如果Moshi中的值不匹配，如何回退到枚举

public class EnumFallbackAdapter<T extends Enum<T>> extends JsonAdapter<T> {
    private final Class<T> enumClass;

    public EnumFallbackAdapter(Class<T> enumClass) {
        this.enumClass = enumClass;
    }

    @Override
    public T fromJson(JsonReader reader) throws IOException {
        String value = reader.nextString();
        try {
            return Enum.valueOf(enumClass, value);
        } catch (IllegalArgumentException e) {
            return enumClass.getEnumConstants()[0]; // 返回默认的枚举值
        }
    }

    @Override
    public void toJson(JsonWriter writer, T value) throws IOException {
        writer.value(value.name());
    }
}

public class MyClass {
    @JsonAdapter(EnumFallbackAdapter.class)
    private MyEnum myEnum;
    
    // 其他字段和方法...
}

Moshi moshi = new Moshi.Builder()
        .add(new EnumFallbackAdapter<>(MyEnum.class))
        .build();
JsonAdapter<MyClass> adapter = moshi.adapter(MyClass.class);
MyClass myObject = adapter.fromJson(json);
