public class GalaxyCalAppSlotsRepo { @Autowired GalaxyCalAppSlotsDAO galaxyCalAppSlotsDAO; public void insertAppSlotsRecord(String appCode,String executeType, int slotCount) { GalaxyCalAppSlotsDO galaxyCalAppSlotsDO = new GalaxyCalAppSlotsDO(); galaxyCalAppSlotsDO.setAppCode(appCode); galaxyCalAppSlotsDO.setExecuteType(executeType); galaxyCalAppSlotsDO.setSlotsCount(slotCount); galaxyCalAppSlotsDAO.insertSelective(galaxyCalAppSlotsDO); } }以上方法如何在public interface ResourceFacade { BaseResult<Boolean> setGalaxyCalAppSlots(); }方法去调用它，如果此appCode已经存在抛异常告知已经存在，并对slotCount设置一个初始值，slotCount也可以扩大跟缩小java代码如何实现

可以先在ResourceFacade中注入GalaxyCalAppSlotsRepo，在setGalaxyCalAppSlots方法中调用insertAppSlotsRecord方法，并在方法中进行appCode是否存在的判断，如果存在则抛出异常，否则设置初始值并插入到数据库中。代码如下：

public interface ResourceFacade {
    BaseResult<Boolean> setGalaxyCalAppSlots(String appCode, String executeType, int slotCount);
}

@Service
public class ResourceFacadeImpl implements ResourceFacade {
    @Autowired
    private GalaxyCalAppSlotsRepo galaxyCalAppSlotsRepo;
    
    @Override
    public BaseResult<Boolean> setGalaxyCalAppSlots(String appCode, String executeType, int slotCount) {
        try {
            // 判断appCode是否存在
            GalaxyCalAppSlotsDO galaxyCalAppSlotsDO = galaxyCalAppSlotsRepo.selectByAppCode(appCode);
            if (galaxyCalAppSlotsDO != null) {
                throw new RuntimeException("appCode已存在");
            }
            
            // 设置初始值并插入数据库
            galaxyCalAppSlotsRepo.insertAppSlotsRecord(appCode, executeType, slotCount);
        } catch (Exception e) {
            return new BaseResult<>(BaseResult.FAILURE, e.getMessage(), false);
        }
        return new BaseResult<>(BaseResult.SUCCESS, "插入成功", true);
    }
}

@Repository
public interface GalaxyCalAppSlotsDAO {
    int insertSelective(GalaxyCalAppSlotsDO record);
    
    GalaxyCalAppSlotsDO selectByAppCode(String appCode);
}

@Service
public class GalaxyCalAppSlotsRepo {
    @Autowired
    private GalaxyCalAppSlotsDAO galaxyCalAppSlotsDAO;
    
    public void insertAppSlotsRecord(String appCode, String executeType, int slotCount) {
        GalaxyCalAppSlotsDO galaxyCalAppSlotsDO = new GalaxyCalAppSlotsDO();
        galaxyCalAppSlotsDO.setAppCode(appCode);
        galaxyCalAppSlotsDO.setExecuteType(executeType);
        galaxyCalAppSlotsDO.setSlotsCount(slotCount);
        galaxyCalAppSlotsDAO.insertSelective(galaxyCalAppSlotsDO);
    }
}
