+[[use-path-pattern]]
+== Use PathPatternRequestMatcher by Default
+
+In Spring Security 7, `AntPathRequestMatcher` and `MvcRequestMatcher` are no longer supported and the Java DSL requires that all URIs be absolute (less any context root).
+At that time, Spring Security 7 will use `PathPatternRequestMatcher` by default.
+
+To check how prepared you are for this change, you can publish this bean:
+
+[tabs]
+======
+Java::
++
+[source,java,role="primary"]
+----
+@Bean
+PathPatternRequestMatcherBuilderFactoryBean requestMatcherBuilder() {
+	return new PathPatternRequestMatcherBuilderFactoryBean();
+}
+----
+
+Kotlin::
++
+[source,kotlin,role="secondary"]
+----
+@Bean
+fun requestMatcherBuilder(): PathPatternRequestMatcherBuilderFactoryBean {
+    return PathPatternRequestMatcherBuilderFactoryBean()
+}
+----
+======
+
+This will tell the Spring Security DSL to use `PathPatternRequestMatcher` for all request matchers that it constructs.
+
+In the event that you are directly constructing an object (as opposed to having the DSL construct it) that has a `setRequestMatcher` method. you should also proactively specify a `PathPatternRequestMatcher` there as well.
+
+For example, in the case of `LogoutFilter`, it constructs an `AntPathRequestMatcher` in Spring Security 6:
+
+[method,java]
+----
+private RequestMatcher logoutUrl = new AntPathRequestMatcher("/logout");
+----
+
+and will change this to a `PathPatternRequestMatcher` in 7:
+
+[method,java]
+----
+private RequestMatcher logoutUrl = PathPatternRequestMatcher.path().matcher("/logout");
+----
+
+If you are constructing your own `LogoutFilter`, consider calling `setLogoutRequestMatcher` to provide this `PathPatternRequestMatcher` in advance.
+
+== Include the Servlet Path Prefix in Authorization Rules
+
+For many applications <<use-path-pattern, the above>> will make no difference since most commonly all URIs listed are matched by the default servlet.
+
+However, if you have other servlets with servlet path prefixes, xref:servlet/authorization/authorize-http-requests.adoc[then these paths now need to be supplied separately].
+
+For example, if I have a Spring MVC controller with `@RequestMapping("/orders")` and my MVC application is deployed to `/mvc` (instead of the default servlet), then the URI for this endpoint is `/mvc/orders`.
+Historically, the Java DSL hasn't had a simple way to specify the servlet path prefix and Spring Security attempted to infer it.
+
+Over time, we learned that these inference would surprise developers.
+Instead of taking this responsibility away from developers, now it is simpler to specify the servlet path prefix like so:
+
+[method,java]
+----
+PathPatternRequestParser.Builder servlet = PathPatternRequestParser.servletPath("/mvc");
+http
+    .authorizeHttpRequests((authorize) -> authorize
+        .requestMatchers(servlet.pattern("/orders/**").matcher()).authenticated()
+    )
+----
+
+
+For paths that belong to the default servlet, use `PathPatternRequestParser.path()` instead:
+
+[method,java]
+----
+PathPatternRequestParser.Builder request = PathPatternRequestParser.path();
+http
+    .authorizeHttpRequests((authorize) -> authorize
+        .requestMatchers(request.pattern("/js/**").matcher()).authenticated()
+    )
+----
+
+Note that this doesn't address every kind of servlet since not all servlets have a path prefix.
+For example, expressions that match the JSP Servlet might use an ant pattern `/**/*.jsp`.
+
+There is not yet a general-purpose replacement for these, and so you are encouraged to use `RegexRequestMatcher`, like so:  `regexMatcher("\\.jsp$")`.
+
+For many applications this will make no difference since most commonly all URIs listed are matched by the default servlet.
