Spring Java配置-如何创建枚举到bean-引用的映射

您可能想要这样的东西：

@Configurationpublic class MyConfiguration {    @Bean public Map<ColourEnum, ColourHandler> colourHandlers() {        Map<ColourEnum, ColourHandler> map = new EnumMap<>();        map.put(WHITE, whiteHandler());        // etc        return map;    }    @Bean public ColourHandler whiteHandler() {        return new WhiteHandler();    }}

如果需要将处理程序保持为

@Component

@Configurationpublic class MyConfiguration {    @Autowired private WhiteColourHandler whiteColourHandler;    @Bean public Map<ColourEnum, ColourHandler> colourHandlers() {        Map<ColourEnum, ColourHandler> map = new EnumMap<>();        map.put(WHITE, whiteColourHandler);        return map;    }}
