Jackson: Property can be raw, arbitrary object or POJO












0














Let's say I use Jackson to serialize and deserialize POJOs. I have a number of classes like this:



class Foo {

    String field1;

    Bar field2;

    // ...

    Baz baz;

}


Where baz is a large JSON object that I receive from an external system. I want to use Foo in three different ways:




  1. Serialize Foo and include baz without even bothering to parse it, as if I had declared it as @JsonRawValue String baz.

  2. Pretty-print Foo and include baz just like I received it except pretty-printed, as if I had declared it as Map<String, Object> baz.

  3. Pass Foo to my business logic, with baz deserialized to a POJO, as in the code above.


One way to do this would be to declare three classes, with the baz field declared in three different ways. I could also combine 2) and 3) into a single class with @JsonAnySetter and @JsonAnyGetter to capture any properties I don't recognize.



But is there a clean way to support all the three use cases above while declaring just a single Foo class?

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

          up vote 1 down vote favorite I am using openpyxl for parsing .xlsm files, and pytest for testing. When I open a file, I get the: OpenPyxl -> UserWarning: Data Validation extension is not supported and will be removed That is not really a problem bcs. program works and I can't change the .xlsm file to fix that. But... When I run pytest with something like: def test_wrong_file_format(): assert check_excel(open_excel('file.xlsm')) == True I will get the warning i mentioned altought check_excel(open_excel('file.xlsm')) returns True and the test should suceed... Is there a nice way to tell the pytest that "It's not a bug it's a feature" and tests should pass even when they get this warning? Is there other way than using something like: with pytest.warns(UserWarning): ...
