Spring 引导 MVC - 未调用枚举的自定义转换器编号

Question

I tried converting a Number to an Enum Type with a custom implementation of a Converter<Number, MyEnum> in a Spring Boot MVC application. Unfortunately the converter isn't called. Instead spring converts the number as the ordinal number of the enum.
The converter is registered by a @Component annotation.

Is there a way to override the default converter for Number and Enum ?

Answer 1

you can reference to the built-in StringToEnumConverterFactory and write a custom converter factory, then register it.

The key is String of StringToEnumConverterFactory implements ConverterFactory<String, YourEnum> , instead of ConverterFactory<Integer, YourEnum> .

I used Integer before, but my custom converter is ignored.
