在controller里注入

    @Inject
    Dao dao;

注入失败

难道不能直接注入dao属性嘛?我看demo-simple-dao里为何可以呢?

nutz版本问题

额...我是让nb管理的nutz吧?

nutzboot-stater-nutz-dao里也看到了

 @IocBean(name = "dao")
    public NutDao getDao(@Inject DataSource dataSource, @Inject SqlManager sqlManager) {
        NutDao dao = new NutDao(dataSource, sqlManager);
        List<Object> interceptors = new ArrayList<>();
        // 是否启用了DaoCache呢?
        if (conf.getBoolean(PROP_INTERCEPTOR_CACHE_ENABLE, false)) {
            interceptors.add(ioc.get(DaoCacheInterceptor.class));
        }
        // 日志拦截器
        if (conf.getBoolean(PROP_INTERCEPTOR_LOG_ENABLE, true)) {
            interceptors.add("log");
        }
        // sql耗时拦截器
        if (conf.getBoolean(PROP_INTERCEPTOR_TIME_ENABLE, true)) {
            interceptors.add("time");
        }
        // TODO 自定义其他拦截器?

        // 将拦截器赋予dao对象
        dao.setInterceptors(interceptors);
        // 看看是不是需要注入从数据库
        if (Lang.loadClassQuite("org.nutz.boot.starter.jdbc.DataSourceStarter") != null) {
            DataSource slaveDataSource = DataSourceStarter.getSlaveDataSource(ioc, conf, "jdbc.slave.");
            if (slaveDataSource != null) {
                NutDaoRunner runner = new NutDaoRunner();
                runner.setSlaveDataSource(slaveDataSource);
                dao.setRunner(runner);
            }
        }
        return dao;
    }

可能是我引用的问题？

蛋蛋最帅(ฅ>ω<*ฅ)

输出一下依赖信息，看看实际nutz版本，还不行的话强制指定一下版本号

另一个模块引用的是1.r.53版本的,然后覆盖了starter里的1.r.66快照版,然后我将其他模块都改成1.r.66快照版就ok了
