tomcat - 在tomcat上部署 Play Framework

Question

我使用 play framework 6.2/servlet 2.5，我生成了 war 并将其部署在 tomcat 7/8/9 上(我尝试了所有版本)我得到了同样的错误:

我知道 play 6.2 不兼容，我想尽我所能。这是终点线吗？我还有希望...

有人吗？

我想你的意思是，你正在尝试使用 play2-war-plugin玩2.6。从该链接中的自述文件来看，play2-war-plugin 不支持 Play 版本 2.5.x，我相信它也不支持 2.6.x。所以尝试使用 play 2.4.x 进行测试/开发。如果您坚持使用 play 2.6.x 和当前版本的 play2-war-plugin，我会说这对您来说已经结束了。
