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]

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 ...

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
