ignoring nesting. Nesting has the same six cases):. The following examples should get you going: Atomic Value JSON: {"id":1005}. Named Root JSON: { "resource" : { "name" : "test post", "data" : "some data" } }. XML: test postsome data. Unnamed Root JSON: {"access_token":"mauth|79889m9rwet|2114798|2010-06-07T09%3a51%3a03|66cb32d9e0cf9ea2dad1f999946af951","expires":3600}. Named Array JSON: {"notifications":[{"id":1005,"subject":"foo"},{"id":1006,"subject":"bar"}]}. XML: 1005 foo 1006 bar. Unnamed Array JSON: [{"id":1005,"subject":"foo"},{"id":1006,"subject":"bar"}]. XML: 1005 foo 1006 bar. Named Array w/ Nested Unnamed Array JSON: [{"named_list":[{"a":"a_value"}, {"b":"b_value"}, {"c":"c_value"}]},{"named_root":{"foo":"bar"}},{"a":"b","c":"d"},[{"humpty":1}, {"dumpty":2}]]. XML: a_valueb_value c_value barb d 1 2. Unnamed Array w/ Nested Unnamed Array JSON: [[{"a":"a_value"}, {"b":"b_value"}, {"c":"c_value"}, [{"humpty":1}, {"dumpty":2}]], [{"humpty":3}, {"dumpty":4}]]. XML: a_valueb_value c_value 1 2 3 4. Named Heterogeneous Array w/ Nested Unnamed Array JSON: [{"named_list":[{"a":"a_value"}, [{"humpty":1}, {"dumpty":2}], {"c":"c_value"}]},{"named_root":{"foo":"bar"}},{"a":"b","c":"d"}]. XML: a_value 1 2 c_value barb d. Unnamed Array w/ Nested Named Array JSON: [{"named_list":[{"a":"a_value"}, {"nested_list":[{"humpty":1}, {"dumpty":2}]}, {"c":"c_value"}]},{"named_root":{"foo":"bar"}},{"a":"b","c":"d"}]. XML: a_value 1 2 c_value barb d.

QUESTION

Deserializing polymorphic JSON with transient variables using Gson-extras

Asked 2020-Jan-22 at 21:28

I have some polymorphic java classes which I am serializing/deserializing. I'm using RuntimeTypeAdapterFactory from Gson-extras to ensure the classes serialize and deserialize correctly with "type" field set to the name of the derived class. It's working fine.

I have some other classes which I am serializing/deserializing which have some variables with the transient modifier applied. I am using PostConstructAdapterFactory, also from Gson-extras, to add a PostConstruct method to my classes so the values of the transient variables can be re-assigned after deserialization has completed and before any of the functions in the classes are called. This is also working fine.

The challenge I have is that I have another group of classes which are polymorphic and also have transient variables where I'd like to have a PostConstruct method execute after deserialization. All of my attempts to use both the RuntimeTypeAdapterFactory and PostConstructAdapterFactory together have failed. I can register both but when I do the PostConstructAdapterFactory behaviour seems to overwrite RuntimeTypeAdapterFactory behaviour resulting in my classes no longer storing the "type" field needed for the polymorphic classes.

It seems I can have one or the other but not both. I even looked at writing a hybrid AdapterFactory class with the capabilities of both Adapter Factories but that was unsuccessful too.

I feel I might be missing something obvious here about the way these are designed. Surely it's possible to get both pieces of functionality working together for my classes? Below is a simple example to demonstrate what I am saying.

Everything is fine with type adapters and you can use them both at the same time. In your case, problem is in order in which code is executed.

GsonUtils.getGson() - creates Gson object with adapters.
gson.toJson(new DerivedClass(6), BaseClass.class) - you create DerivedClass instance which executes super constructor from BaseClass which register given class in adapter (sic!).

Try this code:

QUESTION

Use Gson RuntimeTypeAdapterFactory with lenient = true setting

Asked 2020-Jan-16 at 00:05

The API we ingest returns some malformed JSON (in particular Double.NaN is serialized to a String with "NaN"). To allow this gson always sets lenient to true and correctly serializes this back to Double.NaN.

Now, we wanted to use the RuntimeTypeAdapterFactory class from gson-extras to remove some boilerplate code. The just described behaviour does not apply here anymore, we get the message

java.lang.NumberFormatException: JSON forbids NaN and infinities: NaN

which should have been ignored because of the lenient option normally set from gson.

Consider this small example:

It is not quite a bug from gson-extras since com.google.gson.TypeAdapter class comes from core library. I would suggest to register one more TypeAdapterFactory and force lenient for all JsonReader instances:
