Using Bean objects in spring static methods

Method:

Create a static Bean object in the class, and then initialize the bean using init, so that you can invoke it in a static method

    @Service ("IDG") public
    class Idgenerator {
     
        @Autowired
        private Iidgeneratordao DAO;
     
        private static Idgenerator generator;
     
        public void Setdao (Iidgeneratordao dao) {
            This.dao = DAO;
        }
     
        @PostConstruct public
        Void, init () {
            generator = this;
            Generator.dao = This.dao;
        }
     
        @Transactional public
        static String getId () {
            return generator.dao.getId ();
        }
     
        @Transactional public
        static string GetId (string name) {
            return generator.dao.getId (name);
        }
}
