如何在枚举类中注入spring bean实例对象

	@Component
    private static class CustomInjector {
        @Resource
        private CustomService customService;

        private static CustomService innerCustomService;
        
        @PostConstruct
        private void postConstruct() {
            CustomInjector.innerCustomService= customService;
        }
    }

public static void testMethod() {
	 CustomInjector.innerCustomService.testMethod();
}
