Example 1
@Nullable
@Override
public Object convert(@Nullable Object source, TypeDescriptor sourceType, TypeDescriptor targetType) {
	if (source == null) {
		return null;
	}
	Class<?> sourceClazz = sourceType.getType();
	AccessibleObject accessibleObject = ENUM_CACHE_MAP.computeIfAbsent(sourceClazz, EnumToStringConverter::getAnnotation);
	Class<?> targetClazz = targetType.getType();
	// 如果为null,走默认的转换
	if (accessibleObject == null) {
		if (String.class == targetClazz) {
			return ((Enum) source).name();
		}
		int ordinal = ((Enum) source).ordinal();
		return ConvertUtil.convert(ordinal, targetClazz);
	}
	try {
		return EnumToStringConverter.invoke(sourceClazz, accessibleObject, source, targetClazz);
	} catch (Exception e) {
		log.error(e.getMessage(), e);
	}
	return null;
}
 
Example 2
@Nullable
private static Object invoke(Class<?> clazz, AccessibleObject accessibleObject, Object source, Class<?> targetClazz)
	throws IllegalAccessException, InvocationTargetException {
	Object value = null;
	if (accessibleObject instanceof Field) {
		Field field = (Field) accessibleObject;
		value = field.get(source);
	} else if (accessibleObject instanceof Method) {
		Method method = (Method) accessibleObject;
		Class<?> paramType = method.getParameterTypes()[0];
		// 类型转换
		Object object = ConvertUtil.convert(source, paramType);
		value = method.invoke(clazz, object);
	}
	if (value == null) {
		return null;
	}
	return ConvertUtil.convert(value, targetClazz);
