配置spring启动完成后执行的代码

所需service implements ApplicationListener<ContextRefreshedEvent>
在onApplicationEvent方法体内写所需代码

@Service
public class WhiteIpServiceImpl implements WhiteIpService , ApplicationListener<ContextRefreshedEvent>

@Override
    public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
        list =  whiteIpMapper.findAll();
    }
