У меня проблема с запуском моего весеннего проекта MVC. Я пробовал разные решения для переполнения стека и других сайтов сообщества, но все еще не смог решить проблему, я не знаю, в чем конкретно проблема, Какие варианты я пробовал,я.Изменил мою версию затмения с Марса на затмение Фотон II.Мне сказали изменить версию JDK, так как я использую только JDK 8,65, только у меня не установлены другие версии.III.Я изменил свой сервер Tomcat с 7 до 8,5, все еще получая ту же ошибку.
Ниже приведена трассировка стека, полученная при запуске проекта.
