版主你好，我使用一对多生成的代码，附表的mapper.xml中报了下文中的错误，我在前边没有找到类似的问题，请帮我看一下吧

FreeMarker template error (DEBUG mode; use RETHROW in production!):
The following has evaluated to null or missing:
==> subTab.originalForeignKeys [in template "java\\${bussiPackage}\\${entityPackage}\\mapper\\xml\\[1-n]Mapper.xml" at line 2, column 32]

----
Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
----

----
FTL stack trace ("~" means nesting-related):
- Failed at: #assign originalForeignKeys = subTab... [in template "java\\${bussiPackage}\\${entityPackage}\\mapper\\xml\\[1-n]Mapper.xml" at line 2, column 1]

新生成的代码无论查询还是插入都org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): org.jeecg.modules.ngalain.mapper.NgAlainMapper.insert 代码没放到modules里面，但改了包扫描，编译文件各种xml mapper都在，求解。

我的问题已经解决。在生成一对多代码的main方法中，附表配置的最后方没有写这行代码po.setOriginalForeignKeys(new String[]{"字表外键字段"});
加上这行代码就没有报错了

版主您好，前端问题，我在页面系统管理—用户管理，新加了个路由组件，然后刷新页面之后，再去登录页面， network提示调动了login接口,queryByUser接口，还有logout接口，并且logout接口报404，这种事什么问题导致的，是因为我新加路由的时候组件写错了，还是什么问题

您好,请问我在点击刷新验证码的时候出现这个问题是怎么回事呢?Parameter conditions "shortcut_top" not met for actual request parameters

我启动项目，登录后首页网页左侧的文字显示乱码，用户名也是名字。

您好请问一下我在此标签中
<t:dgCol title="用户名" field="userName" query="true" queryMode="single" width="120"></t:dgCol>
增加query="true" 页面搜索效果出来了，但是为什么数据不能查

前端访问 http://localhost:3000 会跳转至登录页，这是在哪里配置的？
