本文解决了一个关于web.xml中配置的安全约束URL模式问题。错误模式为/beer/*.jsp，正确的模式应为/beer/*，以确保对/beer路径下所有文件进行保护。

The exact problem with this pattern: "/beer/*.jsp "

Is that it starts with a '/', indicating a path mapping, and ends with and extension mapping.

URL-patterns must be one of the following:

- start with a '/' and end with a '/*', use this one for path patterns
- start with a '*.' and end with a character, use this for extension mapping
- some sequence of characters starting with '/' and not ending in '*', use this for exact matches.

If you want to secure the /beer pages, then the pattern should be "/beer/*"
