@Component
public class Setup {
    private static final Log log = Logs.get();
    private static Connection rabbitmq_conn;
    private static Channel rabbitmq_channel;

    @Autowired
    private Dao nutDao;

    @PostConstruct
    public void init() {
        try {
            // 环境检查
            if (!Charset.defaultCharset().name().equalsIgnoreCase(Encoding.UTF8)) {
                log.warn("This project must run in UTF-8, pls add -Dfile.encoding=UTF-8 to JAVA_OPTS");
            }
            
            Ioc ioc = Mvcs.getIoc();
            NutConfig config = Mvcs.getNutConfig();

这样根本获取不到IOC对象啊
