Routing with regular expressions

正则还可以被使用在URI路径的匹配上：

Route route = router.route().pathRegex(".*foo");
route.handler(routingContext -> {
  // This handler will be called for:
  // /some/path/foo
  // /foo
  // /foo/bar/wibble/foo
  // /foo/bar
  // But not:
  // /bar/wibble
});

还有一种做法是,正则可以在创建route时进行指定.

Route route = router.routeWithRegex(".*foo");
route.handler(routingContext -> {
  // This handler will be called same as previous example
});
