我无法从java API文档中找到ServletException的目的,虽然我们编写的覆盖服务方法会抛出ServletException,但是什么时候会抛出这个检查异常?
If there is any error with status code either 404 ( Not Found) or 403 ( Forbidden ) then the ServletException may be thrown
您收到此异常可能有多种原因。我记得我个人面临的一个问题是,由于没有足够的服务器内存,服务器无法分配/加载 servlet 实例。在堆栈 strace 中,它显示为“分配 servlet 实例时出错”。
