我已经使用鳄梨酱三年了，从0.9.13开始。
扩展包含"auth jdbc mysql"；以及"；auth-cas"；我升级到1.1.0，一切正常，但当我更新到1.2.0时，它无法工作，如果我使用MySQL进行身份验证，它也可以很好地工作，但使用cas1.2，我在登录时得到了一块白板，所以我检查了日志，错误如下(来自logs/localhost.2020-11-24.log(，我不懂Java，这可能很容易，帮我谢谢。如果我替换，请使用cas1.1替换cas1.2，其他保持不变它也能很好地进行

当在1.2.0中实现公共重定向字段时，CAS模块中留下了几个组件，这些组件会在模块启用时导致下载app.js文件时出错。
