我试了一下, 如果IndexModule没加@IocBean的话会报这个错误

qq_85df1dfe 8楼•2346天前

module不是会扫描的吗

wendal

9楼•2346天前

@At跟@IocBean是两个独立的东西,感觉是nutz库的bug,待我查查

qq_85df1dfe 10楼•2346天前

我试了一下，如果在类上加上@At 就好了建议修复一下

qq_85df1dfe 11楼•2346天前

我错了，加了at只是不报错了，映射好像还没加上

12楼•2346天前

加上@IocBean能好,我找到原因了. 你要报issue不? https://github.com/nutzam/nutz/issues

qq_85df1dfe 13楼•2346天前

不报了吧，这个问题挺复杂，我描述不好。
怎么总感觉有一种缓存的存在，我改成这样

    @At("/index")
    @Ok("jsp:/in.jsp")
    public String index(int page,int size,ViewModel viewModel){

        return "t";
    }

还是可以进去index.jsp 项目也重启了几次了

qq_85df1dfe 14楼•2346天前

idea的debug也没进去

qq_85df1dfe 15楼•2346天前

知道了，原来是因为我刚才类上加的at没去掉，去掉后就行了
