Inject bean into enum

Question

I have the DataPrepareService that prepare data for reports and I have an Enum with report types, and I need to inject ReportService into Enum or have access to ReportServic

Answer 1

it will be hard to control that the spring container is already up and running at the time the enum is instantiated (if you had a variable with this type in a test-case, your container will usually not be there, even aspectj autowiring won't help there). i would recommend to just let the dataprepare-service or something give you the specific-params with a lookup-method with the enum-parameter.

Answer 2

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);
        }
    }

[...]

}

weekens' answer works if you change inner class to static so spring can see it
