Question

Ok, I figured out my original question which was a trivial naming issue, so I will repurpose this question for the actual problem.

I have a class in C#:

class Test
{
    public string Foo { get; set; }
}

When I serialize the class with System.Web.Script.Serialization.JavaScriptSerializer, I get:

{"Foo":"Bar"}

In java I have a class:

class Test
{
    private String foo;
    public String getFoo() {
        return foo;
    }

    public void setFoo(String foo) {
        this.foo = foo;
    }

I’m attempting to use GSON to parse the JSON:

Gson gson = new Gson();
Test test = gson.fromJson(getJson(), Test.class);

But I get null values.

How can I map the JSON values onto a slightly different class so I can still use best practice naming conventions in each language.

Answer 1

Gson by default uses the field names as-is, so your fields would need to be named UpTime, ComputerName, etc. From a Java naming perspective that would be blasphemous, though.

Keep your fields properly named in Java style as lower camel case and tell Gson to use FieldNamingPolicy.UPPER_CAMEL_CASE instead:

Gson gson = new GsonBuilder()
    .setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
    .create();
Statistics stats = gson.fromJson(response.getJson(), Statistics.class);

Alternatively, you could adapt the C# side to output lower camel case {"upTime" : ... } of course.
