Answer 1

我不直接知道你问题的答案，但这是我接近它的方法：

首先，如果我正确理解您的问题，您希望转到网址http://localhost:8080/SpringExample会将您重定向到登录页面，但这不会发生（您看到的是404）。我假设您已经检查过您的应用程序实际部署到SpringExample上下文。

您可能会遇到几个可能影响URL解释和重定向的事情。首先，你有Spring，它将以/ pages /开头的任何请求映射到Spring调度程序。接下来，你有一些URL重写，因为它是在过滤器中完成的，应该在spring dispatcher servlet之前进行。你还有一个加载所有弹簧上下文配置的监听器。第三，你有一个在过滤器中实现的Spring Security。最后，您已经获得了tile配置，如果找不到资源，理论上也可能导致404错误，尽管看起来你的确定没问题。

这非常复杂，如果事情没有以正确的顺序发生，你就会遇到问题。我要做的是去除每个组件，然后开始逐个添加它们。首先，除欢迎文件配置外，取出所有内容，看看是否可以通过转到您的网址到达/index.jsp。然后重新添加Spring，看看你是否仍然可以使用它。然后添加URL重定向，然后添加安全性，然后添加切片。这有助于您缩小问题范围。
