Inject bean into enum

public enum ReportType {    REPORT_1("name", "filename"),    REPORT_2("name", "filename");    @Component    public static class ReportTypeServiceInjector {        @Autowired        private DataPrepareService dataPrepareService;        @PostConstruct        public void postConstruct() { for (ReportType rt : EnumSet.allOf(ReportType.class))    rt.setDataPrepareService(dataPrepareService);        }    }[...]}

如果将内部类更改为静态，则weekens的答案有效，因此spring可以看到
