Question

我想将三个属性（companyTypes，carrierLists和cabinLevels）初始化为全局变量：

@Controller
@RequestMapping("/backend/basic")
public class TicketRuleController {
    @Autowired
    private CarrierService carrierService;
    @Autowired
    private CabinLevelService cabinLevelService;
    @Autowired
    private CompanyTypeService companyTypeService;
    private List<DTOCompanyType> companyTypes = companyTypeService.loadAllCompanyTypes();
    private List<DTOCarrier> carrierLists = carrierService.loadAllCarriers();
    private List<DTOCabinLevel> cabinLevels = cabinLevelService.loadAllCabinLevel(); 
    ...
}

我该怎么做？

Answer 1

完成依赖项注入后，有几种方法可以执行初始化：您可以在某些方法上使用@PostConstruct注释。例如：

@PostConstruct
public void initialize() {
   //do your stuff
}

或者您可以使用Spring的InitializingBean界面。创建一个实现此接口的类。例如：

@Component
public class MySpringBean implements InitializingBean {


    @Override
    public void afterPropertiesSet()
            throws Exception {
       //do your stuff
    }
}

您应该能够添加默认构造函数以进行初始化。

public TicketRuleController() {
    super();
    // Init yours properties here.
}

如何通过Spring在Controller中添加构造函数
