Spring Conversion Service:如何将String转换为List <MyType>？

@Configuration
public class AppConfig {

    @Bean
    public ConversionService conversionService() {
        DefaultFormattingConversionService conversionService = new DefaultFormattingConversionService();
        conversionService.addConverter(new StringToMyTypeListConverter());
        return conversionService;
    }
}

public class StringToMyTypeListConverter implements Converter<String, List<MyType>> {

    @Override
    public List<MyType> convert(String source) {
        if (StringUtils.isEmpty(source)) {
            return Collections.emptyList();
        }

        String[] sourceArray = source.split(",");
        List<MyType> targetList = new ArrayList<>(sourceArray.length);

        for (String sourceElement : sourceArray) {
            MyType targetElement = new MyType();
            // 在这里进行MyType对象的属性设置，例如：
            targetElement.setProperty(sourceElement.trim());
            targetList.add(targetElement);
        }

        return targetList;
    }
}

@Service
public class MyService {

    @Autowired
    private ConversionService conversionService;

    public List<MyType> convertStringToMyTypeList(String source) {
        return conversionService.convert(source, List.class);
    }
}

@RestController
public class MyController {

    @Autowired
    private MyService myService;

    @GetMapping("/convert")
    public List<MyType> convert(@RequestParam("source") String source) {
        return myService.convertStringToMyTypeList(source);
    }
}
