使用 ipv6 访问应用程序时 Number Format 指针异常 URL

Question

我使用 Java 和 Spring MVC（版本 4.2.1.RELEASE）制作了一个简单的应用程序，并希望通过 Internet 访问它。但不幸的是，我的互联网提供商 (Jio Fiber) 不允许在 ipv4 网络上进行端口转发。所以我遇到的一个解决方案是使用 ipv6 地址代替访问本地主机，因为 ISP 允许这样做。

我遵循了解决方案并使用 ipv6 地址成功访问了我的本地主机。但是一旦我进行服务器调用（例如，从数据库中获取列表），我就会收到 java.lang.NumberFormatException 异常。堆栈跟踪如下：

SEVERE: Servlet.service() for servlet [spring] in context with path [/AgencyAccounting] threw exception [Request processing failed; nested exception is java.lang.NumberFormatException: For input string: "<>"] with root cause
java.lang.NumberFormatException: For input string: "201:8008:78e4:61a4:8a21:6b6c:a853]:8080"
