部署后未找到 Tomcat 页面错误

Question

在Tomcat服务器中部署代码后，我在浏览器中查看所有页面时都收到一条找不到的错误消息。

例如：- 未找到 /BOOKS/web/Index.html。

我在网络文件夹下有Index.html的文件。这是一个Spring-MVC框架应用程序。

下面是错误日志详细信息。

请帮帮忙。

您的依赖项中必须有两个版本的< code>bcprov-*:

1. 一个旧的（直到版本1.46），其中ASN1OutputStream扩展了DEROutputStream，
2. 最近的一个（从版本1.47开始），层次结构被颠倒：DEROutputStream扩展了ASN1OutputStream。

在Maven依赖项中查找名称以< code>bcprov-开头的多个依赖项，并检查应用程序的< code>WEB-INF/lib文件夹或Tomcat的公共类加载器(< code>$CATALINA_BASE和< code>$CATALINA_HOME的< code>lib文件夹)中是否没有其他版本。

编辑：对于Bouncy Castle（以及许多长期存在的库），多个版本的问题可能会因多个Maven工件（分为两组：bouncycastle和org.bouncycastle）而加剧，这些工件使用几乎相同的代码：bcprov-jdk14，bcprov-jdk15on，bcprov-jdk15to18等。有关示例，请参阅此问题。
