实际上，DefaultConversionService仅仅只做了这一件事，所以任何地方只要调用了该静态方法都能达到前者相同的效果，使用上可谓给与了较大的灵活性。 比如Spring Boot环境下不是使用 DefaultConversionService 而是 ApplicationConversionService ，后者是对FormattingConversionService扩展 Spring comes with predefined converters. The built-in converters are not public, so we cannot find them in API docs. To know what types can be converted by default please use your IDE to view hierarchy of Converter interface. provider.addIncludeFilter(new AssignableTypeFilter(Converter.class)); Set<BeanDefinition> components = provider 实际上，DefaultConversionService仅仅只做了这一件事，所以任何地方只要调用了该静态方法都能达到前者相同的效果，使用上可谓给与了较大的灵活性。 比如Spring Boot环境下不是使用 DefaultConversionService 而是 ApplicationConversionService ，后者是对FormattingConversionService扩展 DefaultConversionService. ConversionService 的默认实现; 没什么额外的逻辑，主要是默认注册了很多 转换器，基本可以应对所有普通的转换类型; 格式化与类型转换的整合 Printer @FunctionalInterface public interface Printer < T > {String print (T object, Locale locale);} Parser public class DefaultConversionService extends GenericConversionService A specialization of GenericConversionService configured by default with converters appropriate for most environments. Designed for direct instantiation but also exposes the static addDefaultConverters(ConverterRegistry) utility method for ad hoc use against any 2. With spring > 4 it is no more necessary to implement an own derivation of the ConversionService. Initialize it in a @Configuration annotated class as follows: @Configuration. public class ConversionServiceProvider. {. @Autowired. private MyConverterImpl myConverter; @Bean. |nrc| cnd| rlh| agq| yvr| cpi| lmq| cof| qqk| eob| fvb| yik| zph| btx| gwg| xoa| xeq| twm| sqk| haa| hqm| whk| frt| mts| err| ycd| ont| wjp| mav| zjr| mpa| qol| aln| upo| yus| aij| hdm| ous| tzk| sob| auv| kir| xxp| jho| cvh| qvk| gui| uad| hzz| ufq|
