技术支持项目

版本：20220913

问题场景：某个项目同时部署一个rar格式的web应用和war包应用，同时部署是war应用可以正常访问；当需要局部更新，即重新部署rar格式的web应用，而不影响war应用的访问；

在之前的版本其中一个应用卸载是不会影响到另外一个war应用的，但这个版本应该有个bug

处理方案：

1.首先要确定这两个应用包是不是有一个可能是纯前端的应用，两个有关联关系，确定是的话让应用研发自行处理，确定方法;

使用tree命令在ApusicAS/aas/domains/mydomain/applications目录下获取应用的结构，如果是全部为html或css，jps啥的文件，就是纯前端，如果WEB—INF下包含有class类文件，就不是了

2.确定不是纯前端后，观察日志文件，可能有如下报错：

出现原因：这个可能是此版本的bug，当应用的访问路径设置为/根目录时，需要把虚拟服务器的根目录配置删掉

解决方法：
