### Search before asking - [x] I searched in the [issues](https://github.com/apache/fesod/issues) and found nothing similar. ### Motivation 实现枚举的通用转换，一个枚举转化器适用所有枚举（继承同一个接口，属性一样） ### Solution 参照springmvc参数转换接口，org.springframework.core.convert.converter.ConverterFactory和org.springframework.core.convert.converter.Converter ` @Configuration public class WebConfig implements WebMvcConfigurer { @Autowired private ObjectMapper objectMapper; @Override public void addFormatters(FormatterRegistry registry) { registry.addConverterFactory(new StringToIEnumConverterFactory()); } } @Slf4j public class StringToIEnumConverterFactory implements ConverterFactory<String, IEnum> { @Override public <T extends IEnum> Converter<String, T> getConverter(Class<T> targetType) { return new StringToIEnumConverter(targetType); } private class StringToIEnumConverter<T extends IEnum> implements Converter<String, T> { private final Class<T> enumType; public StringToIEnumConverter(Class<T> enumType) { this.enumType = enumType; } @Override public T convert(String source) { if (StrUtil.isBlank(source)) { return null; } T result; try { ParameterizedType parameterizedType = (ParameterizedType) enumType.getGenericInterfaces()[0]; Class actualTypeArgument = (Class) parameterizedType.getActualTypeArguments()[0]; Method getEnumByValueMethod = enumType.getMethod("getEnumByValue", actualTypeArgument); Object args = source; if (StrUtil.equals(actualTypeArgument.getName(), Integer.class.getName())) { args = Integer.valueOf(source); } result = (T) getEnumByValueMethod.invoke(null, args); } catch (Exception e) { log.error("字符串转IEnum枚举发生异常", e); return null; } return result; } } } ` ### Alternatives _No response_ ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
