As of Spring Framework 5.3, Spring MVC supports several implementation strategies for matching request paths to Controller handlers.
It was previously only supporting the `AntPathMatcher` strategy, but it now also offers `PathPatternParser`.
Spring Boot now provides a configuration property to choose and opt in the new strategy:
As of Spring Framework 5.3, Spring MVC supports two strategies for matching request paths to controllers.
By default, Spring Boot uses the `PathPatternParser` strategy.
`PathPatternParser` is an https://spring.io/blog/2020/06/30/url-matching-with-pathpattern-in-spring-mvc[optimized implementation] but comes with some restrictions compared to the `AntPathMatcher` strategy.
`PathPatternParser` restricts usage of {spring-framework-docs}/web.html#mvc-ann-requestmapping-uri-templates[some path patterns variants].
It is also incompatible with suffix pattern matching (configprop:spring.mvc.pathmatch.use-suffix-pattern[deprecated], configprop:spring.mvc.pathmatch.use-registered-suffix-pattern[deprecated]) and configuring the `DispatcherServlet` with a path prefix (configprop:spring.mvc.servlet.path[]).
The strategy can be configured using the configprop:spring.mvc.pathmatch.matching-strategy[] configuration property, as shown in the following example:
and is incompatible with suffix pattern matching (configprop:spring.mvc.pathmatch.use-suffix-pattern[deprecated],
configprop:spring.mvc.pathmatch.use-registered-suffix-pattern[deprecated]) or mapping the `DispatcherServlet`
with a servlet prefix (configprop:spring.mvc.servlet.path[]).
By default, Spring MVC will send a 404 Not Found error response if a handler is not found for a request.
To have a `NoHandlerFoundException` thrown instead, set configprop:spring.mvc.throw-exception-if-no-handler-found to `true`.
Note that, by default, the <<web#web.servlet.spring-mvc.static-content, serving of static content>> is mapped to `+/**+` and will, therefore, provide a handler for all requests.
