一、困惑
代码如下,我要用 ILookupService 的方法 ,那我在任何一个要使用的类里都要 @Autowired 一下,如果是个类似工具类的方法到处使用那也太麻烦了
@Autowired private ILookupService lookupService; private List<PfLookup> getNameByCode(String code){ Map<String, Object> param = new HashMap<>(); param.put("code", code); List<PfLookup> lookups = lookupService.listLookupByCode(param); return lookups; }
二、解决办法
写一个静态工具类:
@Component public class ServiceManager { public static MerchantRepository merchantRepository; public static ILookupService lookupService; @Autowired public void setMerchantRepository(MerchantRepository merchantRepository) { ServiceManager.merchantRepository = merchantRepository; } @Autowired public void setLookupService(ILookupService lookupService) { ServiceManager.lookupService = lookupService; } }
这样在任何类里都可以直接使用了
ServiceManager.lookupService.方法名
如下:
public static String getNameByCode(String code){ Map<String, Object> param = new HashMap<>(); param.put("code", code); List<PfLookup> lookups = ServiceManager.lookupService.listLookupByCode(param); if(lookups.size() == 0){ logger.error("字典配置有误,code:[{}]", code); return "字典有误"; } return lookups.get(0).getName(); }
