#Service层

1、默认数据源

@Service
public class BaseUserInfoServiceImpl extends ServiceImpl<BaseUserInfoMapper, BaseUserInfo> implements IBaseUserInfoService {
 
}

2、sqlserver-bz数据源

@Service
@DS("sqlserver-bz")
public class YhbServiceImpl extends ServiceImpl<YhbMapper, Yhb> implements IYhbService {
 
}

3、sqlserver-yw数据源

@Service
@DS("sqlserver-yw")
public class ZybrxxbServiceImpl extends ServiceImpl<ZybrxxbMapper, Zybrxxb> implements IZybrxxbService {
 
}
